The question is whether or not you choose to disturb the world around you, or if you choose to let it go on as if you had never arrived. That is how one respects indigenous people. If you pay any attention at all you'll realize that you could never convert them to your way of life anyway. They are an intractable race. Any progress you advance to them will be undone before your back is turned. You might as well come down here to unbend the river. The point, then, is to observe the life they themselves have put in place and learn from it.
