In the year of 2010, I had the privilege of visiting one-kilometre-wide turquoise colour lake known locally as Kawah Ijen, located at Central Java, Indonesia. Intensive sulphur mining is operated by employing cheap labours from the localities. The miners look like the modern hulks, moving closer will reveal how badly they are affected by excessive exposure to sulphur. The above picture tells a group of miners carrying heavy loads of sulphur, usually at the weight of 75 to 90 kilos through the foggy morning I was there. Cheap labour they were and still are, earning only IDR50,000.00 to IDR75,000.00 per day.
