Tell me about your feelings about land desertification.

Land desertification desert is the product of arid climate. There were deserts on the earth long before human beings appeared. However, there is no insurmountable boundary between the desolate desert and the fertile grassland. With water, lush plants can grow in the desert and become an oasis full of vitality; Without water and plants, green space can quickly degenerate into a piece of rubble. In order to get more food, people ignore the climate and land conditions, open up wasteland casually and overgrazing; In order to solve the fuel problem, regardless of the consequences, cut trees and mow grass at will. Arid and semi-arid areas were originally short of water and windy, but now the land has been ravaged, the vegetation has been destroyed, the precipitation is less, and the wind is getting stronger and stronger. Strong winds strongly erode the topsoil, sand is more and more, and sand dunes are slowly developing. This makes arable land a desert unsuitable for grazing and farming.
