As hard as I try to avoid thinking about it, I believe we're all in a little denial that the sport we love might have negative impact on the natural world around us.
I don't care for the term "denial" in this context. Or denier. It's loaded with innuendo that's unfair to all of us as a group. Denial suggests we've been shown conclusive proof that we're harming nature by walking in the woods, and we refuse to accept the fact. That's simply not the case, especially as far as this opinion piece is concerned. It's more likely true that we all are aware of the problem, have a reasonable level of concern, and just don't see it as that much of a problem.
Consider the Butterfly Effect, where a butterfly's wings flapping starts a chain of events eventually leading to a hurricane. Perhaps we should just stay inside and play video games. Or write posts here.
It's vital to weigh all the positive things, the benefits that the hiking community brings to the environment. Consider the state of the White Mountains in the 1800s compared to today. There's a great deal of stewardship and care given, and it should be accounted for in any assessment.
I read somewhere, I think it was in The Resilient Earth (great book) that over 99 percent of species in Earth's history have gone extinct. Something to think about. Life on Earth is precarious, and many species are thriving or fading away by no fault of humankind. Should we be thoughtful? Absolutely. Should we get our shorts in a wad over a walk in the woods? Not from what I've seen.
One more wildlife story. My favorite. This happened shortly before my daughter and I went to see the first Harry Potter movie, and if you're familiar with that series, you'll see the relevance. I was mtn biking through a dense grove of cedar and saw a large bird flash by, to my left. Excited, I sped up on the winding trail and tried to catch a glimpse of it again. After a while, I gave up and stopped in the trail to take a breather and get a drink. After a moment, I turned around, and behind me in a tree, about 12 feet away was a Barred Owl perched on a branch about seven feet off the ground. It did the typical owl behavior, moving its head around, and eventually I was compelled to make small talk with it, telling it what an awesome bird it was. Unforgettable. I eventually left it on its own and took off down the trail. Now, of course the Harry Potter books/movies have plenty of owls, so it made it even more "magical." Stay warm, my friends.
