I read an interesting article about bananas. What we think of as a banana, as in that picture, is a cavendish.
And all cavendishes are clones of each other. So if a fungus hits one of them, they all get it, and yes we have no bananas, until they come up with another variety years later.

That would be a hot photo, but there are some girls in the way.
