Who is known for leading the environmental movement with 'Silent Spring'?

• A. John Muir
• B. Aldo Leopold
• C. Rachel Carson
• D. Greta Thunberg

Answer: (C)

This question tests your knowledge of who sparked the modern environmental movement with a landmark book. Silent Spring, published in 1962, exposed how pesticides—especially DDT—manipulated ecosystems, harmed wildlife, and could affect human health. Carson’s clear, evidence-based writing helped the public see the connections between everyday chemical use and environmental damage, which energized scientists, policymakers, and ordinary people to demand change. The result was a shake-up in environmental regulation and the rise of a broader conservation ethic that shaped policy for decades. The author behind this pivotal shift is Rachel Carson.

Context about other figures: John Muir focused on wilderness preservation and the creation of national parks, while Aldo Leopold emphasized land ethics and conservation. Greta Thunberg is a contemporary climate activist who has mobilized youth and global action in recent years. None of these are the author of Silent Spring, which is why Carson is the correct match for this question.
