Write a composition about the warming weather 100.
With the rapid development of human high technology, the side effects of science are gradually emerging, and global warming is an example. The weather is hot, and soaking in air conditioning in the heat has become a new "hobby", but have people ever thought about the negative effects that air conditioning will bring? Of course, the answer is yes. The gas discharged from air conditioners contains a lot of methane, which is also a gas that causes global warming. At the same time, air conditioning will waste a lot of electricity, so try to avoid using air conditioning.
And another reason is: carbon dioxide! Automobile exhaust and factory exhaust contain a lot of carbon dioxide, which is the most likely to cause greenhouse effect (that is, global warming). There are more and more cars now. According to statistics, there will be 700 million cars in the world by 2 1 century. Many exhaust gases have seriously affected us, such as cough, sore throat ... and most importantly, global warming. Statistics show that the per capita carbon dioxide emissions in the United States have reached 20 tons a year! China's annual per capita carbon dioxide emissions are also 2.5 1 ton a year! The environment around us is undergoing serious changes.
