Ancient felling may explain carbon-sink forests

CAN we thank destruction caused by ancient civilisations for the fact that rainforests are soaking up carbon? An analysis of tree growth and death across tropical Africa has found that each hectare of forest soaks up about 0.6 tonnes of carbon a year (Nature, vol 457, p 1003). This result, reported by Simon Lewis at the University of Leeds in the UK, mirrors the carbon-absorbing ability of the Amazon rainforest. In theory,
