Australia's dung beetles are cutting cattle methane by 85%. The finding is bigger than the beetles.

A Southern Cross University field trial found introduced dung beetles slashed methane from Australian cattle pats by 85%. The result reframes a $50bn livestock export question, and asks why biological abatement got so little policy oxygen.

Desk note: Monexus framed this as a policy-arithmetic story, not a nature piece. The beetles are the hook; the gap between the 85% figure and the absence of a national rollout programme is the argument. Wire coverage to date has led on the biology; the climate-policy angle is underdeveloped and is where this article adds value.
