The Climate Challenge Game Rules
The game is based on the TV show College Bowl (University Challenge).
The Rules:
- There are five rounds in this game, with 10 or more questions
in each round. The quizmaster (generally the teacher) has the correct
answers,
and should be able to explain them, and answer follow-up questions,
and lead the discussion. The quizmaster keeps score for the competing
teams on the blackboard.
- Two students are asked to act as referees for each round. In the
event of a close call, their job is to decide which team called out
their answer first. They can also participate in the game by keeping
track
of their own answers and scores (see 5 below).
- Each round is played by two teams of three members each, who sit
in front of the class. Both teams need pens and paper, to make notes.
(Each round has six people in two teams, allowing 24 students to
participate over the four rounds. If there are less than 24, use whatever
means you
like to make up the team numbers. If there are more than 24, the
teams should be larger.)
- Each team chooses a name, and a word or noise that they will call
out to indicate when they are ready with an answer. The class as
a whole can choose how to congratulate the winning team.
- Round 1 (Climate Change) has 10 questions, and three bonus
questions.
- Round 2 (Impacts) has 11 questions.
- Round 3 (Global Solutions) has 16 questions.
- Round 4 (Local Solutions) has 12 questions.
- Round 5 (Personal Solutions) has 21 questions.
- Every student not on a team takes a piece of paper, and draws
three columns, to track their own score:
| Question |

Each time a question is asked, everyone who is not on a team writes
their answer in Column 2, and keeps score of their personal results.
At the end of each round, they add up their scores to see who has
the highest.
- Each time a question is asked, the team members discuss it, and
agree on their answer. As soon as they are ready, they call out their
word
or noise. The Quizmaster then asks them the question. If they are
correct, they win the points associated with the question. If they
are wrong,
the other team is given 10 seconds to answer the question.
- If both teams get the answer wrong, the question goes to the class.
The first student who answers the question correctly wins the points
for that question. He or she also has a chance to explain why that
is the correct answer. If he or she can do this to the satisfaction
of the
Quizmaster, he or she wins twice the value of the points for that
question. After any question, the Quizmaster may ask any student who
is not in
a team to volunteer to explain why this is the correct answer. A
good answer earns 10 bonus points; a middling answer earns 5 bonus
points.
A disruptive answer loses 5 points.
- As Quizmaster, you may arbitrarily increase the points that can
be won for the final three questions to encourage the team that is
behind.
- After each Round, the points are tallied up, and the winning team
is announced. The students who are not in a team also add up their
points, and the Quizmaster invites anyone to call out a score, to see
who has
won. The two winning students are invited to head up the next two
teams, based on the birthdates of other students closest them. Each
student
can only join a team once.
Round 1: Understanding Climate Change
QU. 1 (5 points). What warms the Earth, so that humans, animals and
plants can live on it?
- Heat from the Earth’s molten core
- Heat from the Sun
- Heat from the stars in the galaxy
- Heat from baked beans
Answer: (b) Heat from the Sun.
The molten core of
the earth radiates a tiny amount of heat upwards, but not enough to
warm anything, except
in hotsprings. The stars produce such a tiny fragment of heat that
it’s
not even really measurable. Baked beans could produce secondary heat,
if the methane gas that sometimes results from their consumption was
trapped and burnt, but they have to be grown first.
QU. 2 (10 points). What does the Earth’s atmosphere do?
- It traps heat from the sun, keeping life on Earth warm
- It allows light to reach the Earth, enabling photosynthesis
to take place
- It assists gravity with atmospheric pressure, making things
heavy, to stop them floating away
- It allows Earth to receive cosmic rays and signals from other
stars
Answer: (a) It traps heat from the sun, keeping life on Earth warm.
QU. 3 (10 points). What would happen if Earth did not have an atmosphere?
- Everyone would die from the heat of the sun
- Everyone would freeze from the cold of the night
- Humans would never have evolved
- The Earth would have been destroyed by asteroids
Answer: (c) Humans would never have evolved.
Answers (a) and (b) might be correct if the atmosphere was
suddenly removed today, but there is no sign that anything might do
this.
Answer (d) is a risk, but not a certainty.
Answer (c) is a certainty, so wins the point.
QU. 4 (10 points). What is a greenhouse gas?
- A gas that is part of the ozone layer that protects the Earth
against harmful rays from space
- A gas that comes from cars, trucks and planes, causing smog
and air pollution
- A gas that is used to make tomatoes grow faster in a greenhouse
- A gas that traps the Earth’s heat, after it has arrived
from the Sun
Answer: (d) A gas that traps the Earth’s heat, after it has
arrived from the Sun
Ozone depletion is a separate problem, caused by chlorine
based gases (CFCs and HCFCs), and has only a distant connection to
global climate
change.
Smog and pollution are also caused by burning fossil fuels, but it’s
the carbon dioxide that is the greenhouse gas. On its own, CO2 does
not cause smog or local air pollution
QU. 5 (10 points). Which of these planets
has the strongest greenhouse effect?
- Earth
- Mars
- Venus
- Jupiter
Answer: (c) Venus
Bonus Points (2 points each):
(1) Do you know how hot it is on Venus, which has a very strong greenhouse
effect?
(2) Do you know how cold it is on Mars at night, which has no greenhouse
effect?
Answers: Venus has so much CO2 in its atmosphere that its average
temperature is 460ºC.
Mars has so little CO2 in its atmosphere that it is 37°C when the
sun shines, but minus 123ºC at night.
QU. 6 (10 points). What are fossil fuels made from?
- Ancient rocks, turned into coal or oil by heat from the Earth’s
core
- Dead dinosaurs, compressed together over millions of years
- Ancient carbon-based plant matter and ocean life
- Ancient protoplasm, melted by nuclear fusion from the Earth’s
molten core
Answer: (c) Ancient carbon-based plant matter and ocean life.
The ancient rocks and ancient protoplasm answers are total nonsense.
There may be the occasional fragment of dinosaur remains locked up
in
some coal, but not enough to be any use.
QU. 7 (5 points). Which of the following is not a fossil fuel?
- (a) Natural gas
- (b) Oil
- (c) Coal
- (d) Marmalade
Answer: (d) Marmalade
Bonus 10 points to anyone not on a team who can anyone explain why
marmalade is not a fossil fuel. Five points for an adequate, but
not great answer.
QU. 8 (15 points). Which of these four greenhouse gases do fossil fuels
release, when they are burned?
- (a) Water vapour
- (b) Carbon dioxide
- (c) Methane
- (d) Ozone
Answer: (b) Carbon dioxide
Fossil fuels also release some water vapour, but its addition to
the vast quantity of water vapour that’s already in the atmosphere
is insignificant.
Fossil fuels often release methane before they are burnt; but as
soon as the methane burns, it is converted to CO2.
Ozone is produced by a mixture of pollutants that come from burning
fossil fuels, but it is not released directly.
