The publication of Rachel Carson's Silent Spring, a compelling blend of stories, natural history, human values, and biological facts, in 1962 was instrumental in launching the modern environmental movement. We consider Carson's attitude toward animals in Silent Spring and in her other writings. Carson favored responsible stewardship and was more of an animal welfarist and environmentalist/conservation biologist who privileged ecosystems and species than an animal activist who privileged individuals, and she did not advocate an animal-rights agenda. There is clear tension in Carson's writings. Often she seems troubled by attempting to come across as a moderate and practical scientist, and some of her words, when considered out of context, could lead one to label her as an animal-rightist. While some of Carson's writing favors human-centered interests, she did not believe that only humans counted. Her warnings about silent springs must be taken seriously, perhaps even more seriously than when they were penned more than four decades ago. Carson was a passionate and extremely influential activist and if a world of persons like her were in charge of our global environmental policies, we and our fellow animals would be in much better shape than we currently are.
