what extent does Methane effect climate change and what are the uses and limitations of science in addressing this issue? Methane is influenced by various natural and anthropogenic factors such as landfills‚ farms‚ drilling for natural gas‚ and coal mining. All of these factors that generate Methane emissions create ground level o-zone which is not only hazardous for our health‚ but it is a great concern for our climate. EPA is one of several organizations that plays a significant role in encouraging

“Hydraulic Fracturing or Fracking is a process in which fractures in rocks below the earth’s surface are opened and widened by injecting chemicals and liquids at high pressure”(Dictionary). This type of mining is used to extract natural gas and oil by drilling a mile or more below the surface. Fracking has been “commercially used for 65 years”(Introduction)‚ supplying Americans energy. Hydraulic Fracturing has allowed for the increase in supplies of oil and natural gas. It is currently the best and

by injecting the area with a mixture of water‚ sand and other chemicals to release methane gas. Another source of fuel is the mining of coal. Unlike fracking‚ coal mining requires labor that is both physically demanding and hazardous. Mining for coal also requires a larger surface area and therefore could have a larger negative impact on the environment. The burning of coal contributes more CO2 emissions than the burning of natural gas derived from fracking. This combined with other statistics may

However‚ this is only part of the entire effect of mining on the environment. Mining affects the environment and humans in many different ways. It may be necessary‚ but even though mining is the only known way to extract some resources‚ it is doing more harm than good by

rock crusher is widely used in mining‚ smelting‚ building material‚ highway‚ railway‚ water conservancy and chemical industries. The rapid economic development is inseparable from the development of these industries. In the mining industry‚ with the coal industry consolidation‚ closure and merger of small coal mines‚ but the scale coal mines over the growing rise in coal production‚ have increased the demand for small rock crusher. In the next few years‚ mining in the western region in China has

supplied to form the lime (3.75 MJ/kg in an efficient kiln) is obtained by burning fossil fuel it will release CO2: in the case of coal fuel 295 kg/t; in the case of natural gas fuel 206 kg/t. The electric power consumption of an efficient plant is around 20 kWh per tonne of lime. This additional input is the equivalent of around 20 kg CO2 per ton if the electricity is coal-generated. Thus‚ total emission may be around 1 tonne of CO2 for every tonne of lime even in efficient industrial plants‚ but is

governments and companies are looking to unconventional fuel resources. This means the fuel is extracted via another method then the conventional well strategy. These resources include fracturing of oil and gas source rocks‚ methane hydrates‚ tar sands and coal seam gasification. There are benefits such as energy security and economic growth associated with these resources. However‚ there are environmental disadvantages which may prove detrimental to sustainability and an uncertainty in the future of energy

energy now is coal. Coal is the most abundant fossil fuel in the world (Berg and Hager 2007). Coal is used by the utilities companies to produce electricity. Coal is usually mined. There are two types of mining methods used with coal; one is surface and the other is sub-surface (underground). In the United States surface mining is used to obtain approximately sixty percent of all coal mined in the United States. Sub-surface‚ underground‚ accounts for the other forty percent of coal mined in the United
