This is a very interesting and informative podcast, and in many ways a joy to listen to. However, the question that haunts me when I hear how we as humans are joyfully looking forward to leave this world behind, and might maybe just miss Dunkin' Doughnuts and the like, is this: Am I the only person left in the world who feels that the uniqueness of the earth, with its unbelievable variety of life forms and overwhelmingly complex systems, much of which we have hardly begun to understand, is not just a piece of rock best left behind as soon as possible, but is intricately part of the very fabric of our beings as a species? Just asking.
