No, seriously. There is no food crisis. As a species we have a food distribution problem, and a food wastage problem and they're rather shocking at that, but we really have no issue with feeding the population of earth today without resorting to eating genetically modified photosynthetic aphids.
Now, a long term lack of motor fuel, is a problem, but aphids don't really solve that either.
Mind you, this is scientifically interesting, but there really is no need to tie every technically interesting scientific discovery to the end of the world. Believe it or not, some of us like science for science's own sake.
