Introduction

Something is happening in oceans around the world - something bad. Something very, very bad. The coral reefs found in the oceans are slowly being killed, and this is causing a lot of problems for the organisms that need coral reefs to live. As a result plants and animals that live in the coral reefs and help keep their ecosystem balanced are also being affected. But what is causing coral reefs to die?

What effects is it having on the rest of the world? Is this something that can be stopped? If so, how do we stop it? Why haven't we stopped it yet?
