Right, and what's the problem there? The old type of banana that was popular got wiped out, and we adapted. The current popular type is, IIRC, slowly getting wiped out as we speak. That sucks, but we'll adapt again. As long as the plants/seeds for other varieties exist somewhere, we'll find a way to adapt.

Heck, if anything, we're probably more flexible now since it's now possible to directly genetically engineer new varieties and we have massive seedbanks around with modern infrastructure for distribution.

> Not in markets, because a hundred years ago most people didn't get their produce from a market. They got it from their own gardens or the local farm.

For people in rural areas, sure, but in more urban areas I'm sure they had markets of some sort.
