Young Sanjay and his friends have abandoned their fertile northern India farm fields and taken up a more dangerous line of work: collecting copper powder by submerging discarded circuit boards in nitric acid, and selling the usable leftover materials to factories.

Their harvest, however, is anything but sustainable: it poisons their lungs and the land that used to provide for them.
