this is the clearest communication i've heard on this topic, with specific sources and analysis supporting it:

no one should be eating (agricultural) red meat. it's bad for you, its bad for the ecosystems that are displaced by meat production, and its increasingly bad for the earth as a whole

quoting the interdisciplinary report that the video opens with:
« we must rapidly reduce meat consumption if the world is going to avoid ever more catastrophic climate change and environmental decline. »

whatever your personal feeling on it is, i urge you to watch the video. the food industry, specifically the large conglomerates that own most food production in the US, have done everything they can to cultivate uncertainty about this.

@chr so much of this video revolves around analysis of how so-called "ultra-processed foods" are bad for you, without any broader systemic analysis tying negative health outcomes to poverty and disability. it's also full of fatphobia, e.g. medicalizing "obesity."
