London Green Fair 2012

Celebrating its twentieth anniversary, London's largest green festival returns to Regent's park with stands and stalls by campaigning organisations and representatives from Friends of the Earth and others, organic and Fairtrade food and fashion for sale, workshops, talks and performances divided into eco-zones. There's world music on the Global-Local stage, plus an 80-piece orchestra from Holland, a speakers and conference area, and a kids zone offering dance classes, music lessons, storytelling and performance. The fair also includes BikeFest, which gives the opportunity to try out the latest electric bikes.
