Coral reefs form through the accumulation of calcium carbonate secreted by coral polyps over time. These structures provide a habitat for a diverse range of marine species.
Some of the threats coral reefs face include:
-
Climate change: Rising sea temperatures can lead to coral bleaching, where corals expel the algae living in their tissues, causing them to turn white and potentially die.
-
Ocean acidification: Increased carbon dioxide levels in the atmosphere can lead to ocean acidification, which makes it harder for corals to build their calcium carbonate skeletons.
-
Overfishing: Removing key species from the coral reef ecosystem can disrupt the delicate balance and lead to ecosystem collapse.
-
Pollution: Runoff from land-based sources can introduce chemicals and nutrients into the water, which can harm coral reefs.
-
Coastal development: Construction, dredging, and other coastal activities can damage or destroy coral reefs and their habitats.
