China's Pollution Crisis: Why It's So Bad

China's air pollution is a well-known issue with complex causes and severe consequences. The country's rapid industrialization, dense population, and reliance on coal power have contributed significantly to poor air quality. While China has implemented policies to reduce pollution, such as banning plastic bags and emphasizing clean energy, it continues to face challenges in enforcing environmental regulations and reducing the health and environmental impacts of pollution. The pollution in China not only affects its own citizens but also has transboundary effects on neighboring countries, underscoring the urgency of addressing this issue.

Industrialisation and population growth

China's industrialisation and economic boom since the late 1970s have contributed to record levels of air and water pollution. During this period, China's GDP grew at an average annual rate of 10% for four decades, lifting 800 million people out of poverty. This rapid industrial expansion has resulted in increased air pollution, with coal-fired power plants being a significant contributor. China's heavy reliance on coal power, a cheap but "dirty" energy source, has had detrimental effects on the environment.

The dense population and high population density in China also mean that more pollution occurs in a smaller area. The immense population growth in China since the 1980s has resulted in increased soil pollution. The State Environmental Protection Administration believes this poses a threat to the environment, food safety, and sustainable agriculture. China's cultivated land has been polluted, with contaminated water used for irrigation, and solid waste covering or destroying arable land.

Furthermore, China's industrialisation has resulted in increased water pollution. As much as 90% of the country's groundwater is contaminated by toxic human and industrial waste, as well as farm fertilisers, rendering many rivers and lakes unsafe for human use. The serious contamination of China's waterways by industrial discharges has made cancer the country's leading cause of death, according to the Chinese Ministry of Health.

In addition to industrialisation and population growth, China's lax environmental regulations have been cited as a contributing factor to its pollution levels. While the country has implemented policies to reduce pollution, such as banning the importation of electronic waste and encouraging the use of cloth bags instead of plastic, the enforcement and effectiveness of these measures have been questioned. China's recent emphasis on clean energy and investment in renewable technologies indicate a growing recognition of the need to address pollution and its transboundary impacts.

Lax environmental regulations

China's rapid industrialization and high population density have resulted in severe pollution, which has been exacerbated by lax environmental regulations. While China has made efforts to address pollution, such as banning plastic bags and implementing some environmental laws, the enforcement of these regulations has been inconsistent and ineffective.

China's industrialization has resulted in increased air pollution, water pollution, and soil pollution. The burning of coal, in particular, has contributed significantly to air pollution, with coal-fired power plants being a major source of emissions. China's population density further concentrates pollution in smaller areas, intensifying its impact.

In addition, the Chinese government's response to environmental issues has been criticized as inadequate and slow. While the government has implemented some environmental policies and regulations, such as the establishment of the Ministry of Environmental Protection, corruption and a lack of enforcement have hindered their effectiveness.

Furthermore, China's rapid economic expansion and relaxed environmental oversight have led to a number of ecological problems. While the government has undertaken measures to curb pollution due to public pressure, the impact of these efforts is not yet clear.

To summarize, China's pollution is a complex issue resulting from a combination of rapid industrialization, high population density, and lax environmental regulations at both the national and local levels. While efforts to address pollution have been made, stronger enforcement and more effective policies are needed to mitigate the severe environmental and health impacts of pollution in China.

Heavy reliance on coal power

China's rapid industrialization and economic boom since the late 1970s have contributed significantly to its air pollution crisis. During this period, China's GDP grew at an average annual rate of 10%, lifting 800 million people out of poverty. However, this rapid industrialization has had a severe environmental impact, with air and water pollution reaching record levels.

One of the critical factors contributing to China's pollution problem is the country's heavy reliance on coal power. Coal is a significant source of energy for China, and it is cheap and abundant. When China embarked on its industrialization drive, it depended heavily on coal-fired power plants to fuel its economic growth. Coal is considered the "'dirtiest'" type of power, and the large number of coal-fired power plants, coupled with the older coal-fired houses, have led to high levels of air pollution. The combustion of coal releases fine particulate matter (PM2.5) into the atmosphere, which can have detrimental effects on human health and the environment.

The issue of coal pollution is further exacerbated by China's high population density. With a vast population in a relatively small area, the concentration of coal-fired power plants and coal-burning households in certain regions intensifies the pollution problem. The dense population means more pollution is occurring in a smaller area, and the emissions from coal combustion affect a large number of people.

Moreover, China's industrialization has been accompanied by lax environmental regulations. Unlike the United States, which implemented urbanization rules and emission regulations during its industrialization process, China has had fewer restrictions on pollution from factories and industries. This lack of stringent regulations has contributed to the unchecked release of pollutants into the atmosphere.

