Construction schemes in the modern style need enormous quantities of aggregate to keep the production of concrete going and any 'expansive' government isn't going to want to slow that stream down. The 'burning' of the clay and limestone to make Portland Cement has been described as producing 3% of the annual carbon dioxide global emissions. (And about a half of all cement is wasted, in my experience.) The buildings that are being made of this stuff - steel frame and cinder block - are very poor and have an absolute lifespan of maybe thirty or forty years. To stop them being built would take an entire revolution of thought - 'no more crap' - and is probably practically unfeasible.

There's a meteor shower at the weekend with a good picture of Orion's Belt just here http://skyandtelescope.com/observing/objects/meteors/article_802_1.asp
