I'm sorry, but I don't follow where your going with this.
You say that we need to work together to get off of the planet,
But where exactly do you have in mind? We have no idea where
else we can live In the universe, let alone the solar system. We
have people searching, but there is nothing we can do until they
find, and confirm that their is another hospitable terrain.
Anyway, let's say that there is another planet we can live on, and
have found it. Who are the '
we' in the 'we' need to work together?
It's not a feasible reality to 'evacuate' the planet. The only people who
would be allowed off would be those with alot of power or a high socio-
economic stance.
As you said, we don't have much time left. So why not spend the rest
of the time doing what the human race does best? Killing eachother.
