It's difficult to conceptualize global warming. A lot of people probably picture it as a thermometer differing a few degrees. So we'll wear coats less often in the winter, what's the big deal?
Of course, the reality of the situation is that that humanity survives entirely because of the productivity of various ecosystems. These ecosystems are facing severe disruption. And these disruptions work their way all the way up the food chain to us.
Don't worry, hydroponics, artificial meat, or Geoge Jetson's food pill will save us. The other animals are just useless eaters (see also poor people) who are just using up useful oxygen and putting out carbon dioxide. We don't need no stinkin' badges, or ecology. We were promised a free pony who shits a rainbow of Skittles ... so much for Earth Day 1970 (I was there).
I will, in any technical post, be harsh on, any "free lunch" or "techno-fantasy". You can do wonderful things, but only if on a small scale, and only if you can afford it. But for now, we don't pay the true price for anything, in the First World. And extending First World conditions to the whole human race, is ... a numbers problem. You can have any techno-fantasy you want, as long as you have unlimited free resources ... and no ecological footprint ... aka US before Earth Day 1970.
