"To never breathe fresh air again."
can that air and bring it with you (you ever heard of "perri-air"?)
to never jump into a river or hike in woods again"
on earth the rivers are polluted and the woods are full of ornery bears and exhibitionists. mars is at least pollution and freak-free...
"To never go for an early morning jog or play a game of baseball in a park."
on mars you could jog without the fear of being run over by some nitwit chick in a taffeta white honda civic texting on a smart phone with one hand while putting on her fuggs with the other...
"or play a game of baseball in a park."
on mars there will be no situation where you stumble by a family friendly playground area shagging a errant grounder and get taken for a pedo and tased by an undercover cop.
"No way I would ever give up Earth for the barren frozen waste that is Mars."
one man's barren frozen waste is another man's interplanetary version of walden pond.
