More than 50 years ago, explorer Jacques Cousteau introduced millions of viewers to the marvels of the undersea world. In 2021, the ESG world is increasingly focused on biodiversity, and the oceans are a big part of that picture. Goods and services from the world's oceans and coasts are worth at least $2.5 trillion annually, while the overall value of the ocean as an asset is at least 10 times that amount, according to a 2015 estimate from the WWF.

In this week's episode, we interview Cousteau's grandson, Philippe, the co-founder of a nonprofit called EarthEcho International that works on ocean health.

"It's important to start thinking about a restoration ethic and returning the oceans to abundance," says Philippe. "For far too long, the environmental movement has been a movement of deprivation and doom and gloom. It has not been enough of a movement of opportunity and hope."

We also hear from Doug Heske, CEO of impact investing company Newday Impact that has teamed up with Philippe to promote ocean restoration, especially among younger investors. And we interview fund manager Paul Buchwitz from one of Germany's largest asset managers, DWS, about how the company is aiming to ocean-related risks while tapping into new investment opportunities offered by ocean restoration projects.
