I want to know the answer to the following question:
Why did agricultural societies push into hunter-gatherer areas?
All the background I'm provided with is that "This process of agriculture-driven expansion led to the development of the first forms of government in agricultural centers, such as the Fertile Crescent, Ancient India, Ancient China, Olmec, Sub-Saharan Africa and Norte Chico.". Is that enough to answer the question?
Answer: no
