Now the Yellow River is facing the problem of cutoff. In 1997, it was cut off for 226 days. At the same time, the amount of water flowing into the sea of the Yellow River is decreasing. From 1990 to 1994, the annual average amount of water flowing into the sea is only 18.4 billion cubic meters, which is 64% of the average amount of 28.6 billion cubic meters in the 1980s, 59% of the average amount of 37.1 billion cubic meters in the 1970s and 47% of the average amount of 49.2 billion cubic meters in the 1960s. Some experts predict that if we take five years as a unit, the lower reaches of the Yellow River will be cut off every year by 2000, and the lower reaches of the Yellow River will be dried up every year by 2020, thus the Yellow River will become an inland river. All these problems are mainly caused by natural and social factors. Therefore, to improve the natural environment, we should first plant some trees and plants with high survival rate on both sides of the Yellow River! We often launch artificial rainfall bombs, so that the trees beside the Yellow River can keep the water content of the soil and water. In the past, because of the dense virgin forest on both sides of the Yellow River, it can play the role of soil fixation and sand prevention. So I think that as long as the trees and plants can survive, the sediment on both sides of the Yellow River can be controlled and the mother's River can last forever.
我们要保护好我们的美好家园,那就要从身边的小事做起。保护环境,让黄河之水永远气势如洪的流淌着吧!
