In the center were the conservationists, led by Theodore Roosevelt and his coalition of outdoorsmen, sportsmen, bird watchers, and scientists. They wanted to reduce waste; emphasized the value of natural beauty for tourism and ample wildlife for hunters; and argued that careful management would not only enhance these goals but also increase the long-term economic benefits to society by planned harvesting and environmental protections. Roosevelt worked his entire career to put the issue high on the national agenda. He was deeply committed to conserving natural resources. He worked closely with Gifford Pinchot and used the Newlands Reclamation Act of 1902 to promote federal construction of dams to irrigate small farms and placed 230 million acres (360,000 mi or 930,000 km) under federal protection. Roosevelt set aside more Federal land, national parks, and nature preserves than all of his predecessors combined.
