The documentary "Gringo Trails" directed/produced by Pegi Vail offers insight into how the tourism industry has changed over the past 30 or so years. The film is very well made and shows viewers how tourism may be destroying the world. The documentary takes stories from a variety of different people and applies them to the different ways these stories have affected areas across the world. The story may be slow so you must pay attention. This film will make you respect and appreciate other cultures much more. I would recommend for others.
