How bangles are made risking people life

It takes dozens of people making a single glass bangle.
The glass is heated in burning hot furnaces at 200°C. After staying for 10 hours in burning furnaces the glass turns into thick water like liquid. This melted glass liquid is taken out by workers. These workers are not wearing any gloves, glasess nor any other safety material. Although the workers wese provided with gloves and glasess but they refused to wore those, because wearing gloves can loosen their hand grip on metal rods and they don't want to compromise on their hand grip. The factory workers also breath in this glass dust. According to a survey 23% of bronchitis is resulted from glass dust in air.
This bangle factory present in Firozabad is 30 miles from Taj mahal. In 2005 the crosion of mahal marble was claimed to be caused by factory smoke. It caused fear of closing of factory but owners were asked to use natural gas instead of coal.
But the point is why bangles are still made this way.
There are hundreds of bangle workshops in Firozabad with thousands of people working in them.
According to workers , the factory is only source of their income. If factory is closed they can die of hunger.
In the factory, the melted glass is rotated around a long cylindrical shaped rod by a small machine to give it a shape. The broken glass pieces are continually sweeped by women to be recycled.
After the molten glass is given bangle shape, it's brought to workshop for ornamental work. Hundreds of people perform this ornamental work for very low wages , 1$ or 2$ by working 7 to 8 hours day. Special paints are used by workers to paint the bangles. Final products are sent to market for sale.
The end product is not expensive. Thousands of such bangs are wore by Indian women on daily basis.
There are 40 to 50 hands behind each bangle.
