Eaiting dirt cookies is better than eating plants, animals and rocks. You don't have to kill to eat.
Wait? Do people actually eat dirt cookies? Am I the only person who has never heard of this? I'm guessing they're not healthy, however, shouldn't they appear in mainstream media?
There are videos on youtube, yes many people eat it to survive.

Yum! Dirt cookies are always my favorite snack, but you really can't live on them alone. Rocks however, you can almost eat rocks all day, some sand on top of it as a garnish, just the best taste in the world!
