What is the BEST way to explain the relationship between the fertile land of mesopatimia and the growth of the city of Uruk?

The fertile land of Mesopotamia, nourished by the Tigris and Euphrates rivers, provided the agricultural surplus necessary to support a large population, which in turn fueled the growth of cities like Uruk. The abundance of crops allowed for specialization of labor and the development of trade, fostering urbanization and complex societal structures. As a major center of trade and culture, Uruk became a hub for innovation, contributing to its prominence in ancient civilization. Thus, the fertility of the land directly enabled the rise and flourishing of Uruk as one of the world's first great cities.
