Floods, fires, volcanic eruptions, earthquakes, hurricanes--we
are quick to call them ''natural disasters.'' But are they? Did the
great fires that swept Yellowstone in 1988 devastate the park, or
did they just ravage our image of the park as a fixed, unchanging
national treasure? This lucid, lively book reveals the
shortsightedness behind conceiving of such events as disastrous to
nature. Indeed, Seth Reice contends, such thinking has led to
policies that have done the environment more harm than good--the
U.S. Forest Service's campaign against natural forest fires and the
Army Corps of Engineers' flood prevention program are examples. He
points out ways in which we can better address the wide range of
environmental problems humanity faces at the dawn of the new
millennium.
Reice argues, in terms refreshingly nontechnical yet
scientifically sound, that the traditional, equilibrium
paradigm--according to which ''stability'' produces healthier
ecosystems than does sudden, sweeping change--is fundamentally
flawed. He describes a radically different model of how nature
operates, one that many ecologists and population biologists have
come to understand in recent years: a concept founded on the
premise that disturbances help create and maintain the biodiversity
that benefits both the ecosystem and ourselves. Reice demonstrates
that ecosystems need disturbances to accomplish indispensable tasks
such as the production of clean air and water. He recommends
changes in environmental management to incorporate the essential
role of natural disturbances.
This book shows that every tornado's funnel cloud, every forest
fire's billowing cloud of smoke, has tremendous benefits for the
ecosystem it impacts. As anyone concerned with man's impact on the
environment will appreciate, this is the cloud's real silver
lining.
