This episode of Across The Margin : The Podcast features an interview with Vincent Doumeizel, Senior Adviser on the oceans to the United Nations Global Compact as well as director of the Food Programme at the Lloyd’s Register Foundation. A self-described optimist and global citizen, Vincent has devoted himself to promoting environmental solutions based on sea resources, especially seaweed. Vincent is the author of The Seaweed Revolution which argues that seaweed is a vital, underutilized resource with the potential to solve major global crises, from Climate Change and food security to plastic pollution. His latest book — The Power of Plankton : How Plankton Made Life on Earth Possible and Why It’s The Key to our Future — is the focus of this episode. The Power of Plankton uncovers the hidden connections between these microscopic organisms and the survival of our planet. Plankton, many will be surprised to learn, represents 90% of ocean biomass and is the source of life on our planet. It is responsible for oxygen, our rains, the rocks, our cliffs, our food, as well as our climate. In The Power of Plankton readers will encounter unforgettable stories such as a scientist who survived 65 days crossing the Atlantic eating only plankton, and the truth behind ancient myths of “blood rain” traced back to plankton blooms. The Power of Plankton is a timely exploration of the smallest life forms with the largest impact — and why the future of our planet may depend on them.
