The impact of pollution on health and life expectancy
Air pollution in China is a significant issue, causing widespread environmental and health problems. The burning of fossil fuels, rapid population growth, and rapid economic growth have led to increased pollution and smog, which pose a threat to the health of Chinese citizens. According to the Chinese Ministry of Health, industrial pollution has made cancer the leading cause of death in the country. Ambient air pollution alone kills hundreds of thousands of citizens annually, with fine particles in the air causing respiratory and cardiovascular diseases. A study by the Health Effects Institute found that unhealthy levels of PM2.5 contributed to approximately 1.42 million premature deaths in China in 2019.
The impact of air pollution on health and life expectancy in China is profound. Studies have shown that long-term exposure to ambient PM2.5 pollution and household air pollution from solid fuels is associated with various chronic diseases, including stroke, ischaemic heart disease, chronic obstructive pulmonary disease (COPD), and lung cancer. The fine particles in polluted air penetrate deep into the lungs and cardiovascular system, causing severe health issues. In northern China, air pollution from burning fossil fuels, particularly coal, is reducing life expectancy by an average of 5.5 years.
Water pollution is also a pressing issue in China, with severe water shortages and contamination affecting both people and agriculture. An estimated 500 million people in China lack access to safe and clean drinking water, and contaminated water is used to irrigate cultivable land, leading to food grain contamination by heavy metals. Soil pollution is another concern, with solid waste covering or destroying vast areas of land, threatening food safety and sustainable agriculture.
The Chinese government has recognized the severity of the pollution problem and made commitments to address it. In 2014, China announced a "war against pollution," and since then, fine particulate air pollution (PM2.5) has been decreasing. The government has set air quality targets and implemented emission control measures, resulting in improvements in air quality. However, pollution levels still exceed the World Health Organization (WHO) guidelines, and air pollution continues to take a toll on public health and life expectancy.
The economic costs of air pollution are also significant, with studies estimating losses of up to $38 billion annually due to early deaths and lost food production. Socially, Chinese citizens have expressed frustration and protested against the public health hazard posed by air pollution, demanding better air quality and a healthier living environment.

The economic costs of pollution
China's economic transformation over the past four decades has made it the world's second-largest economy and a primary engine of global growth, contributing nearly 30% to worldwide economic expansion. However, this growth has come at a cost. China's development strategy has historically involved trading significant environmental resource consumption for high economic growth rates, resulting in environmental degradation and severe health costs.
The costs of environmental degradation in China have been continuously rising from 2004 to 2017, increasing from 511 billion yuan to 1,892 billion yuan, with an average annual growth rate of 10.6%. The annual average growth rate of atmospheric environmental degradation costs was 11.7%, while the annual cost growth rate of water environment degradation was 9.3%. Water pollution costs include human health loss, agricultural loss caused by sewage irrigation, additional treatment costs for polluted water, economic loss for urban residents, and water shortages.
Air pollution also carries significant economic costs. According to a 2018 report by Greenpeace and the Center for Research on Energy and Clean Air, air pollution led to economic costs of up to 6.6% of China's GDP. Another 2018 study from the Chinese University of Hong Kong estimates that RMB 267 billion ($38 billion) of revenue is lost annually due to early deaths and lost food production as a result of air pollution.
The health impacts of pollution also contribute to the economic costs. Studies have shown that environmental pollution exacerbates health disparities, reduces labor productivity, and constrains long-term economic sustainability. Air pollution, for example, is responsible for about 2 million deaths in China per year, including premature deaths caused by respiratory diseases, heart disease, lung cancer, and other cardiovascular diseases. The Chinese Ministry of Health reports that industrial pollution has made cancer the leading cause of death in China, and 500 million people in the country lack access to safe and clean drinking water.

