The problem of child labour is inter-linked with various socio-economic conditions. Poverty is considered its main cause, which leads to illiteracy, low productivity, poor health and low life expectancy. Some of the industries that depend on child labour are match and fireworks, bangle-making, beedi-making, power looms and manufacturing processes using toxic metals and substances, such as lead, mercury, manganese, chromium, cadmium, benzene, pesticides and asbestos. A certain number of child labour is also found at brick kilns, handicrafts-making, silk and silk products, soldering processes in electronics industries and on floriculture and vegetable farms. Child labour is an evil that must be eliminated.
