Who reflected president roosevelt concern for natural environment?

President Franklin D. Roosevelt's concern for the natural environment was notably reflected in the work of his close advisor and conservationist, Harold Ickes, who served as the Secretary of the Interior. Ickes was instrumental in implementing New Deal programs that focused on environmental conservation, such as the Civilian Conservation Corps (CCC) and the establishment of national parks and forests. Additionally, Roosevelt's own commitment to conservation is evident in his establishment of the Soil Conservation Service in 1935, aimed at addressing soil erosion and promoting sustainable land use.
