Answer:
Removed potential slaves / Allowed for more farms to be built on sacred land
Step-by-step explanation:
When the natives were removed from the southern colonies, people weren't able to enslave and force work upon the tribes there, this would result in farmers requiring slaves to be purchased from continents such as Africa. Since all the natives were forced out of the area this also left their land open. With all this new land available for farmers the need for slave workers increased with it.
