At the end of the first week, the rich man checked to see how much he owed and was pleased to find that the total was only $1.27. By the end of the second week he owed only $163.83. On the twenty-first day, however, the rich man was surprised to find that the total had grown to $20,971.51. When the twenty-eighth day arrived the rich man was shocked to discover that he owed $1,342,177.28 for that day alone and that the total reward had jumped to $2,684,354.56! This is precisely what alarms the New Malthusians. They claim that humanity has entered the “fourth week” of an exponential growth curve. To see why they think the day of reckoning is just around the corner, look at Figure 20.2 . It took from the beginning of time until 1800 for the world’s population to reach its first billion. To add the second billion, it took only 130 years (1930). Just 30 years later (1960), the world population hit 3 billion. The time it took to reach the fourth billion was cut in half, to only 15 years (1975). Then just 12 years later (in 1987) the total reached 5 billion, in another 12 years it hit 6 billion (in 1999), and in yet another 12 years it hit 7 billion (in 2011).

The world’s population growth is astounding. Consider this: At each sunset, the world has 246,000 more people than it did the day before. Each year, the world’s population increases by about 90 million people. During the next 4 years, the world will add more people than there are in the entire United States. In the next dozen years, the world will add as many people as it did during the entire time from when the first humans began to walk the earth until the year 1800. These totals terrify the New Malthusians. They are convinced that we are headed toward a showdown between population and food. It is obvious that we will run out of
food if we don’t curtail population growth. Soon our television screens will be filled with images of pitiful, starving children. The Anti-Malthusians All of this seems obvious, and no one wants to live shoulder-to-shoulder and fight for scraps. How, then, can anyone argue with the New Malthusians? To find out, let’s turn to a much more optimistic group of demographers, whom we can call the Anti-Malthusians . For them, the future is painted in much brighter colors. They believe that Europe’s demographic transition provides a more accurate picture of the future. This transition is diagrammed in Figure 20.3 . During most of its history, Europe was in Stage 1. Europe’s population remained about the same from year to year, because its high death rates offset its high birth rates. Then came Stage 2, the “population explosion” that so upset Malthus. Europe’s population surged because birth rates remained high while death rates went down. Finally, Europe made the transition to Stage 3: The population stabilized as people brought their birth rates into line with their lower death rates.
This, say the Anti-Malthusians, will also happen in the Least Industrialized Nations.
