The "perfect" ecosystem -which would be what exactly? Even you couldn't possible assume to know this (gives new meaning to hubris, if that's your claim).
It's very easy to identify a perfect ecosystem. It's an area (the larger the better) that has yet to have been changed by humanity.
So again, the implied solution to all planet earth's "problems" (completely manufactured bullshit repeated over and over to brainwash people to agree to be subjected to every form of tyranny imaginable) is extinction of the human race. Mhm...
