Lines upon learning that scientists have recently isolated methane-mitigating microbes in the intestinal lining of the kangaroo, and plan to replicate them in cattle to reduce the emission of “cow-created” greenhouse gas

The cow, our windy sister, sends up fumes
that linger in the rafters of the world.
Low-flying angels get their eyebrows curled!
(She does not mean to do this, one assumes.)

I’ll imitate the noble kangaroo
who — though he shares her dietary whims —
is fart-free, back-sprung, bouncing on his rims;
not gassing off, like cows and humans do.
