I'm happy to notice that "Unaffiliated", ie no religion is the most youthful group, with 31% being age 18-29 - higher than for any other group. 
 
Or then they haven't decided yet...

Neziha: "The problem is, people cannot be globalized and maintain -any- quality of life. People are territorial. Moving is -traumatic-." 
 
That shouldn't be the case. Hunter-Gatherers moved all the time. We should be "genetically used to it".

For anyone with intersecting interests in Economics and GNXP-type topics, a book called "Keynes on Population" by John Toye (Oxford University Press) can be interesting. 
 
It revises Keynes' (but also Marshall's) recorded views on population, eugenics, race, and similar issues. If I remember correctly, Keynes was not very enthusiastic on eugenics in the UK, but typically viewed most of the world's population with the standard stereotypes of the time, with logical implications in terms of policy. 
 
Another book that I'd like to recommend is an "insider view" to how Economics as a science progresses. This is "Conversations with Leading Economists" by B. Snowdon and H. Vane. It consists of 14 interviews of top-notch macroeconomists, who tell how their careers and thinking have developed. I think many macroeconomics courses would benefit a lot by having this book as a parallel text. 
 
Both of the books are fairly easy on the readers, and can be read in several bits.
