You see, the reason for global warming and depleting resourses is because we have not figured out how to renew resorses. If everyone in the world would put their ideas together ans stop this senseless fighting and war, then maybe progress can be made.
Doing that to a planet is way to far difficult to be successful today with our technology.
Today, it would take months or years to merely get to mars more and less Jupiter or further. Once we get over the first hump, faster progress can be made.
If we can conquer and master our planet, then we can THINK about conquering our solar system.
I'm sure someone will possibly disagree, but I stand by what I say. If I'm wrong, I will then stand corrected.
