According to the very information given out by the Food and Agriculture Organization and the UN Fund for Population, whose actions to control demography are well known, there is actually enough food to feed the planet. The problem is neither demographic nor agronomic; it is moral, political and organizational in nature.
That doesn't prevent some alarmist agronomists and demographers from advocating "permits to procreate", as they exist in China. When one observes that this idea was already proposed by Hitler in "Mein Kampf", there are some people who get furious. Yet that is the truth, and it would be appropriate to draw the right conclusions
