The Great Coral Reef almost circles New Zealand it has more marine life than anywhere else in the world

That's a runon sentence. How do you think you should correct it?

The Great Coral Reef almost circles New Zealand and it has more marine life than anywhere else in the world.

That's fine, Martin, except that you need a comma before "and." Your sentence has two independent clauses that need to be separated by a comma.

Actually, the statement you made about the Great Coral Reef is incorrect. The Great Barrier Reef, which is located off the coast of Queensland, Australia, is the world's largest coral reef system, not the Great Coral Reef. It stretches over 2,300 kilometers and is home to a vast variety of marine life.

It's important to fact-check information to ensure accuracy and avoid spreading incorrect details.
