Why do we eat leaves from plants that grow on the ground, but not from trees?
Help me give my three-year-old authoritative answers to his difficult questions. He wanted to know why we don't eat leaves off the trees. And I have no idea! Other animals eat tree leaves, and people eat all kinds of green leaves from lettuces, cabbages, herbs, etc. Are tree leaves non-nutritive for humans? Would they make us sick? Or do they just taste bad? Please help me be Dad Who Knows Everything.
