What animals' lives are affected by cutting down trees?
Since18th century, a large number of immigrants came to the western plains of the United States, which led to three black storms in 1930s. 1A storm in May, 934, which lasted for three days and nights, blew from the west coast to the east coast, forming a gray-yellow dust belt with a length of 2,400 kilometers from east to west, a width of 2,400 kilometers from north to south and a height of 3,400 kilometers. The storm moved eastward at a speed of more than 100 km per hour, sweeping across the North American continent, sandstorms and dark days. In Kazakhstan in Central Asia, a large number of wasteland was reclaimed in 1950s, resulting in a large area of soil. Wind erosion, similar to the dust storm in the 1930s in the United States, has also occurred. In the desert of1160,000 square kilometers in the north of China, 39% is desertification caused by sandstorms caused by human factors. Sandstorm is a sudden and high-intensity sandstorm disaster. The direct economic loss caused by this in China is as high as 4.5 billion yuan every year. Northwest China, including Xinjiang, Gansu, Qinghai and Ningxia, as well as central and western Shaanxi and Inner Mongolia, are sandstorm-prone areas in China. 1On May 5, 1993, a severe sandstorm caused huge losses in parts of Gansu, Ningxia and Inner Mongolia, with 85 people killed, 264 disabled and 3/kloc-0 missing, resulting in a direct economic loss of 725 million yuan. Seriously affect the economic development of these areas. Tsunami can be regarded as a natural disaster to some extent, but it wouldn't have caused such a great tragedy if it hadn't destroyed the environment in coastal areas artificially.
