THE BIG PROBLEMS–PART 1
As we wobble toward the 21st century, there can be little doubt
that repairing the environment will require effort and sacrifice
from nearly everyone.
The work to be done is substantial. To celebrate earth day this
year, William K. Stevens of the NEW YORK TIMES put together a
summary overview of our situation. [1] Mr. Stevens tried to be
optimistic. He pointed out that industry and the U.S.
Environmental Protection Agency (EPA) say that the annual release
of toxic chemicals has been reduced 43% in the past seven years
even as the yearly manufacture of toxic chemicals increased 37%
during the same period. [2] (EPA has no staff assigned to
checking the accuracy of the “toxics release inventory” [TRI]
data that industry reports to EPA each year, so everyone has to
accept industry’s 43% claim at face value. Furthermore, these
figures make us ask, where are the increased quantities of toxic
chemicals going if they are no longer being released directly
into air and water? Do they perhaps wind up in products that
eventually go down the drain or into the local dump?)
In any case, there is definite cause for celebration of some big
accomplishments over the past decade or two. Many incinerators
have been successfully opposed; many filthy dumps have been
closed; within the U.S., nuclear power has not experienced the
growth once predicted for it (though overseas is another story);
the air in many cities is cleaner than it used to be; the flow of
sewage and industrial waste into rivers and streams has been
substantially reduced.
But even as Mr. Stevens was trying to maintain an optimistic
spin, bits of gloom crept into his text: Two out of every 5
Americans still live in areas where the air is unhealthful (and,
though Mr. Stevens did not say so, those affected are
disproportionately people of color). Forty percent of the
nation’s rivers and lakes are not fit for drinking, fishing or
swimming. Last year, EPA issued more than 1000 warnings against
eating fish in chemically-contaminated waters. (And many states
issued their own warnings, in addition.)
Mr. Stevens went on: Despite reductions in sewage and industrial
waste reaching waterways, “…scientists say that biological
quality [of rivers and streams] has continued to decline anyway
because of farm and urban runoff, destruction of streamside
vegetation, erosion, introduction of exotic species,
straightening of streams, and building of dams.” (In other
words, the direct and indirect effects of what we traditionally
call “development.”)
“People commonly equate environmental protection with conquering
chemical pollution,” Mr. Stevens wrote. ‘They say we’ve put a lot
of time and resources into reducing pollution and everything’s
O.K.,’ said Dr. James R. Karr, an aquatic ecologist who heads the
University of Washington Institute for Environmental Studies in
Seattle. But when the actual state of aquatic biology is added
to the assessment equation, he said, it ‘doubles the proportion
of waters that are in violation of water quality standards.’ In
other words, he said, ‘the situation is not getting better.’”
Mr. Stevens went on: “As a result, freshwater fish and
invertebrates face particularly serious perils, and 362 species
of freshwater fishes have been extinguished or are endangered as
a result of human activity, said a broad group of scientists who
met at the American Museum of Natural History in New York City
recently to assess the dangers to biological diversity,” Mr.
Stevens wrote.
“The fate of the American landscape and waters and the creatures
who live there is perhaps the biggest domestic environmental
problem on which the nation is not yet getting a good grip, a
number of experts say,” according to Mr. Stevens.
Mr. Stevens then describes a recent report titled ENDANGERED
ECOSYSTEMS OF THE UNITED STATES: A PRELIMINARY ASSESSMENT OF LOSS
AND DEGRADATION, available from the National Biological Service
(NBS), a research organization within the federal Department of
Interior. We obtained the report over the Internet, [3]and its
conclusions are stunning:
** 81 percent of the nation’s fish communities have been harmed
by human actions, while 98 percent of the streams in the lower 48
states are degraded to the point they can’t qualify as wild or
scenic rivers.
** 90 percent of its ancient or “old-growth” forests have been
lost.
** 95-98 percent of the virgin forests in the lower 48 states had
been destroyed by 1990; 99 percent of the virgin Eastern
deciduous forests have been eliminated.
** In the Northeast, 97 percent of Connecticut’s coastline is
developed; 95 percent of Maryland’s natural barrier island
beaches are gone; and almost all of Ohio’s bottomland hardwood
forests are gone.
** In the South, 99.99 percent of Kentucky’s native prairies have
disappeared; 98 percent of the Southeast coastal plain’s longleaf
pine forests are gone; and 88 percent of southwest Florida’s
slash pine forests have been eliminated.
