Dear C., It's so weird how little I know about the food I eat. Just read an article about bananas, the kind you buy in a supermarket, which are apparently called Cavendish bananas and are expressly considered "commercial". Apparently, commercial bananas are under threat due to their lack of genetic diversity, making them prone to fungal diseases -- another variation, "Big Mike", went the way of the buffalo in the 60s for the same reason. I am not certain about the suggestion that wild bananas be used to produce new variations, tho. I have a hunch that this would drive the cost of bananas up, which is concerning. It might be possible in someplace like the U.S., where we have money for R & D, but I worry about how this would affect people in poorer countries.
