WORLD HISTORY

Detailed explanation-1: -The regular flooding along the Tigris and the Euphrates made the land around them especially fertile and ideal for growing crops for food. That made it a prime spot for the Neolithic Revolution, also called the Agricultural Revolution, that began to take place almost 12, 000 years ago.

Detailed explanation-2: -Mesopotamian civilizations formed on the banks of the Tigris and Euphrates rivers in what is today Iraq and Kuwait. Early civilizations began to form around the time of the Neolithic Revolution-12000 BCE.

Detailed explanation-3: -The Tigris and Euphrates Rivers provided water for the irrigation of crops and for transportation. These two factors were conducive to the development of civilization. This was also the case in the areas surrounding the Nile, Indus and Yangtze Rivers.

Detailed explanation-4: -Civilization was possible in Mesopotamia because of the flooding of the Tigris and Euphrates rivers. This left a fertile layer of soil for crops and provided food for early settlements.

Detailed explanation-5: -The Tigris and Euphrates river system faces many challenges, such as decreasing water quality and quantity. Low water productivity, climate change and dam building are threatening the river system and leading to permanent damage to nature, urban migration and sometimes violent conflict in Iraq.

Detailed explanation-6: -With the development of irrigation, people turned from being controlled by the environment to being able to change their environment. As a result, communities began to push further and further south along the Tigris and Euphrates Rivers until, between 3500 and 3000 BCE, true cities emerged.
