Pope Francis is genuinely concerned about the poor and environment. The most obvious results of abandoning use of fossil fuels is continued extreme poverty and terrible living conditions for over one billion people in the Third and Fourth World today. It also would mean the return to a way of living in the First and Second World as it was two hundred years ago. Very simple living, human muscle, horse and cattle power, and probably slavery like it existed for hundreds of years. It is unfortunate that this Pope and all the Climate Change Alarmists don't acknowledge that. Many leaders in the great religions of the world don't want those consequences.
