Scientists Are Breeding Sea Stars in a Lab to Rehabilitate Warming Oceans
Climate change helped to kill most of the world’s sunflower sea stars. Resurrecting them could revive carbon dioxide-sequestering kelp forests.

Researchers at University of Washington’s Friday Harbor Laboratories are working to repopulate the ocean with captive-bred sunflower sea stars after a disease magnified by a warming ocean killed nearly 91% of the global population that stretched from Mexico to Alaska.
