How did the search for water route to asia affect both europe and the americas?

Christopher Columbus wanted to go to Asia but their navigation was not that great so he ended up in America. When he got to America he started to sail back goods that were in America to Europe to the Americas. That's how America got horses, cows, and pigs. They also got other things like oranges, sugar cane, and disease.

Hope this helped :-)

The answer would be option a , b, and c.
