Rachel Carson was born in 1907 in Pennsylvania and died in 1964. She was a marine biologist, scientific writer and she worked for the United States Fish and Wildlife Service. She wrote several books about the interconnection of life and human dependence on nature including The Silent Spring and The Sea Around Us. She graduated from Pennsylvania College for Women in 1929 and received a master's degree from Johns Hopkins University in 1932. (Novick)
The Writing
The Silent Spring was published in 1962. It attacked the agricultural use of chlorine containing pesticides, mainly DDT (dichloro-diphenyl-trichloroethane) (Novick). Carson claimed that insects ate the DDT sprayed leaves and were then eaten by birds who either died or had eggs whose shells were too thin, which resulted in a decrease in chick births. She called the book "Silent Spring" because DDT would eventually kill all birds, so there would be no cheerful songbird songs sung in Spring (Silent Spring). Fish also ate the DDT bugs, so this one pesticide resulted in the deaths of birds, fish, and insects and almost drove some species, like the bald eagle, to extinction. She also presented evidence that DDT could contaminate human food and water supplies (Novick).
The Problem
In the 1950s (the decade before The Silent Spring was published), hundreds of millions of pounds of pesticides had been applied to crops in the U.S. There is evidence that shows that DDT was harming humans, it probably also causes cancer. Again, it is very harmful to birds, fish and insects, in low concentrations causing birth defects instead of immediate death (Silent Spring).
The Action
Carson's book lead to restrictions on pesticide use and a ban on DDT in the US in 1972 (Novick; Silent Spring). Carson herself was called to testify before Congress and President John F. Kennedy created a commission to investigate chlorine containing pesticides (Silent Spring). Eventually, DDT was banned or regulated in most other countries (Sideris).
