I agree with putting gardens atop all the tall, flat-roofed buildings.
At the same time, i think we should apply a coat of white "paint"--mebbe some kind of insulating material--to every PITCHED roof in the country, and on every parking lot, every street, and any other otherwise unused horizontal surface of human manufacture to reflect light/heat and surrogate for the disappearing ice on the poles.
I also think the State (state/fed, machts nichts) should underwrite the process of installing some kind of photo-thermal or photo-voltaic collector on all that roof-space, too. This will spawn new industries in the manufacture and installation of such devices, which would offset the losses in employment in the traditional energy fields. EVERY responsible economist agrees with this assessment. Plus, making individuals CONTRIBUTORS to the community energy pool, and not just consumers from it, will i think be crucial to any even remotely successful efforts to garner BEEG public support for the changes that are coming. It is NOT inappropriate that the "state" should underwrite much of this expense, since it is no less than the commonweal which is at stake...
In any kind of disinterested calculus (the inter-planetary ethnologist, e.g.), humanity does not have the right to exterminate any and all but its own, domesticated animals in the exploitation of the planet's energy resources, but that is almost certain to happen unless there are specific infrastructural prohibitions against it. So the preservation of bio-diversity must be non-negotiable, for either moral or practical reasons, whichEVER is most persuasive.
Ps: I took down the "Lila" post. My girl objected that it (that i'd) violated her privacy, and she's right (tho not, too, sorta). Any objective observer would have recognized that the post was an act of major self-pity, as much as anything, which is embarrassing, in flagrante delicto...
still, thank you for your replies, your consolations.