QU. 9 (10 points). Which of these activities does not contribute to
global climate change?
- Driving a car that burns gasoline
- Driving a car that burns natural gas
- Driving an electric car that uses electricity from a coal-fired
power plant
- Driving a car that burns biodiesel made from waste fats from
restaurants
Answer: (d) Driving a car that burns biodiesel made from waste fats
from restaurants
Gasoline, natural gas and the coal that is burnt to make the power
for an electric vehicle are all fossil fuels, so the CO that they
release
contributes to global climate change. Biodiesel that is made from waste
fats from restaurants originates in the plant material that was used
to make the restaurant fats, and the plants absorbed CO2 before they
were processed to make the fats, so they are part of the natural carbon
cycle, and do not contribute to global climate change.
QU. 10 (10 points). Methane is also a greenhouse gas. Which of the following
four sources does not generate methane?
- Swamps, and rotting underwater vegetation
- Emissions from natural gas vehicles
- Cows burping, from their two stomachs
- Landfills, that hold rotting garbage
Answer: (b). The methane that is in natural gas breaks down into CO2
when it is burnt in a car.
- When the carbon in plant material breaks down in the presence
of oxygen, it forms CO2.
- When it breaks down in the absence of oxygen, it forms methane
(CH4).
- Methane comes from swamps, and rotting underwater vegetation;
from landfills (where there is no oxygen as the material breaks down),
and
from the
stomachs of cows, where there is also no oxygen. It is
released when cows burp.
In the event of a close finish:
QU. 11: how many greenhouse gases can you name?
Each team takes it in turn to name a gas, starting with the
team with the lower score.
2 Bonus points per correct answer.
Answers: Carbon dioxide – methane – nitrous oxide – Family of
CFCs & HCFCs & HFCs – perfluorocarbons – sulfur hexafluoride – tropospheric
ozone – water vapour
- Nitrous oxide comes from poor soil management, where the nitrogen
in fertilizers is released into the air; from transportation
pollution; and from some industrial processes.
- Perfluorocarbons (PFCs) come from the manufacture of aluminum,
solvents and plasma.
- Sulfur hexafluoride (SF6) comes from the production of magnesium.
- Tropospheric ozone is produced by air pollution by transport and
industry
- Water vapour is caused by evaporation of the world’s oceans.
It is the primary natural greenhouse gas, but it is not being increased
by human activity in sufficient quantity to make any difference.
The Winning Team receives a big round of applause, and the teams join
the rest of the class.
Round 2: Climate Change Impacts
QU. 1 (10 points). This question concerns the impact of global warming
on the Arctic Ocean ice. If global warming continues, the summer ice
could be all gone by 2050, and the year-round ice by 2100. This will
affect the polar bears in various ways. Which of these four effects will
be the most serious and life threatening to the bears, as the ice melts?
- There will be a shorter season when they can hunt for walrus,
so the bears will slowly starve to death.
- The increased rain and warmer temperatures will cause the snow
dens where the female raise their cubs to collapse, while the
cubs are still
very small and vulnerable.
- There will be a shorter season when they can hunt for ringed
seals, so the bears will slowly starve to death.
- There will be fewer tourists standing around on the ice,
making for easy prey, so the bears will slowly starve to
death.
Answer: (c). The ringed seal is the bear’s main diet, and for
every week that the ice melts earlier, causing them to leave the ice
and stop hunting, the bears lose 10 kg of weight.
Re (a): Polar bears do also eat walrus, but it is not their main diet.
Re (b): This is a serious danger to the bears, but the female bears will
build another den, if one den collapses.
Re (d): The tourists never had much flesh on them, and the artificial
fibre that they use for their winter gear tastes horrible, anyway, so
they were never a large part of the bears’ diet.
QU. 2 (10 points). As the temperature warms, the permafrost that covers
most of the Arctic and northern lands is melting. Which of these four
impacts is being caused by the melting permafrost?
- The ice-roads which people use to cross lakes and rivers in
the winter are melting earlier, and have to be closed, since they
are no longer
safe.
- The large quantities of methane gas from ancient rotting vegetation
that is stored in the permafrost is escaping, and may explode
in a dangerous manner.
- The land underneath houses, roads and bridges is collapsing,
causing them to buckle and become dangerous.
- It is becoming more dangerous to travel over land by snowmobile,
since there are frequent patches of water and bare earth
where there used to be snow.
Answer: (c). This is a big problem in Alaska and
northern Canada. 50% of Canada’s land is underlain by permafrost, and to remain frozen,
it needs a year-round temperature below 0ºC. Most houses and roads
in the North do not have deep foundations, so as the permafrost melts,
they can sag, buckle and collapse.
Re (a). The melting ice-roads are a result of the melting ice, not
the melting permafrost.
Re (b). Methane gas is escaping from the permafrost, and this is a
concern, since methane is also a greenhouse gas, but it does not explode,
since
it is not concentrated in one place.
Re (d). This is another result of climate change - caused by melting
snow, not melting permafrost.
QU. 3 (10 points). This is a question about the global sea level. Scientists
on the United Nations Intergovernmental Panel on Climate Change have
studied the sea level, and they say it will rise by up to a metre by
2100, because of climate change. Which of these four reasons do they
say is the reason for this rise in sea level?
- The expansion of the water molecules in the sea, which is
caused by the higher temperature of the water.
- The increase in fresh water that is running into the oceans,
as a result of increased rainfall around the world.
- The melting of the Greenland and Antarctic ice caps.
- The melting of the Arctic ice cap.
Answer: (a). As water warms, its molecules expand. Thirty of
the world’s
major cities are close to sea level, including London, New York and Shanghai
in China, and are threatened with serious flooding.
Re: (b). Rainwater accumulates in the sky by evaporation from the oceans.
As the ocean surface warms, there is more evaporation, resulting in more
rainfall, but this does not cause sea levels to rise.
Re: (c). This is a big concern in the long-term, since Greenland’s
ice cap sits above sea-level – some of it more than 3000 metres
above sea level. The Antarctic ice cap is also above sea-level, and up
to 2700 metres thick. There is some evidence that the ice in Greenland
and the west Antarctic ice sheet is melting faster than normal, but it
is not yet clear enough to have been included in the scientists’ predictions.
Re: (d) The Arctic ice cap is already floating in the sea, so when it
melts, it does not cause the sea level to rise.
QU. 4. This question is about the different animals
and plants in Canada’s
North, that will be affected by climate change. Each team will take it
in turn to call out the name of a creature or plant that will be affected
by climate change live in Canada’s North, and explain why it will
be affected. There are no penalty points for suggesting a wrong answer.
For each correct answer, a team wins 2 points. For each correct explanation,
that team wins an additional 3 points, creating a possible 5 points
for each creature or plant affected. If Team A can not provide a
good explanation,
the opportunity is offered to Team B.
Possible Answers:
- Arctic char need really cold water, and will move to areas of
the Arctic that are colder.
