The great Chinese famine is still discussed nowadays, and what were the actual causes for it. It seems that the strict and not very well thought through policies of the government in that period was the main cause because the planing was terrible, measures for protection of the crops were on a minimum, the amounts of certain product were projected for perfect conditions so any little disturbance would immediately cause a problem with starvation. The government blamed it all on the weather conditions, but it was just cover their terrible policies in the agricultural department. The starvation was so terrible that around 30 million people died and 30 million births were postponed.
