Man belongs to the world, the opposite is not true.

"It was within his grasp to destroy the entire world and to trample all our futures into the dust but he saw the light before it was too late and pulled back. He pulled back and gave the rest of us our chance. He showed us all how it had to be done if the world was to go on being a garden forever. Man was the role model for us all!"
It is a quote from Ishmael, after the narrator makes his revelation. The revelation being that it is not the human races place to control the world. The human race is merely an equal of all other species, we just got a big head because we were the first to evolve higher thought. It was like the human race did not stop to think that all species are evolving and maybe in time some of the other species will begin to develop higher thought. Instead the human race claimed itself the rulers of the planet. The point being that mankind was not, is not the ultimate goal of evolution, in fact evolution has no goal, unless we stop it, it will continue as long as there is variation among a species and time. Unfortunately, we are trying to stop evolution, when any other species becomes an inconvenience to us it is controlled, destroyed, and then a charity is promptly formed to save it. The sick thing is though it is not just other species when something within society is inconvenient we take it upon ourselves to control it for the "greater good." Not only are we stopping evolution through natural selection, but we are destroying earths biodiversity. Problem being as biodiversity shrinks to fit a small window of tolerance the ability for the ecosystem as a whole to survive is dramatically weakened, so an unforeseen disaster now has the potential to not only wipe out an entire species but life in general. Read the book, it makes sense.
