topic
The beautiful li River and its amazing surrounding scenery is one of the most well.known tourist destinations in China's Guangxi Zhuang Autonomous Region. It attracts domestic and foreign visitors each year. However, its reputation as a topdestination has had negative effects on the river's water quality.
Previously, water quality in the Li River had suffered greatly from an increasing number of tourists, many of whom frequently threw garbage into the river. Many tour boatscontributed to the problem too. Kitchens on board were using lots of oil, which is usually thrown into the water. The growth in tourism also meant the local population rose rapidly, as well as the number of commercial and industrial enterprises. Water pollution increased, with more household and commercial waste ending up in the river.In order to feed more people, more chemicals were used to increase crop production . chemicals led to severe water quality issues, causing a decrease in the number of fish species. Local officials were concerned that the pollution was damaging the natural environment and felt that urgent steps should be taken to restore the river's original beauty.
We need to start a comprehensive initiative, with a number of measures that addressed theissues. The construction of waste water treatment facilities improved the water qualityand water conservation. The collection and transport of household waste was improved. Dozens of polluting enterprises were closed or moved. I think we should introduce new rules regarding tour boat routes and garbage disposal methods. Furthermore,the local authorities could begin to use the media to spread environmental awareness and encourage greater use of clean energy. The local government must set up strict regulations regarding further industrial development. At the same time, they started to camp outinspections regularly and fine tourist organisations for abuse. With these measures, I believe that the beauty of the li River will be preserved for generations to come.
