The largest environmental event in Philadelphia for the past couple of years has been GreenFest Philly. It’s a street fair that takes place in September in Headhouse Square, the cobblestone streeted area where Second Street meets the always hip South Street.

I went to this event last year and had a great day. I had the opportunity to sample some food, take a look at some green products, trade in some old clothes at the clothing swap and come home with some new-to-me items, and talk with lots of people in the region who are working toward a better environment.

This year’s GreenFest Philly theme is sustainable food, so you know I’m going to be there again. In addition to the 200 plus vendors who will be at the festival, there will be a food symposium with various speakers educating festivalgoers on organics, vegetarian/vegan options, and animal products and the environment.

Music, a green film festival (ending with a showing of Food, Inc.), and kids' activities round out this day of environmental fun.

This year’s sustainable food-themed GreenFest Philly will be held on Sunday, Sept. 13 from 11 a.m. to 6 p.m. at Second and South streets.
