The collapse of all plant life would mean the death of humans. Nuclear winter is a well-studied and modeled phenomenon.

  I don't think we would collapse all plant life. While we have the theoretical capability to destroy all plant life, I think realistically we'd end up obliterating a few cities before war would cease, and a full-on nuclear winter is unlikely.

    You don’t need to kill all plants, just enough of those we can eat. Not even all of those, either. Look into history to see what happens when enough people don’t have enough to eat.
