With the rising rate of carbon dioxide released into the atmosphere, and rising concerns about climate change, some effort is being made to own up to the fact that since we are the ones that put the excess CO2 there, we need to be the ones to remove it. Well, another species — sea otters — has been found doing their part to help and a new study has shown that they are helping more than we previously thought.
The links between sea urchins, sea otters, kelp forests and carbon dioxide has been known for some time now. Sea urchins feed ravenously on kelp forests when their populations go unchecked. Sea otters consider sea urchins to be a favourite food, and happily dwindle their populations, which allows the kelp forests to thrive. Thriving kelp forests are very good at removing carbon dioxide from the atmosphere.
After studying 40 years worth of data involving kelp forest densities, both with and without otters, University of California Santa Cruz professors Chris Wilmers and James EstesRead More »from Sea otters, urchins, kelp help combat climate change
