Material World by Ed ConwaySand, iron, salt, oil, copper and lithium: The struggle for these fundamental materials has created empires, razed civilizations, and fed our ingenuity and our greed for thousands of years. Though we are told we now live in a weightless world of information, we dug more stuff out of the earth in 2017 than in all of human history before 1950. And it's getting exponentially worse. Why? Because these ingredients are the basis for everything. They power our phones and electric cars, build our homes and offices, enable the printing of our books, and supply our packaging. Our world would not exist without them, and the battle to control them will shape our future.
