Theodore Roosevelt

Roosevelt's lasting domestic mark is public land. He placed around 230 million acres under federal protection, created the Forest Service and used the 1906 Antiquities Act to declare national monuments, a power presidents of both parties still use. The same year brought the Pure Food and Drug Act and the Meat Inspection Act, the roots of today's Food and Drug Administration. His trust-busting reputation is larger than its results, and the reserves sometimes meant removing people who already lived and hunted there.
