By conserving them, guided by the best-available science, we help protect healthy air, land, and water for everyone.
The ESA was enacted in 1973 as a response to the declining populations of many species of animals and plants. The Act was designed to protect and recover species at risk of extinction and to promote the conservation of ecosystems and habitats necessary for the survival of those species. Each of these species is a part of the web of life, each with a unique cultural and biological community, performing services that are essential to our combined well-being. By conserving them, guided by the best-available science, we help protect healthy air, land, and water for everyone.
