Seaweed and other algae suffocate and kill corals by preventing them from engaging in photosynthesis.

After researching coral reefs near the Fiji Islands, scientists can be sure that seaweed and algae are doing more than just benefiting from the dwindling state of coral bleaching. In fact some seaweeds are using their very own chemicals to severely harm and prevent the recovery of corals. Of course the overfishing of certain algae-eating fish species doesn’t help matters but instead allows the seaweeds to overgrow and conquer the desperate corals. Scientists hope that bans on harvesting seaweed-eating fish will help defeat the chemically murderous seaweed.