- Arctic ground squirrels: When the snow is deeper, the squirrels
raise more babies.
- Brown bears have been spotted on the Arctic shoreline for the
first time in memory.
- Caribou: There will be fewer numbers, due to deep snow and frozen
crust, earlier break-up of rivers and lakes, and difficulty in
getting to calving
grounds
- Fish: As the permafrost melts, dirt and sediment falls into the
rivers and is washed into the sea, making it difficult for fish
to breathe and
spawn.
- Moose: The warmer, wetter weather is causing willows to grow faster,
providing more food.
Mosquitoes are encouraged by the warmer weather
- Parasites and bugs: The warmer weather causes more parasites,
which bothers the moose, caribou, sheep, & lynx
Plants, shrubs and trees are moving northwards as the temperatures
warm and moisture levels change, replacing the tundra environment.
As the
permafrost melts, trees are toppling, and new wetlands are
being created, while other wetlands drain and dry up.
- Polar bears: Less ice means less time when they can hunt for food.
See Qu. 1 above, too
- Ringed seals: Less ice means less opportunity to raise their young
in safety
- Salmon: Pacific salmon are seeking out new rivers in the Arctic
where they can breed, as the ocean warms.
- Songbirds. There is an observed decline in their numbers. This
may be related to climate change; it may also be caused
by a loss of
the summer
habitat, in Canada, the USA and Mexico.
- Turkey vultures are moving north. One was caught at For McPherson
in 2002, where they have never been seen before.
- Walrus: Less ice means fewer places where they can raise their
young in safety.
- Whitetail deer coyotes and cougars: All being seen further
north than normal.
QU. 5 (10 points). This is a question about the increasing global
temperatures that scientists are predicting. The average global temperature
increased
by 0.6°C between 1900 and 2000. Some regions in the Arctic warmed
by as much as 5°C in the same period. According to the scientists’ computer
models, how much warmer might the Earth become by 2010?
- 2.8ºC
- 3.8ºC
- 4.8ºC
- 5.8ºC
Answer: (d). The computer models used in the 2001
United Nations report on climate change showed a number of possible
future temperatures, ranging
from 1.4ºC to 5.8ºC. A study by British scientists at the Hadley
Centre for Climate Prediction and Research in England, which was published
after the UN report, has predicted a global rise of 8ºC by 2100.
QU. 6 (10 points). This is a question about the impact of global
climate change on Canada’s forests. Which one of these four statements
is most correct?
- The biggest danger to the forests comes from increased forest
fires, because of the hot, dry summers
- The biggest danger to the forests comes from increased rainfall
and snow, which causes mudslides and avalanches.
- The biggest danger to the forests comes from increased damage
by pests, which like the warmer weather.
- The biggest danger to the forests comes from increased tourism,
logging, and oil and gas activity, which is made easier
by the warmer weather.
Answer: (c). Pests. In British Columbia, by 2003,
the mountain pine beetle had destroyed more than 600,000 hectares of
forest, more than
the whole of Sweden.
Re (a). Fire. In the record-breaking forest fire
season of 2003, BC lost 263,000 hectares to fire. The normal annual
loss is 33,000 hectares.
Re (b). Mudslides and avalanches are dangerous to humans, but not
to forests.
Re (d). The warmer weather is making it harder for logging and industrial
operations to happen in the north, not easier, because of the melting
permafrost.
QU. 7 (10 points). This question is about the increasing number of storms,
floods and weather-related disasters around the world that are being
caused by climate change. Which of the following kinds of disaster is
not linked to global climate change?
- Sudden downpours, floods and mudslides
- An increase in the number of earthquakes
- Extreme heatwaves
- Extreme droughts
Answer: (b). There is no known connection between climate change and
earthquakes. All of the others are showing a clear increase. The global
re-insurance industry, which provides insurance for the insurance companies,
is alarmed at the growing cost of insurance claims that are related to
climate change.
QU. 8. This is a question about the impacts that global
climate change is having – or will have – on businesses
in Canada. Each team will take it in turn to call out the name of a
type of business
that will be affected by climate change in Canada, and explain why it
will be affected. There are no penalty points for suggesting a wrong
answer.
For each correct answer, a team wins 2 points. For each correct explanation,
that team wins an additional 3 points, creating a possible 5 points
for each business affected. If Team A cannot provide a good explanation,
the opportunity is offered to Team B.
Possible Answers:
- Farming: Possible increased production in the North, as a result
of the warmer weather. Possible decreased production, from more
droughts and
heat waves.
- Fishing: Some fish species will benefit from the warmer water,
others will not.
- Forestry: Losses from pest damage, forest fires, and a higher
growing temperature (= less growth).
- Hunting: Ringed seals, walrus and caribou will all become scarcer.
- Insurance: Increased claims from disasters.
- Oil and gas: Production could increase, as year round ocean drilling
becomes possible. It could also decrease, as drilling
on the tundra becomes more difficult, with the melting permafrost.
- Shipping: New Arctic routes will open up.
- Skiing: Loss of snow cover
- Solar and wind energy: Production will increase, as an alternative
to diesel, oil, coal and gas.
- Tourism: Arctic tourism could increase, with the warmer
weather in summer
QU. 9 (10 points). This is a question about the HUMAN HEALTH IMPACTS
of global climate change. Which of these four diseases, all of which
are increasing in the world, is causing the greatest suffering due to
global climate change?
- (a) SARS (Sudden Acute Respiratory Virus)
- (b) West Nile Disease
- (c) Malaria
- (d) Mad Cow Disease
Answer: (c). Malaria is spread by malaria-carrying mosquitoes, which
are moving north as the climate warms. Malaria kills millions of people
every year, mostly in the developing nations.
Re (a) SARS is not caused by global climate change. It is probably
caused by a virus that crosses to humans from wild animals that are
captured
for food in China.
Re (b) West Nile Virus is carried by mosquitoes which are moving north
as the climate warms, but the disease kills very few people, compared
to malaria.
Re (d) Mad Cow Disease is not caused by global climate change. It is
probably caused by cows being fed contaminated meat from diseased cows
or sheep that were infected with a disease called scrapie.
QU. 10 (10 points). We are getting towards the end of the quiz.
This question is about a concern that some scientists have about “abrupt
climate change”, which could happen as the effects of climate change
impact on each other, making things much worse. Which of the following
possibilities is not caused by global climate change?
- As the world’s temperatures increase, the tropical forests
will begin to die, releasing the carbon that is stored in them,
making things much worse.
- As more of the world’s oil supply is used up, it will
cause military and political conflict, as nations compete to control
the remaining
supplies of oil.
- As the Arctic ice melts, it will release millions of tonnes
of fresh water into the North Atlantic Ocean, diluting the salt
water. This will
cause the warm Atlantic current known as the Gulf Stream to slow
down and then switch off, plunging northern Europe into a possible
ice age.
