Professor Tim Flannery investigates how seaweed is helping to save the world – from growing the foods of the future, helping clean polluted water and even combating climate change.

Growing seaweed is now a $10 billion a year global industry. Tim travels to Korea to see some of the biggest seaweed farms in the world and meets the scientists who are hoping to create a seaweed revolution here in Australia.
