I don't. The reason is that even though we are probably capable of doing so we lack the responsibility required to do this without the chance of massive negative side effects. Every time we've upped the scale in our abilities it has only resulted in more damage, not quite balanced out by more progress. This is a real problem: we can get ourselves into the kind of trouble that we don't seem to be able to get ourselves out of. We never stop and say 'this is enough', we always take the next step, create a new level of problems that then requires yet another level of innovation to control it and so on.

It's the sorcerers apprentice, but a weird variation on it. Just supposed that what the GP says is possible and doable: what guarantees do we have that we fully understand the system we are messing with? How much risk are we willing to take? Who are the stakeholders in these risks?

Without answers to all of these questions we run the real risk of biting off more than we can collectively chew and if and when we do there won't be an 'undo' button to press. Well, technically will have pressed it, but quite possible on a time-scale that we didn't quite envision.

I've seen the most stupid proposals of the kind that you are suggesting: PNE's ('Peaceful Nuclear Explosions') on a scale never dreamed of before to remake the face of the Earth, create new watersheds and so on. And to incidentally put an amount of radiation into the atmosphere that would be absolutely unparalleled. The fact that we can do these things doesn't mean that we automatically have to do these things.

I keep thinking about the discovery of nuclear power: what if we hadn't? Would that be such a huge problem or would we simply have found other, better ways of providing ourselves with power? And if we did, what would be the short term, mid term and long term consequences of doing so? Because the energy stored in the core of the Earth is the ultimate form of fossil energy: between gravity and plate tectonics life had a way of escaping the oceans and without that we'd be fish, mammals in the ocean at best. Good luck with that electronics project you were working on in that environment.

It's tricky: we have one Earth. Any decision that irrevocably removes something from that Earth carries a price tag the value of which may not be visible for a long time to come, so caution would seem to be the best way forward, even if that isn't our nature. Our nature is just to act and then to pass the buck to the next generation.