Pollution and political trust
China's citizens have expressed frustration with the public health hazard posed by air pollution. Air pollution in China has been linked to a range of health issues, including respiratory and cardiovascular diseases, stroke, heart disease, lung cancer, and respiratory infections. It is also responsible for about 2 million deaths in China annually, with ambient air pollution accounting for more than 1 million of those deaths. A study by the Health Effects Institute found that unhealthy levels of PM2.5 led to approximately 1.42 million premature deaths in China in 2019.
The Chinese government has made efforts to address air pollution, such as implementing a ban on plastic bags in 2008 and committing to the 2015 Paris Agreement, where they pledged to peak carbon emissions by 2030 and increase the share of non-fossil fuels to 20% by 2030. China has also seen a decline in fine particulate air pollution (PM2.5) since 2014, with pollution levels down by 41% compared to 2013. However, air quality targets for 2021 were set higher than the 2020 average PM2.5 level, which may hinder progress in reducing pollution.
The link between pollution and political trust in China is complex. While there is some evidence that citizens who perceive the local air quality to be poor are less likely to trust county and provincial governments, air pollution does not seem to impact trust in the central government. This could be because political trust is a key component of political system support, which helps citizens accept the state's legitimacy to govern. Empirical studies have shown that trust contributes to regime support and legitimacy, while low trust can make it more difficult for leaders to succeed.
Protests over air quality have occurred in various Chinese cities, including Chengdu in 2016, Daqing in 2017, and Wuhan in 2019. These protests indicate a level of dissatisfaction with the government's handling of pollution issues. Additionally, a documentary on air pollution, "Under the Dome," went viral in China in 2015 before being censored, suggesting that Chinese citizens are concerned about the issue and seeking information.
Overall, while there is some evidence that pollution may impact trust in local and provincial governments in China, the relationship between pollution and political trust is complex and influenced by various factors. The Chinese government's efforts to address pollution have had mixed results, and air pollution remains a significant issue impacting the health and well-being of China's citizens.

Pollution reduction efforts
China's citizens have expressed their concerns about the pollution levels in their country through protests, with demonstrations taking place in Chengdu in 2016, Daqing in 2017, and Wuhan in 2019. In addition, a viral documentary titled "Under the Dome" by Chinese reporter Chai Jing highlighted the dangers of air pollution, receiving up to 200 million views before being censored.
China has made efforts to reduce pollution, with varying levels of success. Here are some of the key initiatives:
- In 2008, China implemented a ban on supermarkets, department stores, and shops giving out free plastic bags, encouraging the use of cloth bags instead. This ban contributed to a 10% reduction in plastic bags found in the garbage in the year following its implementation.
- China has invested in renewable energy technologies, becoming a global leader in the manufacturing of wind turbines and solar panels. Between 2020 and 2024, China's carbon intensity decreased by 7.9%.
- The Chinese government declared a war against pollution in 2014, allocating significant resources to combat pollution. This led to a notable decrease in particulate pollution, with Beijing experiencing a 55% decline in concentrations between 2013 and 2020.
- China has committed to international agreements to address climate change, such as the 2015 Paris Agreement, where they pledged to peak carbon emissions by 2030 and increase the share of non-fossil fuels to 20% by the same year.
- The Innovative Financing for Air Pollution Control Program, supported by the World Bank, has helped China reduce carbon dioxide emissions by 2.5 million tons annually.
- Beijing launched a four-color alert system in 2013, based on the air quality index (AQI), to indicate the level of pollution in the air. The system was revised in 2016 to standardize alert levels across multiple cities.

Pollution's impact on food safety
China's pollution problem has been well-documented, with air pollution from the burning of fossil fuels causing widespread environmental and health issues. Chinese citizens have expressed their concerns through protests and online documentaries, and the government has responded with various measures, such as implementing a four-color alert system for air quality and committing to carbon neutrality by 2060. However, the impact of pollution on food safety in China is also a significant concern.
The country's rapid population growth, industrialization, and urbanization have led to increased soil pollution, with an estimated 100,000 square kilometers of cultivated land contaminated. Water resources are also affected by severe shortages and pollution, with contaminated water being used for irrigation. This has direct economic impacts, with an estimated loss of US$2.57 billion due to contaminated food grains.
Heavy metals, such as mercury, have been found to accumulate in rice plants, posing risks to human health. Studies have also shown the impact of air pollution on food production and security, with fine particles in the air causing respiratory and cardiovascular diseases. The agricultural sector is a significant contributor to pollution, and inefficient agricultural practices further exacerbate the challenges to a stable food supply.
Food safety scandals, such as the adulteration of baby formula in 2008, have led to a perception that imports are safer than domestic products. The government has responded with improved oversight and regulation, and the evolution of pollution-induced food safety policies can be seen through four stages since 1974, with increasing stringency and collaboration between agricultural and environmental agencies. However, with China needing to feed nearly 20% of the global population, the task of ensuring food safety and security remains challenging.
Overall, pollution in China has had a significant impact on food safety, affecting soil, water, and air quality, and the government's response has evolved over time to address these issues, but the challenges remain vast.
