37 per cent of all human-induced methane, which is largely produced by the digestive system of ruminants, and 64 per cent of ammonia, which contributes significantly to acid rain. Livestock now use 30 per cent of the earth’s entire land surface, the report says, mostly on permanent pasture but also including 33 per cent of the global arable land — used to produce feed for livestock, the report ...

need to investigate the possibility of catastrophic side effects. At plan B level, there are several options that might help to remove CO 2 from the atmosphere. The idea of fertilising the oceans with iron in order to produce algal blooms gets poor marks. The results of Lohafex, a recent fertilisation experiment in the South Atlantic (Curr. Biol. 19, R143), have also suggested that the carbon r...
