The third Conservation movement was summoned to life between Rachel Carson's The Silent Spring (1962) and the Santa Barbara Oil Spill at the end of the movement-spawning Sixties, and would be called by a more nature-evoking term—environmentalism. Looking back from there, those of us with some historical memory were struck by how far we had come from the first Conservation crusade led by John Muir, Theodore Roosevelt, and Gifford Pinchot, or the second led by FDR in the 1930s. In those early days they thought the problem was loss of forests, soil erosion, water and air pollution, and that the solutions were National Parks and National Forests watched over by civil servants in their gray or tan-brown uniforms, along with a Soil Conservation Service for farmers.
