Abstract
We compare the energy consumption of animal- and plant-based diets,
and, more broadly, the range of energetic planetary footprints
spanned by reasonable dietary choices. We demonstrate that the
greenhouse gas emissions of various diets varies by as much as the
difference between owning an average sedan versus a Sport Utility
Vehicle under typical driving conditions. We conclude with a brief
review of the safety of plant-based diets, and find no reasons for
concern.
