The Future We Want: Rio+20

World leaders approved the outcome document for Rio+20, entitled "The Future We Want," adopted by 193 members of the United Nations on June 22. The outcome of the Rio+20 summit provides further proof that the nation-state system is failing badly in tackling global environmental threats. The UN's Conference on Sustainable Development (RIO+20) had been billed as a once-in-a-generation chance to overhaul an economic model that had left a billion people in poverty and imperiled the biosphere.
