Why Can't You Digest Grass?

The video explains why cows can digest grass while humans cannot. Cows have a specialized digestive system with a four-chambered stomach and microbes that break down cellulose in grass. Humans lack these microbes and the necessary enzymes. The video explores potential solutions for human cellulose digestion, such as introducing microbes or enzymes, but highlights challenges like acidity and nutrient absorption.
