I have big feet (well, one big foot, one regular sized foot now), so I leave one hell of a footprint.
But seriously, like I've posted before, this "leave no trace" is taking things too far. Just like I think "ultralight"-ing is taking things too far. It starts with a good idea and carries it to an extreme, which ends up being as bad as the other extreme they seem to be reacting to.
When I go into the woods, I live there. I live there as a human, not an animal. Humans (most of us anyway) do not have thick fur -- we need something to keep warm. We can't eat raw foods with abandon like canines and such. Fire takes care of both of these needs. It also takes stuff out of the forest that is just tinder for a forest fire -- "mother" nature's way of clearing it out. Yeah, "mother" nature can be a real mother. . .
I don't think that anyone here (except Mr. Finkelstein

) goes into the woods with diesel-powered tracklaying ATVs and chainsaws to clearcut and burn 22 acres for campsites. Sure, there's some buffoons that go out and trash a place, and that sure is a danger to the environment when done on a large scale. However, humans should leave some trace of their passing. We're meant to be in the environment, we're meant to change things, to tame them.
Untamed nature is a hostile and brutal place. Sorry to grind people's gears, but nature is not friendly. Ever listen at night to a deer screaming as the living flesh is ripped from it's bones by coyotes because it got its antlers stuck in some branches and couldn't get out? Ever just sit and watch cute, fuzzy little squirrels run in and raid another squirrel's home and kill its young to remove the competition? Or maybe how many animals were killed by a runaway fire from a lightning strike? All natural occurrences, all happen on a common basis.
Humans going into the woods and using deadfall and such for fires removes them as forest fire hazards. Humans going in the woods and killing animals for food, reduces the competition and actually improves things for the local animal population. A well-hunted (not over-hunted) area of say, deer, will show larger and healthier specimens with a much lower winter mortality rate than one that is not hunted at all. In fact, the area not hunted is usually worse off in terms of naturally occurring die-offs and starving, diseased animals than over hunted areas.
Trees that are large and old and in the process of dying are sapping nutrients and possibly sunlight from younger trees and plants, and are better off being felled. Yes, we all love an old, majestic tree. But once it reaches a certain point, it has to go. Smaller trees or weeds may have to go because they are sucking up nutrients from larger, healthier plants, and have no real hope themselves of becoming much of anything because of nutrient and sunlight competition, and are better off being cut down. Yes, I'm talking cutting down live trees.
Humans do this. Humans have to do this, because we are the only animals that aren't preprogrammed to run on instinct. We learn, adapt, and dominate. Animals don't have the cognitive abilities to decide which tree needs to come down, or how many of its prey to kill before moving on. Humans decide that. When we play our part properly, the human impact has a lasting, positive effect on the entire environment.
I have equal disdain for both extremes -- both the "to hell with the world, I'm making my fortune, the next generation can clean up the mess" point of view as I do the "humans are bad,a nd we should never impact the environment, which is inherently good and perfect, and humans are evil and should die off because humans are evil." point of view.
Usually any situation you look at, the extreme ends of the spectrum are usually wrong.
OK, enough Punishment philosophy. . .for now.
