The population of the world is now over 4 billion, with approximately two-thirds of this population being in regions characterized as being underdeveloped. Today there are 200,000 more people than there were yesterday, with about 10,000 persons estimated as dying each week from lack of food. By the year 2000, it is estimated that 6 to 7 billion persons will live in the world. Current global surveys measuring food supply per person indicate severe undernutrition (too few calories) and an unbalanced diet (too little protein). The most critical single shortage in the world food supply is protein, vital to the human diet. Many nations cannot produce or import enough for their minimum needs. Others face serious shortages and prohibitive costs. Today, millions suffer protein malnutrition. Tomorrow, as populations continue to rise, the problem will grow far worse unless new protein sources emerge. Single cell protein (SCP) is a new food source that will help alleviate this protein deficiency.
