Today is World Tourism Day. According to the United Nations, the tourism sector employs one in every 10 people on Earth, and millions more benefit economically from tourism, though the wealth generated isn't always shared equitably. For tourists, exploring new places and enjoying favorite ones can be exhilarating—but bad behavior can ruin a trip. Keeping an attitude of openness and gratitude, as well as respect for local people and customs while on vacation or a tour can transform the experience. Archbishop Rino Fisichella of the Vatican’s Dicastery for Evangelization wrote in anticipation of today’s observance, “A tourism that respects the person and the environment opens the way to perceiving the goodness of the Father who reaches out to everyone with his love.” It’s hard to imagine a better souvenir than that.
