What matters

"It doesn't take a genius to see that an ever-growing population cannot continue to devote limited resources to produce ever-increasing amounts of meat, which takes roughly 10 times more energy to produce than plants. Nor can you possibly be 'nice' to animals, or respectful of them, when you're raising and killing them by the billions.

"And it doesn't take a scientist, either, to know that a handful of peanuts is better for you than a Snickers bar, that food left closer to its natural state is more nutritious than food that has been refined to within an inch of its life, and that eating unprecedented quantities of animals who have been drugged and generally mistreated their entire lives isn't good for you..."
