In this chapter, Peak Coal, Peak Uranium, and copper extraction are explored as illustrations challenging long-held assumptions about the inevitable certainty of continued global economic expansion. This chapter makes it easy to understand why careful management of our natural resources will be necessary for our economic and environmental future.
