Birds Started Falling Dead From the Sky

In the mid-20th century, people in American suburbs began finding dead and dying birds on their lawns, in their gardens, and under neighborhood trees. This video traces how a seemingly modern miracle of science—DDT—turned into an environmental warning sign, as the pesticide spread through insects, songbirds, and raptors, thinning eggshells, collapsing populations, and leaving a trail of silent backyards across the United States in the 1950s and 1960s. Told as a historical documentary, the story follows the rise of DDT after World War II, the mounting scientific evidence of its impact on wildlife, and the public outcry shaped in part by figures like Rachel Carson and her book “Silent Spring.” Through archival accounts, ecological research, and environmental history, the video shows how falling birds helped spark the modern environmental movement, influence new laws on chemical safety, and change how we think about the hidden costs of technological progress.
