Hans Rosling on global population growth

Here is the link for the presentation Patrice told us about.  I thought it was a very good delivery in spite of his strong accent, meaning that one can really pull it off, even though s/he is not a native speaker. He also presents quantitative data in a very accessible way for a layman.  He definitely made an impression on me, and I can share the information he provided me with at a cocktail party :-) What do think?
