Measuring the world with rice

1 Rice = 1 Person

The creator of the unusual exposition use an idea pretty simple: one grain of rice for each person in this whole world. When visitors walk by the lobby, they can see piles of rice with different sizes that helps to visualize statistics about the world.
For example, one pile represents the demography of a country. Other pile is about children that will be born in this world in the next 24 hours. When we visualize the different sizes, it helps to see different proportions that we can’t see just with numbers.

Some of this piles shock our mind by its impact visual. One big pile represents the people died in the Holocaust. Other one, amazingly big, represents the children in the world with hungry. And this third one...

...Represent the children that will be die in the next 24 hours by malnutrition :/
