7 Adorable Photos of Sea Otters Saving the World

Just by munching on one of their favorite foods, sea otters may be combating climate change. New research out of the University of California Santa Cruz (UCSC) suggests that a thriving population of sea otters helps to keep sea urchin populations in check. Sea urchins devour sea kelp, which absorbs vast amounts of carbon dioxide. The theory is outlined in the journal Frontiers in Ecology and the Environment by lead authors Chris Wilmers and James Estes, who are both UCSC professors. The researchers combined 40 years of data on otters and kelp bloom from Vancouver Island to the western edge of Alaska's Aleutian Islands, and they found that otters "undoubtedly have a strong influence" on the cycle of CO2 storage.
