college isn’t going to teach you “how to live off the land.”
so why are you taking up the space of someone who would really like to use the college education.
living off the land does not provide you with anything to invest, so you can scratch that off your list.
living off the land and conservation are not related.
if you’re conserving, what are you conserving?
one would presume you’d want good water anyway, so it wouldn’t do you a lot of good to waste, or pollute it.
on the other hand, if you really are considering using that college education, maybe you want to think about what’s needed in cities to conserve and minimize resource usage.
