The Five Basic Principles of Going Lighter ~ Cam "Swami" Honan of OZ
Yep. Concern for the environment and the ethical implications of supporting, through purchases, certain industries isn't easily navigable. And honestly, I think some degree of it is more virtue signaling, as those of us who buy these products in the first place aren't going to truly change our overall lifestyles that have far greater negative impacts. We humans alter the environment to an incredible degree compared to any other species. When it comes to hiking, we cut trails, fly and drive to those trails, buy manufactured gear and clothing (of any material/fiber source) and heavily processed foods, etc. We live in a technological-industrial world, and I seriously doubt we will return to agrarian societies. The differences in the choices we make regarding hiking don't amount to a gnat's @$$ in the scope of the greater environmental impact we humans (especially us 1st world ones) in general have on the planet's environment or related ethics. If (less ethical?) nylon and down gear keeps you dry and warm so you don't need rescue, you'll save the much greater negative environmental impact of creating a backcountry rescue event. Sorry to be so blunt, but when it comes to ethics and environmental concerns, I think things like more efficient houses and vehicles, building materials, agrichemicals, etc., deserve my attention before I start spending my finite time going down the rabbit hole of ethics when it comes to choices of hiking clothing and gear.
