this is just stoopid...we've already done so much damage to this planet...
I had no part in the decision making process that led to any significant world or environment damaging, and I doubt you did either, unless you have a hand in directing activities of a industrial company or are involved in military decision making. You may very likely not even know anyone who did. Get it straight, the robber barons and financially powerful that direct the ecologically damaging activities are not "We". Not without contorting the meaning so as to blame the consumers for how the products used are produced. Were "we" dumping agent orange in Vietnam? "We" level mountaintops? Funny, I don't recall getting my share of the profits!
Little known fact: The iconic "Crying Indian" commercial of the 1970's was produced by a consortium of industrial polluters in order to throw the popular focus back on individuals at a time when industrial pollution was an exponentially greater problem. Sure, people threw garbage out their car window, and that's bad, but the cumulative damage from that was a tiny fraction of what industry was doing.
