Some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally occuring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases: 1) Carbon dioxide is released to the atmosphere when solid waste, fossil fuels (oil, natural gas, and coal), and wood and wood products are burned. 2) Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from the decomposition of organic wastes in municipal solid waste landfills, and the raising of livestock.
This process is called greenhouse effect. In addition, greenhouse gases include carbon dioxide, nitrous oxide, water vapor, methane and Chlorofluorocarbon or commonly called CFCs. According to Mr. Steffen, “The primary cause of the observed changes in the Earth’s climate are human activities—mainly the burning of fossil fuels” (Steffen, 2013). The process of burning fossil fuel unleashes a huge amount of greenhouse gases, especially carbon dioxide, to the atmosphere, disturbing the balance of greenhouse gases in the nature. As stated by Slaght, “The accumulation of greenhouse gases in the atmosphere due to human activities will change th... ... middle of paper ... ...e replaced with little or no regrowth vegetation.
Global Warming Forewords Global warming is the result of a large concentration of CO2 and greenhouse gases (GHGs) in the atmosphere. Human activities such as burning fossil fuels, deforestation, and emissions are held responsible for this situation developing. The climate change is the result, and a factor of global warming. There are several factors impacting global warming, and these include ozone layer depletion, carbon cycle, pollution, human actions, and orbit of the earth. There is a debate going in the erudite circle on the role and responsibility of human actions in global warming.
Acid rain, created by air pollution, can also affect crops by making the soil acidic and water to become inhabitable for wildlife. Another issue that arises with air pollution is global warming. The atmosphere contains greenhouse gases that are responsible for keeping steady temperatures and the sun’s heat on Earth (“Health & Environmental Effects of Air Pollution”). By burning fossil fuels, humans have been releasing greenhouse gases. The conveyance of the greenhouse gases lead to global warming.
The greenhouse effect is a natural atmospheric process that is necessary for life, as we know it. Too strong of a greenhouse effect that is caused by the burning of fossil fuels and deforestation, may cause harmful environmental change. The greenhouse effect is only troublesome when it gets too strong and warms things too much. And that’s just what scientists say has happened over the last 150 years or so as the people of industrialized nations have extracted Earth’s vast buried stores of fossil fuels and burned them. Each greenhouse gas differs in its ability to absorb heat in the atmosphere.
It will produce Carbon Dioxide, which is the greenhouse gases from the factory when they burn the fossil fuels for energy as well as greenhouse gas emissions from some of the chemical reactions. And agriculture, greenhouse gases emissions come from animals such as cows, rice production and soils. The greenhouse gas emissions are from residential too. The use of certain products that contain greenhouse gas involved in the development of houses. Greenhouse gases will trap heat on Earth and it will affect the temperature.
These mines collect water from agricultural or domestic supplies, thus lowering them significantly. While producing A.M.D. or Acid Mine Drainage, effective in killing plant life. In addition, large amounts of land are used disturb the environment, animals and natural resources available in the area. However, once mined the coal is sent off to such places as coal power plants, which are then combusted, creating carbon dioxide going into the atmosphere effecting the carbon cycle greatly.
These additional greenhouse gases come from burning fossil fuels such as coal, natural gas, and oil to power our cars, factories, homes and schools. Cutting down trees, generating waste and farming also produce greenhouse gases. (EPA 3) Secondly, most radiation is absorbed by the earth’s surface and warms it causing the greenhouse effect. Some solar radiation is reflected by the earth and the atmosphere. Some of the infrared radiation passes through the atmosphere, and some is absorbed and re-emitted in all directions by greenhouse gas molecules.
Production and Maintenance of nuclear power is very expensive. Nuclear power is viewed as too dangerous, uneconomical, and not required. Although, nuclear energy has a potential hazard, but it is reliable in terms of efficiency, environmental impact and cost when compared with other sources of energy. Therefore, the increase in the demand of nuclear energy could be substantial. It was reported that: The inefficiencies and environmental hazards associated with the use of fossil fuels as sources of energy and the excessive cost an incapability of renewal energy sources to meet demand for energy, means that increasing reliance on nuclear energy is unavoidable (Brown, 1987).
Burning fossil fuels means using energy that is made up of decayed animals and plant matter. These fuels are also known as mineral fuels. “When we extract and burn fossil fuels such as coal or petroleum, we cause the release of carbon dioxide (CO2) and other heat-trapping ‘greenhouse gasses’ into the atmosphere” (Upham). This means that humans are causing harmful gasses to enter the atmosphere by using fuels like oil and coal. Dan Upham of the Environmental Defense Fund also states that natural levels of carbon dioxide are thirty percent higher than the reported levels in eight-hundred thousand years.
