The World's Biggest Problem 

There are an estimated one million children enslaved in the world, as we sit here. That's a problem. And with them, twenty-nine million other slaves who don't qualify as children anymore. More than at any other time in history. And as if that wasn't problem enough, they are joined by two hundred and ten million orphans...
And then there are other tragedies. Like superstorms, and droughts, and famines, and diseases. And despots, and corrupt governments, and brutality, and crimes against humanity.
But these are not nearly the world's biggest problems.
Not even close...
