Our emission of greenhouse gases, namely significant amounts of Co2 over several hundred years, is altering our climate. We often turn to trees and replanting vegetation, Green Carbon, as the opportunity to recapture carbon from our atmosphere, but coastal ecosystems are exceptionally apt at carbon capture and storage, too - almost more effective than the Green Carbon counterpart.

In this episode we speak with Lucy McMahon, Marine and Coastal Scientist and ocean optimist, about Blue Carbon; what it means, how effective our Blue ecosystems are at moderating our planetary climate, and why we need to protect them.
