Meat is produced at the expense of grain, which we might eat ourselves.

And the production of meat is a very wasteful process.

Grains have a fuel value for man approximating 1,600 calories per pound.

A pound of meat in the form of beef will require the consumption by the animal of some fourteen pounds of grain.

The pound of beef will furnish perhaps 1,200 calories, while the grain consumed will represent over 20,000 calories.
