Interesting Food - Bananas

The Cavendish variety of banana accounts for 95 per cent of bananas shipped to export markets around the world.

(That's interesting in itself, but the biggest nightmare of a monoculture has arisen, and the world’s banana crop is under threat from a fungus; Foc-TR4. According to Nature, a strain of Foc wiped out the Gros Michel cultivar, which was the main exported banana variety until the 1950s. Gros Michel plants were then replaced with the Cavendish variety, which is resistant to that Foc strain, but susceptible to the new Foc Tropical Race 4 (Foc-TR4) strain.

The disappearance of bananas from supermarket shelves in the UK is one thing, but bananas form a crucial part of the diet of more than 400 million people.)
