Report: Caribbean coral reefs could soon vanish

Many of the Caribbean's coral reefs could vanish in the next 20 years, according to a report published by the International Union for the Conservation of Nature (IUCN). Data from more than 35,000 surveys suggests that habitats have declined by more than 50% since the 1970s. The report's authors believe that over-fishing and disease is mainly to blame.
