They grace the crowns of royalty, sharpen weapons of war, and both power and pollute our cities.

They are Earth’s natural resources: treasures in the forms of stunning gems that we hold dear, metals that have altered the course of civilizations, and fuels that drive our modern world. NOVA's Treasures of Earth takes us on a journey deep inside Earth to uncover the mysteries of how these treasures were created, and to explore how they have allowed humankind to progress and build our great civilizations. But even as that quest continues... we are discovering that some of our treasures may soon run out or have unintended consequences that bring new perils. Can our ancient treasures reveal new secrets that will help us solve the problems we face today? NOVA Treasures of Earth: Metals airs Wednesday, July 18 at 10 p.m. on WXXI-TV.
