China's Pollution Crisis: Harming Its Own People

China's pollution problem has had a devastating impact on its citizens, causing serious health issues and even deaths. The country's rapid industrialization and urbanization have led to increased emissions of greenhouse gases, with coal being a major contributor. This has resulted in poor air quality, particularly in Chinese cities, where the annual average concentrations of inhalable particles, sulfur dioxide, and nitrogen dioxide exceed safe levels. The World Health Organization (WHO) has linked air pollution in China to approximately 300,000 premature deaths per year. In addition to respiratory and cardiovascular issues, cancer has become the leading cause of death in the country, according to the Chinese Ministry of Health. Water pollution is another significant concern, with many rivers and water sources contaminated, leading to digestive cancers and infectious diseases. The economic costs of pollution are also substantial, with environmental issues costing billions of dollars annually and affecting China's economic growth.

Air pollution's impact on public health

Air pollution in China has had a significant impact on the health of its citizens. In 2017, an estimated 1.24 million people died from exposure to air pollution in the People's Republic of China (PRC), with 30 million deaths attributed to air pollution since 2000. Air pollution is an important public health concern in China, with high levels of exposure to both ambient and household air pollution.

The main sources of air pollution in Chinese cities have been identified as coal combustion and motor-vehicle emissions. Outdoor air pollution is considered the biggest environmental challenge for public health in Chinese cities. Adverse health effects of outdoor air pollution in China include increases in respiratory symptoms, hospitalisation, and premature mortality.

Indoor air pollution in rural areas of China, caused by the use of coal and biomass fuels in stoves, has also been linked to adverse health effects, including lung cancer, acute respiratory infection, and chronic obstructive pulmonary disease.

The World Health Organization (WHO) has estimated that outdoor air pollution was associated with approximately 300,000 premature deaths per year in China, while indoor air pollution caused by solid fuel use in households was estimated to cause approximately 420,000 premature deaths annually.

Health effects of air pollution in China have been studied using a hierarchical linear model that combines pollution, socioeconomic, and psychosocial variables. These studies have found that higher education, income level, life satisfaction, and long-term marriage are associated with better health status among Chinese citizens.

The impact of air pollution on government health expenditure in China has also been analysed. It was found that industrial sulfur dioxide emissions, a representative air pollutant, had a significant impact on government health expenditure, with a q-value of 0.5283.

Overall, air pollution in China has had a significant impact on the health of its citizens, with increased mortality, morbidity, and healthcare costs attributed to both outdoor and indoor air pollution.

Water pollution and scarcity

Water scarcity and pollution are significant issues in China, and they have had a substantial impact on the country's citizens. Water scarcity in China is caused by several factors, including uneven distribution of water resources, rapid industrialization, urbanization, and climate change. The country's water resources are unevenly distributed, with the southern and eastern regions receiving abundant rainfall while the northern and western regions experience water scarcity. This disparity has led to flooding in some areas and droughts in others. China's rapid industrialization and urbanization have also put a strain on water resources, with increasing water demand for agricultural, industrial, and domestic use.

The effects of water scarcity and pollution are felt by Chinese citizens in various ways. One of the main consequences is the lack of access to clean drinking water. According to estimates, about 300 million people in China drink contaminated water daily, which has led to health issues such as diarrhea, cancer, stunted growth, and birth defects. The agricultural sector, which accounts for 70% of water use worldwide, is also affected by water scarcity and pollution. Inefficient irrigation methods and the use of agricultural chemicals contribute to water pollution and scarcity. Additionally, water scarcity has impacted energy production, as water is used for hydropower generation.

To address water scarcity and pollution issues, China has implemented various measures. The government has invested in water infrastructure development and increased regulations to protect water resources. One of the most well-known initiatives is the South-to-North Water Diversion Project, which aims to reroute water from water-abundant southern China to the water-scarce north. China has also explored technological solutions, such as desalination and water conservation programs. The country has also implemented policies and laws, such as the Water Pollution Prevention and Control Law and the Resource Tax Law, to reduce water usage, waste, and pollution.

Overall, water scarcity and pollution are complex issues in China that have affected the lives of its citizens. The country has taken steps to address these challenges, but the effectiveness of these measures remains to be seen.

Soil pollution

China's troubles with air and water pollution are well-known, but soil pollution has been less visible. However, it is no less of a problem, damaging health and livelihoods in villages across China. A recent investigation titled "The victims of China's soil pollution crisis" concluded that rapid industrialization has left a legacy of soil pollution.

The Chinese government has acknowledged the issue. A report released in April 2024 said that 16.1% of the country's soil was polluted. The figure for contaminated farmland is even higher, at 19.4%. The main contaminants are heavy metals such as cadmium, lead, nickel, and arsenic, among others.

The areas mainly affected include the country's industrial belt along the eastern coast, as well as inland provinces in central and western China. The main sources of this kind of pollution are industrial waste seeping from factories onto the soil and agricultural activities such as the application of fertilizers and the use of polluted water for irrigation.

