Species Extinction
Clara Santoro, CSJ
The earth community is an intricate web of life. Each species has a specific
niche in which it can
flourish and function. The life style of one species
affects the survival of many others; the needs
of one species keeps the others
in balance.
At the present time, we find ourselves in a situation where the unlimited
growth and irresponsible
consuming of the earth’s resources by one species is
threatening the survival of all the others.
That species is homo sapiens,
ourselves. The activities of 5.6 billion humans , with the potential
of more to
come, are presently causing the extinction of other species and the potential
extinction
of many others. We present a threat to life as we know it.
Species become extinct or endangered for several reasons, but the primary
cause is the destruction
of their habitats by the human species. Our
irresponsible need to consume and expand has forced
other species to abandon
their habitats-- consider the raccoons and opossums and even bears seen
in our
urban communities. Since these species have been forced out of their preferred
niches, they
are deprived of the means to reproduce and survive.
Other causes of species extinction resulting from human activities are the
following:
- Pollution
- Drainage of wetlands
- Conversion of shrub land to grazing lands
- Cutting and clearing of forests
- Urbanization
- Coral-reef destruction
- Road and dam construction
- Worldwide commercial exploitation of animals for food and other products
- Non-native species introduced to a new ecosystem in which native plants
and animals have
no natural defenses against them.
Extinction does not require every member of a species to die within a short
period of time. All that
is necessary is that the species decline to a level
where the reproduction rate is no longer viable.
According to information
gathered from the National Resources Defense Council, the
Environmental Defense
Fund, the U.S. Fish and Wildlife Service, The National Wildlife Federation
and
the Natural Resources Defense Council the following statistics are valid:
- 137 species are estimated to go extinct each day.
- 50,000 species are estimated to go extinct each year.
- 78 species were on the original United States endangered species list.
- 1,201 species were on the U.S. endangered species list as of October 1999.
- 43 percent of the endangered and threatened animals in the U.S. depend on
wetlands.
- 40 percent of all modern medicines are either modeled on or synthesized
from natural
components derived from various species.
- 95 percent of known plant species have yet to be screened for their
medicinal value.
- 30 million species of plants and animals—more than half of all life
forms on our planet --
live in rainforests.
- 2.4 acres per second ( equivalent to two U.S. football fields) of
rainforests are being
destroyed per second.
While you were reading these statistics, approximately 149 acres of
rainforest were destroyed and
within the next hour approximately 6 species will
become extinct. These magnificent plants and
animals which took millions of
years to evolve and are so rich in their contribution to the entire
earth
ecosystem will die out never to be seen again.
The most important task for the human community at this time is to realize
the damage it is
inflicting and take responsible and united action to curb our
wanton exploitation of the rest of the
community with
which we share our home planet. We need to realize
not only the intrinsic worth
of every other being but the sobering fact that in
destroying them we will ultimately destroy
ourselves.
Over
Consumption
Kathleen Loughlin, CSJ
We have not inherited the world from our forebears--we have
borrowed it from our children.
Kashmiri Proverb
Since the end of World War II, we in the
United States and the first world countries of Europe have
increased our standard
of living based on the economic principle of consumerism. The One Look
Dictionary defines this principle as the "utilization of economic goods
to satisfy needs." The United
Nations Human Development Report 1998
emphasizes that since the beginning of the 20th
century
more people are better fed and housed than ever before. Living standards
"have risen to
enable hundreds of millions to enjoy housing with hot water
and cold, warmth and electricity."
These accommodations --benefits for those members of
the human family
that possess them--are
the hallmark of a robust consumption based on
individual and societal need.
In the Western world, however, consumption
has shifted from fulfilling needs to over consumption
--the acquisition of
economic goods for their own sake. Need is no longer the norm, but rather
the
purchase of luxuries guides buying power. Reflective of this reality, millionaire Malcolm
Forbes
once quipped: "He who dies with the most toys wins." The far
reaching effects of over consumption
however, are often not visible to the eye or they
exist in countries far removed from first world
countries. In the United States
alone, we account for 5% of the world population and consume
nearly 30% of
global oil. Other statistics that further emphasize the disparity of rich
and poor
nations and the reality of over consumption are the following. The richest
fifth of the world:
-
Consume 45% of all meat and fish, the
poorest fifth 5%.
-
Consume 58% of total energy, the
poorest fifth less than 4%.
-
Have 74% of all telephone lines, the
poorest fifth 1.5%.
-
Consume 84% of all paper, the poorest
fifth 1.1%.
Own 87% of the world's vehicle fleet,
the poorest fifth less than 1%. (Shah)
The citing of these statistics of over consumption
vividly convey the rich-poor divide that exists in
our world today. It also provides a context for examining the
effects of over consumption that are
not readily seen--the influence on our
environment. Land degradation, pollution, and global
warming are three threats to life as we know it on our planet.
Each is a direct result of over
consumption. An example: to stock the restaurants
in the United States intensive breeding of live
stock and
poultry is necessary. This breeding directly leads to deforestation and contamination of
water resources.
For every pound of red meat, poultry, eggs, and milk produced, farm fields lose
about five pounds of irreplaceable top soil (Shiva, pp.70-71). To understand the magnitude
of this
loss is to realize that in the eco-system one change affects all others.
For instance, a decrease in
farmable land may increase the presence of pests and disease which
we are not prepared to
combat. The immensity of this threat is more fully
realized when the amount of resources used to
raise beef and
other products for restaurants and home is understood. Shiva writes:
- Animal farms throughout the world use mostly 40% of
the planet's total grain production.
The United States uses 70% of its grain
fed to livestock.
Not only these types of food that are produced, but other
consumer goods pose a series of threats
for the human family. "The
production, processing, and consumption of commodities requires
extraction of
natural resources (wood, ore, fossil fuels and water); it requires the creation
of factory
complexes whose operations create toxic byproducts, while the use of
commodities themselves e.g. automobiles [computers] creates pollutants and
waste" (Robbins).
Concretely, scientists have identified automobile
emissions as a contributing pollutant to global
warming--a reality that is not
only translated into warmer winters in some areas, but a greater
occurrence of
hurricanes and droughts. Also longer spells of dry heat and intense rain
are trends
that are observed throughout the world. This change in climate,
in turn, affects the production of
food and creates conditions for infectious
diseases whose control can not be anticipated.
Is it feasible that these environmental concerns are
influenced by our over consumption? Are we
asked to change our lifestyles
in a way that is not consistent with our present standard of living?
These
questions must be answered individually. One response is the growing movement
in simple
living where individuals voluntarily make their buying choices out of need
rather than luxury. But
these questions also need to be answered by the
world community. A beginning might be to
address several issues as we make decisions
about consumable goods. Shah suggests asking:
- How are the products and resources we consume actually
produced? What are the impacts of
that process of production on the
environment?
- What are the impacts of certain forms of consumption
on the environment, society,
individuals?
- What is a necessity and what is a luxury?
- Business and advertising are major engines in
promoting the consumption of products so
that they may survive. How much of
what we consume is influenced by their needs versus
our own needs.
Having reflected on these questions, we may as a world
society decide to
have:
- a consumption based on need rather than luxury,
- a consumption that is shared by all,
- a consumption that builds on human capabilities,
- a consumption that is socially responsible,
- a consumption that is kind to our environment. (Shah)
In short, our consumer choices can become a well spring
of hope rather than a threat to the
human family.

