If you're tying ribbons to trees in forests but not to other trees, you (or other interested folks) can correct any errors. And, if you actually wanted to be fair, you'd fix your mistakes yourself (or with your own resources) instead of expecting everyone else to clean up after you. If you have robots chopping down forests, there's not much to do when they're wrong except apologize and explain that algorithms are hard.
