I wasn’t suggesting a leaf feels pain or that it would be the leaf that would have some definition of pain and suffering if it were ripped from the stem. It would be the rest of the plant.
So why are you bringing up a part that, when separated from the whole, no longer has that capacity in any living thing?
Dude… all I can say is that if two massive trees fall down right outside your house in the middle of a bunch of high wind and lightning and thunder and hail and torrential rain and are anything less than terrified, you are a hell of a lot braver than I am.
