Through Industrialisation, Environmental law and Climate change

The Chinese government has acknowledged the problems and made various responses, resulting in some improvements, but western media has criticized the actions as inadequate. In recent years, there has been increased citizens' activism against government decisions that are perceived as environmentally damaging, and a retired government official claimed that the year of 2012 saw over 50,000 environmental protests in China.

Since the 2010s, the government has given greater attention to environmental protection through policy actions such as the signing of the Paris climate accord, the 13th Five-Year Plan and the 2015 Environmental Protection Law reform From 2006 to 2017, sulphur dioxide levels in China were reduced by 70 percent, and air pollution has decreased from 2013 to 2018 In 2017, investments in renewable energy amounted to US$279.8 billion worldwide, with China accounting for US$126.6 billion or 45% of the global investments. China has since become the world's largest investor, producer and consumer of renewable energy worldwide, manufacturing state-of-the-art solar panels, wind turbines and hydroelectric energy facilities as well as becoming the world's largest producer of electric cars and buses.

From an international perspective, China is a party to most of the major treaties meant to address environmental issues. This includes the Antarctic-Environmental Protocol, the Antarctic Treaty, the Convention on Biological Diversity, the Climate Change treaty, the United Nations Convention to Combat Desertification, the Endangered Species treaty, the Hazardous Wastes treaty, the Law of the Sea, the International Tropical Timber Agreements of 1983 and 1994, the International Convention for the Regulation of Whaling, and agreements on Marine Dumping, Ozone Layer Protection, Ship Pollution, and Wetlands protection. China has signed, but not ratified, the Kyoto Protocol (but is not yet required to reduce its carbon emission under the agreement, as is India) and the Nuclear Test Ban treaty.

Environmental problems

Background

Before the 1949 founding of the People's Republic of China, the environment was degraded. Beginning in the 1500s, farmers cleared upland land to increase agricultural acreage to plant crops, contributing to hundreds of years of deforestation. Erosion from denuded hillsides contributed to chronic flooding and resulted in sediment clogging waterways. The intensive farming systems of China had caused progressive loss of soil nutrients in the nineteenth and twentieth centuries. Polders encroached on lakes and wetlands.

According to academic Robert Marks, environmental degradation in China had become an ecological crisis by the end of the eighteenth century.

Decades of warfare had also damaged the environment in the period prior to the founding of the PRC.

Water resources

The water resources of China are affected by both severe water quantity shortages and severe water quality pollution. An increasing population and rapid economic growth as well as lax environmental oversight have increased water demand and pollution. China has responded by measures such as rapidly building out the water infrastructure and increased regulation as well as exploring a number of further technological solutions. Water usage by its coal-fired power stations is drying-up Northern China.

According to Chinese government in 2014 59.6% of groundwater sites are poor or extremely poor quality.

A 2016 research study indicated that China's water contains dangerous amounts of the cancer-causing agent nitrosodimethylamine (NDMA). In China, NDMA is thought to be a byproduct of local water treatment processes (which involve heavy chlorination).

Afforestation and deforestation

Between 1700 and 1949, more forests were destroyed in China than in the previous 5,000 years.

Beginning in 1900, China's governments mobilized labor and resources to plant trees. The PRC was the first to make significant progress in afforestation. Prior to the founding of the PRC, the country's forest cover had been reduced to 5-8% and its per capita forest resources ranked 120th out of 160 countries.

As of 2005, China's forest cover was about 20%.

Two large reforestation programs, the Natural Forest Protection Program and the Returning Farmland to Forest program, were announced in late 1998. The programs were piloted in Sichuan, Shaanxi, and Gansu in 1999. They became widely implemented in 2000. The Natural Forest Protection Program called for major reductions in timber harvest, forest conservation, and instituted logging bans in most of Sichuan, Yunnan, Guizhou, and Tibet. The program provided for alternative employment opportunities for former logging industry workers, including hiring them for reforestation work. The Returning Farmland to Forest program paid farmers to plant trees on less productive farmland and provided them with a yearly subsidy for lost income.

In 2001, the United Nations Environment Programme (UNEP) listed China among the top 15 countries with the most "closed forest," i.e., virgin, old growth forest or naturally regrown woods. 12% of China's land area, or more than 111 million hectares, is closed forest. However, the UNEP also estimates that 36% of China's closed forests are facing pressure from high population densities, making preservation efforts especially important. In 2011, Conservation International listed the forests of south-west Sichuan as one of the world's ten most threatened forest regions.

