The cotton gin made it so seeds did not have to be individually picked by the slaves. This saved hours upon hours of work, and it made it so less slaves were needed to process the cotton. All the slaves had to do was put the cotton into the machine and the seeds would get pulled out. It actually increased the demand of slaves instead of diminishing it. You would think since less slaves were needed to process the cotton, there would be less demand.

It majorly impacted the slave industry, which was a major problem in America at the time.
