U n i t i Introduction

P

eople have always lived in an environment. Our environment
consists of everything around us: soil, water, plants, animals,
energy, minerals, atmosphere, sunlight, and more. Our environment has provided everything for our survival. If any part of our
requirements had not been met, then humans would not exist. at one
time, our natural resources could be used without regard for the future.
there were fewer people, and our technology did not allow for rapid
and massive use of natural resources. trees were cut by stone axes,
then later by metal saws and axes, and coal was harvested by hand.
those days are gone now.
People still live in a finite environment, but now we have the ability to use
our resources on unbelievably large scales. We can take water from an aquifer
hundreds or even thousands of feet underground, and with the aid of modern
technology we can quickly level mountains, change the flow of rivers, and take
energy from the atom. All of that sounds impressive but, taken together, our
advancing technology and our growing population present a problem. We find
that we must, in the future, live in the same environment-our "spaceship earth."
And it is not getting appreciably larger. We know now that many of nature's
resources are not going to last forever.
Wise use of our natural resources is not a new idea; but today, more than ever,
it must become a common goal. Managing our natural resources for the future
as well as the present must become a priority for all of us. This chapter explains
a number of important ideas in natural resources conservation and management.

tHE nAtURE OF RESOURCES
In a very real sense, everything in our environment could be considered a
natural resource. Rocks can be used as gravel for our roads, facings for our
buildings, or material for our statues. Wind, falling water, still air, resting
water, minerals, insects-virtually everything around us can be considered
a potential resource. When someone takes an object and uses it to perform
work or change other parts of the environment, that object has become a
resource. Even before its use, the potential for use makes the object a natural
resource.
Those things that have become, or show promise of becoming, important to
us are the natural resources we are concerned about in this book. Those natural
resources may take many forms. More importantly, some resources are capable of
going on forever. On the other hand, others are very limited. They may be usable
over and over, or they may be gone forever with a single use. Let's look at both of
these categories a little closer.

nonexhaustible Resources
Natural resources that can last forever regardless of human activities are
nonexhaustible. They renew themselves continuously. This does not mean that
such resources are not limited-they very well might be available in limited quantities at any given time. It also does not mean that human misuse cannot damage
such resources-it certainly can.
A good example of a nonexhaustible resource is surface water. If you take a
gallon of water from a river, another gallon will replace it from rain. If you dam
a stream, the water will simply go elsewhere. If we damage a watershed so that
its rainfall does not soak into the ground, the rainfall will simply go elsewhere.
