Hmm... Mr. Simon might want to rethink his logic, because if he is supposed to be morally consistent, he must encourage the extinction of the most invasive species on the planet: humanity. Surely the increase in population from under a billion up through 7 billion in the past couple centuries alone, with all of them exhaling CO2 and most burning fossil fuels, must be one of the causes of all this environmental chaos, according to his logic.
Either that, or he just has a lust for power and inflluence, which I suspect is more likely.
