Let’s assume the worldwide Banana outpdrops to zero in one day. That’s bad, but not what I would call dangerous.
In terms of the food supply, their are several major food crops that are important wheat, corn, rice, soy etc so the loss of a major one would be very bad, but the worldwide food surplus is so mind blowingly vast it would not nessisarily result in starvation for anyone beyond possibly the farmers directly affected in the 3rd world.
And frankly next year you can generally plant something else.
