Some of the effects of exploration are slavery, new resources, and even new land. Slavery came about when Columbus went to the America’s and found the natives and forced them to work for him. Slavery was very popular for the Europeans, they decided that slavery was the new best thing. The Europeans thought that slavery was okay and they were too lazy to do their own work. The worst of all though is they sold them, which is pretty bad considering it’s not their lives to sell.
