Carson's landmark book "Silent Spring" (1962) exposed the harmful effects of pesticides, particularly DDT, on wildlife and the environment.

Carson's books focused only on marine life. - False.While Rachel Carson did write extensively about marine ecosystems in books like "Under the Sea Wind" (1941), "The Sea Around Us" (1951), and "The Edge of the Sea" (1955), her most influential work "Silent Spring" focused on the environmental impacts of pesticides on terrestrial ecosystems.
