Here an excerpt from Amazons' review:
In honor of the United Nations-sponsored International Year of the Family in 1994, award-winning photojournalist Peter Menzel brought together 16 of the world's leading photographers to create a visual portrait of life in 30 nations. Material World tackles its wide subject by zooming in, allowing one household to represent an entire nation. Photographers spent one week living with a "statistically average" family in each country, learning about their work, their attitudes toward their possessions, and their hopes for the future. Then a "big picture" shot of the family was taken outside the dwelling, surrounded by all their (many or few) material goods.Also an optimistic take from a blog about US garbage problem called Garbage Land, which gives great advice on what we can all do.
