Just keep in mind urbansurvivalist, there is an awful lot of land that is privately owned. People can do whatever the heck they want with it as long as it doesn't break the law. How would a person be expected to take such a question/statement on their environmental ethic if they were practicing their survival skills on their own property? Think about it.
If I owned a hundred acres of woods, and I know people that own that much and much more, I would say "It's my property." Heck, they're clearing entire forests again for hardwood alot in the last 10 years here in TN anyway, just for the cash. The woods next to your yard can be there one day and gone the next.
I do believe and practice the ethic of leaving no trace and taking only memories with me, but not everyone is a so-called "tree-hugger."
Locally here, groups have started to adopt stretches of river like stretches of highway to clean up litter and such. Man, it sure needs it. I am just starting to look into this program.
