What economic and social problems are faced by citizens
Nutrient-rich soil for farming
If you remember, a lot of Okies went to California during the Depression because they had "ruined" the land to the point they couldn't use it anymore
The land was rugged containing Andes mountains, the coastline deserts, and the Amazon jungle. They eventually found solutions for their geographic problems. I hope this helps :)
The Columbian Exchange had positive and negative consequences.
Some of the positive consequences were the introduction of different nutrients and food supplies into the Old World, such as corn or potatoes. This improved the diet of most Europeans, leading to a population growth in the next generations.
However, Europe benefited more than the Americas, for some of the negative consequences about the Columbian Exchange were the introduction of diseases into the continent and the slavery of African populations into the Americas.
