If by breeding less you mean breeding less than the replacement level so that we can get to a "sustainable" size, I think you are wrong. Our sun puts out enough fusion power that, if we could capture a small chunk of it, each of us could personally use the current energy budge of the entire earth. Ultimately population growth at some fixed percentage is unsustainable (population growth at a fixed percentage grows exponentially, our light-cone polynomially), but I don't think earth's current population is.
