Answer: Less than 0.1%
Notes: As per reports, coral reefs occupy less than 0.1% of the total ocean floor area but support around 25% of all known marine species at some stage, hence critical for marine biodiversity. This highlights their huge ecological significance disproportionate to size. Climate change poses significant risk to their survival. Coral Vita is a Dubai startup attempting to restore coral reefs by growing heat-resistant corals in a land-based lab to be eventually transplanted back to sea. Its coral farm in Dubai houses corals trimmed from Gulf waters, providing ideal conditions for them to regenerate before replanting.
