China's One Child Policy should be enforced and implemented as a universal law. The world's population is too high, depopulation and population control are needed. Resources are running out. Now resources can last longer if populations are reduced or controlled.
Hard line Green environmental policies could help achieve depopulation and control the world's human population. Humans are destructive and they destroy the environment in order to increase economic growth. Economic growth is built around exponentially human population growth consuming resources. Most of the resources are limited and once they are gone, that is it.
What will happen when all the resources run out? Measures like China's One Child Policy help slow down the exponential human population growth.
