Why do streams and rivers in many villages dry up after decades?

There are crystal clear rivers in the memory of rural children. When I was a child, I washed clothes, shoes, fish, shrimps and crabs in the river, and bathed in the river when it was hot. But now the memory is gone. There is no water in the stream, and there is a lot of silt and garbage in the original waterway. Why have most rivers dried up? Where is the water?

The supply of rainwater is insufficient, and the global temperature is rising, especially in rural areas, which brings together many springs. There is a saying: "A trickle makes a river." The depletion of water resources leads to more droughts, and dry weather leads to more water depletion, forming a vicious circle.

With more and more farmers entering the city, the surplus labor force in the village is getting less and less, and no one organizes cleaning. After a long time, the river will be blocked by weeds and sundries, and the silt in the river bed will also accumulate, so there is not much rain, so the river will become narrower and narrower and become very dry. Now in the countryside, many streams have been closed for more than ten years.

The development of industry needs a lot of water, and hardened water blocks the spring water. People born in rural areas know that there are springs in many small ditches and streams, and all of them flow out. But now, for the convenience of irrigation, many times, instead of weeding with industrial water, small ditches and streams are watered with cement. Ditches for dumping cement blocked many springs and streams, greatly reducing water sources. There is also industrial development, a lot of water and industrial pollution. Sometimes, some factories built in the suburbs directly discharge industrial wastewater into rivers for convenience, and the garbage is dumped there, making the rivers dirty. Sometimes saying that the river is "gone" is not really dry. Who can call it a "river" in the face of a stinking ditch floating with garbage and dead fish?

Start from the small things around us, take care of our mother river, don't throw things into the river easily, protect our river and protect our living environment. In particular, save water, make the earth full of vitality, make the environment picturesque and make life happier. Come along! Let the river return to childhood!

The biggest reason in mountainous areas is soil erosion. A large number of forests have been cut down and vegetation has been seriously damaged. The reason is that trees have not been replenished in time after being cut into timber, and a large number of rabbits have been abandoned. Second, farmers remove the original vegetable skins and plant cash crops, including fruit trees, seedlings, rabbits and so on. Although the sun has basically risen now, the soil moisture in the mountains has evaporated a lot. The water system of rabbits is dry and it rains, and a lot of loess floats to lower places, and the rain lasts for a long time. Even rabbits have mudslides and heavy rains.
