Forbes just published their List of the World's Billionaires. The 100 wealthiest people have a combined worth of over 1,705 billion dollars. Billion! That's enough to give $250 to every man, woman and child on the planet (or buy everyone a Nintendo 3DS) and still have a few billion left over.
On the other hand, the world's 100 poorest people have a combined wealth of ... well, zero. According to United Nations data, about 925 million people, or roughly one out of every seven, is undernourished.
