You speak only for yourself.
I disagree.
I don't speak only for myself when I refer to the "lazyness" of hikers. I don't at all mean it in a derogatory manner in any way; I am fully aware that for most, the choice to "take the path of least resistance" is not a conscious one. But it is still the choice that is made by the majority of the hiking community, without any of them even realizing it.
It's just one part of a larger concept that is often used by recreation resource managers to try to predict exactly how visitors will behave in the backcountry that is called the "stress-coping model." The basic idea behind the model is that visits to the backcountry are actually extremely stressful for many people- and they'll employ a wide variety of techniques to try to "cope" with that stress. Unfortunately, many of those techniques to cope result in increased levels of impact.
To link it back to the microspikes issue, you can view it like this: A user wearing microspikes comes upon a part of the trail free of snow. The idea of taking their spikes off, and then putting them back on a few minutes later, is inconvenient and causes stress... so they cope by choosing to leave the microspikes on. As a result, their impact is heightened because of the spikes digging into the ground.
I'm not just making this up, or pulling it out of my rear-end. There has been a
lot of research into the idea of stress and coping in recreational and leisure activities. A search on google scholar for published scholarly journal articles and papers on the subject yields
more than 58,000 results.
For the past few billion years, mountains have been rising up, and mountains have been wearing down, and I suspect that process will continue for eons to come. Just one bulldozer creating a parking lot for one Wal-Mart alters the earth far more than all the hikers wear & tear in North America.
Let's keep things in perspective.
I would bet money that the impact that has been created by hikers all across North America, when added up, is far greater than a single Walmart Parking Lot.
Take the Adirondacks, for example. There are more than 2,000 miles of trails in the Adirondack Park. Lets assume that each trail has an average width of 3 feet (the typical impacted area of the trail). I'd say that's a pretty reasonable assumption. Simple math tells us that Adirondack trails therefore cover
at least 727 acres of land- that's 727 acres of potential soil compaction and erosion. For reference, the footprint of a walmart parking lot is usually "at well over 18 acres" (
source), roughly 2.5% of that total. And that's just the Adirondacks! If we conservatively estimate the length of the PCT and the AT at 2,000 miles each, our total rises to 2,181 acres, more than 120 times the size of our single 18 acre parking lot. And we're just getting started- there's still thousands and thousands of miles of trails to consider, and then we can start adding the impacted area of campsites too!
(Of course, we can argue semantics- does a square foot of trail have the same impact as a square foot of parking lot? Probably not. Some really neat things are being done with newly constructed parking lots to minimize their impact too, though: Permeable asphalt that allows water to flow through the pavement, drainage catch basins that use artificial wetlands to treat 20% of the runoff [by treating the first 20% of the runoff from a rainfall event, you can treat 80% of the pollution!], etc. It's really interesting stuff.
)
One of the greatest threats to wilderness and recreation resources is often the people who love and fight to protect them, simply because they use them. Many people unfortunately falsely believe that because they love something, they can do no harm to it. As I stated before, this was a serious issue back in the 60's, when it became apparent that people were "loving the woods to death," and something needed to be done.
Just because, when "put into perspective," our impact as hikers seems insignificant when compared with other impacts we have on this planet, doesn't mean that it really is insignificant, nor does it free us from taking responsibility for that impact. You wouldn't argue that because so many recyclable cans and plastic bottles end up in our landfills, that it doesn't matter if you don't recycle just that one can (at least, you shouldn't be arguing that!
). Every little bit helps.
And finally, one of the values we place upon our wild areas is that they are
supposed to have a minimum of impact by humans. One of the things that makes wilderness "wild" is that
we choose to ignore the "bigger picture," and insist upon as wild a state as possible!
