The Columbian Exchange refers to the exchange of plants, animals, and diseases caused by contact between the Old World (Europe, Asia, and Africa) and the New World (the Americas). This biological exchange began with Columbus's arrival in 1492, and continued as Europeans continued to explore and come into contact with people, plants, and animals in other parts of the Americas that had not been exposed to European diseases, plants, and animals. An end date is harder to pinpoint. Since the Exchange refers to items that at one time had never been outside of their original hemisphere, once the biological elements that were once unique to their specific hemispheres had been introduced to the other, that exchange would assumedly be over.
I think there is a million plants & animals still undiscovered Do not take my word for it
They have been around for 6000 years :) The reson for this is because animals were introduced Way before humans were on land.
