With the continuous development of science and technology, many wonderful natural landscapes and resources on the earth are disappearing. Even the world’s fourth largest lake and the largest salt lake in Central Asia are expected to disappear from our earth in 2020.
The Aral Sea is located at the junction of Kazakhstan and Uzbekistan and in the middle of the kizilkum desert. In its heyday, the area of the Aral Sea was 66000 square kilometers, almost equivalent to the land area of Sri Lanka. There are dozens of small lakes, swamps and wetlands in the tributary delta covering 550000 hectares. There used to be 1500 islands within one hectare. However, today’s Aral Sea has many problems The serious waste of water resources by the Soviet Union has declined by more than 90% compared with that in 1960. The “Aral Sea” no longer exists, but has become several “little Aral Sea”. For the sake of political achievements, the Aral Sea has dried up in a large area, the salinity of the lake water has increased, and the former ports have become inland cities.
There are more than 600 species of fish in the Aral Sea. The local fishermen once fished 40000 tons, accounting for 6 / 1 of the total catch of the former Soviet Union. By 1991, there were only more than 70 species left. Commercial fishing had ended in 1982. More than 95% of the marshes and wetlands had become deserts, and more than 50% of the delta lakes had dried up.
There is a large lake in the Aral Sea, which has become the north and South Aral Sea, and finally two small lakes. The Aral Sea has been seriously damaged by human beings, and the Revenge of nature has also come. The local climate has experienced extreme weather, and the exposed riverbed has a lot of salt, which has led to frequent sandstorms, salinization of farmland, and serious river pollution. It is important that it has endangered human health, according to the statistics For example, the incidence of cancer has increased by 3000% and the incidence of arthritis has increased by 6000%. The infant mortality rate is one of the highest in the world. It has also led to a sharp decline in biological species. By 2001, there were few fish left, and the number of birds has decreased from 173 to 38.
Seeing today’s Aral Sea, people have finally taken a series of measures to protect and save the Aral Sea. They have rebuilt the canal of the SYR River and built a dam to block the flow of the Aral Sea between the north and the south, so as to protect the Aral Sea. The Uzbek government has decided to open the gates of the river regularly and let some of the water flow into the South Aral Sea. I hope this series of measures will play a role in the Aral Sea, if there is no evidence It is predicted that the Aral Sea will disappear from the earth in 2020.
