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

LONDON, Oct 17 (Reuters) - The Earth's natural resources like food, water and forests are being depleted at an alarming speed, causing hunger, conflict, social unrest and species extinction, experts at a climate and health conference in London warned on Monday.

Increased hunger due to food yield changes will lead to malnutrition; water scarcity will deteriorate hygiene; pollution will weaken immune systems; and displacement and social disorder due to conflicts over water and land will increase the spread of infectious diseases, they said.
