More than 14 million people from around the world already joined AVAAZ.ORG. It is by far the largest ever online petition in the history on mankind.
From their about us page:
Avaaz.org is a new global web movement with a simple democratic mission: to close the gap between the world we have, and the world most people everywhere want.
Across the world, most people want stronger protections for the environment, greater respect for human rights, and concerted efforts to end poverty, corruption and war. Yet globalization faces a huge democratic deficit as international decisions are shaped by political elites and unaccountable corporations — not the views and values of the world’s people.
