EarthView helps us to understand that humans rely on a very thin layer of resources very close to the Earth's surface. For example, the deepest mines in the world would be only about 2 mm deep at EarthView scale. The Physics Factbook offers a good explanation of how heat and pressure combine to limit the depth of mining.
Even at its very thickest, by the way, the Earth's crust would only be about 17 mm thick at EarthView scale.
