According to statistics, if there are some glaciers in Africa, they have almost completely melted, while glaciers in other parts of the world are gradually decreasing. Because of the serious industrialization, the early earth was still green vegetation, and later it was polluted into a serious smog. In the past, because of the development of Britain, the city was once filled with black smoke, and nothing could be seen between people. After learning the lesson, Britain attached great importance to this matter, and then improved urban governance. However, except Britain, many countries in the world are developing industries, and some countries are not perfect in environmental governance. So global warming is getting more and more serious, and even our ozone layer is being destroyed step by step. You know, if there is no such defense at all, people can't survive on the earth. If all the glaciers melt, the sea level will rise sharply, which will mean the disappearance of their homes for some islands or other cities. According to statistics, if all the glaciers in the world really melt one day, 900 million people will be completely submerged. Although all icebergs will not melt in an instant, it is an undeniable fact that icebergs are decreasing all over the world now. It is quietly changing, and its impact on people is not only the living environment, but also the possibility that our fresh water will be less and less. You know, water is very important to a person. If this continues, the world may be seriously short of water. In addition, some rare animals will be endangered. They have no living environment and can only disappear bit by bit. And in recent years, I have always heard that people's evaluation of the weather is very abnormal, but all this is because the environment has caused the health of the earth to get worse and worse, and the environment in which we live is changing bit by bit.
