That's what I am calling AOL's list of top ten green cities -- the top ten cancer prevention cities -- because when it comes to reducing environmental cancer risks and promoting a healthy lifestyle, a city that is known as a green city is also a cancer prevention city. AOL's criteria in choosing the top ten green cities they believe are creating a healthy and livable place for its residents are: clean air and clean water, renewable energy, reliable city buses, trams, streetcars and subways, a growing number of parks and greenbelts, and farmer’s markets.

Not to claim bragging rights, but my hometown of Portland, Oregon is on the list. Austin, Texas; Minneapolis, Minnesota; Boulder, Colorado; Burlington, Vermont; Madison, Wisconsin; San Francisco, California; Santa Monica, California; Chicago, Illinois and New York, New York made the list. New York City? Yes. According to AOL's reviewers, Central Park goes a long way in making New York City a green city. As does the fact that 80 percent of the residents use public transportation. New Yorkers use fossil fuels at the rate the U.S. did in the 1920s. To learn all the ways these cities made the green list, go read AOL's Top 10 Greenest Cities. Or as I like to think of it -- the top ten cities promoting a healthy lifestyle and maintaining clean livable areas resulting in the creation of a cancer prevention environment -- the top ten cancer prevention cities.
