Rio+20

The United Nations Conference on Sustainable Development, or Rio+20, begins today in Rio de Janeiro, Brazil. An outgrowth of the Earth Summit held in Rio in 1992, the conference is designed to bring together 50,000 delegates from state governments, institutions, and non-governmental organizations to create measures to reduce poverty while promoting clean energy, decent jobs, and sustainable use of resources. The conference has attracted many protests and parallel events, as diverse groups struggle to share the world stage and make their voices heard. Collected here are just a few of the scenes from Rio+20.
