Pollutionwe hear it every other day at school, college and read about it in newspapers. So what is it?
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;   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. In the public buildings the sanitary facilities were unbelievably primitive As a metropolis, Berlin did not emerge from a state of barbarism into civilization until after A British expert in concluded that Berlin represented "the most complete application of science, order and method of public life," adding "it is a marvel of civic administration, the most modern and most perfectly organized city that there is.
Chicago and Cincinnati were the first two American cities to enact laws ensuring cleaner air in Pollution became a major issue in the United States in the early twentieth century, as progressive reformers took issue with air pollution caused by coal burning, water pollution caused by bad sanitation, and street pollution caused by the 3 million horses who worked in American cities ingenerating large quantities of urine and manure.
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.
Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment.

Water Pollution in Bangladesh INTRODUCTION Water is the most vital element among the natural resources, and is crucial for the survival of all living organisms. The environment, economic growth and development of Bangladesh are all highly influenced by water - its regional and seasonal availability, and the quality of surface and groundwater.
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.
Though extreme care is practiced in that industry, the potential for disaster suggested by incidents such as those at Three Mile Island and Chernobyl pose a lingering specter of public mistrust. Worldwide publicity has been intense on those disasters.
The borderless nature of atmosphere and oceans inevitably resulted in the implication of pollution on a planetary level with the issue of global warming. Though their effects remain somewhat less well understood owing to a lack of experimental data, they have been detected in various ecological habitats far removed from industrial activity such as the Arctic, demonstrating diffusion and bioaccumulation after only a relatively brief period of widespread use.
A much more recently discovered problem is the Great Pacific Garbage Patcha huge concentration of plastics, chemical sludge and other debris which has been collected into a large area of the Pacific Ocean by the North Pacific Gyre. This is a less well known pollution problem than the others described above, but nonetheless has multiple and serious consequences such as increasing wildlife mortality, the spread of invasive species and human ingestion of toxic chemicals.
Organizations such as 5 Gyres have researched the pollution and, along with artists like Marina DeBrisare working toward publicizing the issue. Pollution introduced by light at night is becoming a global problem, more severe in urban centres, but nonetheless contaminating also large territories, far away from towns.
Blue drain and yellow fish symbol used by the UK Environment Agency to raise awareness of the ecological impacts of contaminating surface drainage. The major forms of pollution are listed below along with the particular contaminant relevant to each of them: Common gaseous pollutants include carbon monoxidesulfur dioxidechlorofluorocarbons CFCs and nitrogen oxides produced by industry and motor vehicles.
Photochemical ozone and smog are created as nitrogen oxides and hydrocarbons react to sunlight.
Particulate matteror fine dust is characterized by their micrometre size PM10 to PM2. Radioactive contaminationresulting from 20th century activities in atomic physicssuch as nuclear power generation and nuclear weapons research, manufacture and deployment.Water pollution is the contamination of water bodies, usually as a result of human activities.
Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment.
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring kaja-net.comion is often classed as point source or nonpoint source pollution.

Exactly what I needed. Environment Degradation: Environment is the first casualty for increase in pollution weather in air or water. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth.
