However, environmental information such as green-house gas emissions is not as easily accessible. A shift towards more plant-based diets could generate substantial public health gains. The human body is more efficient in transforming these food sources into calories and nutrients, adding to their overall health benefits. [24]
The large environmental impact of agriculture – such as its greenhouse gas emissions, soil degradation, deforestation and pollinator decline effects – make the food system a critical set of processes that need to be addressed for climate change mitigation and a stable healthy environment. A sustainable food system is a type of food system ...
