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.

Eating meat and dairy products is the SAD (Standard American Diet) diet. The SAD diet can only make you sad. It causes heart disease, cancer, diabetes and makes you fat. Raising animals for food destroys the environment... And those animals are not happy. They are enslaved and live humiliating, fearful lives of abuse and tremendous suffering.
