I've certainly never considered, or proposed, that trad climbing 'leaves no trace' ... But it certainly is about 'place your own and leave no gear' ...
If you want to be pedantic the only way to really 'leave no trace' is to actually not even go ...
Also regarding rock wear and damage, that also happens quite naturally due to weather and is how cliffs are formed. They do not naturally have bits of metal glued in them! |
