Theodore Roosevelt

Teddy Roosevelt may have started out as an enthusiastic big game hunter, but he adopted conservation as his passion once he saw the decimation of the West. Roosevelt created the U.S. Forest Service, established several bird reservations, game preserves, national forests and five national parks. According to the National Park Service, Roosevelt protected about 230,000,000 acres of public land throughout his time as president.