Depletion
of Water
Patricia Monahan
“The life and health of our planet is completely
dependent upon water. It carries all present life, the
seeds of future life, and
the memory of past life in its flow. Water is the mediator between life and
death between being and nothingness, between health and sickness.
Unfortunately, over the years we have lost our connection with this l
ife-giving
and life-supporting sacred substance." Charlie
Ryrie, The Healing
Energies of Water
Sandra Postel, Director of the Global Water Policy Project,
is well known as the author of two
significant books, The Pillar of Sand: Can
the Irrigation Miracle Last? and The Last Oasis. In an
address to the World
Watch Institute Forum entitled "International Security and Water
Scarcity," she
stressed that water is a unique resource for three critical
reasons.
-
Water is the matrix of culture and the basis of life. Nothing on
earth, plant or animal in the
terrestrial environment, can survive without fresh
water. This is the reality one must keep in mind
when discussing water.
-
Unlike oil and most other resources of concern, water has no
substitutes in most of its uses.
Water is needed to grow wheat and corn, to make
paper, to cleanse and refresh.
-
Fresh water flows naturally across political boundaries.
These three attributes explain why issues of water rights,
water access, water allocation and control
over water can become both
complicated and contentious.
Today the world is moving headlong into a period of fresh
water shortage. By 2015, it is estimated that
nearly three billion people, about
40 percent of the projected population at that time, will be living in
water
stressed countries. The citizens of these countries will have difficulty
locating enough fresh water
to meet their daily water requirement for food, as
well as for industrial and household uses.
This water shortage will most assuredly increase
competition for water between and among countries.
How nations and economies
deal with this increased competition will have far-reaching consequences. Water
induced violence is already threatening social and political stability around
the world.
World Watch Fact Sheet on Water Depletion:
-
Since 1950, the global renewable freshwater supply per person has
fallen 58 percent as world
population has swelled from 2.5 billion to 6 billion.
-
Today Asia has approximately 60 percent of the world’s people
but only 36 percent of the world’s
renewable freshwater.
-
Currently water-stressed countries in Asia, Africa, and the Middle
East account for 26 percent
of global grain imports. China, India, and Pakistan,
all presently grain self-sufficient, will likely join
the ranks of grain
importers due to decreasing water availability.
-
An analysis of 1,831 international water-related disputes over the
last 50 years reveals that two
thirds of these encounters were of a competitive
nature while one fourth were hostile.
-
Water treaties that provide for effective monitoring and
enforcement are critical worldwide.

