I admit to DEET (topical not spray) use and Sunscreen (mine is mostly Titanium Dioxide) but as I rarely swim whilst on a bush walk I don't think I contribute much to pollution other than that which is absorbed then excreted through pee and poo.

I think wisdom and moderation should prevail in all circumstances.
I for one never bush-bash, as I don't feel that my personal enjoyment of exploration justifies the damage I do to the area when I buffalo my way through. But I would never dream of being critical of those who do, as long as they don't leave a lasting trace of their passage.
When I did my grad studies in Natural Resource Management, I studied under four really well-known park managers/designers. Their take on this stuff is that usage must be controlled in such a way as to ensure that the Wilderness is sustainable as an ecosystem, which is pretty much how most of us feel. But when it's broken down into the nuts and bolts of what actually does the damage, some of our most common practices are among the biggest no-no's. For instance, in Alpine and Desert ecosystems, trail-walking is bad, unless on a hardened trail, but if the hardened trail is not water-permeable then it's worse. Bush-bashing is actually better than walking on a dedicated trail, unless you are below the snowline, and is always better in deserts. Running, bike riding and jogging as likewise highly detrimental in many areas, as is skiing and snow-shoeing.
But as with all things, as managers people have to make the decision about how much of the pristine quality they are willing to sacrifice in order to allow access to the bush and still preserve it as "Wilderness," whatever that is nowadays.
It's easy to be arm-chair critics, but none of us really understand what is happening in the Great Outdoors- we may get bits of it, or think we do, but when it comes to the Wilderness, scientists will, or should, tell you that the wisdom of Socrates prevails- the man who knows he knows nothing knows more than anyone else. And while I do truly believe in the Precautionary Principal, a little bit of Sustainability that most folks have forgotten about, I do feel that these things can be carried to ridiculous extremes.
