From an energy conservation perspective nature is perfect. It is impossible for humans to do better than nature when it comes to conserving energy, which is a pretty key problem, so it seems a little optimistic to think that humans can do 1000X better than nature at very many things (or any?).
I don't understand. Energy is always conserved no matter if it's nature or humans - literally the first law of thermodynamics. Nature, humans, aliens, anything else is all "perfect" so I don't understand your point, or its relevance
I am suggesting that the assumption that humans are generally able to do 1000X better than nature may be flawed if nature can already do the most important things so well.
I don't doubt that you have well-intentioned beliefs, but before stating them again you need to withdraw and figure out how you can state them in an understandable way. When you've done that, come back and we can talk. I am saying this with the best of intentions btw.
