Most amusing in the extreme.
Last week cow farts were a menace to the planet due to methane which has a short half life of just a few years and we are now at stable state and methane due to cow farts is no greater today than 50 years ago.
But alas cows can apparently digest plastic and become a great boon to the environment and thus Gaia is saved.
This Texan has never seen a cow eat a plastic bottle.
They certainly enjoy eating their own afterbirth (slurp sluuurrp). First time I saw that I was probably age 5. My sis (3 yrs older) still remembers me standing there, eyes and mouth wide open. I remember my sons first times and reactions. Lol
