Global Warming

Global warming has become a serious problem in modern world. Global warming can produce really dangerous climatic changes apart from a rise in temperature. For example, over the past 100 years the average temperature rise was about 1 degree. According to some scientists global warming is the result of the industrial revolution. One of the most important reasons of global warming is the air pollution. It would be a good idea to recycle the things that we don’t use anymore. Cars should switch to electric refueling, while factories shouldn’t isolate carbonic gas. We should also reduce the use of different sprays and lacquer, which destroy the ozone layer. If we take these simple measures, we might save our planet.
