10/10/10 saw events in 188 countries joining together to raise awareness about climate change. See more here about 350.org. In Stroud there was a gathering near Nailsworth at the weekend at the Thistledown centre - in 2009 there were several events.
In relation to this blog in Loja, Ecuador, students from the local school got together to clean up the paths around their school and town, and to harvest the potatoes in their school's organic garden. See here and see photo of the 350 made out of potatoes. Meanwhile here there is a blog on how to do potato cuts to get across the 350 message.
