Conservation
The definition accepted in 1969 by the United Nations and the International Union for the Conservation of Nature is “the rational use of the environment to achieve the highest quality of living for mankind.” Conservation involves an ethic of resource use, allocation, exploitation, and protection that includes as a primary focus maintaining the health of the natural world including its forests, fisheries, habitats, and biological diversity. A secondary definition of conservation relates to the efficient use and decreased consumption of resources (e.g., water, energy, minerals, etc.) while providing the same level of service.
