2012 sees the 50th anniversary of the publication of Silent Spring by Rachel Carson.This book was to become a driving force behind the environmental movement, and as such was one of the most important books of the last century (for example, it was named one of the 25 greatest science books of all time by the editors of Discover Magazine). The book's premise was that human impacts on the natural environment, especially the use of agrochemicals (and insecticides in particular),would lead to the loss of birdsong and a 'silent spring'.Fifty years on, Silent Spring Revisited reflects on Carson's legacy, both in Britain, in the United States and beyond, and asks the question - do we still face the prospect of a future silent spring?The book looks at each of Britain's songbirds and other birds that contribute to the dawn chorus, and reflects on their changing fortunes in that half-century period. It will illustrate how each has fared, and call on testimony and recollections from conservationists, nature lovers, poets and others.Silent Spring Revisited reminds us that the principles that Rachel Carson brought into sharp focus in 1962 remain as important as ever.
