Eh, cucumbers for example having that plastic survive a lot longer which reduces waste (and makes logistics lighter which saves resources) which comes out as net benefit compared to what it takes to package them like that. I used to think the plastic was dumb but was surprised when I looked into it.

Not sure what's the cost/benefit with avocados, it's probably different with every veggie. And now that I think about it, might depend on local situation. The source I read was Finnish.
