The author, a journalist whose previous books have addressed global warming, limiting family size, television content, and other ecological and energy issues, takes on recent and pending technologies which he suggests may change what it means to be human: cloning, advanced robotics, and nanotechnology. Examining the developments of the past few decades without getting either too technical or philosophical, McKibben asks whether it is not time for us to say "enough" -- to declare that just because we could do something, that does not mean we must. Although he doesn't present a rock hard case, he certainly poses the questions we all should be asking ourselves.
