Didn't they do this on Futurama?

Or Total Recall?  Scientists watch way too much TV.
Apparently scientists are proposing sending old people away, out into space, never to return.
Scientists, worried Earth will become uninhabitable due to the left's favorite existential threat, global warming, are suggesting one-way trips to Mars to colonize the Red Planet. 
"'You would send a little bit older folks, around 60 or something like that'...  That's because the mission would undoubtedly reduce a person's lifespan, from a lack of medical care and exposure to radiation.  That radiation would also damage human reproductive organs, so sending people of childbearing age is not a good idea... 
Still, [scientists believe] many people would be willing to make the sacrifice.
The Mars base would offer humanity a 'lifeboat' in the event Earth becomes uninhabitable."
It would be pretty wild to visit Mars, though.
