solution of ice shelf collapse

Now global warming is very serious. Global warming caused the Ice shelf collapse. According to the articles “Global warming blamed for ice shelf collapse”, “It is thought the warming of the atmosphere, which has been happening several times faster on the Antarctic Peninsula than the global average, has melted more surface ice, which is weakening the shelf” (2008, para.5). Global warming caused temperature to go up and high temperature makes ice collapse. So, the ice shelf collapse caused the sea level to increase and break the ecosystem. According to the article “Warming to Cause Catastrophic Rise in Sea Level?”, “However, the biggest danger, many experts warn, is that global warming will cause sea levels to rise dramatically. Thermal expansion has already raised the oceans 4 to 8 inches (10 to 20 centimeters)” (Lovgren, 2004, para.3). It might be very dangerous, because if sea level increased, islands may be buried. Our living areas will become smaller. Also, if the ecosystem is damaged, natural disasters might happen. All of those things happen, and we might lose our home, because the living area will get smaller.

Global warming will become more and more serious. According to the article “Seattle's serious about global warming”, “The current trajectory of climate change, if continued over the next 50 years, will take untold lives and cause widespread human suffering, destruction of coastal cities, loss of species and destabilization of the world economy” (Steinbrueck, 2007, para.1). If we do not find ways to solve those problems, we might repent our behavior. There are some solutions to improve environment problems. One is to not use plastic bags, another is to use public transportation, and the other is to not use Freon gas.

First, we should stop using plastic bags. When we go to the market to buy something, they put products in a plastic bag. Then, we might throw away the plastic bag. In the article “Plastic at your peril”, “Plastic is one of the major toxic pollutants of our time” (Our pharma correspondent, 2007, para.1). If the plastic rots, it requires a long time. Many times we are burying the plastic bag under the ground. When the plastic bag rots, it might pollute the environment. Now we have no idea about how to solve the problem of plastic. Even if we do something to improve it, it cannot be solved at the root. For example, if we burn the plastic bags, bad ingredients will flow out. It will destroy the atmosphere. In article “Plastic at your peril”, “Plastic causes serious damage to environment both during its production and disposal. So the only way to reduce the hazards of plastic is to reduce the use of plastic and thereby force a reduction in its production” (Our pharma correspondent, 2007, para.4).

Second, people should use public transportation or a family should have just one car. For example, we should use the subway, because the subway uses electricity. It can improve the environment. Now in many families they average 2 cars. It wastes resources. For example, there are two families. One family just has one car; the other family has two cars. They both live in the big city. The first family’s members sometimes use the car, but sometimes use public transportation. They might be very uncomfortable, but it can save good environment for their future generations. People should use more public transportation. In “Should roads have tolls to fight global warming?” the author said “Environmental groups consider the bills critical to a larger effort to get people out of their cars and into public transportation” (Garber, 2008, para.2). The other family is always using the car. In that family, the gas fee might be 200 dollars per month. It is very convenient, but it is very expensive and it is not good for the environment.

Third, people should stop using Freon gas. Now people are using a lot of heat in winter. We are using a lot of Freon gas in refrigerator. The Freon gas can make an ozone hole. In “Eliminating CFCs: It’s up to us” the author said, “Stratospheric chlorine and fluorine from the breakdown of CFCs is the cause of the Antarctic ozone hole” (Brownstein, 2000, para.3). So, the ozone cannot keep the sun’s harmful ultraviolet radiation. The sun’s UV immediateness reaches the earth’s surface. People might get skin cancer because of UV rays. In “Skin cancer”, “The most prominent cause of skin cancer is sun damage. This damage is caused by ultraviolet rays” (n.d. para.8) Also, it will make ice melt. It can raise the sea level. If the sea level increased, the natural disaster will happen, such as typhoons and floods.

Some people say global warming is not very serious and it is not a problem. They might think it is true. However I strongly disagree with them. Global warming is a big issue in the world. Global warming makes temperature increase. The high temperature makes North and South Pole ice collapse. It has caused sea level to increase. In “Global warming blamed for Antarctic Ice shelf collapse”, “Scientists say it is a sign of rapid climate change in a region that has experienced the greatest temperature increases on earth” (Skirble, 2008, para.1). If sea level still increases, it will be very dangerous for us. We should think about our future. Global warming is because of humans. Humans make environmental pollution. People throw away trash anywhere. When they do that, they never think about the end. They never think that the environment is very important. So, they just do everything they want, such as logging wood to earn money or polluting the environment.

