Fifty-one years ago this May, President Richard Nixon signed into law one of the most consequential pieces of environmental legislation ever written — and he did it with overwhelming bipartisan support, 194 Democrats and 160 Republicans standing behind the Endangered Species Act. Today, on the third Friday of May, Americans observe Endangered Species Day, a moment to reflect on what this 1973 law has actually accomplished: it has prevented the extinction of more than 1,000 species across the United States.
The numbers tell a story of recovery against the odds. As of 2023, fifty-seven species have recovered so well that they've been "delisted" entirely. Another fifty-nine have improved enough to move from the dire "endangered" category to "threatened." Most strikingly, ninety-nine percent of all species ever placed on the list have not gone extinct — a success rate that speaks to the power of coordinated protection efforts.
Yet the work is far from finished. Right now, fewer than four hundred North Atlantic right whales remain in the world, gentle giants that roam the Atlantic coast facing two relentless threats: fast-moving boats and fishing gear entanglements. Since 2017, these two causes alone have killed sixty-two of these whales. Solutions exist — vessel speed reductions during critical breeding seasons and ropeless fishing technology — but implementation requires sustained commitment and investment.
One of the most innovative protection strategies emerging across the country is the construction of wildlife crossings, structures that let species safely navigate the sprawl and roads that fragment their habitats. These aren't just nice-to-haves; they work. Wildlife crossings can reduce vehicle collisions with animals by over ninety percent. In North Carolina, where only a couple of dozen red wolves remain and cars are their primary killer, the state is building a crossing along U.S. Highway 64. In Texas, at Laguna Atascosa National Wildlife Refuge, one of only two places in America where spotted ocelots still breed in the wild, new underpasses are letting these secretive wildcats cross safely. In Montana, the Confederated Kootenai and Salish Tribes secured federal funding to build a crossing over U.S. Highway 93 specifically designed for grizzly bear mothers and cubs — a direct response to road deaths that took the life of the famous Grizzly Bear 399, whom researchers had tracked for years.
These efforts reflect a deeper truth: protecting endangered species requires state and local leadership, federal support, and a willingness to reimagine our relationship with the land. State wildlife agencies carry much of the load, managing habitats and species across their territories. Colorado is using vaccines to save black-footed ferrets once thought completely extinct. Michigan has brought the Kirtland's warbler back from the edge. Minnesota is restoring prairie violets to save the fritillary butterfly. South Carolina is fighting invasive plants to protect wood storks.
What began as a bipartisan commitment in 1973 remains urgent today. The Endangered Species Act didn't just prevent extinction; it showed that when we decide a species matters, we have the tools and ingenuity to save it. The question now is whether we'll sustain that commitment for the next fifty years.
