The popular crusade against meat is one of the more misguided. Meat provides far more nutritional value than any plant and the environmental impacts have been greatly exaggerated. See below:
Regarding carbon:
"removal of livestock in the US would only lead to a net GHG reduction of 2.6% in national emissions. Similarly, removing all dairy would lead to a reduction of just 0.7%. At the same time, both transitions would create domestic deficiencies in critically limiting nutrients [White & Hall 2017; Liebe et al. 2020], which is not unexpected given that Animal Sourced Foods are valuable sources of essential nutrition [see elsewhere].
and methane:
"As argued above, this is not wishful thinking as there is still ample potential for mitigation of biogenic methane in global food systems. Moreover, the global cattle population has not been increasing during the last decade, making its contribution to global warming debatable [Shahbandeh 2020]. It is, however, true that methane has nonetheless been suddenly increasing since 2007. Yet, this can be ascribed to a multitude of potential reasons, incl. geological and fossil fuel emissions, wetlands, rice farming, and landfills [Gramling 2016; Nisbet et al. 2016; Alvarez et al. 2018; Rasmussen 2018; Etiope & Schwietzke 2019; Malik 2021], or a decrease in hydroxyl radical levels, the main sink for atmospheric methane [Turner et al. 2017]
