Australia's Great Barrier Reef Being Choked by Seaweeds

According to an interview held by the Agence France-Presse, Australia's Great Barrier Reef is overgrown in places by seaweed and that could be a worrying indication of the coral structure's health.  A lack of algae-eating fish is a big reason for this trend. Surveys have already shown that the reef is at risk from global warming and more than 40 percent of the areas closest to the shore are overgrown with seaweed. The Center of Excellence for Coral Reef Studies' Professor David Bellwood said the offshore reefs, those about 12.4 miles from the continent's eastern coast were largely untouched by the algae. He said the best defense for the reef would be clean water and the existence of herbivorous fish which could graze on the weeds.
