Silent Spring: A book that changed the world - a podcast by BBC World Service

Silent Spring, written by marine biologist Rachel Carson, looked at the effect that synthetic pesticides were having on the environment. Within years of its publication in 1962, the widespread use of DDT had been outlawed in the USA. Louise Hidalgo has been speaking to Carson's adopted son Roger Christie about the author and her work.
