Challenges for the People of the Future: Finland, Poland, and Yemen.?
These  are all countries. I can't find their culture, traditions, geography,  ecology and government. How many people lived in those countries 200,  100, and 50 years ago? What is their GDP... Gross Domestic Product and  their survival probability?

I'm really  surprised that you can't find all that stuff on the internet. Like  really surprised! I just googled and found so many things that could  take days to read. You can just google "Yemeni Traditions" for example  (which is what I did) and you'll find hundreds of articles.
