Air pollution kills 2 million people in China annually
Air pollution is a pressing issue in China, causing approximately 2 million deaths per year. The problem has become so severe that it poses not only a significant burden on the Chinese public but also a challenge to the ruling Communist Party.
The sources of air pollution in China are diverse, with industry, transportation, coal power plants, and household solid fuel usage being major contributors. Fine particles in the polluted air can penetrate deep into the lungs and cardiovascular system, causing serious health issues such as stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases, and respiratory infections. According to the World Bank, cities like Tianjin, Chongqing, and Shenyang had the highest levels of particulate matter in 2004.
China has taken some steps to address the problem. For instance, in 2019, several heavily populated areas, including Beijing, Shanghai, and Tianjin, began enforcing stricter motor vehicle emissions standards, requiring vehicles to have better exhaust gas filtering systems. Additionally, the government announced a plan in 2018 to replace coal-burning heaters with natural gas and electric heating systems in 1.2 million homes. However, this policy was reversed due to a short supply of natural gas.
Despite some efforts, air pollution in China remains a critical issue. In 2017, the entire population of China lived in areas with air pollution levels exceeding the WHO Air Quality Guideline, and the economic costs are also significant, with air pollution costing the Chinese economy an estimated 267 billion yuan in 2018.
The impact of air pollution in China is not limited to health and economic consequences. It also affects social aspects, as many Chinese citizens have expressed frustration over the public health hazard posed by air pollution. This frustration has been reflected in works like the viral documentary "Under the Dome" by Chinese reporter Chai Jing, which highlighted the severity of the issue.

Water pollution affects 500 million Chinese people
China's rapid economic growth, industrialization, and urbanization have resulted in severe water pollution. Inadequate investment in basic water supply and treatment infrastructure has led to widespread water contamination. Over 500 million people in China lack access to safe and clean drinking water, with rural areas being the worst affected. The water consumed by approximately 700 million people, more than half of China's population, is contaminated with animal and human excreta, exceeding maximum permissible levels.
The dramatic economic development in China has had significant environmental repercussions, particularly regarding water pollution. Increasing volumes of untreated wastewater from households, industry, and agricultural runoff have severely polluted the aquatic environment. China's water scarcity is further exacerbated by this pollution, with the available renewable freshwater failing to meet the demands of the vast population. North China suffers from water scarcity due to insufficient quantity and inadequate quality, while South China experiences seasonal water scarcity.
The Chinese government has recognized the urgency of addressing water pollution and has implemented various measures. In 2015, the State Council issued the Water Pollution Prevention and Control Action Plan, setting targets for improving water quality by 2030. The National People's Congress also passed revisions to the Water Pollution Prevention and Control Law in 2018, introducing a system of "river chiefs" and "lake chiefs" to hold local officials accountable for tackling specific water bodies' pollution. These efforts reflect China's commitment to mitigating water pollution and safeguarding its water resources.
Despite these efforts, water pollution remains a critical challenge. Beijing, for instance, has made notable commitments to reducing water pollution, but significant environmental and public health risks persist. More than 80% of China's water supply comes from surface water sources like rivers and lakes, many of which are severely polluted. In 2018, the Ministry of Ecology and Environment reported that 6.9% of China's surface water was "Below Grade V" quality, rendering it unfit for any use. The pressure on water supplies due to increasing demand has further compounded scarcity issues, outpacing the development of waste-management infrastructure.
Groundwater pollution, which is more challenging to remediate than surface water pollution, remains a persistent issue. While China has made considerable investments in improving access to water, urbanization and climate change continue to strain water resources. The aging water treatment infrastructure in even the most developed cities prompts many residents to boil and filter tap water due to concerns about inadequate treatment. As China continues to urbanize and its economy matures, leaders must prioritize resolving water security challenges to sustain the country's economic and social development.

