    The human brain requires a relatively huge percentage of energy to work. Most plants aren’t calorie dense enough to get the job done; vegetarianism is a modern luxury.

        Veganism is a luxury afforded to us who have access to vast amounts of fresh produce all year.

        Even 100 years ago I don’t think being vegan would have been possible year round, as it would be nearly impossible to get the variety of produce needed to sustain a person in the winter months.
