Which Rachel Carson book is cited as helping set the stage for Earth Day?

Rachel Carson’s 1962 book Silent Spring helped set the stage for Earth Day.

The book documented how indiscriminate pesticide use, especially DDT, could harm birds, other wildlife, ecosystems, and potentially human health. Carson combined scientific evidence with vivid, accessible writing, bringing pesticide pollution to a mass audience and challenging the assumption that technological chemicals were automatically safe.

Silent Spring appeared eight years before the first Earth Day. Its success helped make environmental protection a major public issue, alongside events such as the 1969 Santa Barbara oil spill and the Cuyahoga River fire. These developments contributed to the political and cultural climate in which Gaylord Nelson and Denis Hayes organized the 1970 environmental teach-in.

The other choices are also influential environmental books, which makes the question tempting. The Population Bomb addressed population growth, A Sand County Almanac explored land ethics, and The Sea Around Us was Carson’s earlier book about ocean life. Silent Spring is the work most directly linked to the modern environmental movement and Earth Day’s origins.
