Coral reefs are dying.
Between 70% and 90% of all reef systems could disappear within the next two decades because of pollution and climate change, according to new research.
That projection, which researchers from the University of Hawaii Manoa presented at annual Ocean Sciences Meeting last week, suggests that by the end of the century, there could be few to no suitable sites for coral reefs anywhere in the world.
