Population Growth and Food Supply: The Real Energy Crisis Pre-reading Activity Discussion Questions How fast is the world population growing? Do you think there are already too many people in the world? How fast is the population of the UAE growing? What are some of the problems associated with a large population? What are some of the ways we can tackle these problems? What do you think is the ideal family size? To find the population of any country click here, select the country in the drop-down menu, and choose the category people. http://www.cia.gov/cia/publications/factbook/geos/in.html 1 of 7

Population Growth and Food Supply: The Real Energy Crisis (1) How does it feel to be constantly hungry? If you are among the affluent one-third of humanity which consumes two-thirds of the world's total food supply then you have no concept whatsoever of the real meaning of hunger. But the majority of people on earth spend most of their waking hours and 60-95% of their incomes just trying to get enough food for themselves and their children to prevent starvation and debilitating diseases. (2) With an impressive sequence of agricultural revolutions, we have increased our food growing capacity several hundredfold. In the United States, Australia and Canada, countries that have traditionally grown a lot of food, the rural population is below 5 percent. In some European countries it is below 1 percent. (3) There are a number of reasons for the vastly increased yields in western countries since the First World War. The most important of these are: a. The widespread availability of relatively inexpensive fertilisers. b. Mechanised agriculture powered by energy, from fossil fuels and to some extent nuclear power. c. The development of an impressive array of chemicals - herbicides, fungicides and insecticides - to reduce crop losses through the activities of pests. d. Intensive research into plant breeding and stock improvement. e. Improvements in the storage, processing, distribution and marketing of food. (4) There is also another fundamental paradox in these impressive feats. Although we are feeding more people than at any time in history, there are also more hungry and malnourished people than in any previous time. This is the real energy crisis in the world today. It affects the health and survival of one-third to one-half of all human beings. Total production has increased since 1961 on all continents except Africa, yet the per capita food production in the less developed countries is not different from the inadequate levels that existed in the early 1960's. (5) Despite massive efforts in certain problem areas, world and regional food production has barely kept up with population growth. Are some regions in the world doomed to massive famines in the coming decades? There is no easy answer to this controversial question. Some people point out that we are already experiencing the greatest famine in the history of humanity with somewhere between 5 and 20 million human beings dying of starvation, malnutrition and diseases associated with malnutrition each year. (6) In one sense there might be no global shortage of food if the total quantity of calorie available were distributed on a per capita basis. However, the world food problem is not just the quantity but also the quality of food available, the uneven food distribution and buying power, and the ecological side effects of modern agriculture. Many suggestions have been made for dealing with the food crisis, but before evaluating these proposed solutions we must see how the laws of thermodynamics as always, determine the limits of what we can and can not do.
