Environmental factors to the development of the global economy.
Explanation:
The industrial revolution changed the global economy from 170 to 1900 as it went through different stages of industrialization. The steam engine made it possible to take advantage of resources from fossil fuels, especially coal.
The need for raw materials for factories led colonies to export in exchange for manufacturing goods.
After World War 2, resources depleted, and so did the economy. The war had used up a lot of them, because the war lasted longer than anyone predicted. So came the Great Depression.
