The International Labour Organization (ILO) has estimated that more than 215 million children worldwide are child labourers. This means that more than 1/6 of the children of the world are child labourers.

Child labour is often defined as work that deprives children of their childhood. If refers to work that is physically or mentally harmful, interferes with schooling and can range from paid work to slavery conditions.

Children often work operating tools and machinery, and in mines, farms, and plants. They are often exposed to chemicals, violence, and dangerous working environments which lead to disease and injuries.
