Ending the global hunger crisis would help end wars, so ending hunger
should come first. Nations with enough food to feed their people, and
especially nations with surplus food to sell abroad, are less likely to be
aggressive troublemakers on the world stage. Well-fed people are more
satisfied with life, naturally, and less likely to pick quarrels. Systematic
attacks on hunger would give developed nations more peace and security,
as well as increasing their popularity around the world.
It's a known fact that we as humans are reaching an environmentally unsustainable population level. Solving the global hunger crisis simply cannot be done, as we will simply keep growing in number and eventually annihilate ourselves by using up all necessary resources. Thus, the hunger crisis is simply a means of population control which is very necessary for humanity.
