One does not require flashy Powerpoint slides or state exact statistical numbers to be able to convey an educational yet compelling presentation. Nor should the presentation need to take that long.

Hans Rosling, who is already known to use physical props during his presentations, ranging from IKEA storage boxes, over washing machines to a real sword, demonstrates again how physical objects can be used to focus human attention to important statistical trends. He also shows how stones can convincingly form bar graphs.

The following 'talk', taking less than 50 seconds, 'happened' during a spontaneous interview after the TEDxSummit 2012 in Doha, Qatar and discusses the impact of global population growth.

Watch the presentation below. The presentation also reminds me to always show up with clean shoes.

He poses probably the most important question for anybody who's thinking about the future of human life on this planet.

We need to make decisions with this in our minds - it transcend everything.

Thank you Hans !

Rosling forgot to add new columns. Wealth is relative, saving for a trip abroad this year may become a trip to space in 10 years. Do we need shoes in space?