- As the tundra thaws, it will release the vast quantities of
carbon and methane that have been stored there for hundreds of
thousands of
years, adding yet more to the world’s burden of greenhouse
gases.
Answer: (b). Burning oil releases CO2, and causes climate change,
but conflicts over the world’s oil fields are not related to
global climate change.
Re (a). Scientists at the Hadley Centre for Climate Research in England
are concerned that the Amazon forest will start to dry out around 2040,
releasing billions of tonnes of carbon, instead of storing it.
Re (c). This is a growing concern as the Arctic ice thins, and the
Greenland icecap begins to melt. There is already evidence that the
Gulf Stream
is beginning to slow. The Gulf Stream is part of the world’s thermohaline
current (thermohaline means ‘warm and salty’), which is driven
by the high salt content of water off Iceland. The salty water is heavier
than fresh water, so it sinks to the bottom of the ocean, setting the
thermohaline current in motion. The water off Iceland is saltier, because
the Arctic sea ice locks up so much fresh water. As the ice melts, it
is diluting the salty water, leading to the concern that the whole global
current could stop – as it has been known to do in the past.
For an illustration of the current, see www.grida.no/climate/vital/32.htm
Re (d). This is already happening, but the area of tundra over which
the thawing is happening is so large that nobody has been able to gather
reliable statistics.
QU. 11 (10 points). Given what you have just learnt, what do you think
is the best response to all this?
- We should get out into the streets, and on television, and
start protesting, to make people wake up and do something.
- There should be much more research, so that we have a better
understanding of what is happening.
- We should become more politically involved, so that our governments
become more active in seeking a lasting solution.
- We should keep on partying, because no-one’s going to
do anything about all this, and nobody’s going to listen to
us.
After both teams have decided, there is a full class discussion, at
the end of which, everyone votes on the 4 options. The team that chose
the response that wins the most votes wins the points. If both teams
have the same answer, they get 5 points each. Everyone in the class who
voted for the most popular answer wins 5 points.
The Winning Team receives a big round of applause, and the teams join
the rest of the class.
Round 3: Global Solutions to Climate Change
QU. 1 (10 points). Which of the following nations produces the most
CO2 per person?
- Canada
- Russia
- USA
- China
Answer: (c) USA – 20 tonnes per person. Canada is next with
19 tonnes per person
QU. 2 This is a question about SOLAR ENERGY. It comes in two
parts, each worth 5 points. Solar energy is generated by the use of
photovoltaic
cells, which capture the sun’s light and turn it into electricity.
By putting a solar panel on your roof, you can generate clean, renewable
electricity.
QU. 2A (5 points). Which of the following breakthroughs will allow the
world to benefit from the use of solar energy on a widespread scale?
- Improvements in the efficiency of photovoltaic cells, so
that they generate more energy.
- Government policies that require the use of solar energy
on all government and other buildings.
- Mass production – so that the cost of solar energy falls,
and people can afford it.
- The use of photovoltaic cells made from water, etched with
a crystalline surface
Answer: (c) As soon as one factory has enough demand to manufacture
500 MW of solar PV cells a year, the price will start to fall dramatically.
The Japanese company Sharp plans to open a 500 MW factory in 2005.
Improvements in the efficiency of photovoltaic cells (a) are important,
but they are very small, and gradual. This could change, of course,
if there was a major breakthrough.
Government policies (b) are also important, but they will not cause
the breakthrough on their own.
Photovoltaic cells made from water (d) is a nonsense idea.
QU. 2B (5 points). How large an area of land would you need
to cover with photovoltaic cells if you wanted to generate enough
electricity
to supply Canada with all the electricity it needs?
- The whole of Alberta, Saskatchewan and Manitoba
- One eightieth of Manitoba
- Half of Alberta
- All of Saskatchewan
Answer: (b) One eightieth of Manitoba
This correct answer is quite astonishing. Well-researched data
has shown that the electricity needs of the entire US electric grid
could
be
met from an area that is 100 miles by 100 miles (10,000 sq. miles),
if it were covered in solar PV cells. Canada’s population is
1/10th America’s, so the equivalent is 1,000 square miles. Solar
exposure in Manitoba is weaker, so the number has been trebled to 3,000
square miles. Manitoba is 251,000 square miles, so 3000 square miles
is 1.25% (1/80th) of the land area. No one is suggesting we do this – it
is just a theoretical calculation. It is much more sensible to place
the solar panels on roofs, above parking lots, etc.
QU. 3 This is a question is about WIND ENERGY. It comes in
3 parts, each worth 5 points.
QU. 3A (5 points). How much does wind energy cost to produce?
- 5 cents a kilowatt-hour – the same as hydroelectric
or coal-fired power
- 7 cents a kilowatt-hour – more than hydroelectric
power
- 9 cents a kilowatt-hour – the same as gas-generated
power
- 21 cents a kilowatt-hour – the same as nuclear power
Answer: (b) 7 cents a kilowatt-hour – more
than hydroelectric power
QU. 3B (5 points). In Europe, how much electricity could be
generated from wind turbines placed in the southern North Sea, where
it is relatively
easy to build them?
- Half of all the electricity that Germany needs
- Twice as much electricity as Germany needs
- Three times more electricity than Germany and Denmark need
together
- Three times more electricity than Germany, Denmark, Holland,
Belgium and Britain need together
Answer: (d) This is astonishing, but true. The
2001 report which produced this data, “North Sea Offshore Wind: A
European Powerhouse,” was
prepared by the German Wind Energy Institute.
QU. 3C (5 points). How fast is the global production of wind
energy increasing each year?
- 5%
- 17%
- 26%
- 35%
Answer: (d) 35%. By the end of 2002, the global production of electricity
from wind turbines was 31,000 MW. For a photo of the two wind turbines

QU. 4 (5 points). This is a question is about energy efficiency
- making our homes, cars, appliances, & factories more efficient,
so that they use less power. If everything we used were twice as efficient,
how
much electricity would we need to generate?
- The same amount as we do today
- Twice as much as we do today
- Four times as much as we do today
- Half as much as we do today
Answer: (b) Twice as much as we do today. This is a trick question,
to make sure they’re thinking.
QU. 5 This is a question is about TRANSPORT. It comes in 2
parts, each worth 5 points.
QU. 5A (5 points). This is about the oil that we use to fuel
our cars, trucks, buses, and airplanes. The amount of oil that is available
to
us was laid down millions of years ago, so as we use it up, there is
less left in the ground. The term “the oil peak” is used
to describe the time when the total quantity of oil produced in a year
starts to fall. How soon will this occur?
- It has already happened
- Sometime between 2005 and 2020
- Sometime between 2020 and 2050
- Sometime after 2050
Answer: (b) Sometime between 2005 and 2020
Some private energy analysts say that it will occur in 2005; the US
Energy Information Administration says it will occur in 2020. The
correct
date may be anywhere in-between.
