This article is mostly about overcrowding but another important consideration is carbon footprint. The carbon footprint of tourism is a big blindspot in the "liberal" mindset (speaking as one). On the one hand travel is supposed to be good and healthy for your development and the broadening on your mind.. Anthony Bourdain.. listen and exposure yourself to cultures.. etc. On the other, air travel is 100% fossil fuel based. Flying to Europe from SF is like driving coast to coast in a gas car. We could use a healthy backlash against the idea that everyone should strive to fly around the world. Sustainability must come first. This is a bitter pill for us "liberals" to swallow, I think.
