I do believe him with what he says about the grasslands, but he is in agreement that burning fossil fuels cause global warming. Which I don't agree with. I guess that is due to some of his college indoctrination. We need more CO2 not less. the more CO2 there is the more fruit and vegetables plants produce, and they do it with less water. Plants need CO2 and the environmentalists want to get rid of it.
I guess the environmentalists need some reason to get rid of people, and the new world order people need an excuse to transfer wealth. What better reason for both than to claim that humans and cattle are destroying the earth and causing it to heat up.
