The bumpy road to Rio+20

The international community is stumbling in its efforts to find a middle path to a greener planet. Less than a year remains, when nations will converge in Rio de Janeiro to renew their vow towards sustainable development and a greener economy. The UN World Summit on Sustainable Development, popularly known as Rio+20, will not only review achievements and failures since the Earth Summit of 1992 held in this same city but will also need to provide a road-map for sustainable development. But a recent round of negotiations in New York in May 2011 was nothing but a squabble.
