As she cleans the carbon rods from exhausted D-cell batteries, Marjina holds her young child on her lap and gently lulls her to sleep. Marjina migrated from the countryside to Dhaka, the capital of Bangladesh, with her son and four daughters after her husband died. Now she toils every day in a workshop by the Buriganga River that recycles used batteries. Wiping tears from her eyes, Marjina tells me, "Regardless of how hard my children and I work, we accumulate more and more debt every month. I don't know what to do. I have nothing that I can sell to pay off my debts." http://edition.cnn.com/2008/TECH/science/09/28/what.matters.dust/index.html#cnnSTCText Labels: What matters.
