Pollution is the introduction of pollutants into the natural environment that cause adverse changes. Pollution can take the form of chemicals or energy, such as noise, heat or light. Contaminants, the components of pollution, can be foreign substances or energies or natural pollutants. Pollution is often classified as a point source or nonpoint pollution.
The burning of charcoal and wood, and the presence of many horses in concentrated areas made the cities the black wells of pollution. The industrial revolution brought an infusion of chemicals and untreated waste into local streams that served as water supplies. King Edward I of England forbade the burning of sea charcoal by proclamation in London in 1272, after his smoke became a problem. But fuel was so common in England that this name earlier for it was acquired because it could be transported away from Some banks by the wheelbarrow.
It was the industrial revolution that gave rise to environmental pollution as we know it today. London also recorded one of the first extreme cases of water quality problems with the great stench on the Thames of 1858, which led to the construction of London's sewer system shortly afterwards. Pollution problems intensified as population growth exceeded the neighborhood's ability to view their waste problem. Reformers began demanding sewer systems, and clean water. In 1870, health conditions in Berlin were among the worst in Europe. August Bebel recalled the conditions before a modern sewer system was built in the late 1870s:
"The sewage from houses collected on gutters that ran along the curbs and emitted a truly fearsome smell. There were no public restrooms in the streets or plazas. Visitors, especially women, often became desperate when nature The health facilities were incredibly primitive ... As a metropolis, Berlin did not emerge from a state of barbarism until civilization until after 1870. "
The primitive conditions were intolerable for a world national capital and the German imperial government led its scientists, engineers and urban planners to solve not only deficiencies, but to forge Berlin as a model city of the world. A British expert in 1906 concluded that Berlin represented "the most complete application of science, order and method of public life," adding that "it is a marvel of civic administration, the most modern and perfect city Organized that exists. "
The emergence of large factories and the consumption of huge quantities of coal resulted in unprecedented air pollution and the large volume of industrial chemical discharges added to the increasing burden of untreated human waste. Chicago and Cincinnati were the first two US cities to enact laws that guaranteed a cleaner air in 1881. Pollution became a major issue in the United States in the early twentieth century, while progressive reformers questioned air pollution caused by The burning of coal. Poor sanitation and street pollution caused by the 3 million horses that worked in American cities in 1900, generating large amounts of urine and manure. As the historian Martin Melosi points out, the generation that first saw cars replacing horses saw cars as "cleaning miracles." In the 1940s, however, smog caused by the car was a major problem in Los Angeles.
Other cities followed throughout the country until the early 20th century, when the Office of Air Pollution was created under the Department of Interior. Extreme smog events were experienced by the cities of Los Angeles and Donora, Pennsylvania in the late 1940s, serving as another public reminder. Air pollution would continue to be a problem in England, especially after the Industrial Revolution, and extending into the recent past with the Great Smoke of 1952.
Awareness of air pollution spread widely after World War II, with fears provoked by reports of the radioactive consequences of atomic warfare and evidence. Then a non-nuclear event, the Great Smog of 1952 in London, killed at least 4000 people. This led to some of the first major modern environmental laws, the Clean Air Act of 1956.
