A new study by researchers at uc santa cruz has revealed how sea otters can help reduce climate change. Sea otters feed on sea urchins, and when the population of otters is healthy, the otters can reduce the impact of urchins on kelp. According to the paper released in the publication frontiers in ecology and the environment, when kelp forests are allowed to prosper, the kelp can absorb 12-times the amount of carbon dioxide (than if they were stunted by urchins).
