What is coral bleaching, and why is it a threat to the reef?
Coral bleaching is a significant and alarming phenomenon affecting coral reefs worldwide, including the Great Barrier Reef. It occurs when coral polyps, the tiny organisms that make up coral colonies, expel the symbiotic algae called zooxanthellae, which provide them with essential nutrients and vibrant colors. This expulsion of algae causes the corals to lose their color and turn white or pale.
When the water becomes too warm, the coral polyps expel the zooxanthellae as a survival response, as the algae become toxic to the coral at higher temperatures. This loss of the symbiotic relationship between coral and algae weakens the corals, making them more susceptible to diseases and less capable of recovering from stressors.
Coral bleaching is a severe threat to coral reefs for several reasons:
Ecosystem Disruption: Coral reefs are incredibly diverse ecosystems that provide habitat and sustenance for countless marine species. When coral bleaching occurs, it disrupts this delicate balance, impacting the entire ecosystem.
Economic Impact: Many coastal communities depend on coral reefs for their livelihoods, primarily through fishing and tourism. Bleaching events can lead to reduced fish populations and damage to the tourism industry, affecting local economies.
Loss of Biodiversity: Prolonged or severe bleaching can lead to coral death. This, in turn, reduces the biodiversity of the reef, as corals provide a foundation for numerous other species.
Reef Health: Repeated bleaching events weaken the resilience of coral reefs, making them more susceptible to additional stressors such as disease and pollution.
