Peak Travel

7 dagen geleden7d ago

Maandelijks+

Travel can do amazing things: broaden horizons, build relationships, and rejuvenate the soul. But often, those experiences come at a cost. This is Peak Travel, a new podcast from WHYY about how travel shapes communities in hot-spots around the world. We’ll share the wonder that comes with exploring new places, as well as the harm that our worst travel habits can cause. And we’ll try to figure out how we can do it better. Each episode transports you to a new destination. You’ll meet the people who call that place home, hear their stories, and come to understand how tourism has changed their everyday lives. Supported by rich, on-location sound from around the world, Peak Travel unpacks the $1.9 trillion travel industry and its impact on people and the planet.

We close by covering strengths and weaknesses of this model and providing some real-life examples.
