It really is a good read, not just on the 'circle of life' thing, something has to die for something else to live etc, but also on the sustainability of cereal crops ( or lack of it). I genuinely believe that a desire to prevent and reduce suffering in animals is morally the right thing to do, but better animal husbandry, is the way to go, ban CAFO's etc. the vegan/ vegetarian ethic strives to protect those creatures that are 'like' us, they have a face, but ignores the millions of deaths that occur at the hands of the combine harvester, pesticides,fencing, habitat destruction, soil erosion and the other horrors of farming commodity crops and annuals.
