Canada is not only a large country but an ecologically diverse one as well. Canada borders on three oceans, contains vast areas of boreal and temperate forest
ecosystems, mountainous ecosystems, arctic ecosystems and prairie grassland ecosystems to name a few. These ecosystems support numerous human activities
such as agriculture and forestry upon which the country’s economy heavily depends. While some activities often leave no impact and others help restore ecosystems,
generally the integrity of Canada’s ecosystems is threatened from the collective weight of many kinds of human activities originating from both within and beyond the
ecosystem borders. The science of ecosystems is relatively young but is gradually improving. Despite this situation, society is attempting to implement various
measures to conserve and protect entire ecosystems and their components so they will continue to sustain themselves and provide for future generations.
