We are interested in having a better living environment around. To achieve it, we work in different ways, in different sectors, at different scales, individually or collectively. The activities may be focused on global warming, organic farming, pollution, health.... The list is endless. What we basically try to do is trying to bring some change in the attitude or the working nature of the individual or a collective. For example, to bring down industrial pollution, the industries are asked to use right means of handling the pollutants from their industry. For health concerns, the individuals are asked not to use health retarding addictive.
