Transcript of Earth Day

EARTH DAY!!! Ancient Cultures Air pollution has always been with us. The forging of metals was a key turning point in the creation of significant air pollution levels. Ice samples of glaciers in Greenland indicate increases in pollution associated with Greek, Roman, and Chinese metal production. Official Acknowledgement King Edward I of England banned the burning of sea-coal by proclamation in London in 1272. Air pollution would continue to be a problem in England, especially during the Industrial Revolution and continuing up to the Great Smog of 1952. This same city also recorded one of the earlier extreme cases of water quality problems with the Great Stink on the Thames of 1858. That led directly to the construction of the London sewerage system. The industrial revolution gave birth to environmental pollution as we know it today. The emergence of large factories and the consumption of significant quantities of coal and other fossil fuels gave rise to unprecedented air pollution. The large volume of chemical discharges added to the poisoning of the water system and the growing amount of untreated human waste. As the quote from Nemo says, "All pipes lead to the sea." River and ocean life suffered. Modern Awareness Pollution became a popular issue after World War II, due to radioactive fallout from atomic warfare and testing. Then a non-nuclear event, The Great Smog of 1952 in London, killed at least 4,000 people. (Scientists estimate as many as 12,000 deaths!) This prompted The Clean Air Act of 1956, one of the first major legislative steps in protecting the environment. Pollution began to draw major public attention in the United States between the mid-1950s and early 1970s, when Congress passed the Noise Control Act, the Clean Air Act, the Clean Water Act, and the National Environmental Policy Act.
