III. Threats to Coral Reefs

Coral reefs, one of the most diverse ecosystems on Earth, are facing numerous threats that put their survival at risk. Understanding these threats is crucial for effective coral reef conservation efforts.

Pollution and Runoff

Pollution from various sources poses a significant threat to coral reefs. Runoff from agricultural activities, urban development, and industrial sites can introduce excessive amounts of nutrients and chemicals into the waters surrounding coral reefs. This pollution can lead to harmful algal blooms, reduced water quality, and increased vulnerability to diseases for corals.

Coral Bleaching

Coral bleaching occurs when corals expel the symbiotic algae living within their tissues due to environmental stressors such as high water temperatures or pollution. Without these algae, which provide essential nutrients and give corals their vibrant colors, the corals become pale or white. If prolonged or severe bleaching events occur, it can lead to mass coral mortality.

Overfishing and Destructive Fishing Practices

The overexploitation of fish populations associated with coral reefs has detrimental effects on reef ecosystems. Overfishing disrupts the delicate balance between predators and prey on the reef, causing cascading effects throughout the food web. Additionally, destructive fishing practices such as blast fishing or using cyanide to capture fish can directly damage coral habitats.
