The Lébou people say that not knowing is bad, but not seeking knowledge is worse. Travel in the modern world is an ethical minefield of terms like ethical tourism, responsible travel, fair trade travel.
A larger number of people are now travelling to experience more than just the all sensory touchables like new sights, sounds, smells, and tastes. What travellers seek today is the real with more interpersonal connections with the locals of an area.
So if you are going to travel the world, avoid the cultural bloopers, get informed, inform others, contribute the maximum while disturbing the minimum, look into Art of New Age Travel or the Travel And Culture section and add your two pennies to ours.
