Could veganism end world hunger?

It's one thing to not care about or recognize the connection between the food on the plate and how it got there.  But to understand that world hunger could all but end if the West adopted a meat-less diet should (I'd hope) encourage more people to go veg.  

And this CNN story makes a persuasive case for veganism.  There are finite resources that we all need to share and the massive amounts of grain consumed by animals raised for food could be put to much better use nourishing starving families around the world.  I hope reading this spurs people to pledge to be veg.
