The United States relies on imports for dozens of commodities in everyday use.Often enough, that reliance is 100%. In this book I aim to provide awareness of the hidden geology and mineralogy behind common things, and to develop an appreciation for the global resource distribution that underpins our society. While concerns about oil import reliance are in the news every day, our needs for other minerals are comparable and are typically unknown even to technologically aware Americans.
I was going to take a break from going through the commodities list alphabetically to say something about oil, since the price surge due to worries about Libya and the wider region has tripled the visitor count to my oil pages to more than 1,600 visitors a day (up from a consistent average of about 600), but what I would have said has already been more succinctly written. It boils down to "use less," but the complete, good report can be read here.
