This is definitely a must read for anyone laboring under the illusion that our planetary resources are unlimited. A lot of people may be disturbed by the well corroborated fact that in 40 or so years the earth's supply of oil will be entirely depleted and that shiny Escalade will be a worthless pile of metal. Yes, we believe that we are so rich in this country, but the truth of the matter is that we're poor beyond our imaginings, to borrow a quote from the book.The book does differ from others I've read in that it does offer hope for mankind's future existence, provided we welcome change both as a nation and as a species.-Dennis from Vallejo, CA
