Soaring international production of livestock could release enough carbon into the atmosphere by 2050 to single-handedly exceed ’safe’ levels of climate change, says a study. Scientists combined figures for livestock production in 2000 with Food and Agriculture Organization projections for population growth and meat consumption by 2050. They found that the livestock sector’s emissions alone could send temperatures above the 2 degrees Celsius rise commonly said to be the threshold above which climate change could be destabilising.
