Why was slavery common on southern plantations, and how did it affect laws in the southern colonies?

Slavery was common for various reasons. One of them being climate when the british brought them to america they figured they were used to the heat and moisture. Another was the plantations required alot of attention. They didn't see the africans as equal so they let them sleep around the plantations in barley inhabital places. Another obvious reason is the fact that the southern colonies were on the coast of the Atlantic as was africa so it was a much easier to put the slaves there.

the andes or andean mountains (spanish: cordillera de los andes) are the longest continental mountain range in the world, forming a continuous highland along the western edge of south america. this range is about 7,000 km (4,300 mi) long, about 200 to 700 km (120 to 430 mi) wide (widest between 18° south and 20° south latitude), and of an average height of about 4,000 m (13,000 ft). the andes extend from north to south through seven south american countries: venezuela, colombia, ecuador, peru, bolivia, chile and argentina.
