There's room for improvement on the consumption end, too, as 30 percent of food never makes it into a human stomach; in the developed world, we let produce slowly rot in the backs of our fridges...
This actually got me thinking. As I'm sure many of you have experienced often, buying things and stuff them in the fridge only to find it as the source of that barf smell in the fridge, rotten and oozing stuff. Instead of making bigger (deeper) fridges, why not make fridges w i d e r ?
With wider and shallower (around 1 foot deep) fridges -- with perhaps 3 to 4 doors, lined up sideways, preferrably at eye level -- foodstuff can be stored at a maximum two or three deep, making it easier to see and reach.
I know it will take up space width-wise, but it will save in terms of depth. More doors than regular fridges are needed ,so that less cooling energy is wasted when door is opened. One can have a section for drinks, and others for vegetables & fruits, packaged foods, etc.
I also know it's not for everyone, apartment dwellers might not have enough space for this. But with the right marketing strategy, this may appeal to many middle-class families and McMansioners. With money saved with much more food actually eaten than being let to rot, the thing practically pays for itself!! [cue infomercial jingle]
