What's the ocean like in China?

China has nearly 3.3 million square kilometers of sea area, including the East China Sea, the Yellow Sea and the South China Sea. Among them, the East China Sea and the Yellow Sea belong to temperate zones, while the South China Sea belongs to tropical oceans.

The climate of China sea area is complex, and the biological species in the north and south sea areas are quite different. The species in the northern waters are temperate, while the species in the South China Sea are mostly tropical. The salinity and temperature of nutrients in different water masses in Minjiang River and China Sea are different, and the marine ecological environment is complex.

China is rich in fishery resources, and the South China Sea is known as the "world fish tank". However, in recent years, due to overfishing, fishery resources have been seriously damaged, and the number of some fish species has been greatly reduced or endangered.

The environmental pollution in China sea area is serious, and the pressure in coastal waters is enormous. A large number of industrial, agricultural and domestic pollutants are discharged, which leads to serious problems such as eutrophication, heavy metal pollution and marine garbage.

China sea area is rich in marine resources, oil, natural gas and mineral resources. However, the over-exploitation of resources has also caused certain environmental problems.

The coastal marine economy in China is developing rapidly, and the rise of marine industry drives economic growth. However, it also faces the problems of lack of marine resources and increased environmental pollution.