Water Pollution
"Water and life are inseparable. It has the
ability to confer life, uphold life, and transform death into
new life.
Throughout human history water has been connect to mystery, or used as a symbol
of mystery. Until we regain an attitude of respect and reverence for water, we
are threatening our life and the life of the planet on which we live."
Charlie Ryrie, The Healing Energies of Water
Payal Sampat, author of Deep Trouble: The Hidden Threat of
Groundwater Pollution, explains
that "Groundwater contamination is an
irreversible act that will deprive future generations of one of life’s
most
precious resources. He points out
that groundwater is an essential resource for sustaining
civilization.
Approximately 97 percent of Earth’s liquid freshwater is stored in underground
aquifers.
Almost one third of humanity depends completely on groundwater for
drinking. This includes some of
the largest cities in the developing world, such
as Jakarta, Dhaka, Lima, and Mexico City. Nearly 99
percent of the rural U. S.
population and 80 percent of India’s villagers, depend on groundwater for
drinking.
According to Payal, groundwater irrigates some of the
world’s most productive cropland. More than
half of irrigated farmland in
India, and 43 percent in the United States, are watered by groundwater.
Irrigation already accounts for about two thirds of water use worldwide. As
rivers and lakes are
dammed, dried up, or polluted, and as food demand grows in
the next 50 years, farmers will become
increasingly dependent on ground water
for irrigation.
World Watch Institute reports that toxic chemicals are
contaminating groundwater on every inhabited
continent. This degradation of
water is endangering the world’s most valuable supply of freshwater.
This
first global survey of groundwater pollution shows that a toxic brew of
pesticides, nitrogen,
fertilizers, industrial chemicals, and heavy metals is
fouling groundwater everywhere, and that the
damage is often in the very places
where people need water the most.
"One of the most disturbing aspects of the problem is
that groundwater pollution is essentially
permanent," explains Sampat.
Water recycles very slowly underground, too slowly to flush out or dilute
toxic
chemicals. Water that enters an aquifer remains there for an average of 1,400
years, compared
to only 16 days for rivers.
The urgency of preventing groundwater contamination is made
obvious when you examine the cost of
cleanup. Water utilities in western United
States spend $400 million each year to treat water for just
one chemical, the
pesticide atrazine. According to the U. S. National Research Council, initial
cleanup
of contaminated groundwater for some 300,000 sites in the United States
could cost up to $1 trillion
over the next 30 years.
To preserve this invaluable resource, human societies must
make major changes in the way they grow
food, manufacture goods, and dispose of
waste. Large corporations and companies must assume the
greater responsibility
for their toxic discharges. Sixty percent of the most hazardous liquid waste in
the
United States, 34 billion liters per year of solvents, heavy metals, and
radioactive materials, is injected
directly into deep groundwater via thousands
of "injection wells.
World Watch Fact Sheet on Groundwater Pollution:
-
One third of the wells tested in California’s San Joaquin Valley
in 1988 contained pesticide
DBCP at levels 10 times higher than the maximum
allowed for drinking water, more than a
decade after the chemical was banned.
-
The U. S. Environmental Protection Agency estimates that about
100,000 underground storage
tanks for gasoline are leaking chemicals into soil
and groundwater.
-
India’s Central Pollution Control Board surveyed 22 major
industrial zones in the late 1990’s and
found that groundwater in every one of
them was unfit for drinking.
-
In the northern Chinese provinces of Beijing,
Tianjin, Hebei, and Shandong, nitrate
concentrations in groundwater exceeded heath guidelines in
more than half of the locations
studied in 1995.
-
In Manila, where groundwater levels have fallen 50-80 meters
because of overdraft, seawater
has flowed 5 kilometers inland, contaminating
city’s aquifers with salt.