QU. 5B (5 points). Which of these is the quickest and easiest way for
the world to use less oil, and reduce the greenhouse emissions that come
from burning oil?
- Build cars and trucks that are twice as efficient
- Build cars and trucks that run on hydrogen
- Build cars and trucks that run on electricity
- Build cars and trucks that run on natural gas
Answer: (a) Build cars and trucks that are twice as efficient. This
could be done today.
Re (b): The infrastructure is not ready for the mass production or distribution
of hydrogen. If the hydrogen is made from fossil fuels, it will still
release CO2.
Re: (c) No-one has solved the problem that batteries only offer power
for a limited distance.
Re: (d) Natural gas is still a fossil fuel, which releases greenhouse
gas emissions.
QU. 6 (10 points). This is a question about FARMING. In North America,
farming is responsible for 8% of the greenhouse gases that cause global
warming. Which of these changed farming practices would lead to the greatest
reduction in greenhouse gases?
- Changing to organic farming, or using less nitrogen fertilizer,
since the mis-use and overuse of nitrogen fertilizer causes
the release of
nitrous oxide, which is a powerful greenhouse gas.
- Farming more fruits and vegetables, instead of beef and dairy,
since cows release large amounts of methane gas from their
stomachs, through
constant belching.
- Collecting all the liquid manure that is produced in the big
hog farms, so that the methane gas, which the hog manure
produces, can
be captured, and used to generate energy.
- Changing the ways the farmers manage their land, so that the
topsoil (which stores huge quantities of carbon) is not
blown away when they
plough it.
Answer: (a) Changing to organic farming. The release of nitrous oxides
from farming releases 8.2 million tonnes of CO2 per year.
Re: (b) Methane from cattle farming releases 4.9 million tonnes of CO2
per year in Canada.
Re: (c) Methane from liquid manure releases 1.4 million tonnes of CO2
per year in Canada.
Re: (d) The loss of topsoil through poor farming methods releases 0.3
million tonnes of CO2 per year in Canada.
QU. 7 this is a question about GLOBAL GREENHOUSE GASES. It comes in
3 parts, each worth 5 points.
QU. 7A (5 points). What is the name of the global treaty that many nations
have signed, in which they agree to reduce their greenhouse gas emissions
by 5% below the 1990 level by 2012?
- The Montreal Protocol
- The Geneva Convention
- The Kyoto Protocol
- The Houston Agreement
Answer: (c) The Kyoto Protocol, signed in Kyoto, Japan, in 1997. It
still needs Russia to ratify it, before it takes full effect.
The Montreal Protocol is the treaty that is protecting the ozone layer.
The Geneva Convention is the treaty that addresses war crimes, and the
treatment of prisoners of war.
The Houston Agreement – there is no such agreement.
QU. 7B (5 points). During the negotiations for the Kyoto treaty, which
two countries tried constantly to sabotage and undermine it?
- Iran and Iraq
- The USA and Canada
- Saudi Arabia and Kuwait
- Japan and Indonesia
Answer: (c) Saudi Arabia and Kuwait. Delegates from these countries
were helped by a US lobbyist for the oil industry, and tried to delay,
obstruct and sabotage the treaty at every stage.
QU. 7C (5 points). How large a reduction in greenhouse gas emissions
do the world’s climate scientists say is needed, in order to prevent
global warming from running out of control?
- 15%
- 30%
- 45%
- 60%
Answer: (d) 60%. When all factors are taken into account, the Kyoto
Treaty will produce a 2% reduction in emissions below the 1990
level (10% below today’s level). The challenge of moving to
an energy system that is not based on fossil fuels is enormous, and
exciting.
QU. 8 (10 points). This is a question about NUCLEAR POWER. Some people
say we should build more nuclear power plants, since nuclear power does
not generate much greenhouse gas emissions. Others disagree, because
nuclear power plants produce wastes that remain radioactive for a long
time, and there is no safe way to dispose of them. How long do some nuclear
wastes remain radioactive for?
- 100 years
- 1,000 years
- 50,000 years
- Over 100,000 years
Answer: (d) Over 100,000 years. See http://www.emnrd.state.nm.us/wipp/radprimer.htm.
What was happening on the Earth 100,000 years ago?
What were humans doing? (We were still living in Africa).
QU. 9 (10 points). There are several other ideas that are being explored,
as a way to reduce our greenhouse gas emissions, and slow global warming.
Which one of the following ideas is being considered seriously, with
big investments?
- Producing energy from large solar power stations in space,
which beam energy down to Earth.
- Producing energy from anti-matter engines, which generate
energy when matter and anti-matter collide.
- Producing energy by burning “clean” coal, which
produces no CO2 emissions.
- Producing energy through cold fusion – the process by
which atomic nuclei fuse together to produce a single nucleus (in
contrast to nuclear fission, where the nucleus breaks apart).
Answer: (c) Billions of dollars are being spent by the US and Canadian
governments to help the coal industry create “clean” coal.
The escaping CO2 emissions are captured at the power plants where the
coal is burnt, and then stored away underground. It is possible, but
it will probably be very expensive.
Re (a) Solar stations in space is a wild idea that is being promoted
by a few individuals.
Re (b) NASA is working on anti-matter engines, but no one is expecting
a breakthrough, except in StarTrek, where anti-matter powers the Starship
Enterprise.
Re (d) Cold fusion has been tried, but nobody has been able to make it
work.
QU. 10 (10 points). This question is different. Instead of being scored
by whether your answer is correct or not, each team will be scored by
the response you get from the rest of the class. Each team should consider
the question for three minutes, and then choose someone to answer it.
After both people have given their answer, the Quizmaster will ask the
class which answer they like the best. The class can respond by clapping
and cheering (in which case the team which earns the most noise wins),
or by a show of hands (in case the noise will disturb other classes).
While the teams are thinking, everyone else in the class should form
into groups of three, and think what their answers are, too.
Living in Canada’s North, some people argue that there is little
we can to influence what’s happening in the world, since there
are so few people, and all the big decisions are made in Ottawa, Washington,
or Beijing.
What do you think people living in the North should do, if we want to
try to stop global warming, and prevent the Arctic from melting?
There is no correct answer to this. It is a matter of opinion. As
author of this Lesson Plan, my personal opinion is that northern communities
need to kick up stink, and take their concerns on the road, so that
the
rest of the world wakes up. The Arctic is melting – very fast.
The Winning Team receives a big round of applause, and the teams join
the rest of the class.
Round 4: Local Solutions to Climate Change
QU. 1 (10 points). How many tonnes of greenhouse gases will a typical
community of 5,000 people living in the north produce in a year?
- 25,000 tonnes
- 50,000 tonnes
- 80,000 tonnes
- 100,000 tonnes
Answer: (d) 100,000 tonnes. The Canadian average is 19 tonnes of CO2
per person, the second highest in the world, after America (20 tonnes).
