<H1>Child Labour and Kota Stone: Channel 7 Investigation



Tonight Channel 7 will expose the shocking reality that Kota Stone, commonly used in Australian homes and buildings, is being produced by children in horrific conditions.
Channel 7 travelled to Rajasthan, India with Oxfam Australia?s partner the Mine Labour Protection Campaign (MLPC). The MLPC work to improve conditions for millions of mine workers in Rajasthan whose rights are being denied.

There are approximately 400,000 children working in stone mines in Rajasthan, India in conditions that are defined by the International Labour Organisation as among the worst forms of child labour because it?s extremely dangerous.
Children make up 15% of mine workers in Rajasthan ? they?re paid minimal wages but their families are so desperate for any money they have no alternative but to put their children at risk. This work can cause serious injuries and disease. And without the opportunity to attend school, they?re denied a hopeful future.
