There are too many cows. There need to be fewer cows. The number of cows is too damn high. The level of cow must decrease. The cow line go up but must go down. There is a supercritical mass of cow. Only falling cow numbers is compatible with a livable future (and present.) There is an excess of cows. There needs to be a correction in the number of cows. We must bend the cow curve downwards. There must be a decumulation of cows, a de-escalation, a degrowth of cows.
(Obvoiously i don't care about anglers arguing for their share of the exploitation but the health of Aotearoa's waterways is vital for a robust ecosystem.)
