Environmental and ecological conservation in Perryville is a political, environmental and social movement that seeks to protect natural resources including plant and animal species as well as their habitat for the future. Contemporary conservation movement has broadened from the early movement's emphasis on use of sustainable yield of natural resources and preservation of wilderness areas to include preservation of biodiversity. It is part of the broader and more far-reaching environmental movement. Conservation aims to preserve natural resources expressly for their continued sustainable use by humans. Conservation is also used more broadly to include the setting aside of natural areas and the active protection of wildlife for their inherent value, as much as for any value they may have for humans.
