Last week I took part in some gleaning action (actually authorized by the farmer).
The harvesting machinery was still in the field so we got to look how it works.
The machine that first passes chops off the tops, and the next machine pulls them out the ground.
... but it chops off quite a lot off the top that is discarded in the field.
The photo attached shows the worst case I found, others were less bad, but overall a huge amount of edible carrot was still attached to the green bit.
Sunbeam City is a anticapitalist, antifascist solarpunk instance that is run collectively.
