Coal This study will define why the natural resource coal is critical to Australia. 1ai)Coal is a nonrenewable natural resource composed of carbon and hydrocarbons in the form of a black sedimentary rock. It is the most significant natural resource found in Australia, fueling a highly successful industry which in 2005-2006 generated $A.24.5 billion. The coal industry is essential to Australia's high standard of living because it creates significant employment in mining (employs approx 18, 000), production, preparation, transport etc leading to the urbanization of rural communities. This flow-on effect creates the entire infrastructure we see in modern cities, transport, hospital, shopping centres etc.
These industrial activities have raised atmospheric gases such as carbon dioxide which contribute to greenhouse gases. The extra amount of these gases mean there is a thicker layer, meaning the gases absorb outgoing long-wave radiation which traps in too much heat. Increasing amounts of CO₂, methane, nitrous oxide, water vapour and ozone all contribute to this. The main cause in this rise is the burning of fossil fuels such as coal, oil, natural gas and petrol. Since the industrial revolution the levels of atmospheric CO₂ have increased from 280 parts per million to 380ppm for the past 10,000.
Explain why oil exploration in the areas shown could lead to high economic and environmental costs (10) Oil exploration is the extraction of petroleum from reservoirs underground and using the substance to benefit people. For example using it for transport and industry. However continuous exploitation can lead to costs, which can be both economic and environmental. Figure 1 shows that Canada is a location that is currently exploiting oil, 170 billion barrels per year. With Canada being second to Saudi Arabia to have the largest stores of oil in the country, it can provide large amounts of oil without the need to dig large mines to get to it.
Fossil fuels, such as coal, oil and natural gas are energy sources which contain large amounts of carbon, any process that uses fossil fuels will add carbon dioxide to the atmosphere. Fossil fuels are a non renewable energy source as the process which makes them takes millions of years. A sustainable lifestyle aims to reduce an individual’s impact on the earth’s natural resources and take no more than the environment can supply and renew. It is a lifestyle choice which aims to
“Their influence is known as the greenhouse gases, which are carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor”(“American Meteorological Society 2007”). These gases mixes with the sun ultraviolet rays, disburse into the earth atmosphere with harmful results. Carbon dioxide from the burning of fossil fuels is one way the human activities effects the environment. Carbon dioxide from the exhaust of cars in heavily polluted cities, farming machinery such as tractors, and smokestacks of refinery companies are just some of the ways carbon dioxide gases are release into the atmosphere by human contributors. The nitrous oxide gases affect the aquatic ecosystem food web chains, which leads from the smallest phytoplankton up to the largest mammal, which is man.
Although we may be able to sustain a planet with some kind of civilization, the earth that we knew is gone. Oil and fossil fuels are attributed to manual labor and why we are prosperous and why our economies have grown. It is also why we have global warming and acid oceans. Rising temperatures and depleting oil reserves go hand in hand. Modernity may cease with global warming as half the biggest companies are oil companies, and oil is the essence of life.
2013).Pharmaceutical companies sometimes place active chemicals and waste into groundwater sources, in which almost all of the groundwater may be untreated which most likely cause contamination. (Herber, 2002). Abstract: Increase in the emissions of carbon dioxide by burning fossil fuels is the largest cause of environmental down grading resulting not only in global warming but also causing acid rain which alters the pH balance of ground water. Water is a universal solvent; however, its dissolving properties are very sensitive to changes in temperature and pH. Global economic growth has, unfortunately,
Global warming Do you believe in global warming? I don’t global warming has been a huge debate that will never come to an end. The liberals believe that humans play the biggest part of global warming because we burn fossil fuels and think we need to find a cleaner way to produce energy. The conservatives show that it’s the earth natural cycle and that the earth has been heating and cooling through out history. My views lean toward the conservatives side I believe in facts and proof.
Global Warming Louis Clemens HUM/111 11/20/2011 Katie Newbanks Global warming has become a major concern over the last century. The world is much hotter now than the past. Many reasons are to blame for this global temperature increase such as fossil fuels releasing C02 emissions. C02 emissions are released from coal, oil, and natural gas burning. Coal, natural gas, and oil are burned for energy in many ways such as cars and power plants.
Temperatures range from 70° F during the summer near the equator, to -195°F in the winter near the poles. Average daily temperatures rarely exceed -80°F. This massive swell in range of temperatures makes inhabiting the planet very challenging. As displayed from the video in my presentation, scientists are already hard at work trying to conquer this task. With the burning of extremely harmful greenhouse gases, we could stand to solve this problem by doing what we already do to pollute our own planet, just in a much more helpful scale.
