The United Nations Conference on Sustainable Development in Brazil has ended with participants approving a strategy on fighting poverty and environmental woes.
In a 53-page statement issued on Friday in Rio de Janeiro, 191 UN members voiced concerns at entrenched poverty and ecological degradation.
The document, titled "Sustainable Development Goals," called for replacing the UN's Millennium Development Goals from 2015.
The statement expressed dismay that over a billion people live in extreme poverty in the world, and presented a plan for a cure.
It categorized global warming as "one of the greatest challenges of our time."
"We are deeply concerned that all countries, particularly developing countries, are vulnerable to the adverse impacts of climate change," the text stated.
In addition, it mentioned a range of dangers facing the planet whose population is set to increase from 7 billion to 9.5 billion by 2050. The perils include desertification, fisheries depletion, pollution and deforestation.
"We... renew our commitment to sustainable development, and to ensure the promotion of an economically, socially and environmentally sustainable future for our planet and for present and future generations," it said.
The three-day UN event, commonly called Rio+20 or Rio Earth Summit 2012, was held in Rio June 20-22.
