Abstract
A population policy, that assures the negative freedom of the individuals who are not forced to proceed on abortion, their well-being and their positive freedom of escaping from preventable mortality, of avoiding mortality during infancy and childhood, of being free from hunger and undernutrition, is possible in developing countries, if the developed states should realize that they overconsume and that they use nature as their own resource, at the expense of the rest of the world.By avoiding rich nations' overconsumption and injustice towards the poor ones we are moving towards a restraint on resource depletion, environmental degradation, poverty and population explosion, on the destruction of a sustainable life in general.
