Coral reefs have managed to bounce back, despite being under constant threat of extinction. However, marine scientists caution these fragile ecosystems are still being threatened by global warming, pollution and human activity.
The discovery of a large number of coral reefs in excellent health has been quite a joyous occasion for the researchers who routinely deal with ominous news like mass die-offs, worldwide bleaching events, oil spills, and such other calamities which have been pushing the coral reefs towards extinction, reported The Washington Post.
A decade-long study of remote islands in the Central Pacific has indicated that these coral reefs might survive despite threats posed by global warming brought on by climate change and warming of the oceans due to increasing amounts of carbon dioxide introduced by burning of fossil fuels.
In a large scale study covering 56 islands, researchers studied 450 locations that were once teeming with coral reefs. Researchers looked at regions spanning from Hawaii to American Samoa. They even investigated locations in the remote Line and Phoenix Islands as well as the Mariana Archipelago. To their surprise, they realized there are quite a few locations where coral reefs have defied the odds and bounced back to life. Smith's report was published recently in the journal Proceedings of the Royal Society B.
