I don't see pests listed in the above discussion, although I could have missed it. However this is as big as drought, if not larger. Not just insects, rodents, bird cyclictic overpopulation wiping out crops, but also fungus, bacteria, etc. The world has starved more than once from such things, and the Egyptians had reverence for cats for a reason.
