The adoption of a Plant Based Treaty as a companion to the UNFCCC/Paris Agreement will put food systems at the heart of combating the climate crisis. The Treaty aims to halt the widespread degradation of critical ecosystems caused by animal agriculture, to promote a shift to more healthy, sustainable plant-based diets and to actively reverse damage done to planetary functions, ecosystem services and biodiversity.

The debate is, of course, intensely political.
Here is an academic study on the ‘balanced diet’ from a fortnight ago:
Efforts to lower global meat intake for environmental or other reasons beyond a critical threshold may hinder progress towards reducing undernutrition and the effects this has on both physical and cognitive outcomes, and thereby stifle economic development. This is particularly a concern for populations with increased needs and in regions where current meat intake levels are low, which is not only pertinent for the Global South but also of relevance in high-income countries. role of meat in the human diet: evolutionary aspects and nutritional value | Animal Frontiers | Oxford Academic
