Preparing for climate change, averting a cold war with China, defeating terrorism: all of this requires geographic knowledge, argues Harm de Blij. Why Geography Matters, de Blij makes an urgent call to restore geography to America's educational curriculum. He shows how and why the U.S. has become the world's most geographically illiterate society of consequence--and demonstrates that this geographic illiteracy is a direct risk to America's national security. Peppering his writing with anecdotes from his own professional travels, de Blij provides an original argument that is as engaging as it is eye opening.
