The drought in Dongting Lake caused a large number of fish to be trapped and die. How to fight drought in extremely hot weather?

* * * With the struggle against dry weather, treated sewage can be used for agricultural irrigation to resist drought, and reuse systems can be developed in industry to reduce the use of water and electricity. In life, we can save water and fight drought. Drought weather is more like a natural situation, although it will bring a lot of harm, but compared with natural disasters such as floods and earthquakes, it will at least give people time to think of ways to deal with it. The hot weather in recent days has made many places in the south open the barbecue mode. When Mr. Li saw Dongting Lake a few years ago, he could associate it with Yueyang Tower. Now he went to Yueyang Tower and saw that the lake bed had become a grassland, without the artistic conception at that time. You can see that the water level in Dongting Lake has dropped rapidly, the water area has been reduced again and again, the lake has been covered with grass and the lake has disappeared. This shows how urgent the drought is.

First, agriculture can actively use recycled sewage to fight drought. In any case, people's lives will continue, and agriculture should be the most seriously affected under drought. Crops can't survive without water in farmland. In this case, the reclaimed sewage can be purified and used for farmland irrigation, at least to alleviate the drought in farmland. Under the hot weather, the aquaculture industry is not easy to do, so it can be properly stocked to solve the urgent need.

Second, industry can improve the water cycle to fight drought. The problem of lack of water and electricity under drought has long been highlighted. To solve the problem of industrial water use, we can only improve the recycling of water by scientific and technological means. Drought also leads to power shortage. In this case, we should place our hopes on new energy or wind power generation.

Third, in life, we can save water to fight drought. As an ordinary person, we can also do something to fight drought and form a good habit of saving water in our daily life. Remind your family to use the washing machine as little as possible. Washing clothes costs water and electricity. It can be replaced by hand washing, and domestic water can be reused.