QU. 2 (10 points.) How much energy could a community save, if all of
its houses and buildings were made really energy efficient, using good
insulation, and the very best windows?
- 5%–15%
- 16%–25%
- 26%–50%
- More than 50%
Answer: (d) More than 50%. If you have really thick insulation in the
roof, walls and basement, seal up all the gaps, install triple-glazed
windows, and switch over to the most efficient fridges, washers, dryers,
and lightbulbs, a 50% or more saving in energy is possible.
QU. 3 (10 points). People often talk about wind turbines being a possible
solution, and a way to generate clean, renewable power. What is the biggest
problem with wind turbines in the north?
- There’s not enough wind for them to make any commercial
sense.
- Chunks of ice fly off the blades when it gets really cold,
which can be dangerous.
- They will kill the migrating birds, in the summer.
- Many people think it’s easier to go on burning diesel,
because it is totally reliable.
Answer: (d) Resistance by local utility managers
is the main reason why there are not more wind turbines in Canada’s
north. Three 50-kilowatt turbines were built in the Arctic tundra near
Kotzebue, Alaska, in 1997,
and at least 80 remote villages in northern and western Alaska are
thought to have sufficient wind to make wind turbines viable for production.
Some wind turbines in Alaska produce more than their maximum rated
power
output because air becomes denser at lower temperatures. This effect
can cause a 20% increase in maximum power output at -37°C.
Re (a): Wind costs 7 cents kW.h (more for remote communities), and once
the turbines have been installed, there are no shipping costs, as there
are for diesel. The price of wind energy remains fixed, unlike the price
of diesel, which will rise as soon as global oil shortages begin.
Re (b): Chunks of ice flying off is a problem, but not the biggest problem.
The team that is behind the two turbines in Whitehorse are doing research
to find a non-stick surface for the blades,.
Re (c): The large new turbines turn very slowly, and have little or no
effect on birds. It is the older, smaller wind turbines, which spin very
fast and kill birds.
QU. 4 (10 points) This question is about TRANSPORT, and the way we get
around. It has 3 parts. Each part wins 5 points:
QU. 4A (5 points). Which of the following means of transport produces
the fewest greenhouse gas emissions, per person?
- Cycling
- Riding a bus that is full
- Riding a bus that is almost empty
- Driving a hybrid, gas-electric car
Answer: (a) Cycling. Buses and hybrid cars still burn gasoline or diesel.
QU. 4B (5 points). Which of these cars produces the fewest greenhouse
gas emissions?
- A Honda Civic with a gas-electric hybrid drive
- An electric car, which is charged using electricity produced
by burning diesel or natural gas
- A Volkswagen Beetle diesel car
- An electric car, that is charged using electricity produced
by solar or wind power
Answer: (d) An electric car powered by solar or wind produces no greenhouse
gas emissions at all, except during manufacture. The Honda Civic hybrid
comes next, then the Beetle, and then the electric car in (b)
QU. 4C (5 points). Which kind of snowmobile engine produces the fewest
greenhouse gas emissions?
- A diesel or biodiesel engine.
- A 4-stroke gasoline engine.
- A 2-stroke gasoline engine with fuel injection and a catalytic
converter.
- An electric engine, charged using electricity from solar
or wind energy.
Answer: (d) Electric snowmobiles do exist, so they could in theory be
charged up with power from solar or wind energy.
A 4-stroke gasoline engine is more efficient than a 2-stroke gasoline
engine with fuel injection and a catalytic converter. There are no diesel
snowmobiles. If there were, they could be fuelled with biodiesel, which
would also produce no greenhouse gas emissions.

QU. 5 (10 points). This is a question about diesel, which is used in
many communities to generate power. Which of these four statements is
correct?
- Diesel is not a fossil fuel, because when Rudolf Diesel invented
the diesel engine in 1895, he designed it to run on peanut
oil and other vegetable oils, including hemp.
- If a truck, bus or power generator runs on diesel, it can
also run on biodiesel made from vegetable oils, or waste fat from
a restaurant.
- Diesel may be a polluting fuel that produces carbon dioxide,
but at least it will never run out.
- Most communities in the North would grind to an immediate
halt without diesel, because there are no alternative fuels that
can run trucks, buses
and machinery, and generate electricity.
Answer: (b)
Re (a): The diesel that we use today is made from oil, not peanuts or
hemp.
Re (c): The world’s oil supply (which diesel comes from) will
start diminishing between 2005 and 2020.
Re (d): There are various ways to make energy that do not require the
use of fossil fuels, such as from the wind, solar, geothermal heat, biomass,
biodiesel, and with hydrogen fuel cells.
QU. 6 (10 points). This is a question about tidal energy – the
idea that you can generate energy from the power in the ocean’s
tides, as the water flows back and forth. Which of these four statements
is correct?
- Tidal energy is a good idea, but nobody has been able to make
it work yet.
- Tidal energy could never work in the Arctic, because of all
the ice.
- Tidal energy is already being generated in the Arctic.
- Tidal energy in the Arctic would be a hazard to the polar
bears and seals, because of the underwater turbines.
Answer: (c) The world’s first tidal turbine was installed at Hammerskaer,
off Norway’s Arctic Coast, in 2002.
Re (a): Tidal turbines are also operating in France, and off the Devon
coast of England and in the Bay of Fundy in Canada.
Re (b): Tidal turbines run under the ice, not at the surface.
Re (d): The turbines spin very slowly, at 25 rpm, so there would not
be a danger to wildlife.
QU. 7 (10 points). This is a question about groundsource heat.
This is a system that captures the earth’s underground warmth
in pipes, and transfers it into a building using a heat pump. Which
of these four
statements is correct?
- Groundsource heat is one of those ideas that inventors think
up, but never really works
- Groundsource heat is not possible in the North, because the
ground is too cold
- Groundsource heat is more cost effective if the ground is
made from soil and sand, not rock.
- Groundsource heat requires as much energy for the pumping
as it extracts in heat.
Answer: (c) It costs more to drill into rock than it does to lay lines
in soil or sand.
Re (a): There are many ground-source heat systems operating in Manitoba,
and around the world,
Re (b): Two metres below the ground, the temperature is stable, and
warmer than the surface temperature.
Re (d): For every one unit of energy put in to run the pump, four units
of energy are returned.
See www.earthenergy.ca for a diagram that shows how ground-source energy
works.
QU. 8 (10 points). This is a question about small-scale hydro, which
is a way to generate energy from the flow of water in a river. Which
of these four statements is correct?
- Small-scale hydro is not used in the North, because rivers
and creeks are frozen throughout the winter.
- Small-scale hydro used to be done in the old days, but these
days it is more efficient to build a big dam, because it will produce
much more energy.
- Small-scale hydro is undergoing a revival in popularity, because
it is a good way to generate clean, renewable energy
- Small-scale hydro projects are environmentally harmful, because
they stop fish from migrating upstream.
