This is very well said. From Dr. Lori Marino, of the Kimmela Center For Animal Advocacy, in a compelling deconstruction (via the sad story of two oxen called Bill and Lou) of the belief that meat-eating is in any way sustainable:
The reason the planet and all of its inhabitants are in such a desperate state is because our species has continued to exploit everyone and everything without compassion. Killing other animals reinforces that insensitivity and the very attitudes that have led to global destruction. We are currently facing the sixth mass extinction event, human overpopulation and starvation, and devastating planetary destruction from rampant ecological exploitation and climate change. The same insensitivity that leads to lack of concern for Bill and Lou as individuals has led us to the brink of global devastation. They are intimately related and anyone who claims otherwise is being disingenuous. Every individual currently in factory farms is Bill and Lou and factory farms are not only engines of unspeakable suffering for the luxury wants of our species but are contributing substantially to global warming.
