The environmental issue is usually addressed from a cost on abatement / preservation perspective. But to effectively conserve the environment, we haveto be actually willing to do so, which might not always be the case. In the present work, I address the polluting problem from a "political" point of view. Is it possible to reach a sufficient amount of pepale who are actually willing to sustain a good environment quality ? Or will we always be in a state dominated by the less environmentally aware people ? With the help of a simple model, we will find that the result depends, amongst others, on the initial state and on some possible psychological aspects.
