China's Pollution: A Global Crisis And Challenge

China's air pollution is a pressing issue that not only affects its citizens but also has far-reaching consequences for the world. As the world's leading emitter of greenhouse gases and mercury, China's air pollution poses a threat to global health and the economy. The fine particles released into the air from industrial activities, transportation, coal power plants, and household fuel usage can travel across borders, impacting the health and well-being of people in neighbouring countries. China's air pollution has been linked to increased mortality rates and respiratory issues in South Korea, with infants and the elderly being particularly vulnerable.

The effects of China's air pollution are also felt within its own borders, with approximately 2 million deaths attributed to it annually. The pollution has severe economic implications, with Greenpeace estimating that it costs China up to 6.6% of its GDP. Additionally, China's environmental degradation endangers economic growth, public health, and government legitimacy, as dissatisfaction among citizens grows.

To combat this issue, China has implemented policies such as the Airborne Pollution Prevention and Control Action Plan and made commitments to the 2015 Paris Agreement. However, the effectiveness of these measures is yet to be seen, and China continues to face the challenge of balancing economic growth with environmental and social welfare.

Air pollution increases global mortality risk

Air pollution is a combination of outdoor and indoor particulate matter and ozone. It is a risk factor for many of the leading causes of death, including heart disease, stroke, lower respiratory infections, lung cancer, diabetes, and chronic obstructive pulmonary disease (COPD).

Air pollution is one of the world's leading risk factors for death, contributing to one in ten deaths globally. In recent years, millions of deaths have been attributed to air pollution.

Air pollution is responsible for about 2 million deaths in China per year. Of those deaths, ambient air pollution alone caused more than 1 million deaths, while household air pollution from cooking with polluting fuels and technologies caused another million deaths in the same period in China.

The People's Republic of China is the world's leading annual emitter of greenhouse gases and mercury. This noxious air pollution threatens China's people, as well as global health and the world's economy. An estimated 1.24 million people died from exposure to air pollution in the PRC in 2017, according to a recent study in the medical journal The Lancet. Since 2000, the number of people who have died from air pollution in the PRC tops 30 million, according to New Scientist magazine.

China is the world's top emitter, producing more than a quarter of the world's annual greenhouse gas emissions, which contribute to climate change. It pledged to cut emissions under the Paris Agreement, reduce coal use, and invest in renewable energy. However, its Belt and Road Initiative still finances coal-fired power plants abroad.

Air pollution, water scarcity, and soil contamination remain threats to the health and livelihoods of China's people, increasing dissatisfaction with the government.

WHO data shows that almost all of the global population (99%) breathe air that exceeds WHO guideline limits and contains high levels of pollutants, with low- and middle-income countries suffering from the highest exposures.

Air pollution is closely linked to the earth's climate and ecosystems globally. Many of the drivers of air pollution (i.e. combustion of fossil fuels) are also sources of greenhouse gas emissions. Policies to reduce air pollution, therefore, offer a win-win strategy for both climate and health, lowering the burden of disease attributable to air pollution, as well as contributing to the near- and long-term mitigation of climate change.

From smog hanging over cities to smoke inside the home, air pollution poses a major threat to health and climate.

Ambient (outdoor) air pollution in both cities and rural areas is causing fine particulate matter which result in strokes, heart diseases, lung cancer, acute and chronic respiratory diseases. Additionally, around 2.4 billion people are exposed to dangerous levels of household air pollution, while using polluting open fires or simple stoves for cooking fuelled by kerosene, biomass (wood, animal dung and crop waste) and coal.

The combined effects of ambient air pollution and household air pollution are associated with 7 million premature deaths annually.

Both short and long-term exposure to ambient air pollution causes increased morbidity and excess mortality from multiple health endpoints, though the latter has comparatively much larger impacts on public health, being significant even at very low exposure levels. The chronic exposure to ambient PM2.5 (particulate matter with an aerodynamic diameter of less than 2.5 μm) and ozone are associated with reduced life expectancy, loss of healthy life years and excess mortality from cardiovascular as well as respiratory diseases. Recent studies have also implicated ambient PM2.5 exposure in adverse birth outcomes and mortality and morbidity from numerous other non-communicable diseases including diabetes, neurological disorders and cancers, among others.

