> 1. Only something like 6% of the US is urban. The majority is pasture and forests, which arguably is almost entirely natural. The second largest use is crop land.
You have got to be joking, right? Just open Google Maps, switch to satellite mode, turn off labels and look at the US midwest, particularly Illinois. Any zoom level. Nebraska, Iowa, Wisconsin, Indiana, pretty much everywhere. It's a patchwork of farms. Basically all flat parts of the US look like this, except for extremely arid areas.
Combining pasture with range seems wrong, if "range" is open grazing land. That is wilderness, just with livestock on it keeping flammable undergrowth down.
