What resources did Sumer lack in?

Answer 1

Sumer, despite its advancements, lacked several crucial resources, particularly natural materials like timber and stone. The region's arid environment also limited access to freshwater sources, relying heavily on the Tigris and Euphrates rivers for irrigation. Additionally, Sumer had limited mineral resources, which necessitated trade with neighboring regions for metals and other essential goods. This scarcity of resources influenced Sumerian society, prompting the development of extensive trade networks.
