I should acknowledge it was more of a caveat than a correction to be honest. Concentrated livestock farming has on the face of things significant efficiency advantages which can make compelling points, yet the infrastructure and resources to maintain more intense systems is easily ignored.

Taste can often be regarded as ephemeral, while fast fattened livestock can be discerned to taste different and are considered inferior in most food celebrating cultures.

There is a possible health factor involved with grass fed (or mixed prairie for better) beef and dairy accumulating a markedly different spectrum of omega oils, which are debated inconclusively, but also formally studied and theorized to be superior for human consumption.

A focus on the strength of methane emissions seems increasingly common in discussions and magazine articles, while the long developed advice from the IPCC is that CO2 demands priority because methane clears naturally in a decade or so, and requires less action to avoid than CO2 output which takes much longer to clear.

My understanding of IPCCs focus on CO2, is that while methane reduction presents an opportunity to buy a few years time, the priority is to convince action on the hardest problem which has been created, is worsening rapidly and much harder to clear.
