What occurred during the Colombian Exchange

The Colombian exchange was a triangle of an exchange of goods from the east side of the world, including Europe, Africa, and Asia with the new America's. Goods such as animals, crops, and even diseases were being sent to the new world from the old world, and the same was being sent to the east world from the new world.

Basically a triangle between the Atlantic Ocean shipping foods and animals to grow and raise them new in the new fresh soil of the new world.
