Rearranging Our Pieces, Playing With Our Future

Is our imagination so limited that we think anyone will survive by doing the exact same thing we've done for half a century? Why can't we take the same simple wonder of an afternoon of play and build a new world with the pieces we already have? Why can we not take our bricks and track and blocks and rearrange them, as we did countless times as children, into new buildings, new cities and new transportation networks? Why can't we put our architects to work redesigning the decrepit spaces that already pepper our world? Why can't we put builders to work reconstructing our destroyed communities? Why must we mine new materials and continue the urbanization of our wild lands when so much unused housing stock and other structures sit vacant?

Why can't we rearrange the pieces we already have? If we could do it endlessly as kids, we really can do it now.
