Two notable societies that attempted to change their environment are the ancient Mesopotamians and the Inca civilization. The Mesopotamians developed extensive irrigation systems to manage the Tigris and Euphrates rivers, enhancing agriculture in an otherwise arid region.

Both societies exemplified significant engineering and agricultural innovations to adapt to and transform their environments.
