    Remember, 70% of the earth's surface is covered by water. Antarctica is another nearly-10%. That's 80% that isn't human-occupied. In order to get to 1%, we'd need 5% of what's left.

    Do you really think that, for example, 5% of Asia is actually covered with human-made structures? Let alone Africa and South America? How about Canada?

    •  Might mean land area . . .. (0+ / 0-)

      In the USA, a few years ago I saw that if all the man-made structures (roads, building, etc etc) would almost exactly cover Ohio.

      Leaving everything else "pristine" - OTOH, Ohio is quite big if you think about it . . .
