Why did slavery grow in the south colonies?

The earliest settlers of the South saw that there was great money to be made by growing labor-intensive cash crops - sugar, tobacco, cotton, rice, and indigo in particular. The climate was perfect, and the riverine geography of the Tidewater made transporting bulk crops grown inland to the Atlantic Ocean for export to Europe feasible

Explanation:

indigenous people north and south were displaced, died of disease, and were killed by europeans through slavery, rxpe, and war. in 1491, about 145 million people lived in the western hemisphere. by 1691, the population of indigenous americans had declined by 90-95 percent, or by around 130 million people."

the answer should be arrogance & pride.