Answer: (c)
Re (a): There is a small-scale hydro plant east of Whitehorse, high
up in the mountain pass on the road to Skagway. It draws water from
under
the ice.
Re (b): It is the big dams that are losing popularity since they
flood so much land. Small-scale hydro schemes cost around 5.5 cents/
kWh, and
are a very cost-effective way to generate power.
Re (d): There are careful systems to ensure that when water is diverted
from a creek or river to flow through a small-scale hydro turbine,
the fish are not disturbed.
QU. 9 (10 points). This question is called ‘thinking outside the
box.’ Which of these four statements are many scientists and engineers
seriously considering?
- In the future, people in northern communities will keep themselves
warm in winter by covering themselves entirely in huge glass
or plastic domes, to keep the cold out.
- In the future, people in northern communities will generate
the energy they need by putting giant solar collectors into space,
and beaming their
energy down to a collector next to the community.
- In the future, people in northern communities will be able
to generate the power and heat they need by burning the methane
that is locked up
in the frozen tundra, as global warming causes it to melt.
- In the future, people in northern communities will live in
homes and buildings that are so well designed and insulated that
they won’t
need any heating at all, even in the winter.
Answer: (d) There is research going on into super-efficient homes all
over the world. It is possible that in a super-efficient home, the heat
from our own bodies could keep us warm, even in winter.
Re (a): No-one is suggesting that northern communities should cover themselves
with glass or plastic domes. Maybe they should?
Re (b): There is a small band of “solar beam” engineers who
think it’s a great idea, but few people are taking the idea seriously.
The cost would be enormous, and so would the difficulties of repairing
damage from space debris, and the danger if the solar beam was knocked
off course.
Re (c): The escaping methane is spread around over such a wide area
that it is impossible to collect. There are engineers who want to mine
the
oceans for methane hydrates – giant chunks of frozen methane gas,
that sit on the ocean floor – but many people find the idea alarming,
since methane is a very powerful greenhouse gas.
QU. 10 (10 points) This point is different. Instead of being scored
by whether your answer is correct or not, each team will be scored by
the response it gets from the rest of the class. Discuss the question
the question for two minutes, and then choose someone to answer it.
After both teams have given their answer, the Quizmaster will ask the
class which answer they liked the best. The class can respond by clapping
and cheering (in which case the team which earns the most noise wins),
or by a show of hands.
The threat to the Arctic from global climate change is so
serious that the only rational response by people who live in the
north is to
become political, and lobby people in other countries to stop producing
greenhouse gases.” Do you agree or disagree with this statement,
and if so, why?
This is all good food for discussion.
The Winning Team receives a big round of applause, and the teams join
the rest of the class.
Round 5: Personal Solutions to Climate Change
QU. 1 (10 points). How much greenhouse gas does the average Canadian
produce in a year from driving, heating the home, using electricity,
and flying, etc?
- (a) 1 tonne
- (b) 5 tonnes
- (c) 19 tonnes
- (d) 32 tonnes
Answer: (b) 5 tonnes of CO2.
QU. 2 This question is about Driving. It comes in 4 parts, each of which
is worth 5 points.
QU. 2A (5 points). How many kilograms of carbon dioxide does a car produce
for each litre of gasoline it burns?
- 0.025 kg
- 0.25 kg
- 2.5 kg
- 25 kg
Answer: (c) 2.5 kg
QU. 2B (5 points). How is it possible that the carbon dioxide that is
released by burning a litre of gasoline weighs more than the gasoline
itself?
- The CO2 is heavier because the carbon from the gasoline gets
mixed up with oxygen from the atmosphere.
- The CO2 is heavier because it mixes with gravity when it
is released from the gasoline.
- The CO2 is heavier because the energy that was used to drive
the car becomes mixed up with the car’s exhaust fumes.
- The CO2 is
heavier because all greenhouse gases are heavy – that’s
why they get trapped in the atmosphere.
Answer: (a). As soon as a molecule of carbon (C) is released from the
fuel, it mixes with two molecules of oxygen (O). One kilo of carbon becomes
3.667 kilos of CO2.
(b). (c) and (d) are all mixed up thinking.
QU. 2C (5 points). Listen up very carefully. This is not a trick question.
Now you know how many kilograms of carbon dioxide a car produces for
each litre of gasoline (2.5 kg). If a car burns 8 litres of gasoline
for every 100 km it travels, how many kilograms of carbon dioxide will
it produce during a year, if the owner drives 15,000 km?
- 800 kg
- 1,200 kg
- 3,000 kg
- 1,500 kg
Answer: (c) 3000 kg. If you drive 15,000 km in
a car that burns 8 litres per 100 km, you’ll burn 1200 litres
of gas. Each litre releases 2.5 kg of CO2, so the correct answer
is 3,000
kg, or 3 tonnes.
QU. 2D (5 points). Here are four ways that will reduce the greenhouse
gas emissions that a vehicle produces. I want you to place them in order,
with the method that causes the greatest reduction in emissions listed
first.
- Turn the engine off instead of idling, if you are waiting for
someone, or at the traffic lights.
- Switch to a more fuel-efficient vehicle.
- Stop driving – switch to walking, cycling or taking the
bus instead.
- Check your tire pressure, and make sure your car is well
serviced.
Answer: The correct order is:
c. Stop driving.
b. Switch to a more fuel-efficient vehicle.
a. Turn the engine off
instead of idling.
d. Check your tire pressure, and make sure your
car is well serviced.
QU. 3 (10 points). This question is about walking and cycling.
Which of the following excuses do you think is the most pathetic reason
for
not walking or cycling to the shops, to school, or to see a friend, when
it’s not snowing?
- It will take me too long.
- It’s too cold.
- Why bother, if someone in my family, or a neighbour, is willing
to drive me?
- My mum says it’s dangerous – someone might attack
me.
After the teams have made their choice, everyone the class will vote
on which of the four excuses they think is the most pathetic. The team
whose answer matches the class’s answer wins the points. If both
teams have the same answer, they get 5 points each. Everyone in the class
who voted for the “winning’ excuse wins 5 points.
This is all food for discussion
QU. 4 This question is about Recycling. It comes in 4 parts, each of
which is worth 5 points.
QU. 4A (5 points). When trees are left standing, they gather and store
carbon from the atmosphere. If you use paper that is made from 100% post-consumer
recycled paper instead of trees, how many trees will be left standing
for each tonne of paper that you use?
- 2
- 8
- 17
- 29
Answer: (c) 17.
QU. 4B (5 points). When aluminum is made, a lot of energy is used, and
producing the energy usually produces a lot of greenhouse gas emissions.
When you recycle an aluminum can, how much energy can be saved by making
new cans from the recycled aluminum?
- 18%
- 36%
- 72%
- 95%
Answer: (d) 95%
QU. 4C (5 points). When steel is made, a lot of energy is also used
(but nowhere near as much as aluminum). When you recycle a steel can,
how much energy can be saved by making new cans from recycled steel?
