Fifteen Greenpeace activists unfurled a 50m x 30m banner from the Rio-Niterói Bridge with the message: “World Leaders: Climate and People First!” after rappelling the bridge at the Guanabara bay in Rio de Janeiro. Greenpeace sends a clear message to the leaders of the 20 richest nations in the world (G20) who will be gathering in London tomorrow to discuss the global economic crisis.
