Thank you for this reminder. 25 years ago a book was put out by Peter Menzel titled "Material World" and various international societies were filmed with all their possessions. One important feature was how many had TV's. Later, another similar book came out which focused on food. This time the toilets were shown. Informati0n as this should be required in the public (forget the religious schools) schools.

Zero Population Growth had many activities for different age ranges. One activity we used for teachers was called "Food For Thought" and had a similar theme in dividing a class into 5 continents, arranging students according to the continents population and showing certain resources available to the citizens of each continent. This was a real eye opener for the teachers and students who participated. I actually have a kit to give this demonstration. [populationeducation.org]

Really interesting talk. Thanks for sharing.

The big cultural difference it seems is not between countries, but between income.
