Environmental protection is an increasing concern of individuals, organisations and governments.
Due to the pressures of population and technology the biophysical environment is being degraded, sometimes permanently. This has been recognised and governments began placing restraints on activities that caused environmental degradation. Since the 1960s activism by the environmental movement has created awareness of the various environmental issues. There is not a full agreement on the extent of the environmental impact of human activity and protection measures are occasionally criticised.
Academic institutions now offer courses such as environmental studies, environmental management and environmental engineering that study the history and methods of environmental protection.
Protection of the environment is needed from various human activities. Waste, pollution, loss of biodiversity, introduction of invasive species, release of genetically modified organisms and toxics are some of the issues relating to environmental protection.
The U.S. Environmental Protection Agency (EPA or sometimes USEPA) is an agency of the federal government of the United States charged with protecting human health and with safeguarding the natural environment: air, water, and land. The EPA was proposed by President Richard Nixon and began operation on December 2, 1970, when it was passed by Congress, and signed into law by President Nixon, and has since been chiefly responsible for the environmental policy of the United States.[3] It is led by its Administrator, who is appointed by the President of the United States. The EPA is not a Cabinet agency, but the Administrator is normally given cabinet rank. The current Administrator (as of 2007) is Stephen L. Johnson, and the current Deputy Administrator is Marcus Peacock. The agency has approximately 18,000 full-time employees.
