Perhaps in the back of our minds we already understand, without all the science I've discussed, that something terribly wrong is happening. Our sustenance now comes from misery. We know that if someone offers to show us a film on how our meat is produced, it will be a horror film. We perhaps know more than we care to admit, keeping it down in the dark places of our memory-- disavowed. When we eat factory-farmed meat we live, literally, on tortured flesh. Increasingly, that tortured flesh is becoming our own.
Needless to say, jamming deformed, drugged, overstressed birds together in a filthy, waste-coated room is not very healthy. Beyond deformities, eye damage, blindness, bacterial infections of bones, slipped vertebrae, paralysis, internal bleeding, anemia, slipped tendons, twisted lower legs and necks, respiratory diseases, and weakened immune systems are frequent and long-standing problems on factory farms.
This brings me back to the image of Kafka standing before a fish in the Berlin aquarium, a fish on which his gaze fell in a newly found peace after he decided not to eat animals. Kafka recognized that fish as a member of his invisible family- not as his equal, of course, but as another being that was his concern.
Elsewhere the paper notes that vegetarians and vegans (including athletes) 'meet and exceed requirements' for protein. And, to render the whole we-should-worry-about-getting-enough-protein-and-therefore-eat-meat idea even more useless, other data suggests that excess animal protein intake is linked with osteoporosis, kidney disease, calcium stones in the urinary tract, and some cancers. Despite some persistent confusion, it is clear that vegetarians and vegans tend to have more optimal protein consumption than omnivores.
