Sandstorm is a manifestation of the destruction of the ecological environment, and its harm affects all aspects of us. First of all, in terms of life, if we encounter a sandstorm, the sandstorm it brings will have an adverse impact on our respiratory tract, and even cause infection and endanger our lives and health. At the same time, sandstorm will reduce the visibility of the road and bring inconvenience to traffic. More importantly, dust storms will cause environmental pollution, aggravate the wind erosion and desertification of the surface soil, affect the production of crops, cause certain economic and property losses, and even more seriously reduce the "life span" of the earth.<br>The occurrence of severe and gradually frequent sandstorms is closely related to human behavior. With the gradual expansion of industrialization and the gradual increase of factories, the ecological environment of many areas has been damaged, even no grass. With the continuous expansion of the population, the construction of housing forced many forests to be cut down. The decrease of green plants aggravates the intensity of sandstorm. If people don't do something about it, nature will make us pay a heavy price sooner or later.<br>
