Bristol's Big Green Week

Aside from the fact that its organisers clearly have no idea how many days there are in a week (!), this looks like an entirely admirable event. Imagine, if you will, 9 days of environment ideas, art and culture - at the very least it's an appealing antidote to the hand-wringing and doom-mongering that surrounds Rio+20. Bristol's Big Green Week is the UK's first ever international festival devoted to inspiring and empowering people to act on sustainability. Its action packed programme includes lectures, markets, parties, playgrounds, performances, debates, films, acts of worship, workshops and interactive exhibits - something for everyone, in fact. It even has a fringe.

Just one word of caution - there's so much going on that if you print the entire 7.5MB, 25 page pdf file of the programme you'll consume the equivalent of a reasonably-sized seedling, so save it or download the handy app. Go, enjoy and be the change you want to see!
