Facts about Coral Reefs

Coral reefs cover about 0.1 % of the ocean’s but they nurture 25 % of the world’s marine species.

  • Coral reefs are home to over 25% of the world's marine species.
  • The economical impact of coral reefs is 36 billion dollar.
  • Reefs are a source of food and income for over 500 million people.
  • 93% of heat trapped in the earth’s atmosphere is absorbed by the ocean.
  • 29% of the corals of the Great Barrier Reef have died last year.

Coral Reefs are dying

Coral reefs are dying because of climate change.Major coral bleaching events are observed during 1998, 2016, 2017 and 2020.

Coral bleaching

Coral bleaching is vulnerable to coral reefs.

Healty Coral

Coral and algae depend on each other to survive.

Corals have a symbiotic relationship with microscopic algae called zooxanthellae that live in their tissues. These algae are the coral’s primary food source and give them their color.

Stressed Coral

If the coral stressed then algae leaves the coral.

When the symbiotic relationship becomes stressed due to increased ocean temperature or pollution, the algae leave the coral’s tissue.

Bleached Coral

After that the Coral is left bleached and vulnerable.

Without the algae, the coral loses its major source of food, turns white or very pale, and is more susceptible to disease.

Prediction

4,600 square miles of coral reefs worldwide are predicted to be killed in 1 year!

What kills Coral Reefs :-

  • Change in ocean temperature - increased ocean temperature caused by climate change is the leading cause of coral bleaching.
  • Runoff and pollution - Storm generated precipitation can rapidly dilute ocean water and runoff can carry pollutants, which is harmful to near-shore corals.
  • Overexposure to sunlight - When temperatures are high, high solar irradiance contributes to bleaching in shallow-water corals.
  • Extreme low tides - Exposure to the air during extreme low tides can cause bleaching in shallow corals.

Threat

More than 50% of corals are under threat in recent years

Coral Planting Experiment

Currently only 2 successful types of coral planting experiment

Pain Points :-

  • Out of 7 types of experiments, only 2 are successful.
  • Mainly due to insufficient funds to conduct thorough R&D, to procure advanced tools and diving overheads for daily operations.
