THE
GLOBALIZATION: THREATS AND RESPONSES
PART-2"
Regulating
Earth -- nature as life
support:
While
the value of most of these
products can be fairly
easily calculated, any other
services of nature do
not
appear
on conventional balance sheets,
but they are equally
essential for the survival of modern
economies.
Their
true worth is often appreciated
only when they are
lost.
Returning
to that apparently worthless swamp,
for example, wetlands
perform a wide range of functions
of
great
value to people -- from acting as a
natural pollution filter and
preventing floods by storing water
during
heavy
rains to supporting wildlife
and recreation.
Forests
help regulate air quality, the
flow of water, and the
climate itself. Although their
relationship with the
atmosphere
is more complex than the common description as "lungs
of the earth," forests store
large
quantities
of carbon that would add to
the greenhouse effect if released into
the air.
Natural
systems provide protection
from a range of catastrophic
events that can devastate
human
communities
-- vegetation helps prevent soil erosion
and reduce the likelihood of
landslides, while
coral
reefs
and mangrove forests act as
barriers against coastal
storms and even tidal
waves.
Interference
with living systems can
also promote the sudden
emergence of human diseases
and crop pests,
causing
great suffering and economic
damage. In attempting to assess the importance of
nature to our lives,
we
should not lose sight of the
value placed on the variety of life on
Earth for its own
sake: this is even
more
difficult
to put a price on, but
nonetheless of deep concern to people of
all cultures.
Whether
it is the uplifting sound of birdsong in a city part,
the reverence for local
species in many indigenous
belief
systems, or the wonder of a child watching
wildlife in a zoo or even on television, appreciation
of the
natural
world is an important part of what
makes us human. Even if our
material needs could be met
with a
much
narrower range of species and
landscapes, many people would
regard this loss as a significant threat
to
their
overall well-being.
