Managing Our Natural Resources, 6e, Camp - 3

Chapter 1

I

n earlier times, people did not have the technology to see beyond
the horizon. as a result, distant places were more mysterious to people than they are today and many feared to go beyond the boundaries of the land that they knew. the apparently limitless nature of the
world led people to believe that our natural resources were endless,
boundless, and inexhaustible. in reality, when there were fewer people
and when our technology was limited to human and animal power, we
had very limited ability to use the natural resources that were available.
When our technology did not allow us to change the face of the earth
so dramatically, nature actually did provide resources almost beyond
the capacity of humans to use them. But now our machines allow one
person to do things that armies of workers could not in ancient times.
More importantly, the world population of humans has surged in the past
couple of centuries. According to the U.S. Census Bureau, the human population
first reached 1 billion in 1804. Reaching the first billion mark took many thousands of years of human history. A total population of two billion was reached in
1927. That second billion took only 127 years. According to the United Nations,
the world's population exceeded 6 billion on about October 12, 1999. That figure
was estimated at just over 7.1 billion on November 30, 2013-just 14 years after
the 6 billion mark was reached. According to United Nations estimates, the world
population should exceed 8 billion by 2025 and then grow more slowly to about
9 billion by 2100 and begin to level after that. See Chapter 3 for a more detailed
discussion on human population. Everything has changed in the past couple of
centuries. Yet, many people continue to treat nature's gifts as endless, boundless, and
inexhaustible. This cannot continue. It is to help you appreciate that dilemma that
this book was written.

Special Features to Look for in This Book
To guide you along the learning path, each chapter begins with a list
of objectives and terms to know and ends with review questions,
discussion questions, and suggested activities. Each unit ends with a
Case Study intended to help you dig deeper into some part of the unit.
The Appendices also can be very helpful:
Appendix A provides links to authoritative web sites.
Appendix B describes Hunter Safety, Boating Safety, and other
safety programs.
Appendix C outlines a safety program for school laboratories and
SAE work sites.
Appendix D offers ideas for Supervised Agricultural Experience
(SAE) Programs.
Appendix E includes several additional case studies.

What IS a NatUraL reSOUrCe?
One authority defines a natural resource as any form of energy that can be used
by humans. Others would tell us that natural resources are objects people use. In
an ecological sense, anything that was not produced by humans and that is or can
be useful in our lives is a natural resource.
