In the November 13, 2017 issue of the journal Proceedings of the National Academy of Sciences Robin R. White and Mary Beth Hall attempt to establish why a hypothetical vegan world is not possible. Their findings do show a decrease in greenhouse gas emissions, but they argue that a diet without animals or any kind of supplementation would be nutritionally deficient. Our mission at the Humane Party and specifically in the Economic Transition Team is to create a United States agriculture and economy 100% free of animal exploitation.
