Coral looks like rock, but it is actually a huge collection of tiny clear animals called coral polyps. The bright colour of coral comes from tiny sea plants called algae.

Coral and algae depend on each other to live. Coral may feel tough but it is very sensitive. today, many coral reefs are dying and there are many reasons why.

First of all, the ocean are getting warmer. This kills the algae and so the coral reefs lose their color and food

Water pollution , fishing with dynamite as well as the careless collection of coral also hurt coral reef. If we do not take action, all the reefs will die in around 20 years

This will lead thousands of sea creatures to extinction. We can help save the world is coral reefs by joining an evironmental organization like Reef Relief/ it is worth a try!
