Scientists race against time to prevent wipeout of world's coral reefs
There were startling colours in Maldives just a year ago, a dazzling array of life beneath the waves. Now this Maldivian reef is dead, killed by the stress of rising ocean temperatures
Maldives: There were startling colours in Maldives just a year ago, a dazzling array of life beneath the waves. Now this Maldivian reef is dead, killed by the stress of rising ocean temperatures. What's left is a haunting expanse of gray, a scene repeated in reefs across the globe in what has fast become a full-blown ecological catastrophe.
The world has lost roughly half its coral reefs in the last 30 years. Scientists are now scrambling to ensure that at least a fraction of these unique ecosystems survives beyond the next three decades.
The health of the planet depends on it: Coral reefs support a quarter of all marine species, as well as half a billion people arou-nd the world.
"This isn't something that's going to happen 100 years from now. We're losing them right now," said marine biologist Julia Baum of Canada's University of Victoria. "We're losing them more quic-kly than I think any of us ever could have imagined."
Even if the world could halt global warming now, scientists still expect that more than 90 per cent of corals will die by 2050. Without drastic intervention, we risk losing them all.
