paragraph_text: The Missouri makes a bend to the southeast as it winds through the Great Plains, receiving the Niobrara River and many smaller tributaries from the southwest.

Downstream, it begins to define the Nebraska -- Missouri border, then flows between Missouri and Kansas. The Missouri swings east at Kansas City, where the Kansas River enters from the west, and so on into north - central Missouri. To the east of Kansas City, the Missouri receives, on the left side, the Grand River.

paragraph_text: Children working at a young age has been a consistent theme throughout Africa. Many children began first working in the home to help their parents run the family farm. Children in Africa today are often forced into exploitative labour due to family debt and other financial factors, leading to ongoing poverty. Other types of domestic child labour include working in commercial plantations, begging, and other sales such as boot shining. In total, there is an estimated five million children who are currently working in the field of agriculture which steadily increases during the time of harvest. Along with 30 percent of children who are picking coffee, there are an estimated 25,000 school age children who work year round.

paragraph_text: Home-based manufacturing operations were active year round. Families willingly deployed their children in these income generating home enterprises. In many cases, men worked from home. In France, over 58 percent of garment workers operated out of their homes; in Germany, the number of full-time home operations nearly doubled between 1882 and 1907; and in the United States, millions of families operated out of home seven days a week, year round to produce garments, shoes, artificial flowers, feathers, match boxes, toys, umbrellas and other products. Children aged 5–14 worked alongside the parents. Home-based operations and child labour in Australia, Britain, Austria and other parts of the world was common. Rural areas similarly saw families deploying their children in agriculture. In 1946, Frieda Miller - then Director of United States Department of Labour - told the International Labour Organisation that these home-based operations offered, "low wages, long hours, child labour, unhealthy and insanitary working conditions."

paragraph_text: Small-scale artisanal mining of gold is another source of dangerous child labour in poor rural areas in certain parts of the world. This form of mining uses labour-intensive and low-tech methods. It is informal sector of the economy. Human Rights Watch group estimates that about 12 percent of global gold production comes from artisanal mines. In west Africa, in countries such as Mali - the third largest exporter of gold in Africa - between 20,000 and 40,000 children work in artisanal mining. Locally known as orpaillage, children as young as 6 years old work with their families. These children and families suffer chronic exposure to toxic chemicals including mercury, and do hazardous work such as digging shafts and working underground, pulling up, carrying and crushing the ore. The poor work practices harm the long term health of children, as well as release hundreds of tons of mercury every year into local rivers, ground water and lakes. Gold is important to the economy of Mali and Ghana. For Mali, it is the second largest earner of its export revenue. For many poor families with children, it is the primary and sometimes the only source of income.
