There is a very high risk of famine[1] and there is already an extreme food shortage. If the Israelis don't allow more food to enter and open more borders/allow see access a famine is guaranteed. The UN resolution that passed yesterday should prevent that but we have to wait and see if Israel accepts it. IMO starving a population is a genocide.
