“Sea otters might be on the frontlines of the fight against global warming, according to a new study showing the fur-coated swimmers keeping sea urchin populations in check, which in turn allows carbon dioxide-sucking kelp forests to prosper,” Discovery reports.
“Researchers from the University of California, Santa Cruz, looked at 40 years of data on otters and kelp blooms from Vancouver Island to the western edge of Alaska's Aleutian Islands. They said they found that sea otters have a positive indirect effect on kelp biomass by preying on sea urchins.”