The Rainforests—Who
Knows?
Brigid O’Meara, CSJ
Things are looking really bad for our rainforests,
so fabulously rich in plants, animals, and insects
(30 million species!).
Take a look at how fast they are dying out:
Think about that.
About six species of trees per hour become
extinct, primarily because of destruction of their habitat through
logging, mining, clearing for cattle ranching, building of dams and
roads and uncontrolled development. At root are the materialistic
demands of industrialized countries.
If we continue down this road, all tropical rain forest
ecosystems will be only a memory by 2030.
Think about that.
But all is not lost.
We humans are still capable of protecting our own environs, our
own future. It will require repairing damage done and ensuring needed
biodiversity to provide for generations yet unborn.
-
We must stop
destruction of the rainforests and
vastly expand areas to be protected.
-
We need to improve gene banks,
which store seeds, embryos or germplasm.
Although
this is a stopgap and imperfect way of preserving
species, it is a start.
-
.
Most importantly, we must support national and international
organizations’ efforts to advise and inform governments.
Power of government is necessary to tame the onslaught of corporate rape of our rainforests,
Surely all this seems so big and so beyond
the power of the individual, but individuals can do
something by
thinking twice.
We can cut back on the use of paper.
Skip paper plates, towels, etc. and use cloth bags for shopping. Buy recycled
paper products.
We can curb our use of oil
by using cars with good gas mileage, trying to do several
errands in
one trip, and car pooling when possible.
-
We can reduce our consumption of beef.
Cattle require huge tracts of grazing land, which cause the
further destruction of the rainforests.
-
We can push for the funding of
mass transit.
-
We can keep our eyes open to hold corporations accountable.
-
We can write letters to express concern for the rainforests.
(www.ran.org)
-
We can support actions to protect endangered areas( www.ran.org).
-
We can support the Rainforest Action Network, which
coordinates actions among
interested individuals (www.ran.org).
God has worked out such a wonderful
home for us on this earth, incredibly complex and
interdependent.
The harm we humans have done to this splendid plan has endangered
not only
the forests and their inhabitants, but our own well being as
well. You can help.
Think about that.

The Gift of Water
In Honor of the International Year of Fresh Water
By Patricia A. Monahan
What aspect of water delighted you most this summer? Was it sitting
beside a stream listening
to the comforting sounds of water gurgling over rock? Was it a friend’s
offer of a cold glass of
water after a stint of gardening? Perhaps it was a swim at the ocean, or
a walk along the beach.
Maybe you recall the soothing relief of soaking tired feet in a pan of
warm water. Whatever your
water delight, during this International Year of Fresh Water, we are
reminded that water heals,
refreshes, soothes, cleanses, and blesses.
Though colorless, water enables us to see the colors of the rainbow.
While having no form itself,
it gives form to everything. Billions of years old, water is constantly
renewing itself. Water has the
ability to confer life, uphold life, and to transform death into new
life. Every drop of water is a
microcosm of the universe, carrying information from ancient eras and
from worlds we have
yet to imagine. Water is everywhere and in everything. Water is sacred.
In today’s fast-paced society there is a deep desire to reconnect
with the sacred in everyday life.
The ordinary and commonplace can be sacred. This idea has always been
central to many belief
systems from the East, and it is no accident that many Eastern societies
have a more respectful
attitude toward water than that shown in the West. From similar roots
Eastern and Western
societies developed along markedly different paths over the last two
thousand years. While
the West pursued economic dominance and power for hundreds of years, the
second half of
the 20th century saw a renewed interest by Westerners in
Eastern beliefs and practices, and
a renewed search for spirituality.
Regardless of religious belief, water is a magical, mysterious, and
powerful substance that
bestows life. Every ancient culture revered water. Indeed, all ancient
deities were water gods.
The Sumerian’s word mar meant sea, but it was also the word
for womb; a was the word for
water, and also meant sperm, conception, and generation. The Hebrew
language includes the
ideogram Mem, deciphered as mother, life, womb, or sea.
"Everything was water," say Hindu
texts, and in the Tamtric manuscripts water is prana, the vital
breath that brings life. Water and
life were one and the same. Living in dialogue with water connects the
physical, emotional, and
mysterious worlds.
Throughout history "holy" water has been understood to heal
symbolically, and in some instances,
physically. Baptism is probably the universal symbol of purification and
regeneration. It was first
introduced in the rites of Egypt. It is also rooted in Shinto,
Confucian, and Hindu customs of
bathing in sacred waters to symbolically cleanse all sin. The baptism of
Jesus by John prepared
him to accept his mission on Earth as the Son of God. In Western
culture, baptism may be the
only ritual associated with water that is recognized as having a
spiritual element. While there are
many who practice their faith, others who may never step inside a church
for religious reasons
still want their children to be baptized even though it may seem
unconnected to other aspects of
their life. There remains a need to recognize our spiritual nature, a
desperate desire to find
meaning on a deeper level within the context of the Earth community.
Modern industrialized people, detached from the land and the seasons,
often forget the connection.
When it rains, we complain of the inconvenience, or how it interferes
with our plans. Yet, lack of rain
causes the greatest complaints when authorities impose limitations on
water usage and people
can no longer water lawns and gardens. God forbid that water be turned
off for even a few hours
during major plumbing and construction jobs. The link between water and
fertility is only recognized
when it impinges on private demands.
The irony is that because water has been taken for granted for so
long, water shortages even in
the Western world are threatening human health and the health of the
environment. Humans have
forgotten their dependence upon water. Until we regain an attitude of
respect and reverence,
the entire planet is at risk.
If we reflect upon our dependence on water, we will begin to use it
more carefully. Unfortunately
it retains only the faintest vestige of the sacred for most of us. Our
exploitation of water has been
continuing for centuries, but has become more obvious in the last 65
years. Now much of the
world has piped water, and piped sewage systems, too. We no longer think
about how we get
clean water, how we dispose of it once we have dirtied it, or how much
of it we use. If we take the
time to appreciate the marvelous substance water is in itself, we will
readily realize that water is
the source of life, and if we appreciate its qualities we can become
empowered by it.
That doesn’t mean we have to completely change our lifestyles, but
we have to become more
conscious of the world around us and reconnect with the more spiritual
side of life in nature. Take
time to reflect on or meditate by water… a stream, a lake, a
river, an ocean. Realize that water is
alive. It has reflected and carried the beliefs of every society since
time began. It works in
mysterious ways, but, without it, all life stops. Once we begin to
understand the true nature of
water, we will realize that it is the key to our spiritual, emotional,
and physical well-being. As we
reconnect with this sacred element, we may be closer to reconnecting to
the true Source of
Divine Life.

