What was the Colombian exchange?
The Columbian exchange was the event of how the old world and the new world had trade routes so that they could bring positive effects,but also negative effects.One of three positive effects are new plants,different foods,and animals.Three negative effects were bacteria killing plants,new animals and plants using all of the nutrients used to survive,and diseases killing us all.
Don't risk it what is on the other side.
What is on the other side i mean yeah there is good stuff but what about everything else there could be despises that kill us all why should we take the chance sure it gives us positive thing but what else is on live do not take the chance for america we will make the people after us have a esair life.This is why we should not have the columbian exannge.
