Biodiversity: The Spice of Life
 In
its basic form, biodiversity refers to the variety of native plants, animals,
and other living organisms that inhabit the earth. Some people like to think
of biodiversity as another word for nature.
The variety of life on earth is incredible. There may be as many
as 30 million total species, yet scientists have discovered fewer than 2
million so far. Individual animals within any one of these species may have
different sizes, colors, and behaviors. A wide diversity of species share an environment and interact with each other in an
ecosystem. Finally, the landscape of each continent on earth is a patchwork
quilt of unique ecosystems that run together and overlap. All
of these factors contribute to the earth’s biodiversity—the variety of life.
Why is Conserving Biodiversity Important?
“The first rule of intelligent tinkering
is to save all the parts.”* Anyone who has taken something apart and then
tried to reassemble it knows this t o be true. If a part is lost, the machine will not work very
well—if it works at all. And as mechanisms become more complex, the
individual parts generally become more and more critical.
If
this is true for machines—if a missing cog or belt can render a car’s engine
useless—how much more might a missing organism affect the health of an
ecosystem whose complexity is overwhelming?
Conservation of
the earth’s biodiversity must be a primary concern for all people, for when
biodiversity is destroyed—at any of its levels—”tune-ups” and “replacement
parts” are not available.

Almanac, (Oxford
University Press, 1966).
