how did Eli Whitney 's invention of the cotton gin affect the cotton industry
The invention of the cotton gin increased the need for slave labor. There were no automatic machines in the 18th century, so there was a need for people to operate the gins. On the upside, the work was more efficient. Before the cotton gin, the workers could not accomplish a lot in a day; the process consisted of picking each individual seed out of a cotton boll, which was tedious and time-consuming. After the cotton gin, workers could simply place cotton into the gin; it would do the rest.
