The ocean covers 70 percent of our planet and supplies half of the oxygen we breathe. Unfortunately, we haven’t taken great care of it: the climate crisis and our burning of fossil fuels are changing its weather-regulating systems, raising its waters to threatening heights and acidifying its pH balance beyond what its species can survive. And yet, recent climate action has primarily focused on land, leaving the ocean neglected and missing the science, policy and funding it needs in order to continue sustaining its life – and ours. In this episode, originally aired in December 2021, we interview Dorothée Herr, a preliminary expert on ocean policy, about how to rebalance the ‘green’ and the ‘blue’ in the context of climate change and what research, funding, decisions and developments are needed most to curb the degradation of our waters.
