Ellen Fanning in The Global Mail:
Here's a pop quiz for you. What is the adult population of North America?
A few years ago, the official number was around 260 million. But the more accurate figure may be some 30 per cent higher — closer to 340 million. To be brutal, it's because so many of them are so fat.
London researchers have put the world's population on the scales and worked out that so many people are overweight or obese, they are effectively making the planet much more crowded.
If every nation's population was as fat as America's, they reckon, it would be the same as having about an extra billion bodies on earth.