China had a 2018 Forest Landscape Integrity Index mean score of 7.14/10, ranking it 53rd globally out of 172 countries. By 2023, the Chinese government was encouraging deforestation in an attempt to gain food independence.

Tree cover extent and loss

Global Forest Watch publishes annual estimates of tree cover loss and 2000 tree cover extent derived from time-series analysis of Landsat satellite imagery in the Global Forest Change dataset. In this framework, tree cover refers to vegetation taller than 5 m (including natural forests and tree plantations), and tree cover loss is defined as the complete removal of tree cover canopy for a given year, regardless of cause.

For China, country statistics report cumulative tree cover loss of 12,766,739 ha (127,667.39 km2) from 2001 to 2024 (about 7.8% of its 2000 tree cover area). For tree cover density greater than 30%, country statistics report a 2000 tree cover extent of 162,873,593 ha (1,628,735.93 km2). The charts and table below display this data. In simple terms, the annual loss number is the area where tree cover disappeared in that year, and the extent number shows what remains of the 2000 tree cover baseline after subtracting cumulative loss. Forest regrowth is not included in the dataset.

Three Gorges dam

The Three Gorges Dam produces 3% of the electricity in China but has displaced houses and caused environmental problems within the local environment. Due to the construction of the dam over one million people have been displaced from their homes. The dam has also caused frequent major landslides due to the erosion in the reservoir. These major landslides included two incidents in May 2009 when somewhere between 20,000 and 50,000 cubic metres (26,000 and 65,000 cu yd) of material plunged into the flooded Wuxia Gorge of the Wu River.

Coastal reclamation

China's marine environment, including the Yellow Sea and South China Sea, are considered among the most degraded marine areas on earth. Loss of natural coastal habitats due to land reclamation has resulted in the destruction of more than 65% of tidal wetlands around China's Yellow Sea coastline in approximately 50 years. Rapid coastal development for agriculture, aquaculture and industrial development are considered the primary drivers of coastal destruction in the region.

In the South China Sea, coral reefs have been severely destroyed by land reclamation by several countries, with China being one of the top contributors. Of the 7,165 acres of destroyed reefs, China is responsible for 65% of the destruction, having destroyed about 4,648 acres since 2013. The "Great Wall of Sand" was one of the main contributors to the destruction of the reefs. As surrounding countries continue to battle for control over the South China Sea, land reclamation poses as a threat to surrounding environments.

Desertification

Desertification remains a serious problem, consuming an area greater than the area used as farmland. Although desertification has been curbed in some areas, it is still expanding at a rate of more than 67 km2 every year. 90% of China's desertification occurs in the west of the country. Approximately 30% of China's surface area is desert. China's rapid industrialization could cause this area to drastically increase. The Gobi Desert in the north currently expands by about 950 square miles (2,500 km2) per year. The vast plains in northern China used to be regularly flooded by the Yellow River. However, overgrazing and the expansion of agricultural land could cause this area to increase. In 2009, it was estimated that over 200 high-altitude lakes in Zoigê Marsh, which provides 30% of the Yellow River's water, had dried up. In Inner Mongolia, to mitigate the financial impact on families from desertification, women are taught traditional embroidery techniques which they then use to create additional income. The scheme was started by local embroiderer Bai Jingying.

Climate change

Climate change had already impacted China. It increased mortality from extreme weather events, infectious disease, poor air and water quality. The effects of air pollutions are exacerbated by the rise in temperatures. In the future climate change may lead to "typhoons, floods, blizzards, windstorms, drought, and landslides" and to more severe damage from infectious diseases In the years 1970-2016 the occurrence of crop pest and diseases increased 4 times. 22% of that rise are due to climate change. By the year 2100 the occurrence will rise 243% under a low emission scenario and by 460% under a high emissions scenario. China is the biggest producer of wheat and rice in the world. It is in the second place in maize production.

According to one report, China is the country with the largest number of people who can be impacted by sea level rise.

One of the main problems is the melting of glaciers and permafrost in Tibet. These glaciers and permafrost supply water to approximately 2 billion people. The temperatures in the region rise 4 times faster than anywhere in Asia. According to Xinhua News Agency 18% of glaciers already melted from the middle of the 20th century. The water level in big rivers is lowering. This has an impact on the water supply of China because many rivers, including the Yangtze and Yellow River are getting water from the Tibet glaciers. According to China's Ministry of Water Resources 28,000 of rivers disappeared in China by the year 2013 and the melting of Tibet glaciers and permafrost can be one of the causes. The melting also has an impact on the water supply of others countries in eastern Asia, including India, Pakistan, Bangladesh and more, that can lead to conflicts over water. According to Chinese Academy of Science "more than 80 percent of Tibetan Plateau permafrost could be gone by the year 2100, and that almost 40 percent of it would be gone within the "near future." Some researchers predict that most of the Himalayan glaciers will disappear in 20 years.

