I am Hironori Aoki. I am from Tokyo. Today, I introduce international environment problem. Recently, this problem is being a matter of life and death. If the temperature is increasing as it is, maybe, we may do not live the earth. Now, how do we solve this problem? First of all, when did this problem raise? When did the environment of the earth change? I searched for the issue of around here. The temperature has increased since 1900. This has especially increased all over the world since 1950. And, Intergovernmental Panel on Climate Change said that the average temperature have increased 0.74 degrees during 1906 to 2005 and sea level have increased at a rate of 1.8 mm every year during 1961 to 2003 and the average temperature will have increased 6.4 degrees and sea level will have increased 59 cm by the end of 21 century. In the second place, When the temperature rose I think that first the person of death is the third world person that is to say developing country. There are various people in all over the world. There is rich person but there are the person of living road and begging for money and foods too. She or he may not eat foods sufficiently. If the temperature rose he or she probably may starve. The child is dead because of the sickness and hunger one person every three seconds. The poverty robs the thirty thousand children of life at every year. About 250 million children take labor and it exists under dangerous almost of that exploited situation. If the temperature rises the children of the country may be deader. This is not the person of third would problem but we developed country problem. We developed country caused this problem. Our developed technology brought about this international environment problem. So we must solution this problem. We must appreciate this situation. Because we think of other people things, we tend to pass this issue. So I think that we would like to recognize this condition again. And we consider not the things of others but the things of mine. We must reduce carbon dioxide emissions. The absorption of carbon couldn’t catch up the carbon emissions in ecosystem now. So we need to reduce the carbon dioxide quantity which we exhaust of. I think that the best things that we should do is economy. If everyone does this solution this international environment problem don’t exist on the earth. Thank you for listening.
