The last several decades have taken a toll on the oceans: Some fish populations are collapsing, plastic is an increasing problem and climate change is leading to coral bleaching — as well as a host of other problems. But marine biologist and World Economic Forum programme lead Alfredo Giron says there's room to hope for the seas. He works to create systems that governments and the fishing industry can use to make sure fishing is legal and sustainable so oceans thrive for years to come. In this encore episode, he talks to host Aaron Scott about his work and how managing the ocean is a lot about managing people.
