I think it's worth pointing out that this story crops up every few years and it is always sensationalized. Not saying it couldn't be a problem but I think people read too far into it.

Among other things the Gros Michel  banana is not extinct. It is just no longer in large commercial production. It was easy to start growing Cavendish bananas then deal with the root rot.

I'm interested to see the next flavor of banana.

Fun fact - artificial banana flavoring tastes more like the Gros Michel banana. So when you have banana flavored candy, you are tasting what a banana used to taste like back when the Gros Michel was the dominant banana variety.

I mean an easy but not as profitable way (because profit matters more than literally anything apparently) is to stop growing bananas as a monoculture

The extinction of the George Michael was the most tragic event in recent history. I can't bear to see history repeat itself.

Cavendish bananas are so bland. Wish we could get more different varieties into supermarkets worldwide.
