Or how to preserve nature while installing "buildings"?
The first example chosen to support this question is that of Cliffs of Moher. Why choose the Cliffs? Simply because I went there!
So, Cliffs of Moher is very well known in Ireland for its famous cliffs, but less so for the Visitor Center, which is a new addition to this tourist site. In fact, it's barely distinguishable from the surrounding environment...
In addition to blending into the environment, the structure was built into a cave and is almost energy self-sufficient: it uses geothermal energy, photovoltaic panels, water recycling... and it's also a friendly place!
And the center also practices composting to truly reduce its impact on this magnificent site...

I believe that in a site like the Cliffs of Moher, this center is truly the solution, as it encourages tourists to adopt a sustainable approach and also shows other sites that yes, it is possible to do business (because this center contains shops and a restaurant) while preserving the environment.
The only negative point is the buses, because during my Irish trip we had decided to visit everything by bus and unfortunately there aren't many... so we reduce on one side... However, many people also come by bus, but buses filled only with tourists... well, that's another debate!
