Bananas

Even though it can only be produced in tropical and subtropical areas, the banana is undoubtedly one of the most popular fruit varieties consumed worldwide. It's safe to assume that it's also the most popular fruit in the world, making up over 76% of the world's fruit commerce.

Regrettably, that might not last long. The Cavendish type of bananas, which is the most popular in the world, is currently in danger due to a fungal outbreak that we are unable to control. It has been destroying banana plants for almost three decades and is known as Panama sickness. A stronger, deadlier strain of the fungus has only recently spread to more than 20 countries, wiping out 10,000 hectares of banana crops. Moreover, the Cavendish type appears to have a relatively low level of resistance to the illness once it has been contracted.
