People eat animals that eat plants. If we just eliminate that middle step and eat plants directly, we would diminish our carbon footprint, decrease agricultural land usage, eliminate health risks associated with red meat and alleviate ethical concerns over animal welfare. For many of us, the major hurdle to executing this plan is that meat tastes good. Really good. By contrast, a veggie burger tastes like, well, a veggie burger. It does not satisfy the craving because it does not look, smell or taste like beef. It does not bleed like beef.
