The logic I see thrown around here often "Technology got us into this mess therefore technology cannot help mitigate the mess" is not sound.
It's like saying Joe talked his way into trouble, he can't talk his way out. If Joe is a good talker & becomes more mindful of how others perceive his words, he probably can. Just as we need to become more mindful about the way we use technology. In the past we mostly only focused on it's short term effects & benefits, that's not going to be good enough henceforth but it's no reason to become a Luddite. Humans can desertify, with permaculture (a philosophy & collection of sustainable practices cataloged from around the world, which most people have heard about thru the Internet) humans can restore desert areas somewhat.
Money can get you into a mess, money may or may not be able to get you out. Being some freakishly strong muscleman may get you into a mess (some jealous guys want to beat you up) but it may also be able to get you out (you beat them up instead). I could go on & on.
This is not the thread to debate whether technology will "save us" and I'm certainly not saying that all technology is good or that technological change is more important than social change (I don't agree). Just correcting a logical fallacy I see thrown around here often.
As I've said dozens of times before, we can no more switch off our innovative natures than we can deevolve into squirrels. So rather than try (in vain) to disown that part of ourselves that wants to improve things (often with our plans backfiring) we should seek to master it as use it for good rather than either evilly or more often simply carelessly.
