Global Warming

Global Warming

The world economy has changed a lot over the past 10 years. Everything has changed; more dangerous energies are used such as, gas, oil, and electricity nowadays which cause a harmful affect on the environment and cause many problems. Two of these problems are pollution and global warming that have a really dangerous effect on earth. First of all I will outline some problems that cause pollution in more detail which will also cause the percentage of global warming to increase.

The main problem is that many people are not aware of global warming and what will happen to the earth in the near future, so they keep using things that are unnecessary to use, like, for example, they are producing the same item but in a different brand just to show which of the items are the best and they forgot the negative affect that they cause to the environment. Another problem is the carbon dioxide from power plants “In 2002 about 40% of U.S. carbon dioxide emissions stem from the burning of fossil fuels for the purpose of electricity generation. Coal accounts for 93 percent of the emissions from the electric utility industry.”(http://www.ecobridge.org/content/g_cse.htm). Moreover the radiation which is stacked inside the atmosphere causes the earth to warm up and causes global warming.

However there are lots of solutions for these kinds of problem that I am going to outline, and one of the major solutions is to make new laws for those who will harm the environment. Each person should have only a certain amount that he can use during the year. In addition to make cities aware of the problem like what California did “In 2006, California passed two groundbreaking laws to reduce California's emissions of carbon dioxide and other heat-trapping pollution” (http://www.solutionsforglobalwarming.org/1calpolicy.html ).
Another final solution is to stop cutting trees for crafting, making paper and try to look for a different source, although it is hard to replace the paper with another thing, but at least try. As David G. Bancroft said “All one can do is try every single day, regardless of the test, to live the truth, not to lie. Knowing this earthly stay is a short lived quest to the one most high, resisting to be led astray into evil’s fiery nest like those who defy and continue to betray, including angels once blessed”.

Cool Cities

Cool Cities
Now days, many cities in the world are modern and have basics needs to live, however, these cities consume more energy that produce more CO2 and heat. Therefore, the developers found out a basic strategy to deal with heat and CO2 by building Cool Cities. These cities have the ability to reduce heat and CO2 to the zero level. However, Cool cities are not practical for two main reasons. This essay will describe my research on cool cities and my recommendation.

The first reason is the size of the world population. For example, Masdar City is designed to be free from cars and any other polluting machines, but this city will serve only 50,000 citizens (Kawach). The world population rate is increasing year after another and by 2050 the rate will be approximately 10 billion. Therefore, we need many cool cities in each county which is impossible.

Another reason is the cost of building this type of city. Masdar City cost around $ 22 billion. Many countries around the world are poor and to have this type of city in them would be very impossible. This huge amount of many can be used to reduce CO2 level by developing the old factories and replace them with new one. Furthermore, this amount of budget can help to find many projects which have to be available and that are including poor countries.

In conclusion, having cool cities is a brilliant idea; however, most people can’t live in it. Therefore, I recommend that we should change our lifestyle and I believe that this is the solution for global warming.
