"We are often told we are materialistic. It seems to me, we are not materialistic enough. We have a disrespect for materials. We use it quickly and carelessly. If were genuinely materialistic people, we would understand where materials come from and where they go to. But, at the moment, the entire global economy seems to be built on the model of digging things up from one hole in the ground on one side of the earth, transporting them around the world, using them for a few days, and sticking them in a hole in the ground on the other side of the world."
