A native takes a picture with his mobile phone upon arrival of the indigenous groups at RioCentro for the handing over of the Kari-Oca II Declaration to leaders attending the UN Conference on Sustainable Development, Rio+20, in Rio de Janeiro, Brazil, on June 21, 2012. World leaders attending the UN summit in Rio weighed steps to root out poverty and protect the environment as thousands of activists held several protests to denounce Amazon rainforest deforestation, the plight of indigenous peoples and the "green economy" being advocated at the UN gathering.
