At this point doing something that you're unsure whether it will make things better or worse is literally a better option than just nothing. I mean really what's the worst thing that happens? The equivalent of an oil spill? Like that's ever stopped us from doing things for profit? Why should we hold ourselves to these "better be entirely certain" standards when we never held ourselves to that standard on the way here?
This is a legitimate train of thought. "This might hurt things but I'm not sure how" simply isn't good enough. Give me a reason to be afraid to use this. Cause we're not afraid of using oil yet. Fuck it let's put a bunch of iron in the oceans. Really can't hurt things any worse than we have, can it?