** In the Midwest and Great Plains, 90 percent of the tallgrass
prairie has disappeared, as has virtually all of the prairie in
Michigan and Ohio, 72 percent of Minnesota’s northern hardwood
forests, and 86 percent of Minnesota’s red and white pine forests.
** In the West, 99 percent of California’s native grassland is
gone, as are up to 90 percent of western Montana’s old growth
forests and low-elevation grasslands; half of Colorado’s wetlands
and 90 percent of Hawaii’s dry forests and grasslands are gone. [4]
The NBS report was prepared by Reed Noss of the University of
Idaho’s Department of Fish and Wildlife, the late Edward LaRoe
III of NBS, and J. Michael Scott, working with NBS’s Idaho
Cooperative Fish and Wildlife Research Unit at the University of
Idaho.
An ecosystem is a community of species in a specific area. An
ecosystem can range from a very large territory defined by
specialized plants, such as hardwood forests or sagebrush, to a
much smaller area defined by varied plant and animal life, such
as a fen or wetland.
“Loss of biodiversity is real,” the authors said, adding that the
general public is aware of damage to tropical forests but less
familiar with losses of woodlands, swamps, and grasslands.
Regionally, 58 of the troubled environments were in the
Southeast, 37 were in the Northeast, 23 in the Midwest and Great
Plains, 11 in the Northern Rockies, 10 in the Southwest, 17 in
California, and two in Hawaii. “The extent to which various
ecosystems have declined in the United States –despite
uncertainties and unevenness in the data –portrays a striking
picture of endangerment,” the NBS report says.
“Our results indicate that more biodiversity has been lost than
is generally recognized in environmental-policy debates. A
continually expanding list of endangered species seems inevitable
unless trends of habitat destruction are reversed soon through a
national commitment to ecosystem protection and restoration,” the
report says.
Rutgers University biology professor David Ehrenfeld has a
different take on it. A national commitment to ecosystem
protection will be necessary, he says, but not sufficient. “The
ultimate success of our efforts to stop ruining nature will
depend on a revision of the way we use the world in our everyday
living when we are not thinking about conservation. If we have
to conserve the earth in spite of ourselves, we will not be able
to do it,” he says. [5] The destructive changing of nature
ceases, he says, “when people who are not actively trying to save
the world play and work in a way that is compatible with the
existence of the other native species of the region. When that
happens–and it happens more than we may think –the presence of
people and the changes they bring may enhance the species
richness of the area, rather than exert the negative effect that
is more familiar to us,” he says.
An alternative, Mr. Ehrenfeld says, “is a transformation of the
dream of progress from one of overweening hubris, love of
quantity and consumption, waste, and the idiot’s goal of
perpetual growth to one of honesty, resilience, appreciation of
beauty and scale, and stability –based in part on the inventive
imitation of nature. We have already had examples of what this
alternative can be like: the CHINAMPAS, or swamp gardens, that
were the glory of pre-Columbian Mexican farming and which might
again sustain the Mexican people; the city of Florence in the
Renaissance and the city of Toronto before the building boom of
the 1970s and 1980s; the hedgerows of post-Elizabethan England;
old Jerusalem and the terraces of the Judean hills; and the
ingenious multicrop gardens of tropical west Africa, to name a
few. The changes that people inevitably work on the earth do not
have to be destructive ones.” [5]
“If this alternative way of living grows and prospers, I doubt
that it will do so by some master plan or protocol,” Mr.
Ehrenfeld says. “Instead, it will be advanced by countless people
working separately and in small groups, sharing only a common
dream of life. They will tend to be flexible, inventive, and
pragmatic, and most will have practical skills–carpentry, the
building of windmills and small bridges, the design and repair of
engines and computers, the recognition and care of soils, the
ability to teach…. They will devote their first energies to the
places where they live. They will come to authority not by
violence but by their evident ability to replace a crumbling
system with something better. And they will share an awe for a
power nobler and larger than themselves, be it God, nature, or
human history.” [5]

[2] Mr. Stevens gives the 43% figure; we calculated the 37%
figure from data on U.S. synthetic organic chemical production,
1967-1988, appearing in Table 77 of Appendix E in the President’s
Council on Environmental Quality’s report, ENVIRONMENTAL QUALITY
1970-1990 (Washington, D.C.: President’s Council on Environmental
Quality, 1991); during 1967-1988, annual U.S. chemical production
increased at the rate of 4.5% per year. If that growth rate held
during the last 7 years (probably a good assumption), those years
saw a 37% increase in annual output. For a primer on such
calculations, see RHWN #197 and #199.
