Filmed in the USA, Senegal, Vietnam, France, Colombia and Brazil, the documentary explores the relatively newly-discovered potential of oceans to absorb much more carbon from the atmosphere than even tropical rainforests. This "Blue Carbon" as scientists are now calling it, can be found in salt-marshes, sea-grasses and mangroves, and are becoming increasingly attractive investments for big corporations looking to offset their emissions through carbon credit schemes. This documentary urges us to take stock of nature’s true value by listening to and learning from the communities on the front lines of climate change. Presented by Wellfleet Harbor Actors Theater in collaboration with Mass Audubon's Wellfleet Bay Wildlife Sanctuary.
