Hidden cost of mining in Goa

Few are aware that Goa is one of the biggest exporters of iron ore in the country. And while this has been an economic trigger for the state, it's come at a cost to Goa's ecology and local residents. Nearly 70 mines that stretch across the state work overtime to dig up half a country's iron ore exports. The boom in Chinese demand has seen extraction doubling in just five years - from16 million tones in 2001 to 30 million tones in 2006.
