At the UN Oceans Conference, I heard a bold claim from an Australian billionaire: if we turn 30% of the world's ocean into marine protected areas, we can fix the oceans.

This sparked a fascinating conversation with Dr. Fabio Favoretto, an internationally renowned marine scientist who has dedicated his career to researching these protected zones.

What started as an academic discussion turned into one of the most entertaining and eye-opening conversations about ocean conservation.

Dr. Favoretto paints vivid pictures of healthy oceans where the sun goes dark from massive schools of tuna, and of devastated seas that have become underwater deserts. He explains what marine protected areas really are, why they're so controversial, and the surprising obstacles we face in establishing them.Most importantly, this conversation offers hope – because the science shows that when we stop interfering, nature doesn't just survive, it explodes back to life with breathtaking speed.

About FabioDr. Fabio Favoretto – Marine ecologist and internationally renowned scientist specializing in marine protected areas research. With over 4,000 dives around the world, Dr. Favoretto has conducted groundbreaking research at Mexico's Revillagigedo Archipelago and works to demonstrate how ocean protection benefits both marine ecosystems and fishing communities.

Key Quotes”The sun darkened. Everything went and I could feel the movement of the water because thousands of tunas were like just going… you could see like, like basically Formula One cars.” – Dr. Favoretto describing an encounter at Revillagigedo

”That was stolen from me. I could have dove with mantas, white sharks, turtles, seals… I could have dove in the Mediterranean Sea, and I cannot anymore.” – On the degradation of the Mediterranean

”The ocean is not dying. The ocean will never die… We are the ones that are paying the price, but we are not realizing it.”

”We can do almost whatever we want with 97% of the ocean. So what are we talking about? We are really fighting about the 3%.”

”It's either protect or go extinct.”
