A high volume of human waste has been dumped into the South China Sea over the past five years by at least 270 Chinese vessels and has caused damage to the areas’ reefs and fish populations, says Liz Derr, who heads US artificial intelligence company, Similarity Incorporated. 

By using satellite imagery analysis, Derr claims that the company’s study of the South China Sea region has identified at least 236 Chinese ships which have amassed in the disputed-region, causing algae blooms and large decline in migratory tuna in the area. 

Derr further claims the damage to the reef caused by the Chinese waste dumping has the potential to cause a hunger crisis for millions living in the South China Sea region who are dependent on the tuna as a source of food and income.
