But we have much about which to be humble. It's always the sort of thing where - if we can do it and it causes less harm ( and we're dead certain that this is true ), then do it. The shock from "All Cared..." is - what stability? Which equilibrium? If we choose them, how do we defend our choices? Obviously, nobody was doing this 70,000 years ago ( at least presumably not consciously ) and here we are, so... To a single-digit approximation, all species are extinct. Is it hubris to think we're smart enough to keep from destroying ourselves, or that we're powerful enough to destroy ourselves? Suppose we add Pigou carbon taxes. Does that mean poor people suffer more? So can we exempt them? Then isn't that sort of ... Empire-ey, the sort of thing a 19th Century Brit like Rudyard Kipling wrote about? I find the various anthropic principles to be of good use for this sort of thing.
