Zoos are among mankind's oldest institutions, dating
back at least 4,500 years, and probably more. Across the world they have brought
together and displayed live wild animals for people to look at and over the
years {{B}}{{U}}hundreds of millions{{/B}}{{/U}} have. Any institution with so long a
history and so universally attended must reach something in people deeper than
idle curiosity. Since it is fashionable to speak of roots today, it might be
suggested that zoos allow us to stay in touch with our most primitive roots in a
primeval world where human survival depended on knowing the shapes and habits of
wild animals. So important were wild creatures to our distant ancestors that
they were the most frequent subjects of paintings on cave walls, formed the
basis for virtually all early religions, and were in numerous instances
worshipped as gods. Now our survival is threatened more by what
we ourselves have worked, and by the stresses of living among these creations,
than it is by wild animals to whom we relegate less and less living space with
each passing year. In this world the need for good zoological gardens is urgent.
The exponential growth of human population and the ever-increasing sprawl of
cities does more than rob land from wildlife: it pushes the animals farther away
from city dwellers. People live in brick, concrete, and glass environments where
they lose all touch with wilderness; children grow up who have never tried to
catch a frog, never seen a hawk soar or a deer step daintily into a forest
clearing--let alone watched a herd of elephants ambles across the river or a
pride of lions stalk prey. People who have the time and money
can take an occasional trip to the remaining wilderness and find, in places
where wild animals still live, the renewal of spirit that comes from prolonged
visits to wild country. For millions of others who are unable to leave the
cities or can't afford to, good zoos laid out among plants and trees can bring
what conservationist Lan Player calls "a taste of wilderness". Perhaps more
important in the long run, zoos can help give deprived people an awareness that
we share the world with many other animals and should have a decent regard for
their worth and right to live. If zoos did no more than accomplish these two
ends, they would serve a noble purpose. As it happens, however,
today's zoos can do far more. They can become breeding centers for those wild
species whose continued existence has become precarious. The term "captive
breeding" has been used to describe this new role of zoos, and this book
describes the effort--the most important task that zoos have yet
undertaken.
