Specifically, the plastic items that wind up in the area of Thai reefs is literally the death of coral. "Plastic waste associated with disease on coral reefs" published in Science magazine contains shocking data. In fact, comparing coastal populations and the size of reefs, Thailand is the worst dumper of plastic waste on Earth. They will throw, accidentally and on purpose, more than 8.9 million plastic items into the Gulf of Thailand and Andaman Sea. The now undebatable slow death of Thai coral by plastic is by premeditated acts, planned or careless.
