"The issue is how we define the good life. Are the unlimited acquisition of material possessions and ever-higher use of energy the ultimate definition of the good life? How is this going to be sustainable on a global basis?
I don't think the answers will come easily. They certainly will not come wihtin the term of any one president. This is a debate that has to start within the country that, in a sense, has set the worldwide standard for material attainments and which, in the current global era, has to ask itself whether that standard is compatible, literally, with continued global survival."
