3. a district, river, forest, etc., under such supervision.

The preservationist approach wants
to preserve nature in its natural state, untouched by human development. The 1964 Wilderness act describes the larger goal of preservationists: "A wilderness, in contrast with those areas where man and his own works dominate the landscape, is hereby recognized as an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain ..."
- The Wilderness Act, September 3, 1964
Preservation:
1. to keep alive or in existence; make lasting: to preserve our liberties as free citizens.
2. to keep safe from harm or injury; protect or spare.
"Conservation" is the wise use of natural resources to benefit the greatest numbers of people, for the longest time. The term conservation was introduced in 1907 by Gifford Pinchot and W.J. McGee to embrace the collective use and preservation of forests, waters, soils, and minerals. The conservation ideal was natural resource management for the greatest good of the greatest number over the long run. The conservation movement emphasized resource development that generated jobs, affordable housing, food, safety, and health. Conservation implies sound biosphere management within given social and economic constraints, producing goods and services for humans without depleting natural ecosystem diversity, and acknowledging the naturally dynamic character of biological systems.
Two opposing viewpoints had emerged within the environmental movement by the early 20th century: the conservationists and the preservationists. The conservationists (such as Gifford Pinchot ) focused on the human management and wise use of nature, whereas the preservationists sought to protect and perserve nature from development and human use. [3] The idea of protecting nature for nature's sake began to gain more recognition in the 1930s with American writers like Aldo Leopold , calling for a "land ethic" and urging wilderness protection. It had become increasingly clear that wild spaces were disappearing rapidly and that decisive action was needed to save them.
