- Using a piece of land to grow crops provides fourteen times as much food as using the same land to grow fodder for animals
- Plants from each acre of land provide 800,000 calories of energy but when these plants are used to raise animals which are then eaten as food, animal meat can only provide 200,000 calories of energy. So, 600,000 energy calories are lost
- Consequently, the math reveals that a vegetarian diet is more efficient and economical than a meat based diet
