Gotthold Ephraim Lessing

Sometimes you see films, not just science fiction films, where you get the sense that if the camera were to pan just to the left or the right, all of a sudden you'd be seeing light stands and crew standing around. But with 'Blade Runner,' the beauty of it is that it felt like a real, breathing city.

We need the humbleness and clarity to see that our food, while benefitting from technological advances, has benefitted even more from free ecological resources: Cheap energy, lots of water everywhere, and a stable climate.
