What are the benefits of reefs?
Ocean reefs act as a buffer, protecting shorelines and coastal communities from the impact of big waves, storms and hurricanes as they make landfall. These natural barriers help prevent loss of life, protect property – such as homes, ports and marinas – and guard against shoreline erosion.
How do corals help the ecosystem?
This process regulates carbon levels in the waters around reef systems, providing an environment for microorganisms to thrive. Finally, corals recycle matter and nutrients from broken-down elements, generating new life from old in a process that self-perpetuates the reef’s ecosystem.
Why is the Great Barrier Reef declining?
Australia’s Great Barrier Reef has declined by 50% since 1985, due to storm damage, coral bleaching and waves of crown-of-thorns starfish suffocating the coral. Warming ocean waters prevent corals laying down their calcium carbonate skeleton, which inhibits the growth essential for a healthy reef ecosystem.
Why are corals bleached white?
Colourful coral formations are highly sensitive to changes in water temperature, light conditions or nutrients, and can eject the algae that live and feed on them – a phenomenon known as bleaching.
How much has the Great Barrier Reef declined since 1985?
Australia’s Great Barrier Reef has declined by 50% since 1985. Image: REUTERS/David Gray/File photo. Beneath the ocean’s surface, colourful islands covered in algae are working hard to help the marine environment. Although they look more like plants or rocks, corals are animals that are essential for the planet.
What happens when coral turns white?
Stressed coral turns white, leaving it vulnerable to disease, and if the algae loss occurs over a lengthy period, the reef could eventually die. When the algae disappear, creatures further up the food chain disappear, too.
What happens when coral dies?

And despite only covering 0.1% of the earth’s surface, they contain the highest number of species of any ecosystem besides rainforests.
How does connectivity help coral reefs?
But this connectivity could also save coral reefs: if one coral reef is kept healthy and over time adapts to climate change or other stressor, it could spread those better-adapted traits to other coral reefs through the movement of coral larvae. The key is keeping coral reefs healthy in the areas where corals are adapting and in the areas where the adapted corals are settling.
Why do we need to reduce threats to coral reefs?
To ensure people and wildlife can continue relying on the lifesaving services coral reefs provide , we need to reduce threats to reefs.
Why do coral reefs have to be genetically connected?
Because ocean currents tend to follow the same course , one coral reef can be genetically connected to another coral reef hundreds of miles away—one coral reef will provide the baby corals, and the other coral reef will provide the home upon which the larvae settle. When one coral reef becomes too overcome by local stressors, it could affect other coral reefs that are far away.
