Nowhere did I say humans are a foreign entity. I said our existence does harm to ecosystems all over the globe. That is a fact. We also, uniquely, have the ability to choose* whether or not we do that harm, which oxygenating bacteria did not. So here I am, advising someone to do less harm because doing harm causes them pain, and you're saying... what? That choosing to counteract the harm we've done is foolish and illogical? That makes no sense.