Soil Erosion
Mary Lou
Buser, CSJ
Soil erosion is a natural phenomenon which has been happening for
over 400 million years, or since the first plant grew in soil.
The primary causes of soil erosion are water and wind.
Nature, left to itself, erodes soil at about the same rate
as it produces soil. (Soil
is produced by a process known as weathering, the wearing down of
rocks by various means) Humankind,
however, with the onset of agriculture, cattle grazing, lumbering
and other means of deforestation, along with development of
natural lands for homes and industry is quickening the pace of
soil erosion to a degree that is becoming of great concern to
scientists, conservationists and any who are concerned about the
future of this earth.
Water and wind are the major causes of soil erosion.
The splash of the water drop on the soil detaches particles
that are light and loose. These
particles can be native to the soil as well as man made additions such as fertilizers and pesticides.
The detached particles are then transported by gravity or
the rush of rapidly moving water to lakes, streams and rivers
where the particle build up is called sediment and the process
called sedimentation. We all learned about the Mississippi Delta
which is a classic example of this process.
Wind can also detach particles from soil though it is not as
forceful in accomplishing the process as is water.
The effects of the erosion process at the site of the detachment (on
site erosion) are significant; the most significant being the loss
of top soil which contains the nutrients necessary for plant
growth. Top soil is being lost in the U.S. at an alarming rate and the long term effects of this are very
serious. However, in the short term farmers have at their disposal synthetic
fertilizers which can be applied to the depleting soil for a “quick
fix” and the long term effects of excessive soil erosion go
ignored. In poor,
developing countries this “quick fix” is not readily available
and their crops are not healthy or they are forced to buy
fertilizers from the developed countries that produce them.
The farmers in poor, developing countries are very much
aware of the on site effects of excessive soil erosion.
The effects of the soil erosion process as the particles are
transported (off site erosion) are also significant. Particles that are detached from the land in one particular
area can create a nutrient rich environment in other areas as the
sediment is transported as well as when it comes to rest in a lake
bed or mouth of a river. This is a positive effect.
However, since most of our macrofarms require vast amounts
of synthetic fertilizers and pesticides, these too are transported
throughout our waterways causing pollution and unhealthy sediment.
Many studies are underway regarding the effects of climate change on
soil erosion. It
appears that most scientists agree that global changes in climate
are hastening the rate of soil erosion on earth today.

