This article discusses coral reefs – Back from the brink: the global effort to save coral from climate change. Underwater nurseries offer glimmer of hope for endangered ecosystems, encouraging growth of coral fragments on fiberglass structures anchored to the seabed.
As an ocean early warning system, coral reefs have been sounding the alarm for years. They have been bleached white by marine heatwaves and killed off en masse by a combination of factors including pollution, overfishing, acidification and climate change.
But now scientists in Florida, and other tropical locations worldwide, are attempting to stop the rot by creating coral “nurseries” in which young populations can be raised in controlled conditions before being planted on denuded reefs.
