We will look back at eating meat the same way we look back on the biggest atrocities mankind has committed. The mass slaughter of living animals and the ripping of animal flesh with our teeth is barbaric. We are blind to this because it has became normal in our culture. If I could buy futures on man-kinds repudiation of animal slaughter, I would. Killing anything that is not invasive is not cool, moral, or necessary. The advent of lab-grown meats or other proteins could do the job.
I am guilty of eating meat until popular culture catches up.
