Rock climbers in Ontario tend to be taught quite well in their training about the environment. At least I was. We tend to be quite strict about it to the point of instructing others if their actions are having a negative impact on the environment. It requires some education but that's one thing Canadians tend to be good at.

Though I won't deny we have some gung-ho climbers who don't care. Those guys tend to be shunned by the climbing community and are the kinds of people who have and cause accidents.