The Chinese government has been accused of resisting media attempts to spotlight local cancer epidemics in the country's newly industrial areas. Indeed, the government previously refused to divulge information on soil pollution, terming it a "state secret". However, in February 2013, the Ministry of Environmental Protection (MEP) finally admitted that "cancer villages" existed in China. The number of such villages is estimated to be around 450 and is on the rise.

The problem is severe and urgent. Many polluting factories have been shut down in central and eastern parts of the country, but this is less true of western China, where there are thousands of toxic sites that need to be contained. Experts call for more government focus on crop safety, demanding that contaminated sites be taken out of the food production chain. Getting rid of the pollution involves the restoration of soil health, which is required to ensure food safety and people's health.

Impact on climate change

China's pollution problem has had a significant impact on its citizens, and the country now faces new challenges due to climate change.

As the world's top emitter of greenhouse gases, China's actions have a significant impact on global efforts to address climate change. Its carbon emissions and broader environmental degradation not only threaten the health and well-being of its citizens but also endanger economic growth and government legitimacy. China's carbon-intensive industries, rapid urbanization, and increasing number of vehicles on the road have all contributed to its high emissions.

China's pollution problem is closely linked to climate change, and the country is already experiencing its adverse effects. For example, northern China has been hit by an increased number of sandstorms due to desertification in Mongolia, which is driven by climate change. These sandstorms cause pollution levels to rise and pose a risk to public health.

Climate change is also expected to bring more frequent atmospheric stagnation to China, characterized by low wind speeds near the ground that hinder the dispersion of pollutants, leading to haze conditions over time. This phenomenon will make it more challenging for China to manage its air quality and could result in a further decline in air quality in the coming decades.

Additionally, climate change will likely lead to more frequent heatwaves in China, which will exacerbate ground-level ozone pollution. This "climate penalty" will have adverse health effects on hundreds of millions of people.

To address these challenges, China has implemented policies such as signing the 2015 Paris Agreement on climate and pledging to achieve carbon neutrality by 2060. However, following through on these commitments won't be easy, especially as the country struggles to balance economic growth and public discontent.

China's efforts to curb emissions and mitigate climate change are crucial not only for the health and well-being of its citizens but also for the global fight against climate change.

Impact on economic growth

China's pollution problem has had a significant impact on its economic growth, with the country facing a trade-off between pursuing economic development and addressing environmental concerns. Here are four to six paragraphs detailing the impact of pollution on China's economic growth:

Paragraph 1:

China's rapid industrialization and lax environmental oversight have led to various environmental issues, including air and water pollution, desertification, and soil degradation. These problems have subjected Chinese citizens to significant health risks and hindered the country's economic growth prospects. The Chinese government has acknowledged these challenges and implemented policies to improve the situation, but critics argue that these efforts have been inadequate.

Paragraph 2:

The country's economic growth targets have had a significant impact on the behavior of local governments, often resulting in a relaxation of environmental regulations and a blockage of industrial structure upgrades and technological innovations. This has led to a further increase in regional environmental pollution. Additionally, local governments often adopt a "riding a seesaw" strategy, prioritizing economic growth over environmental protection. As a result, China's economic growth has become heavily dependent on large inputs, inducing more serious environmental problems.

Paragraph 3:

The environmental Kuznets curve (EKC) theory suggests that there is an inverted U-shaped relationship between pollution and economic growth. According to this theory, as a country's income increases, its concern for environmental quality increases, leading to stricter environmental regulations and improved environmental quality. However, in the case of China, the EKC has not been consistently verified. Some studies indicate that most areas of the country are far from reaching the turning point of the curve, and the mechanism may differ from other countries.

Paragraph 4:

China's unique government institutions and policies play a significant role in environmental pollution research. The country's economic growth-focused official promotion evaluation system motivates local officials to prioritize economic performance, often at the expense of the local ecological environment. Fiscal decentralization, environmental regulations, and official promotion tournaments are among the factors influencing the impact of government behavior on pollution. Additionally, the relationship between economic growth targets and environmental pollution is complex and dynamic.

Paragraph 5:

China's pollution problem has had a substantial adverse effect on its regional economic growth. Air pollution, in particular, has been found to reduce labor productivity, cause a loss of human capital, and directly harm industries that rely on a clean environment, such as tourism and agriculture. The negative impact of air pollution on economic growth is stronger in the eastern region and provinces with smaller state-owned enterprise shares, lower governmental expenditures for public health services, and fewer medical resources.

Paragraph 6:

Addressing China's pollution problem is crucial not only for the country's environmental sustainability but also for its economic growth. By taking effective measures to reduce air pollution, China can expect to see significant economic benefits, especially in regions heavily affected by pollution. This includes an increase in the GDP growth rate and the expansion of the economy's scale. Additionally, improving air quality can enhance the competitiveness of the tourism industry and promote sustainable economic development.
