The book stated that uncontrolled pesticide use led to the deaths of not only animals, especially birds, but also humans. Its title was meant to evoke a spring season in which no bird songs could be heard, because they had all died from pesticides. Its title was inspired by a poem by John Keats, "La Belle Dame sans Merci", which contained the lines "The sedge is wither'd from the lake, And no birds sing."
