Also they need to change the weather so it never rains or snows and is always warm but not too warm.

I love when people say stuff like this. It’s the “I’m not even going to try” comment. If children in Finland can bike to school in the winter, I think your adult self can deal with a little bit of not-ideal weather sometimes. You just have to dress for it, and not expect to always be isolated from the environment like some people want to be for some reason.
