The three words are scrawled everywhere; on walls, banners, and even on the side of Barcelona's rubbish bins. It's easy to dismiss them as the word of isolated cranks. But it isn't. The message increasingly reflects popular sentiment, and not just in the tourist hotspots in Spain. And with short-term rentals like Airbnb driving locals out of their apartments, while the digital nomad ghettos as distant as Chiang Mai and Medellin, cause skyrocketing prices out of the reach of residents, it's impossible for a sincere traveler not to ask the question: Are we part of the problem?

Daniel Maurer wrestles with the big questions, such as this, in his new book The Future of Travel, part of an intriguing 'Futures' series by Melville House. Daniel is an award-winning food, culture, and travel journalist who has written for outlets such as The New York Times, New York magazine, Thrillist, The Art Newspaper, Eater, The Daily Beast, Atlas Obscura, and others. He won two James Beard Media Awards while chief editor of Grub Street.

Daniel joined the Travel Writing Podcast to speak about overtourism and traveler's guilt, and how we can keep traveling without causing harm to the places we visit.
