except for those who inhabit regions of the world (e.g. the Siberian tundra) where meat is indeed needed to sustain life. And do we make an exception for predator animals? You might want to try persuading a tiger to become vegan! Human beings have evolved as omnivores (look at our teeth and digestive systems). What you are probably saying is that we are able to choose or not to eat meat or exploit animals, but we have to be careful. History and culture shape our eating habits and sudden change can in fact result in ill health and endanger lives.
