An historical look back on this event by HEATHER COX RICHARDSON about what shaped this monumental act as well as how it has changed over time from her “Letters From An American” substack.
“…On December 28, 1973, President Richard Nixon signed the Endangered Species Act into law. Declaring that Congress had determined that “various species of fish, wildlife, and plants in the United States have been rendered extinct as a consequence of economic growth and development untempered by adequate concern and conservation,” the act provided for the protection of endangered species.
Just over a decade before, in 1962, ecologist Rachel Carson had published Silent Spring, documenting how pesticides designed to eliminate insects were devastating entire ecosystems of linked organisms. The realization that human destruction of the natural world could make the planet uninhabitable spurred Congress in 1970 to create the Environmental Protection Agency. And in 1973, when Nixon called for stronger laws to protect species in danger of extinction, 194 Democrats and 160 Republicans in the House—99% of those voting—voted yes. Only four Republicans in the House voted no.
Such strong congressional support for protecting the environment signaled that a new era was at hand. While President Gerald Ford, who succeeded Nixon, tended to dial back environmental protections when he could in order to promote the development of oil and gas resources, President Jimmy Carter pressed the protection of the environment when he took office in 1977.”
