Overfishing: The Great Barrier Reef

The bleaching happens due to the climate change caused by humans when changing the climate. When corals become stressed by those factors, algae that live in its tissues leave and, consequently, the coral is left behind bleached and more susceptible to diseases. The coral does not die when bleached, it can still survive the bleaching event but it will be more vulnerable. The Great Barrier Reef has a very large diversity, including some endangered and endemic species. Climate change is not the only issue, pollution and fishing are other threats to the reef. Pollution also brings crown-of-thorns starfish, which preys on coral polyps. The overfishing may disrupt the food chain and cause even more destruction.
