Question

Can we survive only on raw, leafy vegetables/grass? Discuss.

✓

Answer

No, we cannot survive only on raw, leafy vegetables/grass. This is due to the absence of cellulose degrading/digesting enzymes. Raw, leafy vegetables and grasses, etc. contain cellulose, which is digested in ruminants by the action of microorganism, but humans do not possess these microorganisms. Therefore, we will not be able to digest cellulose and meet our energy requirements.