Pollution

Various forms of pollution have increased as China has further industrialized, which has caused widespread environmental and health problems. China has responded with increasing environmental regulations and a build-up of pollutant treatment infrastructure which have caused improvements on some variables. As of 2013 Beijing, which lies in a topographic bowl, has significant industry, and heats with coal, is subject to air inversions resulting in extremely high levels of pollution in winter months. In response to an increasingly problematic air pollution problem, the Chinese government announced a five-year, US$277 billion plan to address the issue. Northern China will receive particular attention, as the government aims to reduce air emissions by 25 percent by 2017, compared with 2012 levels, in those areas where pollution is especially serious. According to a report published by Greenpeace and Peking University's School of Public Health in December 2012, the coal industry is responsible for the highest levels of air pollution (19 percent), followed by vehicle emissions (6 percent). Ambient air pollution is measured by the amount of particulate matter in the air. This is a result of burning fossil fuels. "Because coal is the primary fuel used to power China's industrial sector, it is responsible for about 40 percent of the deadly fine particulate matter found in China's atmosphere." In January 2013, fine airborne particulates that pose the largest health risks, rose as high as 993 micrograms per cubic meter in Beijing, compared with World Health Organization guidelines of no more than 25. The World Bank estimates that 16 of the world's most-polluted cities are located in China.

Coastal pollution is widespread, leading to declines in habitat quality and increasing harmful algal blooms. The largest algal bloom recorded in history occurred in China around the southern Yellow Sea in 2008, and was easily observed from space.

Rising affluence is another indirect cause of pollution. In particular, car ownership has skyrocketed. In 2014, China added a record 17 million new cars to the road and car ownership reached 154 million.

China is the biggest producer of single use plastic which causes severe pollution. The biggest landfill of the country was filled 25 years before it was planned.

Land pollution

In July 2015, Council on Foreign Relations Director of Asia Studies Elizabeth Economy writing in The Diplomat listed soil contamination as a "poor stepchild" of the Chinese environmental movement, and questioned whether or not recent measures from the Ministry of Environmental Protection would be adequate in combating the problem. In her 2004 book The River Runs Black, she wrote, "China's spectacular economic growth over the past two decades has dramatically depleted the country's natural resources and produced skyrocketing rates of pollution. Environmental degradation has also contributed to significant public health problems, mass migration, economic loss, and social unrest."

Population

China currently has the 2nd largest population in the world but population growth is very slow in part due to the one-child policy. The environmental issues are also negatively affecting the people living in China. Because of the emissions created from the factories, the number of people diagnosed with cancer in China has increased. Lung cancer is the most common form of cancer that is plaguing the population. In 2015, there were more than 4.3 million new cancer cases in the country and more than 2.8 million people died from the disease.

Animal welfare

The People's Republic of China has limited animal protections by international standards, and animal-rights activists have condemned the treatment of animals in the country. Protests and movement towards animal welfare and animal rights have expanded in China, but face resistance from the Chinese government.

Natural disasters

According to Jared Diamond, the six main categories of environmental problems of China are: air pollution, water problems, soil problems, habitat destruction, biodiversity loss and mega projects. He also explained that "China is noted for the frequency, number, extent, and damage of its natural disasters". Some natural disasters in China are "closely related to human environmental impacts", especially: dust storms, landslides, droughts and floods.

Environmental Injustice

China's rural population faces environmental challenges disproportionately as less developed, rural provinces often deal with larger polluting entities and looser environmental regulations. The environmental regulations in rural areas are less strict than the densely populated, urban areas allowing enterprises in industries that contribute greatly to pollution like energy producers move away from cities and continue polluting at levels that would be not be allowed had they remained there. These groups also lobby policy makers in the area to ensure regulations do not change and become stricter.

China's urban population has also been found to face greater environmental issues if they live in lower-priced housing. In a 2023 experiment the urban tree canopy (UTC) cover of Chinese cities was found to relate to nearby housing prices where the lower value the housing, the lower amount of UTC cover available. UTC cover is an important marker for sustainable development, providing many ecological benefits as well as improving the quality of life of residents. The distributions of these benefits is unequal, the areas with the highest housing prices have the most UTC cover, meaning residents are likely to have better mental health and live in an area with a greater degree of sustainable development. Those living in the lower priced housing receive much less benefit and likely live in areas with greater environmental issues.
