Which publication is credited with catalyzing Earth Day and the U.S. Environmental Protection Agency?

• A. The Jungle
• B. The Omnivore's Dilemma
• C. Silent Spring
• D. A Sand County Almanac

Answer: (C)

The main idea here is how a single influential publication can ignite a national movement and lead to new government action. Silent Spring documented the ecological and health dangers of pesticides, especially DDT, with careful evidence and a compelling narrative that made people rethink how society uses chemicals. That persuasive, evidence-based call for precaution helped spur widespread public concern and activism around environmental issues.

The momentum from that shift in public opinion contributed directly to the environmental movement that produced Earth Day in 1970 and to the push for a centralized environmental agency, which led to the creation of the U.S. Environmental Protection Agency later that year. In short, Silent Spring is credited with catalyzing both a broad public awakening and concrete institutional change.

The Jungle, by contrast, is famous for exposing food-safety abuses and prompting reforms in the meatpacking industry; The Omnivore’s Dilemma meditates on modern food systems and ethics without directly triggering the EPA or Earth Day; A Sand County Almanac emphasizes conservation ethics but predates the modern environmental movement and lacks that direct catalytic role.
