don't support it
We didn't forget the bad stuff.
Good things happened in the exchange but I don't think we will ever forget how good it is to not have diseases with us.
Some good stuff happened and we discovered a lot of things we never seen before in America. We now have a lot of good and healthy food that we would not have if they never came.
They brought diseases, and they couldn't get food and a lot of them died.
Their were many good things that we discovered with the exchange, but their were bad things too.
