Edwin Chadwick's 1842 report concluded that the accumulation of waste in rapidly industrializing cities was the primary cause of cholera and other deadly epidemics.

This publication spurred the passage of the Nuisance Removal and Disease Prevention Act of 1846.
New York City managed waste during the 19th century by allowing thousands of pigs to roam the streets freely and consume the city's refuse. These animals acted as living garbage trucks that converted human and animal waste into meat and lard. The practice persisted until the late 1800s when cities began to experiment with solid waste disposal methods that did not rely on animals.
Rachel Carson published Silent Spring in 1962 to warn that pesticides like DDT were killing songbirds and damaging the environment. Her book forced government interventions including the creation of the Environmental Protection Agency and transformed waste management from a simple disposal problem into a complex issue of ecological sustainability. This shift laid the groundwork for circular economy principles and zero waste initiatives.
