Key Threats



The Yellow Sea Ecoregion is also one of the world’s most heavily disturbed/exploited marine ecoregions. Major threats include:

  • Loss of habitats: Loss of coastal wetlands in the past century is more than 40%.
  • Overfishing: Decrease of most traditional target species (demersal fish) of high commercial value by more than 40% in weight of catches despite the continuous increase of fishing efforts. Replacement of larger, commercially important species by smaller or less valuable ones with high turnover rates.
  • Pollution: A vast population of 600 million (10% of the world’s total) living in the watersheds draining into the Yellow Sea Ecoregion. Inadequate wastewater treatment in all the continental countries surrounding this Ecoregion
