Question

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

Answer 1

We humans cannot survive only on raw, leafy vegetables or grass since the grass

or leafy vegetables are rich in cellulose. The cellulose is a type of carbohydrate

which cannot be digested by us since the cellulose – digesting enzymes are

absent.
