Park
A park is a protected area, in its natural or semi-natural state or planted, and set aside for human recreation and enjoyment. It may consist of, rocks, soil, water, flora and fauna and grass areas. Wilderness parks are intact and undeveloped areas used mainly by wild species. Many parks are legally protected by law. Protected wilderness zones are required for some wild species to survive. Some protected parks focus mainly on the survival of a few threatened species, such as gorillas or chimpanzees. A national park is a reserve of land, usually, but not always declared and owned by a national government, protected from most human development and pollution. National parks are a protected area of IUCN category II. The largest national park in the world is the Northeast Greenland National Park, which was established in 1974.
