This answer would be true, b/c it is not false. It's not false b/c coral reef ecosystems <em><u>DO</u></em> support over a million different species.
if the earth had not evolved it would be just like every other planet, no life forms, not polluted and pure. it would be clean and there would probably be a few organisms but not how we are now. Global warming would not be there and the plastic in the oceans would also not be there.
