    Ships are not meant to go near coral reefs anymore.
  • Logging
    When people cut down trees that are close to a river the soil will go into the river and end up in the ocean!
    People are not allowed to cut down trees near rivers.

    When the water gets too hot or too deep the algae that live in the coral go away and the coral loses its colour and dies!
