"Freezer plan"
A meeting in Denmark took evidence from researchers that most coral reefs will not survive even if tough regulations on greenhouse gases are put in place. Scientists proposed storing samples of coral species in liquid nitrogen. Freezing samples for the future may be a necessary option.

''Well it's the last ditch effort to save biodiversity from the reefs which are extremely diverse systems," said Simon Harding from the Zoological Society of London. It is something that needs to be looked at in detail, but we can definitely store the species and save them in that way. Scientists have open their eyes, or they are finally accepting that human kind will not leave a lone corals, meaning they will disappear in just a couple of years. Corals have decreased in such big amounts, we only have coral now on less than a quarter of 1% of the ocean! Reefs are a key source of food, income and coastal protection for around 500 million people worldwide.
