Have you ever visited Our World in Data? If not, do so. It is a project in continuous development by the Oxford economist Max Roser, who has taken as his task to educate the world through easy-to-digest graphs and statistics. I will not bother you by re-telling his take on the history of hunger, more than that we have made significant progress, which of course is encouraging in the context of a world Expo all about food. You can find the online presentation here and more on Max Roser here.
For entrepreneurs it might be worthwhile to take an extra look at the datasets. After all, information is the backbone of any enterprise and here it comes very well packaged.
