Photographer Peter Caton talks about his visit to the Cerrado – the world's largest savannah. It contains 5% of the world's biodiversity, but is being destroyed at an incredible rate to make way for monocultures that may have devastating long-term effects.

During his trip, Caton worked with local Brazilian environmental group ISPN and WWF on their campaign calling for UK supermarkets to source sustainable soya

Eleven years ago, at the Millennium Summit at United Nations headquarters in New York, the leaders of the world agreed to a plan meant to spur efforts to help the globe's poorest.

The proportion of the world’s population with access to improved drinking water sources grew by 10 percent over a period roughly covering the past two decades, according to a United Nations study released Tuesday.

The study was released by the United Nations Children’s Fund (UNICEF) and UN World Health Organization (WHO).

The study found that between 1990 and 2008, the proportion of the world’s population with access to improved drinking water sources increased from 77 per cent to 87 percent.

We are right on the equator, and Speke, Moebius, Elena, Savoia and Moore, the five great glaciers of the the Rwenzori, the Mountains of the Moon, glint in the bright Ugandan sun. Usually lost in the mists that cloak these peaks up to 5,100 metres high, the glaciers are the only major ones left of the 43 that were mapped and named in 1906. Then, the ice covered 7.5 square kilometres, now it is thought to cover less than one.
