All livestock and manure cause <4% of the average American's emissions (bottom chart): http://css.umich.edu/factsheets/carbon-footprint-factsheet http://css.umich.edu/factsheets/carbon-footprint-factsheet The emissions from grains etc add up to roughly as much overall- you don't eat the entire plant and it either rots or gets fed to cows. Obviously reducing emissions in our food industry is a huge win- eliminating red meat would be awesome. It's nowhere near good enough. Fossil fuels are 30x more important, easily.
