Seven billion people spread across seven continents. Sure, it’s a small world – but almost 60 million square miles of land is still plenty to get lost in. And a population of billions that’s still rising? That’s easy to get lost in, too. Check the statistics: every single second, four babies are birthed into this world. Every half second, a fellow human being dies. The numbers are easy to understand; it’s when I try to imagine the reality behind the numbers that my mind begins to spin. I look around at the world and feel very, very small.
