Practice S/R Global Warming

In Bhattacharya's (2004) article entitled "Global warming threatens millions of species," she mentions that global warming makes natural conditions worse, such as extinction of organisms and changing climate. Then, habitat destruction, invasion by alien species, and overexploitation by humans result from changing climate and result in extinction. Those studies state the possibility of making less damage. The author disagrees with those studies, because she thinks many species are slipping into extinction. Actually, she also doesn't want to harm the ecosystem with other opinions. She is concerned about how to prevent global warming. In other words, she argues we have to not try to reduce damage, but prevent global warming. As a result, she says we have to try to stop causing global warming.

Her argument is very logical, so preventing global warming is more important than reducing harmful results. Then, in the first part of the article, she explains the danger of global warming well. If we don't try to prevent global warming, we will get many serious problems. Thus, every person should the try to prevent global warming, and also we have to know what causes global warming. Then, the government has to encourage citizens to try cutting emissions of greenhouse gases, employing new energy, and employing efficient technologies.

First, reducing the quantity of greenhouse gas is a good way to prevent global warming. Actually, we emit a lot of greenhouse gas every day because we live in an industrial world. If we don't use gasoline cars, it is good to reduce greenhouse gas because cars make too much an carbon dioxide. This gas plays a big role in making global warming. For instance, an area which has many companies is hotter than the countryside or an island, even if they have the same latitude. The government should make a law to reduce greenhouse gas, expecially mass transportation.

Second, inventing new energy is also good for us. It is not only preventing global warming but also improving our life. In these days, many people try to make a new energy because we are in a shortage of energy resources. Nowadays energy is harmful for global warming, so we have to invent natural forms of energy. Thus, government has to help people who try to make new energy such as diesel and solar power.

Finally, inventing new technologies is also good to prevent global warming. Today, most people use gasoline cars. If we invent cars which have new technology to prevent global warming, we can reduce our problem. Also we can invent another thing, especially machines which ren on natural energy. Finally, we have to make new technologies as soon as possible.

In conclusion, we must try to do all of these, because global warming causes such big problems such as extinction of animals and plants. Then, sea levels will rise and many islands will disappear if global warming keeps going. Finally, humans will get many risks like diseases. Therefore, we should prevent global warming by cutting emissions of greenhouse gases, inventing new technology, and exploiting new technologies.
