Can we enact change?

We were on the Piccadilly Line yesterday travelling back from our day in London and I saw this advert by Amnesty International.

It held my attention for 3 or 4 stops, it had an impact, it resonated deeply within me.

Is it true?
Can we change what happens in Oran by texting, emailing, signing, donating or blogging here?

It was weird to go through these thought processes, this is me. Emma. I blog for many reasons, one of which is trying to make the world a better place. Why do I do it if I don't believe it's possible?

And I realised that I do believe it's true, but it's so seldom you hear anyone else say it as well.

One text from your phone CAN stop a stoning in Iran. I just wish I'd read who to text and what to say.
