The consequence of climate change is serious. It will cause sea level rises，more flooding and stronger storm. Secondly, the shortage of fossil fuels is also a big problem, which is means fossil fuels are finite and non-renewable. If people cannot use them reasonably and economically, fossil fuels will be used up very soon. Klass model is a good illustration of this problem and it assumes a continuous compound rate and computes fossil fuel reserve depletion times for oil, coal and gas of approximately 35, 107 and 37 years, respectively (Shahriar & Erkan, 1).
Jeffrey Owens April 19, 2011 Geography, 100 Removing the Purple Mountain Majesties The use of Coal in America has become second nature to United States citizens, and American corporations. Coal is used for energy across the U.S., and is very important to the economy and the structure of our nation. Using coal for electricity has become as American as hot dogs and automobiles and while coal is very necessary and useful, some as destructive and controversial views some of the means by which the coal is recovered. Mountaintop removal has is one of these means of obtaining coal, and has sparked interest and outrage across America. Although the benefits of coal are numerous and extensive, Mountaintop removal is detrimental to the environment
As we are theoretically reaching “peak oil”, “peak gas” etc. as well as the occurring of global warming and a number of environmental issues, the call for more “clean”, “sustainable” renewable energy has been increasing dramatically. However, some critics argue that renewable energy such as wind, solar, biomass, alone can not sustain the world in the future. In this essay, I will argue that renewable energy is not a viable way for replacing established energy sources by analyzing the geographic and natural limitations, impacts on ecosystems and the efficiency on cutting greenhouse emissions of renewable energies. The real solution should be reducing energy consumption.
Business Economics GM545 Question 1 Supply and Demand? Where would we be without it? There will always be someone supplying a service or product, while the consumer needs that service or product. One of the biggest products that we use today is fossil fuel. Fossil fuel contributes too many products, the biggest being gasoline.
The high content of carbon causes global warming and global warming causes climate change. These changes are destroying our blue planet and making the ecosystem become sicker. Unfortunately, all the high content of carbon was released by human activities. We must reduce Carbon Dioxide emissions in the next two to three years, or we will lose our natural environment that we depend upon for survival. The 11th Hour shows us the consequences of irreversible global warming that have already begun to affect our life and environment.
As a result of man made activities such as the burning of fossil fuels and deforestation, the amounts of all of these gases in our atmosphere has greatly increased. Forests are extremely vital as they assist in naturally removing carbon dioxide and other polluting gases from the air. The concentration of carbon dioxide in our atmosphere has increased by over 30% within the past two centuries and levels of methane have doubled. In cities, many human activities have contributed to the amount of air pollution we have. There are two main sources of air pollution: anthropogenic sources (human activity) and natural sources.
(UN Chronicle, 2013). Predictions suggest that coral reef ecosystems could be lost by the end of the 21st century. Carbon dioxide levels will increase in the atmosphere to 600ppm over the next 100 years, the oceans pH will drop by 0.1 to 0.3 units and laboratory and field experiments and climate models show that even the lower acidification levels will slow the calcification of corals and growth by almost 50% by 2050. Under more extreme acidification, coral skeletons will dissolve entirely. (Eoearth, 2008).
Fossil fuels, those substances that move our cities, communicate our countries, make our life style possible, those precious elements we all know, are nonrenewable resources. In reality this is not the real issue, it is something that we cannot control and that anyway is going to happen; the problem is, what are we going to do after that happens? “Oil peak is the point at which irreversible decline of oil supplies around the world begins.” “This is based in the M. King Hubbert's theory that explains that as an oil field, that reaches its maximum and then its production rapidly declines until nothing is left, the earth´s oil supply will peak and this will lead us to a terminal decline of the availability of this resource”. Even though it is
Scientists predict that if the increase in greenhouse gas emissions continues unabated, temperatures will rise by as much as 10 degrees Fahrenheit by the end of this century, potentially causing dramatic and irreversible changes to the climate. The consequences, both anticipated and unforeseen, will have profound ramifications for humanity and the world as a whole. Water supplies in some critical areas will dwindle as snow and ice disappear. Sea levels will rise, threatening
People around the world highly depend on fossil fuels. Fossil fuels has powered the industrial revolution and helped to make the western world what it is today. But each year its becoming clearer that our uncontrollable use of fossil fuels is making us problems and will harm us in the far future. Fossil fuels have many uses that we depend on for instance if we don’t extract fossil fuels we won’t be able to use cars, airplanes, and trains. Moreover we use fossil fuels to power electricity plants and to heat our homes.