In conclusion, now the sea level is increasing day by day. It is a serious problem for us. Most people do not know how serious this problem is. They think that as time passes all these things will be fine, but it is impossible, because we have already polluted the environment too deeply. We should find a solution to solve those problems. We should stop using plastic bags, we should stop using Freon gas, and we should use public transportation. If we do this, we might be able to improve the environment. However, if we still pollute the environment, it might give us no solutions to solve problems. We can improve the environment problems by our change. We can do it, and we must do it.

problem of writing ability

Most people use the Internet. Internet is very useful in our life. In Internet, we can do whatever we want to do, such as chatting, getting information, or playing games. Now, the high school students’ writing skill is very poor, because they use a lot of chatting words. “As more and more teenagers socialize online, middle school and high school teachers like Ms. Harding are increasingly seeing a breezy form of Internet English jump from e-mail into schoolwork” (Lee, 2002, paras.12-14). They are not using the academic language. It might decline people’s presentation ability. It is such a serious problem. How can we help them? We should find something to help them quit from the Internet.

Now the Internet has become an issue. The students are using a lot of Internet words in writing. So, their writing is very bad. We can make them do more outside activity and parents can put computers in the living room and make a time limit for computer.

First, parents can make them do more outside activity. Now, many students are using Internet to do chatting. They think Internet can teach them something. “In at least one central respect, proponents of technology in the classroom are on to something: Most students (60.9%) believe (the use of technology) improves their learning” (Guess, 2007, Para.17). They like chatting because they want to spend time with their friends. If they want talk about many things, they should type very quickly. So, they might shorten the words. If children do this a long time, parents should stop them. In America, parents want give their children more freedom, but they should be strict with their children. They can do some outside activity with their children, such as play soccer, play basketball, or go fishing. The children want to spend time with their friends, because they think parents do not have concern for them. So, if parents can spend a little time with their children, they might be able to shorten the time they use computer.

Second, parents can put the computer in the living room and make a time limit for the computer. For example, most teenagers have a computer in their own room. They can do everything they want. Nobody can control them. Parents do not know what their children do. If parents put a computer in the living room, parents can know what their children do when parents are in the living room. It might make the teenager use less Internet. If they are using less Internet, it might help them not have a writing problem. That is because too many students are writing short and they are using some little code, such as “I’m eat food”, “I’m study”. The students should be careful to write suitably and not use little code (Lee, 2002). Also, parents can set up a time limit on the computer. For example, before the teenager plays on the computer, parents can set up time that the computer is off.

In conclusion, both the middle school and high school students have writing problems, because they are using a lot of chatting words to write. It is a serious problem for us. We should help them. Parents should make their children do more outside activity and put computers in the living room. It might work for teenagers.

Ice collapse

In article “ Low probability of ice collapse,” the author talks about how the West Antarctic Ice Sheet will collapse. First, the WAIS can decide the sea level. There was an attempt at disintegration of a WAIS collapse. Second, researchers believe the WAIS is 13% of the ice in Antarctica has collapsed. Now the temperatures are increasing very quickly in parts of the West Antarctica. Next, Dr. David Vaughan said the ice sheet collapse’s probability is a low ratio. Finally, the Department for Environment said the sea level would be increased one meter per century.

Now the ice shelf collapse is very serious. If it still happens, it might give us a big disaster. There will be an unstable ecosystem, food resource war, and buried islands.

First, if ice shelf collapses still happen, it might make the ecosystem unstable. For example, when sea level increases by 10 meters, the animals and fish will follow the sea and move to another place. If they move to another place, they may affect human life. They might eat human food and hurt people. In Indonesia, there are many snacks that live with people. I hear this in Korean TV program. It is because of a broken ecosystem. They do not have place to live, so they move to the cities. It is very dangerous. If those things still happen, the tiger or lions will come to the city to hurt people.

Second, if the sea level still increases, a food resource war might happen. For example, when the sea level rises, the plain will be buried. If this thing happens, we will have no food to eat. If no ground can be given to us to grow, the food scramble might happen. When war happens, people will lose their home or die. Food is a very important thing in our life. If people cannot eat, it makes them crazy. When people’s minds are not clear, they can do any brutal things such as eat humans.

Finally, if the surface of the water rises, it can bury islands. For example, the sea’s surface increased day by day. The water could little by little bury an island. If this happened, people might lose their home, or might lose their families. It is very sad. Also, if people lose their home, they might move from islands to big cities. The big city’s population will increase to twice. The living place will be smaller and smaller. When you walk on the road, the people will encounter other people. It is a very uncomfortable life.

In conclusion, we should obstruct the ice collapse. If not, we might lose everything. If the surface of the water rises, an ecosystem will be unstable, there will be a food resources war, and island will be buried.
