The plain truth is that these people, the rich, the ruling classes have made it ABUNDANTLY clear that they do not care whether you live or die. That they have EVERY intention of driving us right off the ecological cliff to maintain their power and wealth. That they are not going to stop no matter how much you beg them to.
So you must make them. Maybe you can do that politically, but it sure as shit won't be through parties that WORK for the rich people. One way or another, you must FORCE it.
