Hello, I'd like to learn about Switzerland!
Sure thing! Switzerland has over 1,500 lakes and contains 6% Europe's fresh water.
Awesome! Could you tell me a little more about the geography?
Absolutely. Switzerland extends across the north and south side of the Alps in west-central Europe and has a great diversity of landscapes and climates on 41285 km2.
Sounds beautiful! Switching to something less appealing... got any information about the politics?
I do, actually. The populations tend to vary between 16,003 in Appenzell Innerrhoden, 1,487,969 in Zurich, and the area between Basel-Stadt, which is 37 km, and Grisons, which is 7105 km2.
Interesting. Got any other info regarding politics in Switzerland?
Yes. Switzerland, is not a member of the European Union because the Swiss people have consistently rejected them since the early 1990s.
What the crap, European Union? So rude. I wonder why?
I'm not sure, but I can tell you that Switzerland is a member of the European Free Trade Association (EFTA).
Great. Thanks so much for your help today!
You're very welcome. Have a great day!
