The next frontier will be meat consumption. Particularly red meat. A single 1/4 beef hamburger emits 7-12 kg of carbon[1]. Compared to ~1.5kg of carbon driving your car 3 miles[2]. Not telling you to go full vegetarian, but I'm personally far less interested in a beef product unless you're going to guarantee its an extremely expert prepared steak. Most beef is mediocre. 1 - https://ourworldindata.org/environmental-im…
Meat, and red meat, is truly a miracle food. Dense in nutrients, satiating and of course tasty. Nature needs animals as well. In fact it is essential. Agricultural reform or innovation is certainly an avenue to explore; but this strange obsession with "stop eating red meat" is a bit too much.
That most red meat is very co2 expensive compared to getting the proteins from other sources is a relevant argument for many of us, and not a particularly 'strange obsession' for those of us caring about reducing our co2 footprint.
