“This has happened because insects, in a triumphant vindication of Darwin’s principle of the survival of the fittest, have evolved super races immune to the particular insecticide used, hence a deadlier one has always to be developed—and then a deadlier one than that…Thus the chemical war is never won, and all life is caught in its violent crossfire.”
– Rachel Carson, American biologist
根據達爾文的「進化論」，昆蟲對殺蟲劑產生抗體，人們不得不再發明更毒之物，昆蟲進化適應後，新一種毒物會推出市面……這場化武競賽不會勝利之餘，世上所有生命都會受到牽連。
– 瑞秋卡森，美國生物學家
