In 2009, 95,595,965 metric tons of bananas were harvested. Given that the average banana weighs about 120g, that comes to about 796,633,041,700 bananas. So three billion bananas is about 0.37% of the bananas produced in a single year. The country that consumes the largest amount of bananas per capita is Uganda, where the annual per capita consumption averages about 225 kg per person. It is made into "matooke", a dish of mashed boiled bananas, which is the staple food amongst the Baganda. Uganda is no small country; in fact, it's the 35th most populous country in the world. The population of Uganda in 2016 was 41,487,965 people. That means that some 9376280090 kg of bananas were consumed in Uganda in 2016. That translates to about 78,135,667,416 bananas consumed in Uganda in 2016. Three billion bananas is 3.8394% of that. All I'm saying is this number seemed impressive at first, but it's not like a major banana importer-exporter is going to have lima pisang in stock or anything.
