Copenhagen and 'Taking Care of the World'

Yesterday, as a part of my university’s community outreach efforts, I delivered a lecture at a suburban retirement home on the theme of sustainable cities. I discussed Smart Growth, New Urbanism and the need for greater urban densities, all framed by the current events unfolding in Copenhagen at the United Nations Climate Change Conference.   At the end of my talk, several elderly ladies came up to chat with me and thank me for the lecture. On her way out, one turned to me and said, “You take care of the world for us. We’re not going to be around much longer – it’s up to you young people.”
