In the United States, responsibilities for the administration of environmental laws are divided between numerous federal and state agencies with varying, overlapping and sometimes conflicting missions. EPA is the most well-known federal agency, with jurisdiction over many of the country's national air, water and waste and hazardous substance programs. Other federal agencies, such as the U.S. Fish and Wildlife Service and National Park Service pursue primarily conservation missions, while still others, such as the United States Forest Service and the Bureau of Land Management, tend to focus more on beneficial use of natural resources.
