Because we MUST find a way to move from this planet to ensure the survival of the human race, Mars is a stepping stone if you like. Our star has a finite lifetime so moving is absolutely necessary.
from NASA ..
A star like the Sun has about 11 billion years of life before the white dwarf stage. It has already gone through 4.5 billion years so that leaves about 6.5 billion ...
Unless, of course, you just resign yourself to the fact that the earth will end eventually (it will) and you don't give a toss about what will happen to our descendants because you won't be here to see it.
of course I care .. but I believe God .. mankind as human only has a little over 1000 yrs left anyway, and God has said He will be here with us during that period .. and after that, He will create a new heavens and earth .. so where ever we went would just be a waste of time ..
The fact that we don't take care of the needs of everyone on the planet is entirely political. Population control is an absolute necessity in my opinion. If we don't control it then nature will I'm sure.
man's inhumanity to man perhaps is a part of nature ..