Recognizing the severity of the problem, the Chinese government has started to prioritize fighting pollution. President Xi Jinping has labeled it as one of China's "three tough battles," alongside reducing poverty and improving financial stability. Recent years have seen a strong emphasis on clean energy, with investments in wind, solar, nuclear, and offshore wind power. Additionally, smart cities like Beijing and Nanjing are adopting renewable energy sources and smart technologies to reduce pollution from industries and traffic. These efforts are showing positive results, with China's war on pollution policies leading to a decrease in transboundary air pollution and improved air quality in neighboring countries.

Poor waste disposal

China's waste disposal problem is a complex issue with various factors contributing to its severity. Firstly, China's rapid industrialization and population growth have led to an increase in waste generation. The country's focus on industrialization, particularly its heavy reliance on coal power, has resulted in significant environmental and health problems. The immense population growth in China since the 1980s has also resulted in increased soil pollution, with an estimated 38,610 square miles of cultivated land being contaminated.

Secondly, China's waste management infrastructure has struggled to keep up with the increasing waste volumes. While the country has implemented measures such as the 2017 waste import ban and the "Green Fence" policy, the disposal of waste is still dominated by landfills. China had 654 landfill sites in 2017, and landfill space is reducing rapidly, leading to concerns about the environmental and health impacts of waste disposal.

Thirdly, China's recycling industry is facing challenges. While the country has introduced policies to encourage recycling, such as the “No Chopsticks” option on food delivery apps, the recycling rate remains unclear. Construction and Demolition Waste (CDW) is a significant issue, with only 5% of CDW being reused or recycled. The lack of segregation between organic and dry waste streams is also a barrier to creating more value from recyclables.

Moreover, China's waste disposal problem is not limited to domestic waste. The country has been a major importer of electronic waste and plastic rubbish from other countries, contributing to the overall waste volume and further straining the waste management system.

Finally, social and behavioral factors play a role in China's waste disposal challenges. While there are initiatives to encourage proper waste disposal and recycling, such as the XiaoHuangGou (XHG) smart trash bins, cultural and habitual practices can hinder progress. For example, the concept of "white pollution," referring to the proliferation of white plastic bags and light-colored waste in the mid-1990s, indicates a societal awareness of waste issues. However, the effectiveness of policies and individual efforts can be limited by insufficient enforcement and fraud.

Water pollution

China's rapid industrialization, economic growth, and urbanization have resulted in widespread water pollution. The country's rivers have suffered profound water quality impairments due to the pressure of economic development since China's Reform and Opening-up in 1978. Water pollution in China affects the health of its citizens, with approximately 700 million people—over half the population—consuming drinking water contaminated with levels of animal and human excreta that exceed maximum permissible levels by up to 86% in rural areas and 28% in urban areas. The World Bank stated in a 1997 report that "hundreds of thousands of premature deaths and incidents of serious respiratory illness have been caused by exposure to industrial air pollution." The Chinese Ministry of Health has also acknowledged that industrial pollution has made cancer the leading cause of death in China.

China's unprecedented geoengineering projects, such as moving water from the south to the north, are now endangering water resources downstream from Tibet and the Himalayas. The iconic Yellow River, a vital water source for southern China, has frequently run dry before reaching the Yellow Sea since 1997. This has resulted in a major cause of 40 billion cubic meters of water shortage in China annually.

The country's rapid industrialization has also resulted in the contamination of land and water. 38,610 square miles (100,000 km2) of China's cultivated land have been polluted, with contaminated water being used to irrigate a further 31.5 million square miles (21,670 km2). The agricultural sector is a significant source of waste, with Chinese farms generating more pollution than factories. The increased use of water for irrigation, chemicals to promote crop growth, and the introduction of advanced seeds in the last three decades have contributed to water pollution.

Furthermore, the consistent choice of Beijing's leadership to prioritize economic growth over environmental health has led to dangerous levels of water pollution. The Lowy Institute estimates that 80–90% of groundwater in China is unsuitable for drinking, and 50% is too polluted even for agricultural use. China's huge increase in the use of water for irrigation, as well as the introduction of chemicals and mechanical power to promote crop growth, have contributed to water pollution.

However, there have been some improvements in water quality in China. From 2003 to 2017, inland water quality across China improved or was maintained at favorable levels nationwide due to reductions in nutrient concentrations. In 2000, the Chinese government proposed the Total Amount of Pollutants Control Plan, taking COD as one of the control indexes of 12 major pollutants, which has achieved remarkable results.
