TEXT: Global powers convene1 at the Rio +20 U.N. conference to try to determine a sustainable pathway for global development. A draft text prepared by diplomats2 this week laid out global aspirations3, rather than mandatory4 goals, on issues like food security, water and energy. The U.N. announced that more than 50 governments have launched new energy strategies while private investors5 have pledged more than $50 billion to global renewable energy initiatives. Greenpeace activists6 raised a huge polar bear balloon next to Rio's iconic Christ the Redeemer statue, calling for a U.N. resolution that would establish a global sanctuary7 in the Arctic, banning oil drilling and unsustainable fishing. Meanwhile, Brazil and China signed a handful of trade agreements aimed at boosting investment and commerce flows for the coming decade. Sarah Sheffer, Reuters
