Can This Fruit Be Saved?

No! Not Ricky Martin.

The Banana!

The banana as we know it is on a crash course toward extinction. For scientists, the battle to resuscitate the world’s favorite fruit has begun—a race against time that just may be too late to win.

...
The Cavendish—as the slogan of Chiquita, the globe’s largest banana producer, declares—is “quite possibly the world’s perfect food.” Bananas are nutritious and convenient; they’re cheap and consistently available. Americans eat more bananas than any other kind of fresh fruit, averaging about 26.2 pounds of them per year, per person (apples are a distant second, at 16.7 pounds). It also turns out that the 100 billion Cavendish bananas consumed annually worldwide are perfect from a genetic standpoint, every single one a duplicate of every other. It doesn’t matter if it comes from Honduras or Thailand, Jamaica or the Canary Islands—each Cavendish is an identical twin to one first found in Southeast Asia, brought to a Caribbean botanic garden in the early part of the 20th century, and put into commercial production about 50 years ago.
That sameness is the banana’s paradox. After 15,000 years of human cultivation, the banana is too perfect, lacking the genetic diversity that is key to species health. What can ail one banana can ail all. A fungus or bacterial disease that infects one plantation could march around the globe and destroy millions of bunches, leaving supermarket shelves empty.
