There are things we’ve been doing for almost all of human history almost everywhere that we don’t want to do now…we kept other humans as slaves and we treated women as second class citizens, and we don’t do it anymore. We overcame it, and when we look back at those things that we did, we look back with shame… and I think the farming system we have now… the dominant kind of farming system, the kind that produces 99% of the animals we eat, is something that we are going to look back on with shame.
