The banana is facing extinction within the next 10 years due to lack of genetic diversity. All modern bananas are clones of the Cavendish variety, making them vulnerable to disease. Panama disease, which has already wiped out the previous dominant Gros Michel banana, has evolved into a new deadly strain that is spreading. If the Cavendish banana falls to this disease, it could devastate economies and jobs worldwide as bananas are a key crop. Scientists are working to develop a genetically diverse and resistant replacement banana but it may be too late to save the Cavendish.
