> Well, I filled it in but you're missing the elephant in the room: driving (and/or flying) to the crag. This must be the biggest evironmental impact of climbing by far. And my perception is that people's habits have worsened significantly in this regard. Back in the 80s & 90s I recall mostly driving out on a Friday evening with a full carload of people (usually mine, as I had a large company car at the time).
> These days I'm much more likely to be going out alone to meet somebody at the crag, or at most going with just my climbing partner, Which might just be changes in my personal circumstances & circle of climbing partners, but I have the impression it's more general. And not good.
In reply to AlanLittle:
Thank you for your feedback, I will definitely take this into consideration. I have looked into the pollution side of climbing (regarding transport methods) for my research, and so I appreciate you backing this up for me!
It has been hard to narrow down the worst environmental impacts specific to climbing, and so this questionnaire was mostly relating to physical impacts around the crags and seeing if there are specific differences between trad and sport.
Thank you for your time!
