A bunch of people sent in links to Google's new "Summer of Green" mashup. The minisite features videoclip tours of environmentally sensitive spots in five cities, including the Big Apple. It's a cool idea, but there are only five clips available for New York City-- so if you're planning on using the map as a tour-guide, better plan for a short trip. If you want a real environmental guide map to NYC, check out the GreenMap.
