It is well-known that a vegetarian diet is far more efficient in utilising resources: a pound of meat uses up a hundred times as much energy and water as a pound of vegetable matter. When you eat vegeies, your body eliminated the unwanted waste quickly; meat remains in your system far longer and putrifies. Imagine if everyone was vegetarian, there would be no need for deep sea trawlers devastating the oceanic ecosystems. Forest would not need to be cleared for grazing pastures or to grow grains to feed the cattle. One visit to a slaughterhouse will make you puke your guts out - the filth that the animals live in and the filth that they feed on... most animals commercially bred for meat live short lived lives suffering from innumerable diseases. They dont live in the fashion nature intended them to. And when you mess with nature, you pay the price..
