How did the environment and technological innovations affect the expansion of agriculture, cities, and human population? What impact did human expansion have on the environment?
Humans developed cities and civilizations in areas where there are resources to enable people to survive; as humans began to live more around river and water areas, this allowed for an agricultural boom, leading to population growth as more people were able to be supported by the resources. As these waterways allowed humans to travel more, hunt different animals and trade, these small towns became cities, housing hundreds, and thousands of people. The need to organize as a society and community led to the commodification and control of these natural resources and trade routes, which led to more innovation, and subsequently human pollution from those innovations which have and are continuing to impact the environment and human health.
