who made major contributions to environmental protection in the early 1900s
Conservation movement President Roosevelt put conservationist issue high on the national agenda.[18] He worked with all the major figures of the movement, especially his chief advisor on the matter, Gifford Pinchot and was deeply committed to conserving natural resources. He encouraged the Newlands Reclamation Act of 1902 to promote federal construction of dams to irrigate small farms and placed 230 million acres (360,000 mi2 or 930,000 km2) under federal protection. Roosevelt set aside more federal land for national parks and nature preserves than all of his predecessors combined.[19]

The Administrator is nominated by the President of the United States and must be confirmed by a vote of the Senate. The office of Administrator of the Environmental Protection Agency was created in 1970 in legislation that created the agency.
