Pledgebank says it can make collective action easier on a local and national level, by letting people publicise their personal campaigns. Pledges take the form of requests for help from like-minded individuals – for example "I will donate 1% of my salary to charity if 100 other people do too" – and can be signed up to using the internet or text message, and the site provides ready-built flyers and material to help gather support.
We are marching across America for one year, *via the internet*, to bring everyone together in one loud clear voice of concern to urge our leaders to address global warming now. Please join the march and make your voice heard too.
