What things are made Of : America's Global Dependency on Just about Everything

The United States relies on imports for dozens of commodities in everyday use. Often enough, that reliance is 100%. This book provides awareness of the hidden geology and mineralogy behind common things, and develops 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.
