Global DDT Overuse (1940s-1970s)
“The robins are dying!” Concerned citizens noticed birds trembling after DDT spraying. Initially celebrated for controlling mosquitoes, the pesticide accumulated silently up the food chains. Predatory birds laid eggs with shells so thin they collapsed under their parents’ weight. Species approached extinction before Rachel Carson’s “Silent Spring” finally alerted the public. This agricultural chemical disaster required decades of protection efforts after DDT bans to reverse wildlife population declines.
