A woman called Michelle Farnham is now 17 days into a 3 week protest, living in a cage, at Trafalgar Square, to try and save a pig called Luna (who lives in an identical cage). She stays there day and night.
It has not had any big coverage, as far as I can see. I think it's a bit of a shame that violent and disruptive protest gets so much coverage, while quiet sort of self-sacrificing things like this, that do not harm anybody or any property, get less attention.
Whether you or I agree with her, or what she's trying to do, what an impressive commitment, eh?
