Avaaz - which means voice" in various languages - has become a global pressure group to be reckoned with. It's a new kind of activism that isn't issue-led, it's issues-led. It's human rights abuses in Burma, or it's the Syrian civil war, or it's threats against the Great Barrier Reef or it's homophobia in Costa Rica. It's whatever its supporters, guided by the Avaaz team, choose to click on most this month. If it launches a campaign, it throws its resources at it - and a chunk of its $12m budget a year, all donated from individuals - and there's a fair chance it will have an impact. Avaaz is both global and globalised and its approach is less bleeding-heart liberal than hard-headed pragmatist. Its growth is exponential: they've gone from nine employees in year one to 100 now. In September, I interviewed its softly spoken Canadian founder, Ricken Patel, and noted in the transcript that [Avaaz] now had 26 million [members]. By the time this piece appears in print in November, that number will be hovering around the 30 million mark. "Liking" a Facebook page isn't going to save the world. But five times as many people in Britain are members of Avaaz than they are of the Labour Party. And 30,000 people donate money to it every month. To save the world, click here.
