The human brain is plastic in development and in responses to life experiences. Long periods of starvation or abuse imprint long lasting changes on relationship strategies and fears, they change brain structure and function, the ways we see the world, generally to less trusting attitudes. The ways we see the world make the behaviours that again imprint on others in future relationships. The current overshoot of human populations for biosphere carrying capacity, ensures dominator society stresses for a majority. 1 in 6 children now starving in a war zone. Resource poor crowded cities add future stresses until human self extinction or mass population collapse, which ever comes first.
