I would also advise writing to your local MP (find them here http://www.theyworkforyou.com/). It's easier to ignore 4,000 digital signatures than 4,000 physical letters. It wouldn't hurt to call them either.
I find myself thinking "I don't want to live on this planet anymore" more and more often these days. Not sure if I'm just getting older, or the world really is going to shit.
