A Butterfly Beats its Wings

Apparently, in Mumbai, India, there is a predominantely Zoroastarian population who believe the only way to ensure their dead departed's souls leave this earthly plane is to leave them on a big mound for the local population of vultues to consume. There is, though, about 10% of the vulture population left; the rest have been decimated after eating cow carcasses which had been given a certain painkiller drug. The bodies are piling up, those in the morgue awaiting a place on the mound, have been waiting for up to a year in some cases (and the morgue is getting full), and the bodies are ... well, starting to smell bad. So what does a pharmaceutical company's marketing efforts have to do with Zoroasatarianism?
