For strong bones, girls need plenty of calcium and vitamin D and lots of physical activity every day. The amount of calcium in a food may be a little more or a little less than what is listed on this chart. This is because different brands sometimes have slightly different ingredients. Check the food label to see how much calcium is in the food. Aim for 1,300 milligrams or 130% of the % Daily Value (%DV) every day.
In the British colony of Carolina (located mostly in what is now modern-day South Carolina), black slaves worked on large plantations and soon grew to outnumber the white population of the region by two to one (Mason 2006).
The economy was largely agricultural and long-m exposure to black slaves in the south had led many people there to conclude they were inferior to whites. Abolishing slavery would mean that every slave holder would lose their investment. The economic devastation from that would not have been tolerable. The north had a shorter crop season than the south, so slavery was economically less feasible. The south were able to produce two crops a year, the north only one because of the onset of winter. I'm sure there are other factors but this one was probably the biggest. Artorius Â· 8 years ago.
