China's Pollution Problem: Who Cares?

China's environmental crisis, the result of decades of rapid industrialization, not only threatens the health and livelihoods of its 1.4 billion people but also the global fight against climate change. China is the world's leading annual emitter of greenhouse gases and mercury, and its carbon emissions threaten global efforts to mitigate climate change. The country's environmental degradation also endangers economic growth, public health, and government legitimacy. However, China has implemented policies to combat pollution, such as signing the 2015 Paris Agreement on climate and pledging to be carbon neutral by 2060. In addition, China has launched national air quality action plans, resulting in significant reductions in pollution levels and associated health risks. The country has also introduced aggressive afforestation and reforestation programs, such as the Great Green Wall, and has made efforts to reduce plastic pollution and improve waste management. While China has made progress in addressing its pollution problem, it still has work to do to achieve sustainability and improve the health and well-being of its citizens.

Water pollution

China's rivers and lakes have suffered profound water quality impairments due to economic development and industrialization. An investigation in 1980 revealed that agriculture, forestry, and husbandry accounted for about 88% of the country's total water consumption. A survey of 878 rivers in the early 1980s showed that 80% were polluted to some extent, and fish became extinct in more than 5% of the total river length. By 2000, the volume of wastewater produced had doubled since 1990, reaching almost 78 billion tons. This has led to dangerous levels of water pollution, with over half of China's population consuming drinking water contaminated with levels of animal and human excreta that exceed permissible limits.

The Lowy Institute estimates that 80-90% of groundwater in China is unsuitable for drinking due to toxic human and industrial waste dumping, farm fertilizers, and chemical runoff. This has rendered approximately 70% of rivers and lakes unsafe for human use, with eutrophication causing superabundant algae growth and depleting oxygen levels. China's rapid industrialization has resulted in increased soil pollution, threatening food safety and sustainable agriculture. An estimated 38,610 square miles of cultivated land have been polluted, impacting one-tenth of the country's arable land and causing annual losses of $2.57 billion.

The Chinese government has implemented measures to address water pollution, including the 2008 Law on the Prevention and Control of Water Pollution, which tightened regulations. The Total Amount of Pollutants Control Plan proposed in 2000, and the 13th 5-Year Comprehensive Work Plan from 2016 to 2020, set targets for reducing pollutant discharge. Additionally, the ban on free plastic bags in 2008 reduced plastic waste, and the Great Green Wall of China aims to combat desertification through large-scale tree planting. However, enforcement and the balance between economic growth and environmental protection remain challenges.

Air pollution

China's rapid industrialization and urbanization have led to a significant increase in air pollution levels, particularly in major cities. The country's reliance on coal-powered plants and coal-burning heating sources has been a major contributor to air pollution. Fine particulate matter (PM2.5) produced by these sources can affect people's health when levels are high, and this pollution can also cross borders into neighboring countries. In recognition of this problem, China has taken steps to reduce its coal consumption and retire older, less efficient coal plants, replacing them with more efficient facilities. Additionally, China has invested in renewable energy sources such as solar, wind, hydroelectric, and nuclear power, pledging billions of dollars towards these initiatives.

Despite these efforts, China's coal-powered industries continue to expand, and the country's energy consumption per capita still lags behind that of developed countries. Vehicle emissions are another significant contributor to air pollution, particularly in larger cities. According to China's Ministry of Ecology and Environment, vehicle emissions were responsible for about 45% of Beijing's air pollution in 2018 and nearly 30% in Shanghai.

To combat air pollution, the Chinese government has implemented various policies and programs. The Air Pollution Action Plan, released in 2013, helped improve air quality between 2013 and 2017, reducing PM2.5 levels significantly in Beijing and the Pearl River Delta. The government has also introduced aggressive afforestation and reforestation programs, planting billions of trees across multiple provinces. These initiatives have contributed to a decrease in pollution levels and associated health risks, with research suggesting that China's fight against air pollution has positively impacted the country's life expectancy.

China's efforts to tackle air pollution have had both domestic and international impacts. The nationwide air pollution reduction program has resulted in a decrease in transboundary air pollution, benefiting neighboring countries such as South Korea, which has experienced fewer deaths and emergency room visits related to air pollution. However, some critics question China's commitment to funding renewable energies, as investments in clean energy fell by 8% in 2019 compared to the previous year.

Soil contamination

China's environmental crisis, caused by decades of rapid industrialization, poses a threat to the health and livelihoods of its 1.4 billion people and the global fight against climate change. Soil contamination is one of the many environmental issues China is dealing with.

The State Environmental Protection Administration believes soil pollution to be a threat to the environment, food safety, and sustainable agriculture. China's immense population growth since the 1980s has resulted in increased soil pollution. About 38,610 square miles (100,000 square kilometers) of China's cultivated land has been polluted, with contaminated water being used to irrigate a further 31,500 square miles (21,670 square kilometers). The affected area accounts for one-tenth of China's cultivable land. An estimated 6 million tons of food grain are contaminated by heavy metals every year, causing direct losses of 29 billion yuan ($2.57 billion).