Pollution
and Climate Change
Joan Gallagher, CSJ
Climate can be defined as the
“expected weather” of a region or zone on Earth.
Earth’s climate has
changed during its 4.2 billion years of
existence. During the
evolving years of Earth as we know it, the major
causes of climate
change were due to:
Ø
Changes in Earth’s orbit around the sun
Ø
Changes in the amount of energy coming from the sun
Ø
Changes in ocean circulation
Ø
Changes in the composition of Earth's atmosphere
Energy from the sun drives Earth’s
weather and climate and heats Earth’s surface.
In turn Earth radiates
energy back into space.
Atmospheric greenhouse gases, such as water vapor, carbon
dioxide, methane,
nitrous oxide, trap some of the outgoing energy.
For the past 10,000 years these greenhouse gases have maintained an
average and hospitable
temperature of 59°on our planet.
However with the industrial revolution there has been a larger
emission of
greenhouse gases. The
increased concentration of these gases has enhanced the heat trapping
capabilities of Earth’s atmosphere.
Over the past century it has been observed that the major causes of
climate change have shifted as a
result of human activities.
These activities have raised the levels of greenhouse gases as
follows:
Ø
Burning of fossil fuels have increased carbon dioxide by
30%
Ø
Energy and transportation have increased nitrous oxide by
15%
Ø
Land use and food have more than doubled concentrations of
methane
The overall affect of the unnatural accumulation of these gases has
increased the global surface temperatures
1.0º. The 20th
Century’s 10 warmest years have occurred in the last 15 years of the
century. The
increased
temperature has caused sea levels to rise 4”-8” this past century.
Worldwide precipitation
over land has increased 1%.
In the United States the frequency of extreme rainfall has increased.
Remember the spring of 2003?
These changes validate the Intergovernmental Panel on Climate Change
(IPCC)
reports of what we
can expect if emissions of greenhouse gases do not
change:
Ø
Greater weather extremes, i.e., stronger storms, longer and
drier droughts, heavier rains and
increased numbers of floods
Ø
Altered patterns of climate and weather-less rainfall in
the interior continents
Ø
Increase in sea levels
Earth’s atmosphere does not
distinguish where emissions come from.
A greenhouse warmed world
sets off the natural climate changes of
the planet to more drastic climate changes for the planet.
The impact on the global community:
Ø
Displacement of persons due to rising sea levels
Ø
Unpredictable fresh water supply
Ø
Reintroduction of diseases such as malaria
Ø
Loss of ecosystems and biodiversity
Ø
Diminishment of ocean phytoplankton which supply 70% of the
oxygen we breathe and which
are a major consumer of carbon dioxide
Ø
Food insecurity with diminished agricultural production
which in turn can set off the world’s
economy (It should be noted that
genetically engineered food do not have the natural coping
mechanisms to
deal with changes in temperature, sun and moisture)
In December 1997, the world’s
national governments met in Kyoto
, Japan , to negotiate a treaty
to start dealing seriously with climate change.
The framework of the treaty reduces emissions of greenhouse gases
and sets emissions caps. The
Kyoto Protocol will only become international law when it is ratified by
at least 55 countries
To
date 22 countries have signed on, the United States of America
not being one of them.
What can one do locally to assist global efforts to halt unnatural
changes in climate:
Ø
Write government officials encouraging the United States
to sign onto the Kyoto Protocol
Ø
Shift mindset from dominance and power to one of reverence
and respect
Ø
Acknowledge worth of creation
Recognize the other and one’s responsibility towards the
other
Ø
Seek to employ alternative forms of renewable energies,
i.e., Solar, Geo-thermal, wind, etc.
“In retrospect it will be clear.
A hundred years from now, people may well
remember the 1990’s not as the decade of the Internet’s
spread or the Dow’s
ascension
but as the years when global temperatures began spiking upward-
as the years when rain and
wind and ice and sea water began irrefutably to
reflect the power and
heedlessness of our species. But
how bad it will get
depends on how deeply and how
quickly we can feel.”

An
Update: Bottled Water
We can’t help but notice that our supermarket shelves are lined with
various brands of bottled water and it’s almost
stylish to carry a bottle of water and sip from it regularly.
This is so because we’ve learned that it’s good for us to
drink plenty of water and bottled water is safer and healthier to drink
than water which comes directly from the faucet.
According to an article in a recent issue of “YES!” magazine,
bottled water may not be better for us than tap water, after all.
The
article tells of a study done by the Natural Resources Defense Council (NRDC).
While it is a complex and complicated issue one basic outcome of
the study is that about one third of the 103 brands of bottled water
tested
had microbial content in excess of state regulations. Although some tap
water may also be contaminated the EPA (Environmental Protection Agency)
guidelines call for near constant inspection of tap water but it does not
oversee
the bottled water industry. The
industry tests its own water and some pathogens are allowed if a
disclaimer is put
on the label. The Food and Drug Administration monitors only the bottled
water that crosses state lines. Each
state is responsible for monitoring the water which is produced and sold
within that state and only seven states have effective regulations. For these reasons it is
important to seek further information in an effort to make informed decisions about the
water we drink.

