Is litter getting worse? Are thru-hikers littering more than they used to?
I recently have done three section hikes on the PCT and I was amazed at the litter. I encountered toilet paper (and could smell the dooky) on the trail, bits of electrical wire left like some kind of breadcrumb trail, wrappers sometimes obviously freshly dropped. I've seen used maps and pages from guide books left as trash, plastic bags, foam rubber, odds and ends. You name it. This isn't near road crossings but out in the sections of the trail far from roads and often in places that are too ugly or boring for ordinary weekend hikers to be.
I've also heard reports of trail angels finding big piles of trash that they've cleaned up at places where hikers gather. It's obviously hiker trash because of the maps and guide book pages.
I don't remember it being this bad even a few years ago. Are people littering more than they used to? Does anyone have any tried-and-true suggestions for educating hikers about littering? They obviously don't read laments on the internet so it seems some kind of in-person or on-trail intervention is needed.
