I had a long chat with a full-on vegan a while back. She was a lecturer on a philosophy course I was doing, an ordained priest and a very interesting person! Based on what she said, it seemed to me that veganism was a very difficult set of philosophical and practical principles to live by, and that a strictly vegan world would seem a very strange place to most of us. It's not just what you eat: there would be no domestic animals, no pets, no exploiting bees by putting them in hives and exploiting them as pollinators, so no honey, and definitely no insecticides, fungicides or herbicides etc. etc. etc. It struck me it would be almost impossible for the great mass of humanity in the world today to live a truly vegan lifestyle and not starve. I thing vegetarianism has more chance of success. Veganism strikes me as a western middle-class affectation.
