That's not really a fair comparison.

  Isn't it? When the US surveyed (PLSS) its lands for the express purpose of selling it to citizens and immigrants, they didn't even bother to survey most wetlands, because they were thought to be entirely worthless and of no value. Certainly not anything worth saving or preserving. It sounds a lot like the attitude people currently have for the existing environment on Mars.
