Hey, Huntard
Would you care to mention any? Cause I can't think of (good) ones.
One reason in support of a meatless diet is the ability to feed a greater proportion of the human population. (Meatless) Vegetarians are primary consumers, consuming a plant-based diet. Eating corn-fed beef, for example, lifts us to secondary consumers; the cattle eat the plants, mostly corn, and we, in turn, eat the cattle.
In so doing, we lose ~90% of the energy available to us in the lower trophic level, as primary consumers.
