Of course it could work! Jeesh! (Score 1)

Why is it people seem to be so cynical? What are we on earth right now but 'stuck in a tin can for your entire life'? How would someone born on a generation ship have any reason to complain? What would they be comparing to? Pictures of mother Earth? Really, how many people have tried to destroy the world? Why would anyone do that on a spaceship if not on Earth? We're not any less trapped or isolated or stuck right now! A generation ship would need its own aritificial climates in order to scrub the air, clean the water, grow the food, and provide respite for the populace; if we can solve the artificial gravity problem, I would imagine snow, rain, floods, sunshine, and all other manner of weather for variety.
Likewise landscapes would be varied among scrublands, mountains, fields, marshes, etc for all their various technical and psychological uses. I dunno, I think it would work!
