river valley civilization
mesopotamia was the earliest river valley civilization, starting to form around 3500 bc. the civilization was created after regular trading started relationships between multiple cities and states around the tigris and euphrates rivers. mesopotamian cities became self-run civil governments. one of the cities within this civilization, ur, was the first literate society in history. eventually, they all joined together to irrigate the two rivers in order to make their dry land fertile for agricultural growth. the increase in successful farming in this civilization allowed population growth throughout the cities and states within mesopotamia.

the marshlands were an extensive natural wetlands ecosystem which developed over thousands of years in the tigris–euphrates basin and once covered 15–20,000 square kilometers. according to the united nations environmental program and the amar charitable foundation, between 84% and 90% of the marshes have been destroyed since the 1970s. in 1994, 60 percent of the wetlands were destroyed by hussein's regime – drained to permit military access and greater political control of the native marsh arabs. canals, dykes and dams were built routing the water of the tigris and euphrates rivers around the marshes, instead of allowing water to move slowly through the marshland. after part of the euphrates was dried up due to re-routing its water to the sea, a dam was built so water could not back up from the tigris and sustain the former marshland. some marshlands were burned and pipes buried underground helped to carry away water for quicker drying.
