Greenhouse Effect Date: Friday, Dec. 2
Name: Leon (10D)
Nowadays, greenhouse effect is a serious situation in the earth. Greenhouse effect become a topic that everybody is talking about it. Then, “What effects brings from the greenhouse effect to this world?” is a popular question. And lots solve plans to apply in different object (like, human, government, country, etc.), and by different ways can bring which side’s benefits.
The reason of greenhouse effect produce is that the atmosphere can let sun’s shortwave radiation arrive ground, earth’s sur face get heat and send lots longwave radiation outside but absorption by atmosphere. In this way, earth’s surface and lower atmosphere have keep warm role like that what use to plant crops named greenhouse, this effect called greenhouse effect. Since the industrial revolution, human send carbon dioxide and gases what has good heat absorptivity in atmosphere increase every year, also atmosphere greenhouse effect increase. The principle of greenhouse effect is that solar radiation mainly is shortwave radiation, while ground radiation and atmospheric radiation are longwave radiation. Atmosphere heat absorptivity is good when the radiation is longwave radiation, heat absorptivity is bad when the radiation is shortwave radiation. When it is daytime, the sun shine on the earth, a part of energy absorption by atmospheric, and a part of back to universe, about 47% energy absorption by earth’s surface. At night, earth’s surface send infrared to universe to send out energy that absorption in daytime, a part of absorption by atmosphere. The atmosphere like glass what cover greenhouse to keep heat, let earth do not like moon that not have atmosphere. When sun shine it, the temperature rise quickly. But when the sun drop down, the temperature drop quickly. Many of scientists said because of greenhouse gases increase, let the earth keep heat energy increase, lend to global warming.
How to solve this problem, study from 3 angles. First, the human who live in this world, human is a big part in this problem. Everyone should protect environment. For example, protect forest, damage of forest is a big problem, estimate 1~2t carbon every year, and trees can absorption carbon dioxide, in 2050. (data for Chain forest country administration) And human also can do other things, like travel by bike, do not use car, train, or plane. But if they plant a lot of trees, human lose land to do other things. Second, governments in each area. Governments can organize study team to study how to do, and let citizen to do that. For example, do not use fluorine chlorine carbide, estimated effect 3% to reduce quality of produce carbon dioxide, in 2050. (Heilongjiang educational, 2013) And government can research other mothed to reduce greenhouse gases to send. But if they do that, they will lose something and then they must study new thing to instead of it. Third, each country on this world. Every country should make different kinds of laws to various control people. For example, to improve the fuel and other energy, because the mainly part of fuel is greenhouse gases, estimated reduce 5% in 2050. (study from Japanese government) And country can control governments and people to do better. But if they improve to using energy, they will do lots of study to do, maybe it can pollution more.
The above of three ways to solve problem. In my opinion, the first one is the best, because the earth is composition for people, although government and countries can list some plans to let them do something that good for earth. So, people is a main part in this world. People should do ourselves in more possible they can. So, if everybody can do them own part, it is better than let government or countries to organize. Because if government and countries give good examples or wonderful plans but no one follow it, it is nothing to help.
In this world, greenhouse effect is more serious than before. So, if they let it make earth warmer than before, people are in danger. Finally, people can get know solve greenhouse effect problem is important.apply in different object (like, human, government, country, etc.), and by different ways can bring which side’s benefits.
