Pinchot's ideas inspired government policy that forests be protected for public use.

Explanation:

Gifford Pinchot, a well-known politician, a member of the progressive reforms of the Roosevelt administration, a figure in the field of environmental protection in the United States, substantiated the ideas of the careful and efficient use of resources. He led the US Forest Service and first introduced environmental management practices regarding forests, soil, and other natural resources. At the beginning of the 20th century, he was one of the key politicians substantiating the need for environmental protection, based on economic viability.

Pinchot was appointed by McKinley as Head of the Department of Forestry at the Department of Agriculture. In 1905, his department gained control of national forest reserves. Pinchot promoted private use (for a fee) under federal control. In 1907, Roosevelt allocated 16 million acres (65,000 km²) of new national forests.
