Sounds ambitious, but if we can’t even fix our own water problems, how are we going to do it on the moon?

A self-growing city sounds cool, but I’m just wondering who’s going to pay the water bill out there!

A moon city is great and all, but I’m more curious about how they'll handle the moon’s lack of fast food joints!

Sure, building on the moon could be fun, but I hope they consider moon dust allergies!
