Aspects of the law that safeguard the environment are collectively referred to as environmental law. The management of certain natural resources, such as forests, minerals, or fisheries, is the subject of a related but different set of regulatory regimes that are now heavily impacted by environmental legal principles. The Clean Air Act, the Endangered Species Act, the Montreal Protocol, the Clean Water Act, and Reformation Plan No. 3 of 1970 are our five most effective environmental laws. These regulations have had a significant positive impact on both the environment and the health of Americans.
