You know that goofy old song “Yes! We Have No Bananas”? It’s based on the fact that the most popular variety of bananas in the early 20th century, Gros Michel, was nearly wiped out by a banana tree killing pathogen. The older banana type was sweeter – in fact, artificial banana flavor tastes just like it. Today’s bananas, the Cavendish variety, are blander in comparison but they had one great benefit—they were resistant to the banana blight.
But nature always finds a way, and now the Cavendish are in danger of dying out thanks to a new superstrain of the blight. Bananas as we know them now are so dependent on human interference, they don’t even reproduce naturally anymore (we bred the seeds right out of existence). All we can do is find another banana that can resist the new fungus or just lose them as a crop forever, and then yes, we really will have no bananas.
