RIO DE JANEIRO — The UN Conference on Sustainable Development opened Wednesday, launching a new round of debate on the future of the planet, its resources and people, 20 years after the first Earth Summit.
Opening the so-called Rio+20 Summit, Dilma Rousseff, president of host nation Brazil, called on “all countries of the world to commit” to reaching an accord that addresses serious environmental and social woes.
The UN conference, which marks the 20th anniversary of the Earth Summit that declared the environment a priority, is the largest ever organized, with 50,000 delegates, the United Nations said.
