Sheep provide food, commerce, and health to the city that works them.
For centuries, sheep have had associations with many Mediterranean cultures. Many religions, such as Judaism and Christianity, use sheep-related images and parables. Raising sheep provided a steady source of income to ancient farmers since the animal can give milk, wool, and meat. Even in the 21st century, sheep can provide a return on investment of up to 400% of their annual cost (including reproduction gains).
