"THE
GLOBALIZATION: THREATS AND RESPONSES
PART-1"
Text
of handout
for
students
Note: In the
Lectures 26, 27 on the global
environment, both the threats
and the possible responses to
the
threats
have been identified and
briefly explained.
Specific
data has been cited to
show how each of the
principal ecosystems of our planet
are being rapidly and
adversely
affected by excessive exploitation of
natural resources.
The
consequential dangers to human survival
and to the survival of many species
are already beginning
to
become
apparent through the loss of
biodiversity, climate change,
pollution, the spread of new
diseases and
viruses
and other perils.
Tangible
and practical sets of
actions involving policies
and programmes have been
spelt out.The elements
in
the
two lectures have been
adapted from a series of publications
prepared as part of the
Millennium
Ecosystem
Assessment series prepared by the
World Resources Institute,
2005; published by Island
Press,
U.S.A.
The
excerpt below is provided to
students purely for
educational and background purposes as
the elements
presented
in the lectures have already
been published in a special newspaper
supplement produced by IUCN
The World Conservation Union on the
occasion of the UN Summit held in
September 2005 in New
York
to
make a mid-term assessment of the
pace of implementation of the Millennium
Development Goals.
The
excerpt below is taken from the
publication titled: "Living beyond
our means" and stresses the
vital
relationship
between the support services provided by
nature to humanity. It is hoped that
students will use
the
information and insights obtained by them
from the lectures and the
handout to bring about
positive
change
for the health and well-being of our
planet earth and of
humanity.
The
Services of Nature
Essential
to our lives
As
human societies become more
and more complex and technologically
advanced, it is easy to gain
the
impression
that we no longer depend on natural
systems.
A
steadily increasing proportion of the
population lives in cities, in
environments dominated by human-built
structures
and machines. Nature may
appear to be something to be enjoyed at the
weekend if we get the
chance,
nice to have but hardly at the
forefront of our daily
concerns.
Even
in rural areas, the conservation of natural
spaces is often seen as a
luxury that has little to do
with the
well-being
of local people -- a swamp, for
example, might be viewed as wasted land,
whose only value is
in
the
crops that could be planted if it were to
be drained.
These
are dangerous illusions that ignore the
vast benefits of nature to the lives of
the 6 billion people on the
planet.
We may have distanced
ourselves from nature, but
we rely completely on the services it
delivers.
Providing
the basics:
At
the most basic level, the food we
eat is a service of nature.
This is most obviously true when it is
obtained
by
harvesting wild species such
as ocean fish: the healthy functioning of the
food chain of the seas is an
asset
of
vast economic value.
Even
food grown in what appear to be the
most unnatural conditions, however, is still a
product of the
biological
processes of nature. Whether it is in the
genetic material from which
seeds or livestock are bred
(or,
with
biotechnology, altered), the soils in
which crops are grown, or the
water that makes the land
fertile:

human
nourishment depends on a natural infrastructure
underlying the skills and technology of
farmers
around
the world.
Apart
from its role in food
production, fresh water is of
course another of the basics of life.
For all the
ingenious
channeling techniques developed since the
earliest civilizations, we still rely on natural
systems to
regulate
the flow of water through the
river basins of the
world.
Even
with the invention of many
synthetic materials other
products of nature are still
used in huge quantities
in
every society -- trees bring
us wood and paper, the fashion
industry needs plant and
animals fibers, and
medicines
derived from nature are in
ever-greater demand.
