Well I've seen in the space of ten years a massive attack on coal and oil production, with a branching out to solar and wind power, not enough to make much difference yet, but the wheels have been put in motion, by the time the rest of the climate change scientists come to realize that 50% of the Global warming precursors have to do, not with energy, but with factory farming for meat production, you're going to be having massive amounts of climate change scientists and government officials clamouring to reduce meat consumption, as well as the consumption of coal and oil. And as these forums make bitterly obvious taking away peoples meat is about as easy as banning their firearms so it will probably be accomplished in the form of making people pay the actual costs of their meats production which is going to get a lot more expensive as land, water, and farming costs go up.
