Probably everyone worried about climate change knows that approximately 50% of greenhouse gas emissions are due to our industrial agriculture system. Picture the huge tractors in the fields, the thousands of miles that semi-trailers travel getting food from the farms to the supermarkets, and the methane from the manure lagoons.
However, probably the most destructive thing (at least equal to the human health problems caused by processed food) has been the killing of the soil. The heavy use of of chemical fertilizers, poisons (pesticides and herbicides), the monoculture crops and GMO seeds is keeping the soil from being the carbon sink it used to be.
