Many animals in Canada face the risk of extinction. Animals are put at risk for several reasons, including: climate change, the loss of forest and grassland to cities and agriculture, hunting, fishing, and the pollution of lakes and rivers. As of 2021, 554 animal species are at risk in Canada, according to the Committee on the Status of Endangered Wildlife in Canada. In addition, 18 are extirpated and 18 extinct. The committee’s definition of a wildlife species includes taxonomic categories as well as geographically distinct populations. For example, the beluga whale (Delphinapterus leucas) is included in the list of at risk animal species six times, as there are six different populations facing different threats to their survival.

A species is endangered if there are threats to its survival. Plants are put at risk for several reasons, including: climate change and the loss of natural habitat to cities, agriculture and industry. In Canada, these activities threaten entire natural ecosystems, such as older forests and Prairie grasslands. As of 2021, 250 plant species are at risk in Canada, according to the Committee on the Status of Endangered Wildlife in Canada. In addition, four are extirpated and one is extinct. The committee’s definition of a wildlife species includes taxonomic categories as well as geographically distinct populations. For example, the bent spike-rush (Eleocharis geniculate) is included on the list of at risk plant species twice, as there are two different populations, one in British Columbia and one in Ontario, facing different threats to their survival. (See also Endangered Animals in Canada.)

The term "energy" is often used interchangeably with the term "power," but incorrectly so. Energy is defined as the capacity to do work and is measured in joules (J) or watt hours (1 Wh = 3600 J).

CANADIANS ARE now committed to the reduction of greenhouse gas emissions under the Kyoto Protocol, even though Ottawa may not have a well-developed plan. But Dean Scammell does, and he's a good six years ahead of the government.

The environmental movement seeks to protect the natural world and promote sustainable living. It had its beginnings in the conservation efforts of the early 1900s. During this time, conservationists aimed to slow the rapid depletion of Canadian resources in favour of more regulated management. Many scholars divide the evolution of the environmental movement into “waves.” These waves are periods in time easily characterized by certain themes. While the number of waves and their characterization may differ from scholar to scholar, they’re often defined as follows: The first wave focused on conservation; the second, pollution; the third, the professionalization of environmental groups; and the fourth, climate change.
