Pica

People diagnosed with this debilitating disease have an insatiable urge to eat things normal people wouldn't even consider. Think inanimate objects like dirt, paper, glue, clay, mud, glass and even feces! Experts believe it is linked to a mineral deficiency, but the truth is that even today, no real cause or cure has been found for this disorder. 

Strangely, many children in Bhopal have been born with this disorder repeatedly ever since the Bhopal Gas Tragedy. Having said that, so far, no link between the two has been found.
