The raising of animals for food and all that it entails is the single most destructive force impacting our planet's fragile ecosystems. Our planet simply cannot sustain the greed of billions of human beings who are eating other animals.

Raising crops to feed animals for human consumption requires a lot of land. It takes eight or nine cows a year to feed one average meat eater; each cow eats one acre of green plants, soybeans and corn per year; so it takes eight or nine acres of plants a year to feed one meat eater, compared with only half an acre to feed one vegetarian.

Have you seen how fish are able to swim in a school so precisely relating to their fish-fellows and never clumsily bump into one another? That's because they have a highly developed sense of feeling in their bodies, which enables them to feel not only the movement of the water against their skin but the presence of other beings who are close. They certainly are not cold-blooded in the sense that they are dull, insensitive, and have no feelings.

The fact is that eating meat and dairy is bad for your health, the health of the animals eaten, as well as the health of the planet.

Cows that are fed organic food are still kept as slaves on farms, regardless of whether it is a large corporate factory farm or a small family farm. Besides, every dairy cow, no matter what she has been fed, has her babies stolen from her shortly after birth and she will inevitably end up in the slaughterhouse.

What could be more physical than what you eat, where you live, and who you live with? These are all very physical issues.

We create the world we live in. If we want to change what we don't like in the world, we must start by changing what we don't like about ourselves.
