It is precisely because of people's deforestation that there are fewer and fewer trees, and the land has lost the protection of trees and gradually turned into a barren desert. With the sound of people cutting down, trees fell down one by one. According to statistics, by the end of 1996, the desertification land in the world had reached 36 million square kilometers, accounting for 1/4 of the whole land area, equivalent to the total land area of Russia, Canada, China and the United States. Land desertification in China is still expanding at a rate of more than 3,000 square kilometers per year. There are oases in the desert, so we should also create oases in the desert. Just like the people of the United Arab Emirates, creating oases in the desert.
