There are not many truly unknown places left on Earth, places where nobody knows who and what lives there, where the waterways go, or how the ecosystems operate. Eastern Angola is one of those places, and that helps explain why this place, which has little to no potential for agriculture, oil, development, or resource extraction, now finds itself with a number of suitors aspiring to protect it. This huge chunk of land, slightly larger than the state of Tennessee—flat, sandy, littered with unmapped and uncrossable waterways that sometimes change locations, like staircases in Hogwarts—could be well on its way to becoming a national park.
