Are Hindus Losing their Reverence for Cows?

Are Hindus losing their reverence for cows?  That’s what Fred de Sam Lazaro suggests in this clip from PBS Religion and Ethics Newsweekly. He notes that over 40,000 cows roam the streets of Dehli and “are increasingly seen as a nuisance, clogging traffic and foraging through garbage heaps.”

But why are cows revered in the first place?  This is what make the clip so interesting,especially to students. De Sam Lazaro interviews a number of Hindus who explain the significance of the cow in Hindu culture.
