Recently I've been in phases where don't buy anything to eat at all and am in one such phase now. If anything causes more harm to animals than another food, then I want to eat the food that causes the least harm. The thing is I don't know what food does cause the least harm. I had figured at least that potatoes would be more ethical to eat than any food derived from grain because I know that lots of animals live on grain and so a greater number of them would be killed over the time covering preparing the land for planting/seeding to the food reaching the consumer, with the greatest numbers of 'higher' animals killed during harvest of grain/graincrops and in protecting harvested grain/graincrops during storage. But then I came to the dilemma of whether it would be most vegan to eat organic or non-organic potatoes, and whether there was food that would be more ethical to consume (cause less harm) than potatoes. And now once again I'm at amiss as to what to do, and now that all my unreturnable food has run out I am not eating or buying anything presently until I can decide the best course of action.
