I’m watching a re-broadcast of Dr. Daniel Kammen’s six-part series on cable’s Science Channel titled Ecopolis. Here’s how it’s described: “A blueprint for city life in the year 2050, Ecopolis can benefit from new ‘green’ technologies being explored today that will lead to a more sustainable urban experience tomorrow.” Wow, I’m thankful for a Nobel Prize winning geek with a bent for communication and activism and a group of science video programmers who produce for cable TV broadcasting such positive visions of real possibilities for sustaining ourselves in cities of the future.
