Yellow Sea
State of the environment

The Yellow Sea is 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 60% of tidal wetlands around the 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. This degree of loss of area, widespread pollution, algal blooms and declines of invertebrate and vertebrate fauna have resulted in the classification of this ecosystem as endangered.

In addition to land reclamation, the Yellow Sea ecosystem is facing several other serious environmental problems. Pollution is widespread and deterioration of pelagic and benthic habitat quality has occurred, and harmful algal blooms frequently occur. Invasion of introduced species are having a detrimental effect on the Yellow Sea environment. There are 25 intentionally introduced species and 9 unintentionally introduced species in the Yellow Sea Large Marine Ecosystem. Declines of biodiversity, fisheries and ecosystem services in the Yellow Sea are widespread.

The tidal flats of the Yellow Sea are considered endangered.
