This is what I don't get about the human race. We can send people to the moon, yet can't figure out how to build a giant climate control device to cover then entire planet keeping it at a constant 17C all year. Bloody useless species. No wonder aliens don't even bother visiting us.
Well there's something to be said for variety, eh? I've travelled pretty extensively in Asia, Oceania and Europe, and still love experiencing the differences (good and bad). What's the point if everywhere is exactly the same as home?
