A new study from the University of California at Santa Cruz reports that sea otters can help to stop global warming by keeping CO2 emissions in check.  Growing carbon dioxide emissions are a major cause of global warming.  Sea otters feed on sea urchins, which typically eat kelp.  However, kelp absorbs huge amounts of carbon dioxide.  Thus, if sea otters feed on sea urchins, they help insure that the kelp populations remain high and positively impact the carbon cycle.  Read more here.
