Episode 1 - Can Seaweed Really Save the Planet?
Hosted by: Dr. Michelle Tigchelaar, Senior Scientist and Climate & Environment Lead | WorldFish
Seaweed is being hailed as a game-changer for food security, climate action, and even plastics replacement. But does the science back up the claims? We talk to scientists and experts exploring seaweed’s potential, from researchers studying its role in ecosystems to those working on practical solutions for scaling it up and ask, can seaweed really change the world?

Episode 2 - Can Fish Fix the Global Nutrition Crisis?
Hosted by: Dr. Wanjiku Gichohi, Senior Scientist and Nutrition Lead | WorldFish
Nearly 800 million people still go to bed hungry every night, and millions more are missing the vital nutrients needed for growth and health. Fish and other aquatic foods are among the most nutrient-dense foods on the planet, yet access, affordability, and policy gaps keep them out of reach for many. In this episode of The Deep Dive, we test the promise of fish against the realities of price, distribution, and culture and ask, can fish really help fix the global nutrition crisis?
