From new sources of energy and nutritious food to limitless biodiversity and potential settlement sites the ocean is the last great unexploited frontier on earth. This blog is a window into that future, and seeks to advance discussion on how new technologies, consumer practices and business models can create an ecologically and economically sustainable future on and in the seas. Over the next decade, a convergence of economic, climatological and technological forces will bring the oceans back to the forefront as a new frontier for human activity.
