Compare the slave trade of colonies to modern days

Well when the slave trade was going on a lot of people were being held back for slavery and it was a hard time now a days slavery is done/ended and we still have a little bit of things going on but not a lot

People used other human being as their pets a.k.a slaves now slavery comes in different forms such as bosses taking control of their workers but the workers at least get paid

These islands/chinampas then provided rich soil for crops with easy access to water. i hope this is correct, im so sorry if its not !
