The ESA is vital, but it operates more like an emergency room, not preventive care. By that point, species are already on life supportâand the price tag is high. The Endangered Species Act (ESA) was created in 1973 to save Americaâs most vulnerable wildlife.However, the way it works today isnât enough to protect our wildlife going forward.y that point, species are already on life supportâand the price tag is high.

Its purpose is to prevent the extinction of our most at-risk plants and animals, increase their numbers, and effect their full recovery â and, eventually, their removal from the endangered list. Currently, the Act protects more than 1,000 species in the United States. The more money is spent on a species, the more likely that species is to be recovering.
