03 May 2011, Bandung, Indonesia. Greenpeace activists together with PKK DAS Citarum (Citarum Community Activists) unfurled a giant banner with a "?" in the Citarum River to symbolize their demand to know what's poisoning their river, during the launch of the Greenpeace Toxic Free Water project entitled "Citarum Nadi Ku, Mari Rebut Kembali" (Let's Take Back Our Citarum). The Citarum is already one of Indonesia's most polluted rivers. Greenpeace called on the government of Indonesia to take immediate action to regulate industry along the Citarum at the launch of a public campaign to protect the river.
