Southern planters begin to purchase slaves from the 1660's for all of the following reasons, EXCEPT:

Southern planters saw the large slave populations in the Northern colonies as a clear example to follow

The supply of indentured servants was in decline and thusinsufficient to meet plantation labor demands

Indentured servitude involved continual turn-over of the
workforce, and the re-discipline of new workers to arduous plantation tasks

African slaves were less expensive since the British Royal Navy established a direct trade route from Africa to the British colonies

Southern planters saw the large slave populations in the Northern colonies as a clear example to follow

Explanation:

Southern planters did not purchase salves from the 1660's onwards because they saw large slave populations in the Northern colonies. The reason why is that the Northern colonies never had such large slave populations.

Some states did have a considerable slave population: for example New York and Pennsylvania, but it never reached the scale of the Southern planations.

The reason why is that the Northern climate is not suitable for those plantations, and as a result the economy of the northern states was based on othery types of agriculture.
