An impending banana crisis?

Tyler Cowen relays some disturbing news:

It turns out, by the way, that the world's supply of Cavendish bananas -- the ones we eat -- is endangered by disease (more here) and many experts believe the entire strain will vanish. Most other banana strains are much harder to cultivate and transport on a large scale, so enjoy your bananas while you can. The previous and supposedly tastier major strain of banana -- Gros Michel -- is already gone and had disappeared by the 1950s, again due to disease. Today, European opposition to GMO is one factor discouraging progress in developing a substitute and more robust banana crop.
