Pollution Problems

Motor vehicle emissions are one of the leading causes of air pollution., and are the world leaders in air pollution emissions. Principal stationary pollution sources include coal-fired plants, disposal activity, incinerators, large livestock farms (dairy cows, pigs, poultry, etc.), actories, metals production factories, plastics factories, and other heavy industry. Agricultural air pollution comes from contemporary practices which include clear felling and burning of natural vegetation as well as spraying of pesticides and herbicides^[16]

In February 2007, a report by the Intergovernmental Panel on Climate Change (IPCC), representing the work of 2,500 scientists from more than 130 countries, said that humans have been the primary cause of global warming since 1950. Humans have ways to cut greenhouse gas emissions and avoid the consequences of global warming, a major climate report concluded. But in order to change the climate, the transition from fossil fuels like coal and oil needs to occur within decades, according to the final report this year from the UN's Intergovernmental Panel on Climate Change (IPCC). bout 400 million metric tons of are generated each year alone produces about 250 million metric tons. Americans constitute less than 5% of the but produce roughly 25% of the world’s and generate approximately 30% of In 2007 has overtaken the United States as the world's biggest producer of CO₂. Air pollution comes from both natural and man made sources. Though globally man made pollutants from combustion, construction, mining, agriculture and warfare are increasingly significant in the air pollution equation. Pollution can also be the consequence of a natural disaster. For example, often involve water contamination from sewage, spills from ruptured or Larger scale and environmental damage is not uncommon when coastal or are involved. Some sources of pollution, such as plants or can produce widespread and potentially hazardous releases when accidents occur.

The development of nuclear science introduced which can remain lethally radioactive for hundreds of thousands of years, named by the as the "most polluted spot" on earth, served as a disposal site for the Soviet Union thoroughout the 1950s and 1960s. Second place may go to the area of Chelyabinsk U.S.S.R. (see reference below) as the "Most polluted place on the planet