In 2019, 74% of total deaths globally resulted from non-communicable diseases (NCD), a significant increase from 54% in 1990. Of all deaths from non-communicable diseases in 2019, about 20% may be attributed to environmental risk factors (including ambient air pollution, household air pollution, lead and radon exposure, extremes of temperature, unsafe water, sanitation, and handwashing). The exposure to ambient air pollution was found to be the single largest one (responsible for roughly 50% of the deaths from all environmental risk factors). More than 50% of these deaths from ambient air pollution exposure occur in China and South Asia, and about 20% of the total global air pollution-related deaths occur in high-income countries in Europe and North America. Given the now-extensive evidence of health risks even at very low concentrations of ambient PM2.5, this signifies the urgency of adequate air quality management also in countries with relatively low levels of air pollution exposure.

China's pollution affects global economic growth

China's pollution has a significant impact on global economic growth, affecting both the country's internal finances and the wider world. As the world's top emitter of greenhouse gases, China's actions have a profound influence on the planet.

Firstly, China's pollution has severe consequences for its citizens' health, which in turn impacts the economy. Air pollution is responsible for about 2 million deaths in China annually, with a further 1 million attributed to household air pollution from cooking with polluting fuels and technologies. This has a direct impact on the economy, with the World Health Organization (WHO) estimating that a 1% increase in PM2.5 leads to a 2.942% increase in household healthcare expenditure. The Chinese government also faces increased health service utilisation, with residents demanding better health services to cope with pollution-related illnesses.

The economic burden is further exacerbated by the indirect costs of pollution. For example, a study by Greenpeace and the Center for Research on Energy and Clean Air estimated that air pollution led to economic costs of up to 6.6% of China's GDP. Additionally, a study from the Chinese University of Hong Kong estimated that RMB 267 billion ($38 billion) is lost annually due to early deaths and reduced food production.

China's pollution also has a broader impact on the global economy. As a major trading nation, disruptions in China can have ripple effects worldwide. For instance, a 2018 report by Greenpeace and CREA highlighted that India's air pollution-related economic costs reached 5.4% of its GDP, while Bangladesh loses an estimated $6.5 billion annually due to pollution and environmental degradation in urban areas.

Furthermore, China's pollution affects other countries beyond its borders. A study by the University of Chicago and the U.S. Department of Energy's Argonne National Laboratory found that Chinese air pollution leads to increased deaths and emergency room visits in South Korea, particularly among infants and the elderly. This demonstrates the far-reaching consequences of China's pollution, which can impact the economies of other nations.

To address these issues, China has implemented various measures to reduce pollution and mitigate its impact on economic growth. These include the Airborne Pollution Prevention and Control Action Plan, which targets coal consumption, and the Thirteenth Five-Year Plan, which aims to lower PM2.5 levels and reduce coal's share of total energy consumption. However, the success of these initiatives remains to be seen, and China continues to face the challenge of balancing economic growth with environmental and social welfare.

China's pollution affects global health

China's pollution has a significant impact on global health. As the world's top emitter of greenhouse gases, China's carbon emissions contribute to global climate change, which affects the entire world. China's air pollution, in particular, has far-reaching consequences for global health.

Air pollution in China exposes people to fine particles that penetrate deep into the lungs and cardiovascular system, causing various diseases, including stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases, and respiratory infections. This air pollution is caused by industry, transportation, coal power plants, and household solid fuel usage.

The health effects of China's air pollution are evident in the high number of deaths attributed to it. According to various sources, air pollution causes about 1.24 million to 2 million deaths in China annually. A study in the medical journal *The Lancet* estimated that since 2000, more than 30 million people have died in China due to air pollution.

The impact of China's air pollution extends beyond its borders, affecting global health. Fine particulate matter and pollutants from China's air pollution can travel long distances and contribute to respiratory and cardiovascular issues worldwide.

