If global warming continues the coral reefs may be completely lost by 2100. When sea temperatures rise, the algae that give coral its bright colours leave their host, causing it to look white, hence the term 'coral bleaching'.

The correct answer to this open question is the following.

There is no question here, just a statement.

If this is a true or false question, then the correct answer is "true."

It is true that if global warming continues the coral reefs may be completely lost by 2100. When sea temperatures rise, the algae that give coral its bright colors leave their host, causing it to look white, hence the term 'coral bleaching'.

That is so important to put an end to all things that continue to pollute the environment. Warmer temperatures are what produce the bleaching of coral. And if this happens all maritime life suffers the consequences. Global warming is real and leaders of the world need to accelerate the actions in order to prevent a disaster that cannot be overturned in the future.
