My great-great-grandfather Theodore Roosevelt has the accurate reputation of being one of our country’s greatest conservationists. Images of TR embracing the great American outdoors by roping cattle on his ranch, hunting buffalo on the plains, and standing next to the Grand Canyon are just as ubiquitous in American history as the images of him working behind his desk in the Oval Office. His love for the natural world became one of his crowning policy achievements as president. To put it in context, the U.S. Forest Service once calculated that he preserved 230 million acres of land, or 84,000 acres for each day he was president.
