Global warming

Global warming is an international problem. Because, global warming cause many environmental problems. For example, there are reductions in glaciers, a rise in ocean level, a change climate and a bad influence for an ecological system. An ecological system is the ocean cycle. Surface seawater and deep seawater revolve around the earth. If global warming advances, the ocean cycles stop. A greenhouse effect gas increase based human’s activity which is cause of global warming. A greenhouse effect gas is consisting of carbon dioxide, Freon, methane and so on. A scientist said that a glacier disappear every summer in the second half of 21 century and the sea level rise 17 centimeters through 20 century. So, global warming is the best serious international problem.


One solution to the problem of air pollution is to cut carbon dioxide(CO2). If you cut carbon dioxide (CO2), all problems were settled. You have two answers to cut carbon dioxide (CO2). First, you reduce garbage. When you went shopping, you took economical bag. I use always economical bag. If a vinyl bag was burn, a carbon dioxide occur a large quantity. So, economical bag is very good item. Second, you should use a public institution. A car is the worst transportation. Because, a car is occurred a lot of carbon dioxide (CO2) than the other transportation. If all of us use a train and bus, carbon dioxide was reduced extremely. I think human break environment, so we should devote ourselves solely to taking measures. If we don’t take measures, the earth will fall. The circumstances our effort , the earth is saved. If the whole human do two things, global warming will be stopped.
