We are hooked on a meat-centered diet because of the illusion of cheap grain. Over 70% of grain in USA is fed to livestock. This is most inefficient it takes sixteen pounds of grain yield to yield 1 pound of beef. Six pounds of grain produce 1 pound of pork and 3 pounds of grain to produce 1 pound of chicken.
If the whole world were vegetarian there is enough grain to feed 11 billion people. The current population is 6 billion.
The total cattle herd in the world is 1.3 billion head; total weight of the animals exceeds the weight of humans on earth.
Global warming would be reduced considerably if meat consumption were reduced. The contribution to global warming by automobiles is insignificant compared to the use of energy for feedstock.
