Child labour is common at the brick factories where the parents work as labourers, desperate to make more money enlisting their children to help doing the easy jobs. Brick factories are an economical, business that is still thriving. The land used is dry and barren which is perfect for the making of bricks providing work almost all the year round. A few years ago all factories changed from wood to coal causing further problems with pollution, the factories have been pushed out of the city limits because of this issue.
