today's banana and it's rather bleak future - which happens to be a damned good argument FOR natural selection. I took them off of my shopping list years ago. Too damned many nasty pesticides used in production.

With its DNA frozen in time, the hapless banana has not been able to modify itself genetically through natural selection to fend off pests and bugs that have appeared in the past 100 centuries. The most serious threat comes from black sigatoka, a fungus that has spread around the world since devastating plantains in Fiji during the '60s.
Other blights are Panama disease, a soil fungus impervious to fungicides, and weevil borers, a pincer-tipped bug with larvae that gouge burrows into stalks.
We westerners love bananas, but we won't go hungry if they disappear. They taste good in daiquiris and smashed into a baby's mush. The most profitable export fruit in the world, bananas earn $12 billion for Chiquita, Dole and other companies growing crops in South America and Africa.
For the poor in developing nations, however -- more than 400 million people, from Honduras and Cuba to Uganda, Ethiopia and the Philippines -- the banana and plantain are major food staples. They consume 9 of 10 bananas and plantains, 90 million metric tons annually.

In the 1950s, Panama disease struck and obliterated the Gros Michel, which was replaced by the Panama-disease-resistant Cavendish, the slightly less sweet banana that now appears on our grocery shelves.
Exporters are able to fend off pests by a heavy use of chemicals -- as many as 40 sprayings a year, more than any other crop -- which poor farmers cannot afford. Field hands working in Latin America suffer from high rates of leukemia and sterility from these pesticides.
