Endangered Species Act Passed: Wildlife Protected

The bald eagle was nearly gone. The grizzly bear, the Florida panther, the California condor — all circling extinction. On December 28, 1973, Nixon signed a law that didn't just list threatened animals but gave them teeth: federal agencies had to stop projects that would wipe out species, even if it meant halting dams mid-construction. The timber industry howled. Developers sued. But the Act worked. Today, the bald eagle thrives, delisted in 2007. The catch? It protects bugs and plants too, not just charismatic mammals — and that's where the real fights happen.
