> shelf lives are massively extended. I think this would be a good thing.
50 years ago many fruits and vegetables had a lot shorter shelf life, however that has been greatly extended due to selected breeding. For example tomatoes used to have a shelf life of around 3 days, but now it's 3 weeks or more.
The disadvantage of this is that now there are a few varieties that dominate what you can buy in supermarkets, and they are optimized for economic features. This means other features like taste and nutrient content are a lot worse than it was 50 years ago.
