An exhibit at Michigan State University is revisiting the publication of "Silent Spring," which sparked public awareness of the effect of pesticides on the environment and human health.

"Echoes of Silent Spring: 50 Years of Environmental Awareness" is at the MSU Museum's Heritage Gallery and runs through Dec. 30.

The book written by Rachel Carson was published in 1962. The MSU Museum wants visitors to experience the exhibit, read the book and think about its impact.

Part of the exhibit showcases ongoing correspondence between Carson and Michigan State University ornithologist George Wallace, whose research was featured prominently in the book. Wallace's papers are part of the MSU Museum's collections.

The MSU Museum is the natural science and culture museum at Michigan State University.
