Recording 11 meters underwater surrounded by hundreds of fish wasn't exactly what I planned when I started this podcast. But here I am, sitting in Grant Romundt's revolutionary SeaPod off the coast of Panama, discovering how Ocean Builders is solving humanity's space crisis one floating home at a time.

Grant's vision is simple yet mind-blowing: instead of destroying marine habitats, why not create them? Every SeaPod becomes an artificial reef, turning empty ocean into thriving ecosystems. With smart toilets that work better than most land-based systems, AI brains cooled by liquid, and jet ski elevators that sound straight out of The Jetsons, these aren't just homes - they're glimpses into how we might live when floating cities become as normal as suburbs.

The best part? Grant believes we'll see entire floating cities within 10 years. And after spending time in this underwater room watching fish swim by my window, I'm starting to think the ocean might just be humanity's next frontier.

What if you could feel like a whale or walk with elephants without leaving your city?

Ulrico Grech-Cumbo uses VR to create "empathy at scale" - making millions feel connected to nature through experiences that trick your body into believing you're actually in the wild.

We explore how XR might replace zoos, why virtual nature creates real physical responses, and whether digital experiences can solve our disconnection from the natural world.

From filming lions in 360° to building "zoos of the future," this challenges everything about conservation.

Is this the future of saving our planet, or just fancy nature documentaries that keep us indoors?
