I especially appreciated the author's focus on the economics of junk and refuse, which is the main factor as to whether stuff has a chance at a second (or third!) go-round, or if it just gets buried in a landfill. Since reading the book I've become more aware of the valuable materials all around us that seem to be just useless junk -- such as the copper wire and steel in the electric fan that won't run, the strings of Christmas lights that won't work (more copper! Plastic for flip-flops!), and the hundreds of "dead" farm implements and old pickups rusting behind barns around here (steel for new tractors!). An interesting book if, like me, you have a fascination for junkyards, or if you are concerned about our environment.
