The United States holds less than 5% of the world\’s population, but due to large houses and private cars, uses more than 25% of the world\’s supply of fossil fuels. As the largest source of U. S. emissions, CO2 from fossil fuel combustion, accounted for 80 percent of [its] weighted emissions in 1998. Combustion of fossil fuels also produces other air pollutants, such as,
and. \”The is unique among industrial sectors in its very large contribution to emissions associated with nearly all air issues. Electricity generation produces a large share of Canadian nitrogen oxides and sulphur dioxide emissions, which contribute to smog and and the formation of fine particulate matter. It is the largest uncontrolled industrial source of mercury emissions in Canada. Fossil fuel-fired electric power plants also emit, which may contribute to climate change. In addition, the sector has significant impacts on water and habitat and species. In particular, and have significant effects on water and. \” According to U. S. Scientist Jerry Mahlman and USA Today: Mahlman, who crafted the IPCC language used to define levels of scientific certainty, says the new report will lay the blame at the feet of fossil fuels with \”virtual certainty,\” meaning 99% sure.
That\’s a significant jump from \”likely,\” or 66% sure, in the group\’s last report in 2001, Mahlman says. His role in this year\’s effort involved spending two months reviewing the more than 1,600 pages of research that went into the new assessment. Combustion of fossil fuels generates, and, which fall to Earth as acid rain, impacting both natural areas and the built environment. Monuments and sculptures made from and are particularly vulnerable, as the acids dissolve. Fossil fuels also contain radioactive materials, mainly and, which are released into the atmosphere. In 2000, about 12,000 of thorium and 5,000 tonnes of uranium were released worldwide from burning coal. It is estimated that during 1982, US coal burning released 155 times as much radioactivity into the atmosphere as the.
Burning coal also generates large amounts of and. These materials are used in a wide variety of, utilizing, for example, about 40% of the US production. Harvesting, processing, and distributing fossil fuels can also create environmental concerns. methods, particularly and, have negative environmental impacts, and poses a hazard to aquatic organisms. also have negative environmental impacts, including air and water pollution. Transportation of coal requires the use of diesel-powered locomotives, while crude oil is typically transported by tanker ships, each of which requires the combustion of additional fossil fuels. uses a variety of approaches to limit these emissions, such as command-and-control (which mandates the amount of pollution or the technology used), economic incentives, or voluntary programs. An example of such regulation in the USA is the \”EPA is implementing policies to reduce airborne mercury emissions.
Under regulations issued in 2005, coal-fired power plants will need to reduce their emissions by 70 percent by 2018. \”. In economic terms, pollution from fossil fuels is regarded as a negative. Taxation is considered one way to make societal costs explicit, in order to \’internalize\’ the cost of pollution. This aims to make fossil fuels more expensive, thereby reducing their use and the amount of pollution associated with them, along with raising the funds necessary to counteract these factors. [ According to Rodman D. Griffin, \”The burning of coal and oil have saved inestimable amounts of time and labor while substantially raising living standards around the world\”. Although the use of fossil fuels may seem beneficial to our lives, this act is playing a role on global warming and it is said to be dangerous for the future. Moreover, these environmental pollutions impacts on the human beings because its particles of the fossil fuel on the air cause negative health effects when inhaled by people.
These health effects include premature death, acute respiratory illness, aggravated asthma, chronic bronchitis and decreased lung function. So, the poor, undernourished, very young and very old, and people with preexisting respiratory disease and other ill health, are more at risk. Air and swamps If air (or rather the oxygen in the air) can get at dead plants, they decay (rot). This happens because microbes, which need air, feed on the plant remains and turn their carbon into carbon dioxide. It\’s really like slow burning. And as with burning, there\’s hardly anything left afterwards. All the carbon the plants took out of the air has gone back into the air. But when plants die and become part of a stinky swamp, the air and microbes can\’t get at the dead plant remains. Scientists call the resulting black stinky sludge \’anoxic\’, meaning \’without oxygen\’. This means that the carbon of the dead plants stays put and eventually becomes coal.
