Example from the list:
Slavery is now illegal in every country in the world. Such bans also extend to forced labor and human trafficking. The problem is that there are today more slaves in the world than ever before. An estimated 30 million people are trapped in slavery. Of those, the largest number of slaves are in India, with up to 14 million slaves.
Scoop’s note:
Er … not quite
Not only is slavery still legal in the United States, but it is specifically allowed in the constitution. The 13th Amendment allows slavery “as a punishment for crime whereof the party shall have been duly convicted.” As the result of this constitutional loophole, there are still states that require able-bodied inmates to work without any compensation. Three examples are Arkansas, Georgia and Texas.
As noted in the comments, there is also a very fine line between military conscription and slavery. Under some reasonable definitions, there is no line at all. Slavery can be defined as “forced labor without compensation,” but many would argue that any forced labor is slavery, irrespective of compensation. By that definition, military conscription is not only a system of slavery, but a system that places those slaves in life-threatening conditions. Mandatory military service is still in effect in many countries and was not abolished in the USA until 1973.

People who are from some countries that have conscription are practicallly slaves
Fun Fact: In 1973 or 1974, I still had to register for Selective Service. I had my “draft card” for many years, and it may still be around somewhere now. I was classified 1H, which was a holding category, but I always stole from Woody Allen and said that it meant that in the event of war, I was a hostage.
There was only one brief period in the mid- to late- 70s when when registration for selective service was not required. You must have had to register just before that period began. The registration began again circa 1980 and continues to this day.
I still have my draft card or cards around somewhere. I think I was 1-H, then 1-A. Despite my 1-A status, I was never drafted because of a high number in the so-called draft lottery.
graduated high school in 1974 and very well remember dreaming up exemption plans until they dropped the draft. I did have to register but was not issued a card
Slavery is still practiced in the NBA. You have players complaining about their owners and being forced to play games. But some players say they have good owners.
To meet the definition of slavery, the situation requires that the slave can’t escape his labor. Slaves can’t quit. The NBA players can quit any time they like.
Well number 1 “Slavery in the territory now known as the United States began in 1619 when 20 African ‘servants’ arrived in Jamestown, Virginia on a Dutch ship. ” is patently false.
Several Indigenous/native American cultures practiced slavery well before the arrival of Europeans, and many groups were still doing so up until the 13th Amendment.
Good point.
(Although I think their problem was poor wording rather than poor history. I think they meant slavery among the colonists whose descendants would form the USA.)
I suppose we really don’t know when enslavement began in the area now known as the USA, and can’t even venture a good guess because of the lack of written languages among the indigenous people, but my speculation would be “almost immediately after humans arrived.”
