Environmentally friendly is what you see envivonmentally as. If you seee that burning a tree or paper is bad because it puts CO2 in the environment, you probably wont last so long. If you see that littering is bad, you are quite a bit smarted because in an emergency situation, NOTHING is trash, unless it is a cheap/ripped back pack! (and toilet paper, unless-- I know its nasty but if it is used and you have a bag available, use it as tinder or kindling. it would probably stink though!!

Anyone elses view on this^?
