One of the best documentaries I have recently seen - a humble scientist from Sweden explains many interesting facts, like how many child are born for woman in average, does Asia and Africa is overpopulated?  Scientist explains how medicine and education have provided longer life expectancy in countries like Bangladesh.

In this documentary is shown  a beautiful story about African family living with less than $1 day and dreaming to buy a bicycle. And how bicycle literally drives them out of extreme poverty.

About energy consumption. About the Riches and Poor.
