Everything we see and touch is made from something, however, distantly, the Earth has given. And we take a great deal, seemingly without a second thought. We expect the shelves to be stocked and the tap to flow, without really acknowledging the systems that make it all possible. It saddens me sometimes to look around and see how we have reshaped the world to satiate our hunger. One could argue, of course, that as part of nature human settlements and influence is completely natural. And there is truth to that.
