Which scientist sparked the modern environmentalist movement with writings on pesticides?

• A. Rachel Carson
• B. Charles Darwin
• C. Alfred Wegener
• D. Carl Sagan

Answer: (A)

Understanding how a single influential work can spark a modern environmental movement. Rachel Carson’s Silent Spring exposed how pesticides like DDT move through ecosystems, accumulating in organisms and causing widespread harm to wildlife and potentially human health. By connecting chemical use to tangible ecological damage and presenting solid evidence, Carson helped raise public awareness, energized scientists and policymakers, and catalyzed major regulatory changes and the creation of stronger environmental protections. This shift laid the groundwork for the modern environmentalist movement and ongoing pesticide regulation. The other figures were pioneers in different fields—Darwin in evolution, Wegener in plate tectonics, Sagan in astronomy and science communication—so they did not spark the pesticide-focused environmental awakening in the way Carson did.
