re: Don't you know that you can count me in.
Unlike other organisms which are controlled by biological constraints, humans can continue to multiply and consume without limit
And we have no biological constraints?
Even if we were to "consume without limit" biological constraints are present. Reproduction rates, sterility, food, survival of the fittest, etcetera. Whether cannibalism would emerge on a world with no animals besides humans or whether man would develop technologically to such a degree that a handful of dirt could be turned into a nutritious meal - biological constraints would come into play - just as they play out now.
You're not a human-hater ER. You're drawn and compelled by the dark side of the force, but when given the necessary 4 dimensional perspective you will side with a blossoming humanity.
