20、f that were an examination topic, most students would tear it apart, offering a long list of complaints: from local smog to global climate change, from the felling of forests to the extinction of species.

It is where prices and markets do not operate properly that this benign trend begins to stumble, and the genuine problems arise. Markets cannot
