“Balanced diets featuring plant-based foods, such as coarse grains, legumes, fruits and vegetables, and animal-sourced food produced sustainably in low greenhouse gas emission systems, present major opportunities for adaptation to and limiting climate change,” Debra Roberts, co-chair of IPCC Working Group II, said in a press release. (In the summary of the report, the IPCC acknowledges that factors like financial barriers and cultural habits may influence the adoption of such diets.)
