Presentation on the
theme: coral reefs
did: Salenko Egor and Heitkulov Gleb

2.

O 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.

3.

O 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.

4.

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

5.

O 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

6.

O 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!
