The Philippines are China's largest banana supplier. According to taiwannews.com.tw, the Philippines exported 1.16 million tons of bananas to China in 2018.

• When 7 bananas are 1kg than this are 8,120,000,000 bananas
• When there are 200 bananas at a banana bunch than this are 40,600,00 banana bunches
• When harvesting 2 times a year than this are 20,300,000 plants (Mother & Son plant because they bear only one bunch)
• When 1440 plants are at one acre than this are 14,097 acres (= 57,037,362m² = 57km²)
• The city Pilsen has a size of 137km². So when the Czech Republic provides the bananas instead of the Philippines than a little bit less than half of Pilsen would be full of banana trees.
