Greta the puppet is vegan because the elites don't want the common people polluting their world with methane from animal agriculture once there's no more free market for food. Notice how she doesn't care about sustainable energy or any real innovation? It's all either fluff-talk, photo-optic protests to distract us into accepting the smart grid! Like reeeeally fluffly talk - just hypnotizing us with sounds and hoping we don't notice that the lack of substance, and holding up dumb signs as a front to real activism that could be done.
