This is a funny, goofy book with (I think) a couple of subtle yet important messages. The first, and most obvious, message is that human beings have wreaked such havoc and destruction over the planet that we are very close (if not past) the point of no return. The second message is that much of our lives are spent allowing things to happen to us because we are not willing to take a risk. Our intentions may be good and honorable, but we still end up trading our real selves for imagined security.
