Precarious world food situation.

With the disappearance of the food grain reserves the whole world food situation is precarious. Cereal grains provide a good indication of total food production. There are according to the author 2 choices in bettering the food situation: 1) increase the land area under cultivation and/or 2) increase the yields on the area already under cultivation. The only way to restore productivity to the soil is through research and fertilizer is a must for most of the depleted soil of the developing world. However it is in very short supply. Much research must be done locally. Fertilizer production must be expanded. The population situation should be considered together with the food situation.
