This picture shows children that were working in a coal mine. This is how child labor looks like. Child labor needs to stop because children need to go to school to get an education instead of working. Child labor began when factory owners viewed children as more manageable, cheaper, and less likely to strike.
"Over 100 million children around the world work in hazardous conditions in agriculture, mining, domestic labor, and other sectors. On tobacco farms, children work long hours in extreme heat, exposed to nicotine and toxic pesticides that can make them sick. In Africa, Asia, and Latin America, child laborers in artisanal and small-scale gold mines work underground in pits that easily collapse and use toxic mercury to process the gold, risking brain damage and other serious health conditions. We are working to end the worst forms of child labor and to ensure that all children are protected from jobs that interfere with their health, safety, and education."
