The document discusses progress on Millennium Development Goal 7 of ensuring environmental sustainability. It outlines targets to integrate sustainable development principles, reduce biodiversity loss and the proportion of people without access to safe drinking water and basic sanitation, and improve the lives of 100 million slum dwellers. While some regions and habitats still face challenges, overall the world has met or is making progress on these targets, with over 2 billion gaining access to clean water and the urban slum population declining since 2000.
