Travel is irreplaceable. No matter how much you read or learn in school, you can’t capture the real flavor of a place and the people who call it home until you’ve been there. It can feel scary—there are so many unknowns—but taking that risk is part of what makes it so unforgettable. For children, travel is perhaps even more important. Seeing the world’s inequalities first-hand, realizing that any of us could have been born in the slums of Kibera, we learn that there is nothing special about those who are born into privilege. It’s just dumb luck. For those of us who are so lucky, shouldn’t we be doing more to make a difference?
