Using Greta Thunberg's campaign as point of departure for this project, we want to explore what our contribution to a greener world could be (inside and outside of schools). We are going to discuss environmental problems in our home regions. In transnational groups of student activists we want to be united as Europeans by a common desire for clean air and an unspoilt environment. This challenge is not easily tackled because very few are actually prepared to sacrifice habits or luxury for that. We will try to suggest solutions and present them at the end of our project. Furthermore, we will have a look at the limits of protest, i.e. what can be achieved and/or what is acceptable.
