The

environment of China (Chinese: 中国的环境) comprises diverse biotas, climates, and geologies. Rapid industrialization, population growth, and lax environmental oversight have caused many environmental issues and large-scale pollution.[1]

Geology

People's Republic of China) consists of three Precambrian cratons surrounded by a number of orogenic belts. The modern tectonic environment is dominated by the continued collision of India with the rest of Asia starting 40–50 million years ago. This has formed the Himalayas and continues to deform most of China.[2] China has vast mineral reserves,[3] a significant earthquake risk in its western regions and rare isolated active volcanoes throughout the country.[4]

Many geological concepts were discovered very early in China's history. However, it was not until the adoption of European
natural science in the late 19th century that geology became a science in China.[5]

Wildlife

vertebrates including 4,936 fish, 1,269 bird, 562 mammal, 403 reptile and 346 amphibian species.[7] In terms of the number of species, China ranks third in the world in mammals,[8] eighth in birds,[9] seventh in reptiles[10] and seventh in amphibians.[11]

Many species of animals are endemic to China, including the country's most famous wildlife species, the giant panda. In all, about one-sixth of mammal species and two-thirds of amphibian species in China are endemic to the country.[8][11]

Wildlife in China share habitat with and bear acute pressure from the world's largest population of
nature reserves, covering a total area of 149.95 million hectares (578,960 square miles), about 15 percent of China's total land area.[13]

Flora

fungi and 3000 species of bryophytes.[14][15][16] More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora.[17] These landscapes provide different ecosystems and climates for plants to grow in, creating a wide variety of different flora spanning over not just China, but different parts of the world.[18]

Climate

types of China

Owing to tremendous differences in latitude, longitude, and altitude, the

Siberian anticyclone
dominates during winter, bringing cold and comparatively dry conditions. The advance and retreat of the monsoons account in large degree for the timing of the rainy season throughout the country. Although most of the country lies in the temperate belt, its climatic patterns are complex.

, Heilongjiang has a 24-hour average temperature in January approaching −30 °C (−22 °F), while the corresponding figure in July exceeds 18 °C (64 °F). By contrast, most of Hainan has a January mean in excess of 17 °C (63 °F), while the July mean there is generally above 28 °C (82 °F).

Precipitation is almost invariably concentrated in the warmer months, though annual totals range from less than 20 millimetres (0.8 in) in northwestern Qinghai and the Turpan Depression of Xinjiang to easily exceeding 2,000 millimetres (79 in) in Guangdong, Guangxi, and Hainan. Only in some pockets of the Dzungaria
region of Xinjiang is the conspicuous seasonal variation in precipitation that defines Chinese (and, to a large extent, East Asian) climate absent.

Annual sunshine duration ranges from less than 1,100 hours in parts of Sichuan and Chongqing to over 3,400 hours in northwestern Qinghai. Seasonal patterns in sunshine vary considerably by region, but overall, the north and the Tibetan Plateau are sunnier than the south of the country.

Climate change

per-capita basis, China's carbon emissions are considerably less than countries like the United States.[21] It has also been noted that higher-income countries have outsourced emissions-intensive industries to China.[22][23] On the basis of cumulative CO2 emissions measured from 1751 through to 2017, China is responsible for 13% globally and about half of the United States' cumulative emissions.[24][25] China is now the world's largest polluter and in 2023 recorded it's hottest year on record with an average temperature of 10.7 C.[26]

China is suffering from the negative
carbon neutral by 2060 by adopting "more vigorous policies and measures."[27] The GHG emissions of China will probably peak in 2025, and by 2030 they will return to 2022 levels. However, such pathway still leads to 3 degree temperature rise.[28]

Environmental issues

Rapid industrialization, population growth, and lax environmental oversight have caused many environmental issues, such as large-scale pollution in China.[29] 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.[30]

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.[31]

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.[32] Diamond also states that, "China is noted for the frequency, number, extent, and damage of its natural disasters".[32]

Many of the Chinese citizens started to wonder if air pollution is the cause of the increase of lung cancer. This question began to rise because the citizens in China must constantly wear face masks to avoid breathing in the hazardous particles from their polluted skies. Some experts agree that it is the reason, but others say there isn't enough evidence. Wang Ning, deputy director of the Beijing Office for Prevention and Control, says he has seen a rise in a certain cancer called adenicarcinoma, which is a mucus that is seen as a side effect from pollution. China's lung cancer rate is 32% of the entire world's lung cancer patients. Meanwhile, as lung cancer increases, gastric, esophageal, and cervical cancer have all decreased in China.[33]
