Why did the Europeans need slave labor in the colonies?

To work on their plantations, which were their main source of income. The plantations required a lot of really intensive and dangerous work that the colonists did not want to do themselves. They realized that African slaves provided cheap labor and could be easily replaced.

Eventually, the colonists just became over reliant on this slave labor, which is why they “needed” it.
