Animal populations drop dramatically as a result.
It's sad, but we need not go into denial over it. Keep those terms in mind, because they certainly play a major role in the production of this hysterically nonsensical book. It hurts your feet, but you learn something from it. Give it a try. I'm still not totally convinced it's not a hoax.