Mercury
The Bush Administration has made a proposal that will allow the country's
dirtiest power plants to continue to release hazardous levels of mercury into the environment. Mercury is known
to cause mental retardation, learning disabilities and attention disorders in newborns and growing
children. This plan signals a complete change from the Clinton-era decision to make industry reduce its mercury
emissions by 90 percent by the year 2007. Mercury spewing from power plant smokestacks falls into lakes,
streams and ponds accumulating in fish and endangering humans and animals that eat fish. The
administration's retreat on mercury is more shocking given the fact that it came only days after the Food and Drug
Administration warned pregnant women and nursing mothers against eating more than two servings of a variety of
fish and not more than one can of tuna per week because of the high levels of mercury in fish.

Exxon
Mobil's Climate Footprint
"
For the first time, the historic contribution of one company
to global climate change has been calculated. The assessment findings of ExxonMobil's historical emissions
has significant implications for the company's
legal exposure and for its stockholders.
Friends of the Earth commissioned two studies that showed
ExxonMobil, including its predecessors, caused 4.7 to 5.3
percent of the world's manmade carbon dioxide emissions
between 1882 and 2002. Carbon dioxide
emissions are the principal cause of global warming.
Despite U.N .scientists findings in 1996 that man-made
pollution is having a discernible influence on the global
climate, seven out of the ten worst years of ExxonMobil's
emissions occurred after 1996.
ExxonMobil has repeatedly attempted to undermine the
scientific consensus on climate change and actively resisted
attempts to limit carbon dioxide emissions through law."

Air Pollution
" By the end of the 20th century, medical research
had confirmed that air pollution from cars and utility plants
makes people sick. Coal burning utility plants emit nitrogen oxide which affects
the ozone layer and accounts for the clouds of smog hanging over our cities. Acid rain is formed when nitrogen oxide combines
with sulfur dioxide, water and oxygen. Burning coal
yields mercury as a vapor which accumulates in swordfish and
tuna and results in brain disorders in fetuses and affects
young
children. Every year 30,000 Americans die from pollution related ailments."

Signs of a
Changing Planet
Carbon Dioxide is a key contributor to global warming in the
atmosphere. Although the United States still emits more Carbon
Dioxide than any other
nation, China and India may be contributing to an increasing rise in temperature by
burning more fossil fuels.
According to recent
calculations by Professor Curt Davis at the University of
Missouri-Columbia, the higher elevation portions of ice sheets in
Greenland are thinning at the rate of four inches each year. The coastal glaciers are
diminishing more rapidly losing three to six feet of ice a year.
The Atlantic
Ocean's tropical and subtropical regions are getting saltier.
The journal NATURE published a study indicating that higher than average
temperatures are evaporating more ocean water from the hottest parts of the world.
This water eventually condenses at the poles where the oceans are becoming less salty. The
imbalance disrupts the flow of water north and south in the Gulf Stream. If this continues at its
current rate , winters in northern Europe could cool by 9 to 18
degrees Fahrenheit within half a
century.

BUSH
IGNORES HIS OWN PROMISES ON WETLANDS
Last week, President Bush said he is working to "restore,
improve and protect at least 3 million wetland acres over the
next five years."[1] But according to a new report released
today, the Bush administration has actually done the reverse by
using a key court ruling to encourage a severe degradation of
wetlands throughout the country.
As the Washington Post reports, the Bush administration
"has allowed developers to drain thousands of acres of wetlands under a policy adopted last year." The study,
which documents the administration policy, was conducted by four nonpartisan environmental watchdog groups and based on documents
acquired through the Freedom of Information Act. It found that
the Bush administration's interpretation of a 2001 Supreme Court
decision has ensured that developers are
allowed to run
roughshod over previous efforts to protect fragile wetlands.[2]

Accelerated
Global Warming
Jacqueline McGlade, executive director of The European
Environmental Agency, urged action to halt accelerating global warming or face deadly heat waves and floods such as those that
killed thousands and burned up crops last summer. The agency
warned that much more needs to be done and fast. It said
rising temperatures could eliminate three-quarters of the Alpine
glaciers by 2050. Global warming has been evident for
years but the problem is becoming acute. It is believed to
be
intensified by human activities especially emissions of heat-
trapping greenhouse gases such as carbon dioxide from the burning of fossil fuels. The European Union has been a
leader in pushing for the implementation of the Kyoto Protocol,
a UN pact drawn up in 1997 to reduce carbon dioxide emission
worldwide by 2010 to 8% below 1990 levels. All 25 EU
members are among the 123 countries that have ratified the pact.
It isn't in effect because it hasn't reached the required number
of nations to ratify it. The United States ,which is the
world's biggest emitter of greenhouse gases, has refused to
ratify the pact arguing that the agreement would hurt its
economy. Russia has not signed either.The three hottest years on record - 1998, 2002, and 2003-
occurred within the past six years with the average global
temperature now rising at almost 0.36 degrees per decade.

