Destroyed coral reef as result of dynamite fishing, the Philippines. Roughly one-quarter of coral reefs worldwide are already considered damaged beyond repair, with another two-thirds under serious threat. Major threats to coral reefs and their habitats include: Corals cannot survive if the water temperature is too high.

Global warming has already led to increased levels of coral bleaching, and this is predicted to increase in frequency and severity in the coming decades. Such bleaching events may be the final nail in the coffin for already stressed coral reefs and reef ecosystems.

These include cyanide fishing, blast or dynamite fishing, bottom trawling, and muro-ami banging on the reef with sticks. Bottom-trawling is one of the greatest threats to cold-water coral reefs. This affects the ecological balance of coral reef communities, warping the food chain and causing effects far beyond the directly overfished population.

Careless boating, diving, snorkeling, and fishing happens around the world, with people touching reefs, stirring up sediment, collecting coral, and dropping anchors on reefs. Some tourist resorts and infrastructure have been built directly on top of reefs, and some resorts empty their sewage or other wastes directly into water surrounding coral reefs.

Urban and industrial waste, sewage, agrochemicals, and oil pollution are poisoning reefs. These toxins are dumped directly into the ocean or carried by river systems from sources upstream.

Where can I find coral reefs?

Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and sea anemones, corals secrete hard carbonate.

When the health of the coral is threatened, the existence of every other species is threatened, too. The destruction of coral is leading to the endangerment and extinction of thousands of other species. 2. The Destruction of Coral Reefs.

Coral reefs are being destroyed by anthropogenic fluxes in their environment. This site was created to show the importance of the coral reefs around the world, and a possible solution to stop the destruction of them. Feb 14,  · The Phi Phi islands have been popular with tourists since they were featured in Danny Boyle’s film "The Beach," but authorities say visitors are contributing to the damage of the coral reefs.

Sewage pollution is shockingly widespread: A full 96 percent of places that have both people and coral reefs have a sewage pollution problem, according to recent research by Stephanie Wear, The Nature Conservancy’s lead scientist for coral reef conservation.
