>... CM's imagined scenario of a society that's eating itself is far from real evidence we have seen of humans. Real evidence shows that during catastrophic moments like earthquakes and prolonged famine and even war, human societies have shown remarkable strength to save and to protect and to help one another, sometimes at great individual sacrifice.

This is very tangential, but this is one of the reasons I could never get into The Walking Dead and similar shows. It was really hard for me to suspend my disbelief there.
