The Endangered Species Act (ESA) turns 50 years old this year. The law, which was passed in 1973 by overwhelming bipartisan majorities in Congress (unanimous in the Senate) and signed into law by President Nixon, stands as an enduring testament that we can rise above our lesser instincts and be good stewards of what President Reagan referred to as “this magical planet that God gave us.” From the deliberate and cruel efforts to eradicate wolves and grizzly bears from the Lower 48, to the carelessness that drove the bald eagle, our national symbol, to the brink of extinction, history is full of examples where mankind has been intolerant of wildlife and/or ignorant of its needs. Thanks to the ESA, bald eagle numbers have recovered across the Lower 48, going from a low of 1,000 or less in the 1950s to more than 300,000 today. Wolves and grizzly bears have also rebounded significantly, with healthy, sustainable populations in several states. Unfortunately, too many people fail to recognize the ESA as the conservative law it is. President Reagan once rhetorically asked, “What is a conservative after all, but one who conserves?” Conservative political theorist Russell Kirk went even further, writing in a Baltimore Sun op-ed, “nothing is more conservative than conservation.”Wildlife, from apex predators to the tiniest insects, play an essential role in keeping the earth’s life-sustaining ecology healthy. Bears and wolves, by preying primarily on weak and sick moose, deer, or elk, make the populations of those ungulates healthier. And pollinators, such as bees and butterflies, are essential to our food crops. From my personal experiences, I have come to...
