Personally I eat meat, though not very often. This is consistent with a lot of humans throughout history and it's very easy to maintain a healthy diet doing it. It's what I would advocate as the next step. As I see it, advocating for veganism is a little like advocating for communism. It might be something that is easily possible in the distant future, but we need to take steps if we wish to one day get there. It would be a radical reorganization of the food industry to shift to my diet, much less a fully vegetarian one.
