Why was slavery so common in the south

Hi,

The south relied mostly on crops and planting.

My work: Slavery was common in the south, because the south had a lot of plantation and somewhere along the way a industrial planter brought slaves to the south which started slavery in the south.

I Hope I Helped!

the answer to fill in the blank in this question would be the word resource, it is defined as the money, material or people (since human resource is a very valuable good) that a company or a person has at disposition (meaning they can use the resource as they see fit), to be able to complete a task or achieve a goal.  

i would think i'ts d hope this out