China's pollution affects neighbouring countries
China's pollution problem is well-documented, with the country facing issues of water and air pollution, as well as the negative health impacts on its citizens. However, China's pollution does not only affect China; it also has significant impacts on its neighbouring countries.
South Korea and Japan, China's immediate neighbours, have expressed concern about the effects of China's pollution on their air, water, and soil quality. In 2013, South Korean media began referring to the smog coming from China as "air raids", and a Japanese study that same year found that air pollution from China was responsible for high levels of mercury deposition on Mount Fuji. The westerly winds carry China's air pollution across the East China Sea to Japan and South Korea, and research has shown that the northwest region of South Korea has much higher air pollution than the southeast, with up to 300 fewer deaths per million people per year in the south. This has resulted in an annual savings of over $2.6 billion for South Korea.
China's pollution has also been found to spread internationally, with sulfur dioxide and nitrogen oxides falling as acid rain on Seoul and Tokyo and even reaching Los Angeles in the United States. The United States is the world's second-largest emitter of greenhouse gases, and while it has made strides in cleaning its air, it is still impacted by China's pollution.
China has recognised the severity of its pollution problem and has implemented policies to address it, such as banning plastic bags and targeting vehicle emissions. These "war on pollution" policies have had positive effects on neighbouring countries, resulting in less transboundary air pollution and improved air quality in these nations.

China's plastic waste is a major contributor to ocean pollution
China has long been plagued by plastic pollution, along with severe air pollution. China is the world's largest plastic producer and exporter of single-use and virgin plastics, and until 2018, it was the largest importer of plastic as well. In 2020, China produced about 60 million tonnes of plastic waste, of which only 16 million tonnes were recycled. On average, only about 17% of the plastic used in China is recycled.
China has taken some steps to address its plastic pollution problem. In 2008, a ban was implemented on supermarkets, department stores, and shops giving out free plastic bags, and the production, sale, and use of ultra-thin plastic bags were prohibited. In 2021, China produced 80.1 million tons of plastic, and the country has implemented the "14th Five-Year Plan" Action Plan for Plastic Pollution Control, which aims to effectively control the leakage of plastic waste into the natural environment by 2025.
Despite these efforts, China's plastic waste continues to contribute significantly to ocean pollution. The country's import ban on plastic waste has shifted the burden of waste management to other poorer countries, and the agricultural sector, which generates more pollution than factories, remains a significant source of plastic pollution. China's plastic pollution has severe consequences for marine life, with plastics breaking down into microplastics that are ingested by marine organisms and enter the food chain.

China's pollution is threatening thousands of plant and animal species
China's pollution problem is a well-known issue that has gained international attention. The country's rapid industrialisation and immense population growth have led to various forms of pollution, causing widespread environmental degradation and threatening the survival of thousands of plant and animal species.
One of the most pressing issues is water pollution. For decades, factories discharged wastewater into lakes and rivers due to poor environmental regulations and enforcement. This has contaminated water sources, damaged habitats, and threatened the survival of aquatic species. The construction of the Three Gorges Dam, for example, permanently altered the Yangtze's landscape, pushing the already-endangered baiji dolphin towards functional extinction. Additionally, China's position as the world's largest producer and consumer of plastics has resulted in significant plastic waste pollution, with a substantial amount ending up in oceans and waterways, further threatening aquatic life.
Air pollution in China is another critical concern. The country's power plants and coal-burning heaters contribute significantly to high levels of particulate matter (PM2.5) in the air. These fine particles can cause asthma, bronchitis, and acute and chronic respiratory issues, leading to premature deaths. The health impacts of air pollution have been severe, with studies estimating that unhealthy levels of PM2.5 caused approximately 1.42 million premature deaths in China in 2019.
Soil pollution is also a significant issue in China, threatening plant species and agricultural sustainability. The State Environmental Protection Administration considers it a threat to the environment, food safety, and sustainable agriculture. Contaminated water has been used to irrigate cultivated land, leading to heavy metal pollution in food grains and significant economic losses.
Furthermore, China's participation in international projects has raised concerns about its environmental impact beyond its borders. Chinese-backed projects on several continents have been accused of negatively affecting water quality, polluting land, and spoiling fragile ecosystems. The World Wildlife Fund (WWF) has warned that some planned Chinese infrastructure projects could adversely affect critical biodiversity sites and the ranges of threatened species.
While China has taken steps to address some of these issues, such as implementing bans on plastic bags and imports of electronic waste, experts argue that more needs to be done to protect the country's biodiversity and reduce pollution's impact on plant and animal species.
