 The positive and negative effects of the Columbia Exchange are really supported and they helped us today.  A positive effect is that widespread crops and livestock that supported the increase in population throughout the regions. One of the negatives is that slavery and communicable diseases. This was not really supported because because of this many people were taken and never returned. Sometimes many people enter slavery to fight for their family members.

Slavery was the biggest con they had because most of the time they didn't want to leave but had to or they would die. Most people today are thankful for the people who got rid of slavery. These are some thing that are positive and negative .
