its not permanent. Plus, its nothing to do with environmental issues. Lets not confuse ourselves, this isn't the environment we are discussing, this is arm chair climbers with a stick up their ass about the colour 'white' blotting their favourite climbs.

No link. Limestone climbing even in moderate use leads to polishing of the rock, far more damaging than mag carbonate that washes away..yet noone pushed this argument... why? Chalks an easy target for those who like to think of themselves as better than others, 'I don't need chalk, why should you?'

It's not permanent. Maybe, just maybe you have found the singular cases in which it is, but as a general discussion I would love you to enlighten us. Afterall we are talking about chalk use as a whole. Again, I just don't see it as a problem. Sometimes there is chalk on the rock, next time I see it it's gone, as if by magic. The odd roof or boulder problem provides the exception... is this what these wannabe environmentalists are all caught up with? I hope not!
I have never in 7 years of climbing seen holds destroyed because of chalk, especially compared to that of chipping. I have seen polished holds, I have seen polished holds covered in chalk...are you sure you are not confusing this combination for permanent damage? This my friend, is a natural consequence of us all going climbing, not chalk use.
