personally... I think all of the countries of the world should put money into NASA, or a space agency with all of the worlds powers...well, a lot more than they do. that way, the resources and money would be amazing. seriously, it's not like the US is going to be able to expand into space all by themselves, however they're the only ones that seem to be taking it seriously compared to others.
i don't know if it's too early to be looking into the future like that or not, but at some point it's going to have to happen.. better sooner than later. we can't just sit around and think about ourselves, it's the future we have to think about and the answer isn't "let them worry about it".
we fix problems here on earth every day, this is just an excuse to not do something. besides, this is for advancement... not fixing.I think before we start throwing money at NASA so we can travel into space better, we should fix some of our problems here on Earth.
