I’m having trouble understanding my lesson.. could someone me? it says i should now be able to explain the impact of westward expansion on native americans. i’m completely lost! (15 points )

It's asking how the westward expansion effected the native americans. A lot of it resulted in many native americans losing their homelands & being violently suppressed. They were forced out of the regions where they lived. A lot were killed from battles & diseases (diseases brought from the europeans). They wanted to keep their land that was being taken from them, hence the reason for the battles which resulted in many native americans lives being lost. 

Hope that helped a bit. 

Urban growth invariably feeds increased commercialization and industrialization. it requires continually expanding land areas. when urbanization rates are high, and countries do not have the institutional and managerial capacities or economic wherewithal to manage such rapid growths, they exert intense pressure on the types and nature of the resulting settlements. they contribute to the development of overcrowded slums and shanty towns without adequate essential services and necessary infrastructure.-by asit k. biswas and cecilia tortajada
