11. Fill in the missing way of increasing greenhouse gases by picking a word from the word box and matching it to
its description.
Deforestation
Land travel

Oil sands
Coal-fired Power Plants

Industry and Manufacturing
Hydroelectric Dams
Agriculture
Air Travel
- these generate greenhouse gases, especially carbon dioxide
- can also be a high source of methane with flooding of land to build the dams causes large
volumes of standing water
- means less carbon dioxide is removed from the air by photosynthesis
- this process involves clearing of land and trees, building of more roads and increased
transportation
- construction companies clear hundreds of trees daily to make way for these
- this means that there will be increased fossil fuels being burned by cars, producing carbon
dioxide and nitrous oxides
- this burns up very large amounts of fossil fuel and is the fastest growing source of greenhouse
gas emission globally
- occurring in Alberta, this is the fastest-growing source of greenhouse gases in Canada – it
generates three times as much greenhouse gas as producing one barrel of conventional oil
- these generate large amounts of methane gas
- fertilizers cause an increase in nitrogen in our soil increasing nitrous oxides
- raising crops and livestock all contribute to increased greenhouse gases
- Since Canada is one of the coldest countries and we generate a great deal of greenhouse gases
with this
- majority of the electrical energy produced in the Maritimes and the Prairies comes from this
- this occurs in centres in southern Ontario as they produce carbon dioxide, methane, nitrous
oxide and halocarbons (CFC’s) in various production processes
