1) Cattle wander around their still-smouldering pastureland in Rondonia, Brazil, one of the many huge tracts of the Amazon rainforest which are being torched to make way for agriculture. In the first five years of this century alone, Brazil burnt an area the size of England and Wales. Deforestation is responsible for 17% of human greenhouse gas emissions [GHGE], mainly through the burning of wood, which results in even fewer trees to absorb CO2
2)Chinstrap penguins perch on top of an eroded blue iceberg near Candlemas Island. Icebergs are simply fragments of glaciers, and last October an iceberg half the size of Greater London 'calved' from the vast Pine Island Glacier (Pig). Over the past 20 years, Pig has been thinning at 40 times the previous stable rate. Antarctica holds enough ice to raise global sea levels by 57m. The UN's Intergovernmental Panel on Climate Change has projected sea level rises by 2100 of between 20 and 80cm '
3)A girl carrying mangoes on her head descends to a village on the Olusosun landfill site in Nigeria. The Olusosun dump is Africa's largest, comprising 100 acres of garbage and collecting 2,400 metric tonnes of rubbish every day from Lagos, one of the fastest-growing cities in the world. Lagos's population has tripled in the past 15 years and the infrastructure can't cope. Roughly 1,000 homes have been built on Olusosun – the residents collect scrap from the dump and sell it
4)A kangaroo lies dead on Richard Walker's farm in New South Wales. In summer 2006/7 Australia experienced a 'one in a 1,000 year' drought. Rainfall in South Australia was the lowest since 1900, while temperatures in the country were the highest since the 1950s. Many regions were experiencing their fifth year of drought, and crops failed while livestock died. In Sydney, householders were fined A$220 (£100) if they were caught watering gardens, Perth's drinking water became saline
