The three pillars of veganism are:

1. Compassion for all animals (i.e. an understanding that there is no difference between a chicken or a dog, a calf, or a cat).
2. The concern and care for environmental issues (i.e. massive land use and pollution caused by life stock farming, pesticides, antibiotics, etc.); and
3. The positive effects on health (i.e., low cholesterol, no lactose intolerance, a pure conscience, etc.).
