Change The World for a Fiver

Very accessible - read it in bite size chunks and let it sink in. Lots of ideas for how to positively change the world, founded very much on the ethos of lots of small changes building up to a big one.

For the armchair activist who wants a kick up the backside. I was already doing some of the ideas found inside, but I'm embarrassed to admit that I haven't done any of the new things since reading it.

Buy it for the poster that comes with it - stick it on the wall of your office and you've an instant talking point good for finding like-minded souls.
