In July the U.S. Fish and Wildlife Service announced changes to how key parts of the Endangered Species Act (ESA) will be implemented, including a new definition of what it means to “harm” an endangered species. To discuss the history of the ESA, the impact its made on at-risk wildlife and the importance of habitat preservation, Science Quickly host Rachel Feltman talks to marine biologist Lynne Barre, who recently left the National Oceanic and Atmospheric Administration after a 25-year career at the agency. They talk about the gray whale comeback that the ESA helped bring about, the earlier Supreme Court dissent that the current administration is using to define “harm” and the government workforce problem that could put animals at risk.
