Our previous episode was on merfolk (mermaid/merman), but what if the human race doesn’t have time to evolve before the glaciers melt and we are all underwater. What should we do? We need to get moving on building underwater cities, is what I say. This week we go over all the essentials for your underwater habitat: Where it should be located (not too deep, not too shallow), how to make oxygen, ways to generate your own energy, what to grow in your aquatic farm, the importance of desalinization, and of course, what safety protocols should be in place for the inevitable giant shark attack.