- 15%
- 34%
- 61%
- 88%
Answer: (c) 61%
QU. 4D (5 points). When plastic is made, a lot of energy is used. When
you recycle your hard plastic containers, how much energy can be saved
by making new plastic products from recycled plastic?
- 8%
- 33%
- 79%
- 94%
Answer: (b) 33%
QU. 5 (10 points) Airplanes burn kerosene, which is a fossil fuel, so
they release CO2 when they fly. If you fly from Whitehorse to Vancouver,
or from Yellowknife to Calgary, how much CO2 will you produce, as your
personal share of the flight?
- 50 kg
- 357 kg
- 850 kg
- 1200 kg
Answer: (d) 1200 kg (1.2 tonnes). You can find out
what your CO2 emissions are for any flight by going to http://www.chooseclimate.org/flying/ and
marking your origin and your destination.
QU. 6 This is a question about the appliances we use in our homes. It
come in 3 parts, each of which is worth 5 points. All appliances use
power, and if that power comes from diesel oil, natural gas or coal,
it will release greenhouse gas emissions.
QU. 6A (5 points). Which of these appliances uses the most power, over
the course of a year?
- A water heater
- A fridge
- A microwave
- A dryer
Answer: (a) A water heater
QU. 6B (5 points). Pay careful attention. This question needs
some math. If electricity costs 6 cents for each kilowatt hour, and
an old fridge
uses 1200 kW.h of electricity a year, how much money will you save in
a year if you replace it with a fridge that only uses 520 kW.h a year?
(Teachers – you should adjust the cost, and the answer, based on
the actual local cost.)
- $10
- $20
- $40
- $80
Answer: (c) $41. 1200 kW.h at 6 cents comes to $72. 520 kW.h at 6 cents
comes to $31. The saving is $41 a year, so $40 wins.
QU. 6C (5 points). How many different types of appliance or device can
you think of that use electricity in an average home? You have 2 minutes.
After 2 minutes, each team in turn calls out one appliance or device.
The Quizmaster writes down the appliances that each team thinks of
on the blackboard, and the team with the most wins. Any student whose
total
comes close also wins the 5 points.
QU. 7. This question is about the way we heat our homes. It comes in
two parts, each of which is worth 5 points.
QU. 7A (5 points). What is the cheapest way to keep warm in a house,
while using less fuel or electric power?
- Add extra insulation to the roof
- Put on a warmer sweater and turn down the thermostat
- Seal up all the gaps and cracks with caulking
- Upgrade your boiler, or heating system.
Answer: (b) Put on a warmer sweater and turn down the thermostat
QU. 7B (5 points). Which of these things can you do yourself to make
your home warmer, without much difficulty?
- Replace all your windows with tighter, more efficient windows
- Seal up all the gaps and cracks with caulking
- Upgrade your boiler, or heating system.
- Add extra insulation to the roof
Answer: (b) Seal up all the gaps and cracks with caulking
QU. 8 (10 points). If you eat beef, the cows that the beef came from
will have produced methane gas, which is a powerful greenhouse gas. Which
of these statements is true?
- All animals produce a lot of methane gas, so it doesn’t
really matter
- If you become a vegetarian, you will also produce a lot of
methane gas, so it won’t make any difference if you eat less
meat.
- A typical family of beef eaters will be responsible for 1.3
tonnes of greenhouse gases from the methane from the cows that
produced their
beef in a year.
- If you feed the cows “Beano”, it will stop the
methane gas.
Answer: (c)
Re: (a) It is cows that have four stomachs, and produce so much gas.
Re (b) Amusing, but false. Humans only have one stomach. And do meat-eaters
never fart?
Re (d) Amusing, and partly true, but not enough to win the points.
Scientists in Scotland are working to develop a special enzyme
to feed to cows that
might reduce the amount of methane that they produce.
QU. 9 We’re getting close to the end now. This is a question about
the “stuff” that a typical North American family consumes
in a year. It comes in 3 parts, each worth 5 points.
QU. 9A (5 points). Think about all the things that a typical
North American buys and uses during a year. Now think about everything
that is needed
to gather the raw materials, make them, and ship them around. Now here’s
the question. When you add up all of the stone, cement, coal, minerals,
oil, gas, wood, grass, and metals that are needed to do all this, how
many tonnes of material do you think a typical North American uses in
a year?
- 2 tonnes
- 20 tonnes
- 13 tonnes
- 28 tonnes
Answer: (b) 20 tonnes
QU. 9B (5 points). If everyone who lives on the Earth consumed the same
amount of stuff that North Americans do, how long would it be before
we ran out of the materials needed to make them?
- 50 years
- Never
- 350 years
- Yesterday
Answer: (d) Yesterday. “Ecological footprint” analysis
shows that if everyone were to consume at the same rate that North
Americans
do, we would need 1.5 planets.
QU. 9C (5 points). Which of the following do you think is the most sensible
way to make a smaller impact on the Earth, with all the stuff we consume?
(After the teams have decided, everyone will vote on each of the 4 options.
The team that chose the response that wins the most votes wins the points.
If both teams have the same answer, they get 5 points each. Everyone
in the class who voted for the most popular answer wins 5 points.)
- Try to buy everything using recycled materials
- Stop consuming so much stuff, and live more simply
- Don’t worry about it. Humans have always been creative,
so modern technology will find a substitute as soon as something
runs out.
- Persuade your parents to sell everything you don’t
really need as a family, and use the money to help you get a training
or education so that you can do something that will make a difference.
This is all good food for discussion.
QU. 10 (10 points) The final question is about activism. It
follows the words of the American anthropologist, Margaret Mead, who
once said: “Never
doubt that a small group of thoughtful, committed citizens can change
the world. Indeed, it’s the only thing that ever has.”
Which of the following statements do you think is a sensible response
to the threat of global climate change in the Arctic?
(After both teams have decided, there is a full class discussion, at
the end of which, everyone votes on the 4 options. The team that chose
the response that wins the most votes wins the points. If both teams
have
the same answer, they get 5 points each. Everyone in the class who voted
for the most popular answer wins 5 points.)
- All young people should write to the Prime Minister of Canada,
and the Premiers of the Yukon, NWT and Nunavut, asking them to take
more
actions to protect the world, and especially the Arctic, from global
climate change.
- We should do something more dramatic that will win people’s
attention, like fasting for a week, or holding a sit-in on the
ice, before it melts in the summer.
- These are stupid ideas. We should put our attention into getting
a good education, so that we can learn how to develop and use
the new technologies that don’t depend on fossil fuels.
- It’s all too late, and nobody cares what’s happening
up here in the North. Besides we’re too few to make a difference.
We may as well just get on with life, and enjoy it while we can.
This is all good food for discussion.
The Winning Team receives a big round of applause, and the teams join
the rest of the class. |
