Great Barrier Reef Under Threat

Description:The world's largest living structure is in danger. Australia's Great Barrier Reef is under imminent threat from development, according to a U.N. Report. UNESCO - the United Nation's Educational Cultural and Scientific Organisation - is recommending that the site be put on an official danger list next year if urgent action isn't taken.
