I never stated that there were painless or negative side effect free power sources, you are the one who stated it was the most painless way forward. The additional power sources you are advocating are nuclear. I said nothing about eating animals. The whole universe isn't trying to do anything. When the power sources you speak of are consumed by your ideal life form, is it going to consume itself? Have you ever heard that energy is neither created nor destroyed, it just changes form? Contributing to as animals do, against directly causing like you advocate your ideal form doing, are different notions.
