Exercise 13
Result
1 of 1
The grass will act as a carbon sink to reduce the amount of carbon dioxide in the area. The production of oxygen also reduces the overall concentration of greenhouse gas in the environment
Exercise 14
Result
1 of 1
As the population increases, more people will be using resources so human activity will have an even greater impact on climate change
Exercise 15
Result
1 of 1
The burning of fossil fuels releases greenhouse gases, which raise temperatures. The increase in temperatures causes ice to melt, which raises sea level
Exercise 16
Result
1 of 1
Nations that can afford to adopt sustainable practices and cut back on emissions should. This will pave the way for cheaper solutions to be found which can be implemented in developing nations since they cannot make the change as easily if their small economy thrives off of a practice that is not sustainable
Exercise 17
Result
1 of 1
These changes will be a problem for Canada. Since the climate is changing, industries may no longer have success in certain areas that rely on the climate. The loss of animal habitats may ruin traditional food sources
Exercise 18

Where are your ingredients primarily sourced from?

Do you compost or recycle food scraps?

How is the energy efficiency of the restaurant?

Exercise 19
Result
1 of 1
Since the climate changed, plant life and insect life could be effected in the region, which would limit the bird’s food supply. This could be tested by comparing the climate to the change in amount of available food to the song bird.
Exercise 20
Result
1 of 1
Trees act as carbon sinks. They utilize carbon dioxide in the atmosphere to produce food and oxygen for other organisms within their ecosystem.
Exercise 21
Step 1
1 of 3
a) the glaciers will melt and become smaller in size due to climate change.
Step 2
2 of 3
b) The melting of these glaciers will lower the Earth’s albedo, increasing temperatures. Also, water levels will rise

a) the glaciers will melt and become smaller in size due to climate change.
Exercise 22
Result
1 of 1
The heat capacities of ice and water, and the amounts of ice and water
Exercise 23
Result
1 of 1
I drive my car around town and heat my house. If I took a bus or rode a bike I could lower my emissions. If i turned heat off in rooms I do not use I could lower emissions.
Exercise 24
Result
1 of 1
People can drive electric cars, purchase solar panels, and eat less meat to reduce emissions. By not relying on gasoline as much in our homes and cars, emissions are reduced, and by eating less meat, the processes that produce the meat and emissions will receive less business and may go out of business.
Exercise 25
Result
1 of 1
The role of the IPCC is to assess scientific information that links human activity to climate change sand aims to lessen the human activities that cause it