China's efforts to curb air pollution have had some success, with a recent study showing an overall declining trend in household air pollution. However, China's rapid economic development and urbanization continue to present environmental challenges, and most of its population still lives in areas with air pollution levels above the World Health Organization's guidelines.

To protect global health, sustainable development policies must be implemented and enforced to reduce the impact of China's air pollution on the world.

China's pollution affects its own economy

China's pollution has a significant impact on its economy, threatening economic growth, public health, and government legitimacy. Air pollution, water scarcity, and soil contamination are among the most pressing issues, with air pollution contributing to an estimated 2 million deaths in China annually. This has a direct impact on the economy, with environmental issues costing the country up to 10% of its GDP.

China's rapid industrialization has resulted in it becoming the world's top emitter of greenhouse gases, producing more than a quarter of the annual global emissions. This has led to notoriously poor air quality, with fine particles from industry, transportation, coal power plants, and household fuel usage penetrating deep into the lungs and cardiovascular system of those exposed.

The Chinese government has attempted to address these issues, signing the Paris Agreement and pledging carbon neutrality by 2060. However, the country still faces challenges in maintaining economic growth while reducing emissions, with coal making up nearly two-thirds of its energy consumption.

The impact of pollution on China's economy is complex and far-reaching, affecting multiple sectors and industries. It has been linked to a loss of human capital, as high-skilled laborers may choose to leave polluted areas, and it has direct consequences for health and productivity, with air pollution contributing to respiratory diseases, cardiovascular problems, and cognitive impairment.

Additionally, certain industries, such as tourism and agriculture, are heavily impacted by poor air quality. The development of the tourism industry, for example, is hindered as good environmental quality is an essential characteristic of attractive destinations. Similarly, agriculture suffers losses due to air pollution, with crop yields and the diversification of wild species being adversely affected.

Overall, China's pollution has a significant negative impact on its economy, and addressing these issues is crucial for the country's sustainable development and the well-being of its citizens.

China's pollution affects its citizens' health

China's pollution has a detrimental impact on the health of its citizens. Air pollution in China is a major issue, with smog becoming increasingly frequent and severe in many cities. The country's rapid economic development has come at the cost of environmental degradation, with outdoor and indoor air pollution, water shortages and pollution, desertification, and soil contamination all posing significant health risks to Chinese residents.

Air pollution is the biggest environmental challenge to public health in Chinese cities. The source of air pollution has shifted from coal combustion to a mixture of coal combustion and vehicle emissions. The annual average concentrations of inhalable particles, sulfur dioxide, and nitrogen dioxide—the three criteria pollutants in China—were 89 μg/m3, 48 μg/m3, and 34 μg/m3, respectively, in 113 medium to large Chinese cities. Many studies have documented the adverse health effects of outdoor air pollution in China, including increases in respiratory symptoms, hospitalization, and premature mortality. The World Health Organization (WHO) estimated that outdoor air pollution was associated with approximately 300,000 premature deaths per year in China, with similar estimates from Chinese scientists.

In addition to outdoor air pollution, indoor air pollution from the use of solid fuels in stoves is also a significant health concern, particularly in rural areas of China. The World Health Organization (WHO) estimated that solid fuel use in Chinese households causes approximately 420,000 premature deaths annually. Water pollution is another serious health issue, especially in rural areas, where two-thirds of the population does not have access to piped water. Exposure to contaminated drinking water has been linked to increasing rates of digestive cancers and infectious diseases such as hepatitis and cholera.

Other environmental health problems in China include climate change, the disposal and treatment of electronic waste, and heavy metal pollution in the soil. China is one of the countries most vulnerable to the adverse effects of climate change, and pollution from heavy metals such as lead, mercury, chromium, cadmium, and arsenic poses a serious threat to the health of local citizens.

The Chinese government has recognized the seriousness of the country's environmental and health issues and has committed to improving the situation. The "Healthy China 2030 Plan" emphasizes the importance of managing health-related environmental problems. China has also pledged to achieve carbon neutrality by 2060 and has made efforts to reduce emissions and improve air quality. However, air pollution continues to pose a significant risk to the health of Chinese citizens, and more sustainable development policies are needed to address this challenge effectively.
