Why Did The Slave Trade Last So Long

The last question I have to answer with evidence is “Why did the slave trade last so long and what values were found in the slave trade?” An evidence I have is from “Roots” it is, in Roots while they were sailing to the new land they had a flood. The flood caused the tobob to close the air vents and they couldn’t get any fresh air, many of the slaves ended up dieing. As a result, they had to take very good care of the slaves they ended up with so they can make the whole experience worth the money they get in the end. The Cruelest Commerce text said that the slave trade took so long “because of tropical diseases there's was always a very heavy demand for new new African slaves in Central and South America.” A value in The Cruelest Commerce is
“in 1700s the slaves received better medical care, and diet and sanitary conditions improved.” Thus, every slave was sold for a higher cost because they were so healthy and they lost a lot of slaves so they couldn’t get as much money as they hoped for. A value for the slaves in Boarding a Slave-Ship is “They gave me to understand we were to be carried to these white people’s country to work for them. I was then a little revived, and thought, if it were no worse than working, my situation was not so desperate.” Regarding, that he has most of his stress off of his shoulders as he knows now he will only be working, he still fears that he would be killed. Finally, the Atlantic slave Trade had both values for everyone but mostly the white people.
