Recently, environmental problems have been more and more serious all over the world. Though many scientists have been studying hard to solve them, they haven’t become better. To solve these serious problems, people should know about them. There are many types of environmental problems and most of them are caused by people’s lives. Environmental problems can be classified on the basis of the place they happen.
First, some of them happen in the air. They are called air pollution. One of the best-known things is the depletion of the ozone layer. It is mainly caused by the CFC gas, also called freon, released from refrigerators, air conditioners, and so on. It destroys the ozone layer and makes an ozone hole. If the ozone hole becomes bigger, people would be bathed in more ultraviolet rays, which cause diseases like skin cancer.They also happen in the water. One of them is acid rain,
defined as “rain or any other form of precipitation that is unusually acidic” (Quoted from Wikipedia). It is caused by combustion of fuel or volcanic activities. It acidifies lakes, makes forests die and liquefies metal. Water pollution and the rise in ocean level are also this type of environmental problem.Finally, they happen on the land. A typical example is deforestation. It is caused by felling and burning trees. People do such things to sell wood, build new leisure spots, and so on.
It not only robs animals of their dwellings, but also increases CO2, which causes global warming. The other problems in this type are garbage pollution, desertification, and so on.There are still many kinds of environmental problems. All these types of problems listed above are only a part of them. Moreover, all the problems relate to each other. Some of them cause others. Albert Arnold Gore, Jr., an American environmental activist and the forty-fifth Vice President of the United States, said people are responsible for environmental problems now, in his book, “An Inconvenient Truth”. As he said, each person should have responsibility and try hard to solve these problems as soon as possible. There are a lot of things he or she can do for the environment.
