• Boreal Forest

• Fishing ecosystem

• Tributary system

• Salmon population

In order for land to be used for industrial, commercial, and agricultural purposes, many of Canada's _________________ have been drained.

• Lakes

• Rivers

• Forestland

• Wetlands

The continued extraction of natural resources --- particularly coal, oil, and natural gas from the tar sands in Alberta --- fuels a growing concern among many people about

• Wetlands

• Climate Change

• The fishing industry

• Old-growth forests

___________________ is believed to contribute directly to climate change and the rising of the Earth's temperatures.

• Logging

• Carbon Dioxide

• Overfishing

Protection of _____________________ is an example of how Canada is taking steps to protect its renewable resources.

• Pacific Salmon

• Trees producing sap for maple syrup

• Nagara Falls

• Deep sea drilling areas

Which of the following is a result of extracting natural resources?

• An increased water supply

• A replenished timber supply

• A shrinking boreal forest

• A reduction in greenhouse gases

How are old-growth forests and wetlands similar?

• They both contain sacred ground for indigenous communities

• They provide valuable carbon dioxide

• They have been overdeveloped for the tourism industry

• They are increasingly rare and need to be protected

Why is Canada's boreal forest important to the environment?

• It provides a valuable water supply to native populations

• It keeps carbon dioxide from entering the atmosphere

• It provides a barrier from acid rain pollution

• Its seedling development lowers the amount of dead maple leaves

Which of the following is a result of overfishing?

• A diminished fish supply

• A replenished fish supply

• An overpopulation of Pacific Salmon

• An economic benefit to Canada's fishing industry

Which of the following explains the impact of hydroelectricity?

• Its high cost makes drinking water expensive

• If often requires damming, which impacts ecosystems

• Its production releases carbon dioxide into the air

• It causes acid rain, threatening nearby plant life
