Final answer:
Environment Canada was established in 1971, within the context of a heightened global awareness of environmental challenges, paralleled by the earlier creation of the EPA in the United States in 1970.
Step-by-step explanation:
Environment Canada, which plays a vital role in environmental protection and policy, was created in the year 1971. This organization came into existence during a period when environmental issues were gaining prominence on a global scale, as reflected by other international movements and regulations such as the discovery of the ozone hole, the formation of the Intergovernmental Panel on Climate Change, and the Earth Summit in Rio de Janeiro.
In parallel, the United States witnessed the creation of the Environmental Protection Agency (EPA) in 1970, previously established to help address environmental challenges and to oversee environmental laws.
