Steer 534: Why?

Pollan’s purpose for introducing steer 534 was to show a cow that was a product of artificial insemination. He showed the life of that cow since he was born and all the food it was eating. It showed the life of that cow with the mother but never meeting the father of that cow. He includes all of this information to teach us what is happening with these cows and animals and how they are living with their environment.
