The need for food and livelihood has led the people living there to fish and survive off the natural resources the coral reef has to offer them. Since coral reefs are among the most diverse fishing grounds, this has caused overfishing and numerous other drastic events to occur. Coral fish are caught for food, sport and live fish art such as tanks and aquariums. Chemical fishing, which includes the use of cyanide to stun and capture live fish, causes the death of coral polyps and also degrades coral reef habitat. This causes coral bleaching and “re-establishing the symbiosis can take six months to a year or more” (Threats to coral reefs: the effects of chemical pollution – Marine Biodiversity Wiki, no date). Another fishing method that can cause a devastating impact on corals is dynamite fishing. This way of fishing shatters coral colonies and kills the coral tissues of adjacent colonies (The Nature Conservancy, 2016). Over time, other types of algae will replace the dead, poisonous zooxanthellae expelled into the coral. Changes in the algae that live on the coral will lead “to changes in the species of fish and other animals that live on the reef.” (Coral bleaching, n
