Pollution started from prehistoric timeswhen man created the first fires. According to a article in the journal Science, " soot " found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires. Core samples of glaciers in Greenland indicate increases in pollution associated with Greek, Roman, and Chinese metal production.

The Industrial Revolution brought an infusion of untreated chemicals and wastes into local streams that served as the water supply. King Edward I of England banned the burning of sea-coal by proclamation in London inafter its smoke became a problem; [6] [7] the fuel was so common in England that this earliest of names for it was acquired because it could be carted away from some shores by the wheelbarrow.

It was the industrial revolution that gave birth to environmental pollution as we know it today.

London also recorded one of the earlier extreme cases of water quality problems with the Great Stink on the Thames ofwhich led to construction of the London sewerage system soon afterward. Pollution issues escalated as population growth far exceeded viability of neighborhoods to handle their waste problem.

Reformers began to demand sewer systems and clean water. August Bebel recalled conditions before a modern sewer system was built in the late s: There were no public toilets in the streets or squares. Visitors, especially women, often became desperate when nature called.

As historian Martin Melosi notes, The generation that first saw automobiles replacing the horses saw cars as "miracles of cleanliness. Extreme smog events were experienced by the cities of Los Angeles and Donora, Pennsylvania in the late s, serving as another public reminder. Awareness of atmospheric pollution spread widely after World War II, with fears triggered by reports of radioactive fallout from atomic warfare and testing.

National news stories in the late s—especially the long-term dioxin contamination at Love Canal starting in and uncontrolled dumping in Valley of the Drums —led to the Superfund legislation of The development of nuclear science introduced radioactive contaminationwhich can remain lethally radioactive for hundreds of thousands of years.

Lake Karachay —named by the Worldwatch Institute as the "most polluted spot" on earth—served as a disposal site for the Soviet Union throughout the s and s.

ChelyabinskRussia, is considered the "Most polluted place on the planet". The toll on the worst-affected populations and the growth since then in understanding about the critical threat to human health posed by radioactivity has also been a prohibitive complication associated with nuclear power.A GLOBAL WATER-QUALITY CRISIS AND THE ROLE OF AGRICULTURE Water pollution is a global challenge that has increased in both developed and developing countries, undermining economic growth as well as the physical and.

Between million and million tonnes (between million and 14 million tons) of debris end up in the world’s oceans every year, and much of it is improperly discarded plastic .
