…There was a strange stillness. The birds, for example — where had they gone? Many people spoke of them, puzzled and disturbed. The feeding stations in the backyards were deserted. The few birds seen anywhere were moribund; they trembled violently and could not fly. It was a spring without voices … only silence lay over the fields and woods and marsh.
—from “A Fable for Tomorrow,” the opening chapter of Rachel Carson’s Silent Spring, which was published on this day in 1962
