Top of the predatory food chain. A pure and carnivorous animal with an insatiable appetite. Each day he consumes tens of billions of creatures similar to himself. Creatures with brains, hearts, lungs, mouthes and rectums. Creatures who also must breathe, eat, reproduce and defecate. It's OK right now...the population of the planet is 7,000,000,000. What will he do when the population is 30,000,000,000 or 40,000,000,000 Did you know that the cattle feed pens and slaughter houses have thousands of tons of blood and guts and shit and piss which accumulates in small tributaries and ultimately finds it's way back into rivers which supply drinking water for nearby towns and cities That tricky phrase in the bible which grants him dominion over all other beings might prove to have been a bit incomplete.
