FORESTS
AND BIODIVERSITY
The
number of plant and animal
species inhabiting the
planet is not accurately
known. Nearly 2
million
species have been
identified, but estimates of
the number yet to be
described range
from
10 million to 30 million (United
Nations Environment Program,
1995). Ecosystems of all
kinds
are under pressure
worldwide. Coastal and lowland areas,
wetlands, native grasslands,
and
many types of forests and
woodlands have been
particularly affected or destroyed.
While
forests
decreased by about 5 per cent
between 1980 and 1995, the rate of
deforestation has
been
declining
slightly (Food and Agriculture
Organization of the United
Nations, 2000b).
Additional
threats confront fragile
aquatic habitats, including
coral reefs and freshwater
habitats,
which face an array of assaults
from dams to land-based pollution to
destructive
fishing
techniques.
Over
the past 150 years, deforestation
has contributed one third of
the atmospheric build-up
of
CO2, and it is a
significant factor in the loss of
species and critical ecosystem
services
(Intergovernmental
Panel on Climate Change, 2000). Since the
beginnings of agriculture
10,000
years ago, by some estimates, almost
half of the earth's forests
have been converted
to
farms,
pastures and other uses, and
only one fifth of original
forest remains in large,
relatively
natural
ecosystems. Forested areas, including
forest plantations as well as
natural forests,
occupied
about one fourth of the
world's land area in 1995.
Tropical rain forests are
important
for
the quantity and diversity of
life they support. They
cover only 7 per cent of the
earth's land
area,
but contain at least 50 per cent of
terrestrial species (Food and
Agriculture Organization
of
the United Nations, 1999b).
The influences of forests and
biodiversity are global,
reaching
far
beyond national borders, in both
space and time. Therefore,
international cooperation is
essential
in order to integrate environmental
issues better into global,
regional and national
decision-making
processes.
Ozone
depletion is also a serious concern.
Caused by the release of
CFCs into the
atmosphere,
ozone
depletion may lead to several
hundred thousand new cases
of skin cancer each year
and
destroy
many valuable food crops.
Also, ocean plankton, on
which the entire ocean's
food chain
depends,
may be severely damaged.
Even though CFC production
has been nearly halted,
we
can
expect the gasses already
released to continue damaging
the ozone for the
next century.
Burning
fossil fuels causes acid
rain and global warming.
Though not as devastating as
global
warming,
it nevertheless is harming many
fish populations and trees,
corroding bridges and
buildings,
and contaminating drinking water.
Airborne toxins and air
quality in general are
also
serious
concerns for human
health.
Airborne
Toxics are less catastrophic
but highly worrisome air
pollution threats; 2.4
billion
pounds
of airborne toxic substances
released annually into the
nation's atmosphere, including
phosgene,
a nerve gas used in warfare,
and methyl iso-cyanate.
Water
pollution is likewise a serious problem.
About 40% of the world's
surface water is too
polluted
to fish or swim in.
Pollution comes from
agriculture, mines, oil
wells, human wastes,
manufacturing,
detergents, and the food industry,
among other sources. Today,
almost 1 billion
people
lack access to safe water
and the world's per capita supplies of
water are shrinking.
The
pollution of the land by
toxic substances also causes
increased mortality and
illness.
Hazardous
or toxic substances are those
that can cause an increase in
mortality rates or

irreversible
or incapacitating illness, or those that
have other seriously adverse
health or
environmental
effects. Over 58,000
different chemical compounds
are currently being used
in
the
U.S., and the number is
increasing each year. How
many of these chemicals
affect humans,
no
one really knows. The sheer
volume of solid waste is staggering:
each U.S. resident
produces
about seven pounds of garbage per
day. Though this quantity is
massive, it is not even
close
to the quantity of industrial
waste. The EPA estimates
that about 15 million tons
of toxic
waste
is produced in the U.S. each
year. This does not
include nuclear wastes, which,
because
they
are so concentrated and persistent,
present special problems for storage and
disposal. Each
nuclear
reactor produces 265 pounds of plutonium
waste a year, a substance so toxic
that only
twenty
pounds would be sufficient to
cause lung cancer in everyone on
Earth. So far, no one
really
knows how to dispose of this
and similar wastes safely and
securely.
As
if pollution was not serious enough, we
also must consider the
depletion of species,
habitats,
and
natural resources. The world
loses about 1% of its rain
forests each year, and
between 15%
and
20% of species had become
extinct by 2000. Our
consumption of fossil fuels
has recently
been
rising at exponential rates, but
this cannot continue much
longer because we are
coming
close
to the depletion point of
fossil fuels. Minerals are
also being depleted, so we can
expect
them
gradually to become more
scare and expensive. This
scarcity will have a serious
impact
on
the world economy.
The
Ethics of Pollution Control
Businesses
have been ignoring their
impact on the natural
environment for centuries,
largely
because
the economic costs and
harmful effects of this
impact have been unclear.
Businesses
have
treated air and water as free
goods that no one owns. Since
the carrying capacity of
both is
so
large, each individual firm
sees its own contribution to
pollution as negligible.
Combined,
however,
the effects are enormous.
The harm comes not
only from the direct
activity of
businesses.
Pollution also occurs as a result of
consumer use of manufactured
items. The
problems
of pollution have a variety of
origins, and will require a similarly
varied set of
solutions.
The rest of this chapter concentrates on
a single range of problems, the
ethical issues
raised
by pollution from commercial and
industrial enterprises.
