The World Without Us

I just started reading The World Without Us by Alan Weisman. It's a fascinating look at how fast all of our infrastructures (buildings, roads, tunnels, ...) would collapse in a matter of years (not decades) if we were all to disappear from the surface of the planet tomorrow. Weisman was last night with Jon Stewart, very uplifting interview... for planet Earth. And oh, invest in bronze, it's apparently one of the most time-resisting alloys we have.