The problem in China is that the provinces with the highest rates of soil contamination are also the provinces with the largest amount of food production. This results in high contamination of food, with 13.86% of grain produced in China being affected by heavy metal contamination. Hunan Province represents the worst conditions: it is responsible for 32.1% of China's cadmium emissions, 20.6% of its arsenic emissions, 58.7% of its mercury emissions, and 24.6% of its lead emissions. While Hunan Province produces about 15% of the total rice output of the country, 13% of the total area of the province has been contaminated with waste and heavy metals from mines. In many areas, especially those closer to mines, agricultural production exceeds the official food safety standards.

To combat desertification, China has implemented the Great Green Wall of China project, which involves planting around 88 million acres of forests stretching about 3,000 miles (4,828 kilometers) and as wide as 900 miles (1,448 kilometers). The results have been satisfactory, with thousands of acres of moving dunes stabilized and the frequency of sandstorms nationwide falling by one-fifth between 2009 and 2014. However, some experts are skeptical, arguing that many of the trees planted as part of the project are not properly cared for and die.

Plastic pollution

China has been taking steps to address its plastic pollution problem, recognizing the environmental and health impacts of plastic waste. While the country has made efforts to reduce, reuse, and recycle plastic materials, the issue remains a significant challenge due to the sheer volume of plastic consumption and improper waste management practices.

The Chinese government has implemented various measures to tackle plastic pollution. For example, it has banned or restricted the use of certain single-use plastic items, such as thin plastic bags, and encouraged the use of reusable alternatives. Campaigns have been launched to raise public awareness about the importance of reducing plastic waste and proper waste sorting. Additionally, efforts have been made to improve recycling infrastructure and technologies, promoting the concept of a circular economy for plastics.

However, enforcement of these measures varies across regions, and the overall recycling rate for plastics remains low. A significant portion of plastic waste still ends up in landfills or is incinerated, contributing to air pollution and greenhouse gas emissions. Illegal dumping and the improper disposal of plastic waste also persist, particularly in rural areas or less developed regions, leading to soil and water contamination.

To further combat plastic pollution, China needs to continue enforcing and strengthening its waste management practices and recycling infrastructure. Investing in research and development for more sustainable alternatives to traditional plastics and promoting eco-friendly innovations can also help reduce the environmental footprint of plastic production and consumption. Educating the public about the importance of responsible plastic use and proper waste disposal is crucial, fostering a sense of environmental responsibility among citizens.

Additionally, collaboration between the government, industries, and communities is essential to effectively tackle plastic pollution. Policies and regulations need to be strictly enforced to ensure producers and consumers take responsibility for their plastic waste. By encouraging sustainable practices and promoting a circular economy for plastics, China can make significant strides in mitigating plastic pollution and creating a greener and more sustainable future.

Water shortages

Water scarcity is a pressing issue in China, with the country facing severe water stress due to shortages in water availability and quality. China's rapid economic growth, industrialization, and urbanization have resulted in widespread water pollution, further exacerbating the water scarcity problem. The country has the world's largest population, with 20% of the global population, but only 6% of the world's freshwater resources. This inequality in distribution is further compounded by the fact that 80% of China's water is concentrated in the south, while the north, which is the core of national development, faces more significant water scarcity.

The impact of water pollution on water scarcity is evident in China. Pollution from industrial wastewater, domestic sewage, agricultural pesticides, and manure has contaminated both surface and groundwater sources. In 2018, only 81.6% of rivers, 25% of lakes, 87.3% of reservoirs, and 23.9% of shallow groundwater met the criteria for drinking water supply sources. Continuous emissions from manufacturing, poorly treated sewage, industrial spills, and agricultural fertilizers have contributed to the deterioration of drinking water quality. According to China's State Environmental Protection Administration (SEPA) in 2006, 60% of the country's rivers were so polluted they could not be used as drinking water sources.

Climate change also plays a significant role in China's water scarcity crisis. Civilizations along the Yangtze and Yellow Rivers once relied on glacial meltwater from the Qinghai-Tibetan Plateau, but global warming has raised the temperature of this region, reducing the ice mass and the resulting glacial runoff. A 2018 Greenpeace study revealed that 82% of China's glaciers have retreated, and more than one-fifth of the ice cover has disappeared since the 1950s. As a result, glacial runoff into the Yangtze River alone has decreased by 13.9% since the 1990s, further reducing freshwater availability.

The Chinese government has implemented various measures to address water scarcity and pollution issues. In 2015, the State Council promulgated the Action Plan for Water Pollution Prevention and Control, clarifying local governments' responsibility for improving water quality. By 2017, major cities had achieved goals such as ensuring no large floating objects or garbage on river surfaces and no illegal sewage discharge. The South-North Water Transfer Project (SNWTP) is another initiative aimed at boosting water availability in dry regions, but it has faced challenges, including public discontent and the relocation of 330,000 people.

China's water scarcity and pollution issues have led to social and environmental challenges, including provincial water disputes, health risks, and the disappearance of local species. The country's water problems have also impacted its economic sustainability, with water-related issues potentially limiting China's sustainable economic and infrastructural development.
