Divine Malevolence as Demonstrated by Trophic Efficiency
As most of you know, we live in a reality where you have to kill and eat other living organisms to survive. That sort of ghastly behaviour can really only be explained by a malevolent deity to begin with, but it's worse than even that.
Trophic Efficiency is a measure of how effective biological systems are at moving energy through the ecosystem. It's at about 10% per energy transfer. That means that it takes 1000 calories of grass to make 100 calories of cow, to make 10 calories of human, to make 1 calorie of grave worms.
So not only do you have to kill and eat other living creatures to survive, you have to kill ten times as many! This sort of gruesome mess can only be reconciled with a particularly hateful god.
