the conversion of agricultural land to urban or other uses. Once an acre of prime
corn-belt land is covered by concrete or asphalt, it is, to say the least, hard to grow
corn there (Figure 1-2).
Urban expansion, industrialization, highway construction, and other alternative uses for our land surface are becoming increasingly important. This is not
necessarily bad. Land is an important natural resource for many purposes-food
and fiber production is only one purpose. Unfortunately, this expansion tends too
often to occur on our best land for farm production. Land-use planning is more
important now than ever. We must, as a nation, establish our priorities for land
use. We must then allocate our land and soil resources based on those priorities.
It would seem that, with the world population explosion, food production must
rank very high in those priorities. Nevertheless, manufacture of other products,
transportation, processing, and distribution are also critical to our way of life.
Managing our soil and land resources is a complex problem. Hard decisions
need to be made, both now and in the future.

Water reSOUrCeS
"Water, water, everywhere" was the wail of the old sailor in The Rime of the Ancient
Mariner by Samuel Taylor Coleridge. Indeed, this resource is abundant. Why
worry about managing our water resources when 70 percent of the earth's surface
is covered by it?
However, the ancient mariner continued his lament with, "nor any drop to
drink." There is a great difference between water and usable water. Remember
our definition of natural resource: Water is a natural resource only when it can
be put to use by humans. The oceans provide us with marine products and a
medium in which ships can travel. They contain minerals and metals, and tide
flows can be harnessed for electrical generation. The ocean floors contain vast
deposits of oil and minerals (Figure 1-3).
