the situation worse, there is as yet no sign that any slowing of the world's popula-
tion is in sight. Although the birth-rate has dropped in some nations, including the United
States , the population of the world seems sure to pass six billion and perhaps even seven billion as
the twenty-first century opens.
(73) The food supply will not increase nearly enoueh to match this, which means that we
are heading into a crisis in the matter of producing and marketing food.
Taking all this into account , what might we reasonably estimate supermarkets to be like in
the year 2001?
To begin with, the world food supply is going to become steadily tighter over the next thirty
years-even here in the United States. By 2001 , the population of the United States will be at
least two hundred fifty million and possibly two hundred seventy million, and the nation will find
it difficult to expand food production to fill the additional mouths. (74) This will be particularly
true since energy pinch will make it difficult to continue agriculture in the high-energy American
fashion that makes it possible to combine few farmers with high yields.
It seems almost certain that by 200l the United States will no longer be a great food-export-
ing nation and that , if necessity forces exports, it will be at the price of belt-tightening at home.
In fact, as food items will tend to decline in quality and decrease in variety, there is very
likely to be increasing use of flavouring additives. (75 ) Until such time as mankind has the sense
to lower its pupulation to the point where the planet can provide a comfortable support for all,
people will have to accept more "unnatural food" .
