Agriculture produces enormous amounts of animal waste, which in turn emits great quantities of methane, a greenhouse gas that contributes to global warming. But the dung beetle, which lives and feeds in feces, brings an unexpected breath of fresh air to decomposing cow dung. As the beetles tunnel through the dung they enable oxygen’s flow, limiting the production of harmful methane.
