Neptune has six known rings. Voyager 2's observations confirmed that these unusual rings are not uniform but have four thick regions (clumps of dust) called arcs. The rings are thought to be relatively young and short-lived. Neptune has 13 known moons, six of which were discovered by Voyager 2.
Why was slavery introduced to the English colonies? Slavery was introduced to the English colonies because people were  in need of labor to develop the lands. There was a lot of work to  be done, and there was little money toâ¦ pay for labor. The human  trade was a solution to the issue. Although, this was not a humane  practice.
Around 1619 the first African slaves set foot to the colonies for their first time. Slaves were necessary to maintain the economy growing because tobacco, sugar cane, cotton, and rice become drawing of outline crops in the south.eanwhile, Americans were developing an intellectual framework to help the economic reality. Additionally, slavery lasted until the Civil War, and parts of this racial caste system have continued well into today (Schultz, 2012, p. 52).
