1) We need to preserve genetic diversity of staple crops to avoid the well known risks of monoculture (adapted pests, systems fragility, etc.). This can probably be done within the GMO paradigm.

2) Industrial agriculture cannot become an excuse for poor sanitation at any point in the food supply, as it has done in the USA such as with hog farming. Sanitation + vaccination = civilization, and the reverse is also true;-)

3) It’s well known that organisms multiply up to the limit of their food supply. This is true for the vast majority of species including humans. Therefore any effort to expand the food supply must necessarily be accompanied by efforts to reduce human population to a sustainable level and keep it there. The biggest breakthrough we need in this area is a reliable male birth control pill.

4) Human birth rate comes down to a sustainable number voluntarily, when three conditions are met:
a) Female equality.
b) Basic economic security.
c) Availability of birth control.
These conditions have to be enforced worldwide such as via international trade agreements. We have no choice in this matter. The longer we wait, the fewer the options remain, and those that remain become increasingly ugly.

5) Failure to address population issues relative to food supply will only result in another wave of failure and resumption of hunger and the conflict it engenders. If the food supply has been expanded using high-tech methods, a resumption of hunger will also tend to produce an increased level of cynicism about science and technology: exactly what the world does not need when it comes to dealing with the other consequences of climate change.

?kämp??tiSH(?)n/
noun
Sociology. Rivalry between two or more persons or groups for an object desired in common, usually resulting in a victor and a loser but not necessarily involving the destruction of the latter.

Funny thing about having too many people around… They tend to want to eat. Eat the food you’re wanting to eat, that is.

Which is a problem when the climate is reducing the amount of food that’s being produced.

This tends to result in… Wait for it… Competition for food. Which can, and sometimes does, result in one group driving out and… Wait for it… shooting members of the other group.
