Urbanization's Green Outgrowth

Clip Excerpt: Recycling didn't have a government program or environmental study behind it when I was a kid in Bogota in the 1970s, it just happened. Every week, a wooden cart would appear in the street and we'd hear the cry -- botellas, frascos, papel! My mom would rush out with whatever bottles, jars and newspapers she had saved and exchange them for a few pesos with those Bogotanos who eked out an existence in repurposed trash.
