Explain how different types of societies have adapted to and affected their environment?

Through multiple revolutions, people have adapted to and affected their environments. As civilizations settled, new advances in agriculture and tools were made to allow for a less-nomadic society. Through advances such as iron tools and food stock, civilizations settled creating the basis for large empires to come later. Also through the innovation of weapons and armor, empires were able to better control and defend larger territory allowing for exponential expansion. Finally, with new advances made by different civilizations, trade increased as demand for new products from other empires grew.

Cities are liable to occasional depressions of trade, resulting from over production, or the successful rivalry of foreign nations, or even portions of the same country; or there are smashings of banks, and commercial panics, and periods of general mistrust.
