    Coral reefs have been called the “rainforests of the oceans” because they house the largest diversity of marine life, supporting about a quarter of all marine organisms. They also provide food for an estimated 500 million people around the world.

    It is estimated that all of the tropical coral reefs in the world will be destroyed by the end of the century due to the rising acidity of the oceans caused by an accumulation of man-made carbon dioxide in the atmosphere.  Studies have found that all coral reefs will stop growing and start to disintegrate when atmosphere CO2 reaches 560 parts per million and the projected time frame for this is by the end of the 21st-century.
