What is one positive effect of environmental-protection laws?

Environmental law, also considered as the environmental and natural resources law, is a collective solution to environmental pollution. An associated but different array of regulatory regimes, now strongly affected by the environmental legal values, aims at the administration of the particular natural resources like minerals, fisheries, or forests.

For example, the Marine Research, Protection, and Sanctuaries Act prevent discarding of waste in the United States ocean waters without authorization, and the Clean Air Act restricts the emissions of pollutants.
