REDUCING WATER POLLUTION IN THE LI RIVER

The beautiful Li River and its amazing surrounding scenery is one of the most well-known tourist destinations in Chinas Guangxi Zhuang Autonomous Region. It attracts millions of domestic and foreign visitors each year. However, its reputation as a top destination has had negative effects on the river’s water quality. This report looks at the problem of water pollution and some actions that have been taken to deal with it.

Previously, water quality in the Li River had suffered greatly from an increasing volume of tourists, many of whom frequently threw garbage into the river. Many tour boats contributed to the problem too. Kitchens on board were using lots of oil. which was often 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 levels 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. These 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 rivers original beauty

A comprehensive initiative was started, with a number of measures that addressed the issues. The construction of waste water treatment facilities improved the water quality and water conservation. The collection and transport of household waste was also improved. Dozens of polluting enterprises were closed or moved. The local government set up strict regulations regarding further industrial development. New rules were also introduced regarding tour boat routes and garbage disposal methods. Furthermore, the local authorities began to use the media to spread environmental awareness and encourage greater use of clean energy. At the same time, they started to carry out inspections regularly and fine tourist organisations for abuses. With these measures, it is believed that the beauty of the Li River will be preserved for generations to come.

In addition, the ambitious “Water Ten Plan” is also now tackling water pollution across the country. Other initiatives, such as the “River Chief System”, hold senior officials responsible for reducing water pollution. With such campaigns in effect, Chinas waterways are heading towards a clean and sustainable future.

There has been a very serious decline in the numbers of shallow-water fish as a result of overfishing. People still want to eat fish, so the fishing industry must look at other sources, especially the deep waters of the Atlantic. 【小题1】.

Conservation measures will have to be put in place if these deep-sea fish are to survive. Research on five such species shows that numbers have declined by between 87 percent and 98 percent. 【小题2】 Many species could well disappear if the present trend continues. These are species that have been swimming in our oceans for hundreds of millions of years.

The problem is emphasised by the fact that the decline in numbers happened in less than twenty years. Deep-sea fish take a long time to reproduce and normally live for many years.

【小题3】 The average size of such fish also declined, with one species showing a 57 percent decline in average size. This is of particular concern, as large fish tend to produce more offspring than small ones.

None of these facts has been taken into account by the fishing industry. The deep-sea species have been caught as if they were the fast-breeding fish like sardine and herring. 【小题4】

The damage done by overfishing goes beyond the sea environment. Millions of people make a living in the fishing industry. 【小题5】 Measures must be taken to not only conserve ecosystems, but also sustain livelihoods and ensure food security.

There are two distinctive types of electric buses making their way along Nanjing Xi Lu, one of Shanghai’s busiest roads. The first is a fleet of blue trolleybuses that serve bus route number 20, a line set up by a British-run transport company in 1928. They use poles to receive electricity from wires overhead and have kept the route running in this way for nearly a century. But while the historic electric buses are a reminder of Europe’s past technological innovation, the new buses traveling alongside them are symbols of China’s contemporary net-zero ambition. These modern electric buses powered by lithium batteries (锂电池) , were introduced in Shanghai in 2014. They offer a smoother ride, especially during starts and stops. Widely used across China, these buses are key to the country’s EV transition and are influencing the global shift towards green transportation.

The most recent data available shows that China in 2018 was still the second largest source of carbon dioxide emissions in the global transport sector, responsible for 11%, and behind only the United States, which accounted for 21%. After around two decades of government support, China now boasts the world’s largest market for e-buses, making up more than 95% of global stock. At the end of 2022, China’s Ministry of Transport announced that more than three-quarters (77% or 542, 600) of all urban buses in the country were new energy vehicles. The speed of this transition was remarkable.

So far, however, the Chinese cities with the most successful e-bus introduction — such as Shenzhen, Beijing and Shanghai — all have moderate weather and are relatively flat. To take its e-bus campaign to the next level, China faces challenges. For one thing, it is difficult to bring fleets to cities such as Hong Kong, which — like London — have double-deckers. These two-storeyed vehicles are “very hard” to electrify, because they are heavier, use more energy, and so need bigger batteries, reducing the number of passengers they can carry. Cold weather is a problem, too, as it can make a battery’s charging time longer and its range shorter. The reason China has not achieved 100% electrification for its buses is its northern regions, which have cold winters, says Xue Lulu, a transportation expert at the World Resources Institute China.
