Over 90% of the Great Barrier Reef, one of the most pristine and productive ecosystems on earth, is suffering from coral bleaching. Bleaching occurs when the coral looses its color from expelling the algae living in a symbiotic relationship with the coral, which allows the coral survive. Without it, the coral faces a death sentence along with millions of other organisms in reef ecosystems. The effects of climate change unthwarted on oceans such as acidification, deoxygenation and rising temperatures have the extinction of such reefs pinned for 2050. WE CAN AND MUST STOP THIS!!
