Sustainability is on everyone’s lips. But what is it anyway and what do we have to do with it in concrete terms? Sure, everyone wants to leave an intact environment for their children’s and grandchildren’s generation and would do anything to guarantee this. But why don’t we act like that? Sustainability and the effects of our (non)actions are far too abstract and we freeze before the challenge. The basis for change is understanding and knowledge about alternatives and possibilities of influence. We want to show that everyone can become effective and shape the future.
