-Turkey and Llama are probably the only prominent New World domesticated animals which were introduced to the Old World. However many animals were imported to the New World including horses, cows, chickens, donkeys and pigs.

-These animals, especially pigs because they breed very quickly, expanded the food supply in the Americas. Abundance of food was the primary reason behind Europeans coming to the Americas in large numbers.

-A disease called Potato Blight destroyed potato crops throughout Europe in the 1840s it led to the Great Famine in which Ireland’s population fell by more than twenty percent. The Irish Potato Famine was responsible for the death of about 1 million people and a million more emigrated from Ireland.

-Cassava provides more calories than any plant on earth and is the basic diet of more than half a billion people in the developing world. Sweet potato, which is also a New World crop, is poor people’s staple in China.

-Columbian Exchange led to commodity crops, goods etc. being produced in the Americas to be sold in Europe. This led to many Africans being transported to the New World as slaves to do skilled and unskilled labor, this was the Atlantic Slave Trade.
Photo by WELS.net
-The slaves were sold by Africans to Europeans. From 1500 to 1880 about 12 million African slaves were transported to the Americas and forced to work there. Such were the conditions that about 15% of them died during the journey. Slaves were treated as commodity, were overworked and children born to them became the legal property of their owners.
