The good news is that what is good for humans is to maintain biodiversity and what's good for biodiversity is good for animals. We are currently deficient in this area, so even if the world was full of big_curses we would still need to make some progress in protecting wildlife, if even for our own selfish reasons.
But you are wrong that animals don't have, or cannot conceive of, having rights and that we don't "owe" them anything. The truth is that we owe all living things the right to exist in the same way your rights are granted by the constitution. It may be a tough to shake off a barbaric mindset like the one expressed above, but if you don't want society to leave you behind, I suggest you try.
