Dealing with change, some people often jump head-on from one extreme (total ignorance) to another (hate and humiliation), something that you read at the beginning of this module in the importance of community. Hostility only gives rise to more hostility, and people who are targets of the insults and aggression see extreme activists as fanatics and want to join eco-movement even less.
Therefore, the cultivation of a reasonable attitude is a must. We want to stop global warming to preserve the planet for all species, including humans, why then in pursuit of it we become so hostile to the point of endangering the safety of our own species with our attitudes? How far can we go like this?
