Animals are often used in picture books to illustrate human behaviour in a society. In Baaa, David Macaulay shows how sheep built up culture similar to humans, after humans.
Around this time, leaders arose from the sheep
population. Some had charisma, others connections.
One evening, between commercials, a news sheep
announced that things were being used up too fast.
But nobody paid much attention.
