Fertility Rates: Empirical View

The data show the world's population balance (births vs. deaths) is stabilizing. Leads to thoughts that non-growing populations along with technological advances could possibly enable humans to reduce conflicts (including warfare) that have frequently arisen re: access to resources. If there's enough food, energy, etc., for everyone, seems hardly anything to fight over.
OTOH could be argued that people like contention, even seek it out no matter how minor the matter. However, not adding to population pressures might at least help us avoid the more destructive forms of contention, that itself would be a positive.
