The environmental movement and shifts in “attitudes toward the environment… is often dated from the publication of Rachel Carson’s Silent Spring” in 1962 (Lavigne, Scheffer et al. 1999). Rachel Carson, shown here in her official FWS photo from 1940, published the book which launched her into the public eye and launched the entire environmental movement.
This movement drew attention to the fact that we were affecting our environment in myriad ways. Ken Norris wrote, “we were all part of the larger worldwide realization, during the 1960s, that we humans were dealing with our world, and all the things it, in ways that had to be changed” (Norris 1991).
