More rock climbers needed to save the planet

Outdoor climbing has a very small impact on the environment in comparison to other sports where you almost always need to build and maintain an arena. Bouldering and DWS are quite unique and fulfills best the Tyroldeclaration, "We strive to leave no trace". Trad climbers leave environmental trace due to all cams and nuts needed meanwhile sport climbers need less gear but bolts. Moving out people from practicing sports indoor into rock climbing outdoors will in the long run mean less impact on the environment, as less arenas are constructed and required. Getting exposed to the outdoor makes it possibly the former arena sport-persons will develop into ambassadors for the planet's nature. They might also personally reduce their environmental impact and possibly adapt to the low budget/less impact outdoor climber style. By strengthen the local community, which in reality means that more boulders and routes graded 3 - 5 should be developed, the number of rock climbers will increase. More climbs in your neighborhood will also mean travelling will be reduced. Disclaimer - Surely, more climbers could to some extent have a negative impact for the local climbing community in regards respectful behavior and access etc. However, in regards saving the planet, each arena person we could get out in the nature becoming an eco-ambassador the better on a global perspective. The Access Fund is working hard and just published - Climbing Areas Loved to Death and clearly this has a lot to do with access education. We do all need to interact on the scene...not just posting negative comments in forums.
