Crushing pollution

2019-12-17 · Stone-crushing is a profitable business in the mountainous regions of Bundelkhand and around 600 stone crushers are operational in the region. Just like the mountains gave refuge to dacoits to carry on their operations almost unhindered, the stone crushers also benefit from the isolation of the region: little attention is paid to law.
