Heads of State and Global Leaders Gather at Rio+20

Heads of States and Governments gather for a family photo at the opening of the UN Conference on Sustainable Development, dubbed Rio+20. The summit comes twenty years after Rio hosted the UN's landmark 1992 Conference on Environment and Development and emphasizes global policies for poverty reduction, social equity and environmental protection. World leaders are gathered for the culminating segment in an effort to produce a comprehensive political document based on Sustainable development pillars.
