Overfishing in certain coral reefs have begun to cause a positive feedback loop that may soon become unstoppable. Areas where the populations of fish that eat algae have been dwindling, the amount of algae has been increasing. This causes harm to coral reefs, as the algae overpowers the coral reefs, either by using up the available oxygen or by spreading disease to the reefs. What causes the runaway feedback loop is that as algae kills off coral reefs, the amount of area habitable for algae increases.
This shows that even the smallest amounts of human impact can have drastic effects on the health of the ocean and on oral reefs. Something as simple as fishing bottom-feeders can cause a positive feedback loop that can change the composition of a coral reef. This once again shows that people must become increasingly aware of the impacts they have on the environment.
