Several reasons for the deterioration of water quality in Hanjiang River

1. Due to the construction of water conservancy facilities, the water quantity in the upstream reaches is reduced, the water flow speed is slowed down, and the eutrophication of water bodies is more serious, leading to the wild growth of aquatic plants, the death of fish and the pollution of water quality.

2. Most citizens' awareness of saving water is still very poor, although there are many warning signs along the river, such as no swimming, no bathing and no washing clothes. But there are still many citizens watching it.

If you don't see it, you will still play in the river.

3. Many citizens have poor awareness of saving water, and many children are unreasonable and go into the river.

As a parent, you don't care if you throw garbage. In addition to water plants, there are a lot of floating white garbage in the water, which is very difficult to clean up.
