"To cover this contingency, I would like to propose an analogue to Pascal's famous wager… If I'm right, we will save the world. If I'm wrong, people will still be better fed, better housed, and happier,thanks to our efforts. Will anything be lost if it turns out later that we can support a much larger population than seems possible today? Suppose we move to stabilize the size of the human population after the "time of famines" at two billion people, and we achieve that goal by 2150. Suppose that in 2151 someone invents a machine that will produce nutritious food or anything else man wants in limitless quantities out of nothing. Assume also that in 2151 mankind decides that the Earth is underpopulated with just two billion people. Men decide that they want more company. Fortunately, people can be reproduced in vast quantities by unskilled labor who enjoy their work."

And this quote from an earlier chapter:

"What will be done with leisure time and money when all vacation spots are crowded beyond belief? Is it worth living in the Los Angeles smog for 50 weeks in order to spend two weeks in Yosemite Valley - when the Valley in the summer may be even more crowded than L.A. and twice as smoggy? What good is having the money for a fishing trip when fish are dead or poisonous because of pesticide pollution? Why own a fancy car in which to get asphyxiated in monster traffic jams?"

Live in Los Angeles, can confirm.
