The Yangtze is the world's third-longest river and may be the world's most polluted river
The Yangtze River is Asia's longest river and the third-longest river in the world. It rises in the mountains of Qinghai province, on the Tibetan plateau, and flows 6,300km to the East China Sea at Shanghai. The river basin provides about half of all the fish eaten in China and two-thirds of the rice. It is also the largest source of fresh water in China, accounting for 40% of its total reserves.
The river is a lifeline to over 400 million people, but it is also one of the most polluted waterways in the world. The pollution in the Yangtze has multiplied as China's economy has developed, particularly from industries and agriculture, including large-scale fish and pig farming. More than 14 billion tons of liquid waste is discharged into the Yangtze each year, accounting for almost 42% of the country's total. This includes industrial sewage, ship waste, agricultural pesticides, and chemical fertilizers. Dangerous goods such as oil, toxic substances, fuel oil, liquefied gas, and gasoline also find their way into the river.
The pollution in the Yangtze has had disastrous consequences for wildlife. The river used to be home to a rich variety of flora and fauna, but many species are now dying out. The beloved Yangtze river dolphin, for example, is now believed to be extinct, with no sightings since 2002. Animals in the areas surrounding the river have been found with microplastics in their stomachs, slowly killing them.
The pollution is also a serious threat to human health. Nearly half of the people who depend on the Yangtze for drinking water have no safe water to drink. The number of cancers is increasing among residents who consume Yangtze water, with instances of stomach, throat, and liver-related cancers affecting residents at a rate two to three times China's national average.
There have been efforts to control and improve the situation. The central government has launched measures and regulations to tackle the pollution, and the supervision and management system of the sewage outfall into the Yangtze has been strengthened. However, the fight against pollution is still ongoing, and it will take a comprehensive approach to restore the Yangtze to its former health.

The river's pollution is caused by industrial sewage, ship waste, and agricultural pesticides
China's Yangtze River is considered the world's third-longest river and provides drinking water for over 400 million people. Unfortunately, it is also one of the most polluted waterways globally. The river's pollution is caused by a combination of factors, including industrial sewage, ship waste, and agricultural pesticides.
Industrial activities have significantly contributed to the Yangtze River's pollution. A large number of factories are situated along the river, especially in the middle and lower reaches. These factories have been known to discharge wastewater directly into the river, which has been identified as the leading cause of pollution. While measures have been implemented to control and reduce wastewater discharge, the river's water quality remains compromised.
Agricultural practices have also played a role in the river's pollution. The use of chemical fertilizers and pesticides in agriculture has led to eutrophication, resulting in excessive nitrogen and phosphorus levels in the water. This has caused algal blooms, such as blue-green algae in Taihu Lake, which can be harmful to aquatic life and reduce oxygen levels in the water. Additionally, agricultural runoff containing livestock waste has further contributed to the pollution.
Ships and boats navigating the Yangtze River also contribute to the pollution through the disposal of ship garbage and waste. Oil, toxic substances, fuel oil, liquefied gas, and gasoline are often discharged into the water, posing a significant threat to the health and safety of those who rely on the river.
The cumulative impact of these pollution sources has had devastating consequences for the environment and the people who depend on the Yangtze River. The river's water has become unsafe for drinking, with instances of stomach, throat, and liver-related cancers affecting residents at a much higher rate than the national average. Additionally, the rich flora and fauna that once thrived in and around the river have suffered, with species like the Yangtze river dolphin believed to be extinct.
Addressing the pollution in the Yangtze River is crucial, and efforts are being made to implement effective measures. However, the complex nature of the problem, involving multiple sources of pollution and the need for comprehensive treatment across different regions, presents a challenging task.

The pollution is endangering the 400 million people who rely on it for drinking water
The Yangtze River is the third-longest river in the world and is also one of the most polluted. It supports over 400 million people and accounts for 55% of the material that ends up in neighbouring seas and oceans. The pollution is endangering the 400 million people who rely on it for drinking water.
The river's pollution is having disastrous consequences for wildlife. Animals in the areas surrounding the river have been found with microplastics in their stomachs, slowly killing them. The Yangtze River dolphin, for example, is now believed to be extinct. The Chinese alligator, Chinese paddlefish, and Korean sturgeon are also under threat.
The pollution of the Yangtze River is primarily due to industrial sewage, ship waste, agricultural pesticides, and chemical fertilizers. Rapid industrialization and urbanization in China have transformed the environment, and the river has become a dumping ground for waste. More than 14 billion tons of liquid waste, including oil, toxic substances, fuel oil, liquefied gas, and gasoline, are discharged into the river each year. The construction of over 50,000 dams has also disrupted the natural flow of the river, affecting both wildlife and people.
The pollution is a significant health risk for the people who rely on the river for drinking water. The number of cancers is increasing among residents who drink Yangtze water, and instances of stomach, throat, and liver-related cancers have affected residents at a rate two to three times China's national average. According to a 2016 report, more than 80% of groundwater in China is unfit for drinking or daily use due to heavy contamination.
The Chinese government has recognized the severity of the problem and implemented measures and regulations to control and improve the situation. However, the fight against pollution is ongoing, and it will take time to restore the river's water quality to its previous state.

The WWF and HSBC Water Programme have made recommendations to partners in business and government about managing water use and reducing pollution
The Yangtze River in China is the third-longest river in the world and a source of sustenance for over 400 million people. However, it is also one of the most polluted waterways globally. The river basin contributes significantly to China's economy, with industries and agriculture flourishing in the region. Unfortunately, this economic activity has led to increased pollution in the Yangtze and its lakes, endangering the millions who depend on it.
Recognizing the urgency of the situation, the WWF and HSBC Water Programme have collaborated to address water management and pollution reduction in the Yangtze River Basin. They have provided recommendations to business and government partners, focusing on sustainable practices. One key recommendation is to ensure the proper release of water from the Three Gorges Dam, the world's largest hydropower station, to balance the needs of downstream communities and wildlife. The programme also promotes alternative livelihoods for fishermen to reduce overfishing and protect wildlife, such as the critically endangered Yangtze finless porpoise.
Additionally, the WWF and HSBC Water Programme support "nature schools" and assist local communities, farms, and fisheries in reducing their environmental impact on the Yangtze and its wetlands. They have also worked with hotels and mines to implement pollution control practices and protect vital wetlands. Their efforts extend beyond the Yangtze, as they have engaged in projects like the Wetland Watch Programme in Thailand, which involves volunteering and awareness activities related to watershed education and water quality monitoring.
Furthermore, the WWF and HSBC Water Programme have contributed to global strategic water management reviews in collaboration with the Global Water Initiative for Production (GIWP). They understand the importance of freshwater systems as a finite and valuable resource and aim to protect and restore them through their initiatives. One such initiative is the Pantanal project in Brazil, which focuses on improved watershed management, sustainable aquaculture and agriculture, and environmental flow releases. By working with various partners and communities, the WWF and HSBC Water Programme strive to make a tangible impact on water management and pollution reduction.
