Nowadays, the feeling that our civilisation must take a turn is widely shared. Our association, Mountain Riders, would like to see a mountain and a society that reflects the deeper values of human nature. We want to encourage and accelerate ecological, social and economic transition. This eco guide, the green snowflake standard, our work and that of many others, strives to reach one goal: To organise our work and direct our energy towards finding the best solutions to solve the « rubixcubian » brain teaser of sustainable development. And we can only do this with your support.
