註釋" Human activity and the environment is a collection of environmental statistics, brought together from many sources including Statistics Canada and other federal and provincial government departments. The publication provides a statistical picture of Canada's physical environment while placing special emphasis on human activities and their relationships to other elements of the natural system - air, water, soil, plants and animals." --