Carbon Dioxide Levels Rise Abruptly
“Levels of carbon dioxide in the atmosphere have jumped abruptly,
raising fears that global warming may be accelerating out of control. Concentrations of this gas rose by a
record amount in the past 12 months. It is the third successive year in which
these concentrations have
increased sharply--an unprecedented triennial surge. Even the
Pentagon has issued a warning that the planet could experience abrupt
climate change in the not too distant future and that the consequences–large
masses of people being displaced or starved–pose the greatest security threat to the United States.
Other evidence suggests time is running out:
- In 1910 there were 150 glaciers in Glacier
National Park; now there are fewer than 30.
- Lobsters have sickened and died due to
increased water temperatures.
- This Spring, hundreds of thousands of Scottish
seabirds failed to breed.
Yet the United States and the
World Bank undermine efforts to curb global warming. For example:
- The US allows the auto industry to drag its
feet in the development of fuel efficient automobiles.
- The burning of jet fuel and exhaust from
planes play a significant role in climate change.
We need to elect competent
leaders who will be part of the solution in resolving these issues.”

Signs

"An odd thing happened in the Scottish isles this
summer: seabirds produced scarcely any young. Most of the avian species in this bird-watchers paradise-- including guillemots,
Arctic Terns, and Shetland kittiwakes---depend on sand eels -- small ,silvery fish that feed on plankton.
Scientists believe that the plankton are moving north as ocean temperatures rise, breaking the food chain and
leaving the rugged islands' birds too hungry to breed."

The
Oil Industry Eyes the Arctic National Wildlife Refuge Again
"The
Bush Administration, Congress, and the oil industry are at it again,
pushing to open the Arctic National Wildlife
Refuge in Alaska to oil drilling, a move the Senate rejected last year.
Known as "America's Serengeti," the Arctic Refuge is home to polar bears, caribou, migratory birds and other
wildlife. Despite widespread public opposition to
drilling in sensitive wildlife habitat, the battle could start again in
early 2005. Speak out - tell President Bush and
Congress that Americans oppose trading wilderness and wildlife for more
global warming pollution and a mere six-month supply of oil."

America's
Waters: Vulnerable to Development Pollution
Bush
administration policy dubbed "Reckless Abandon".
"Nearly two years
after the Bush administration issued a policy directive instructing
federal agencies not to protect the bulk of America's waters, a new report from Earthjustice and three other
environmental groups shows that clean water protections are being withdrawn from streams, wetlands, lakes, and rivers
across the country.Reckless Abandon: How the Bush Administration is Exposing America's Waters
to Harm is based on federal documents obtained by the four groups from the US Army Corps of Engineers.
Through 15 case studies, the report demonstrates how the administration's January 2003 directive has prompted federal
regulators to stop using the Clean Water act to protect waters including an 86-acre Lake in Wisconsin, a 150-mile long
river in New Mexico, a 4000-acre tract of wetlands in Florida, and a 70-mile long canal in California that even serves as a drinking water supply.
The directive made clear that no prior permission is required for EPA or
Corps field staff to ignore Clean Water Act protections and allow
industrial facilities, developers and others to pollute, fill, or destroy
these waters. In addition,the policy excludes from protection several types of waters found across
the country that provide critical habitats for an array of migratory birds, amphibians, and other wildlife.
The
report is available online at: http://www.earthjustice.org/

"
The Endangered Species Act
States that when an agency plans to do something that might have a
deleterious effect On a protected species it must consult the agencies that employ wildlife
specialists, namely the Fish and Wildlife Service or the National Marine Fisheries Service.
The issue recently surfaced when Earth Justice sued the EPA for failing to
protect salmon bearing streams from a wide
range of toxic pesticides. That suit resulted in a court order requiring
the imposition of a buffer zone and the placing of warnings in places where the pesticides are sold.
Soon after the court issued its order, the EPA issued regulations
announcing that it will no longer consult NMFS or FWS but will instead ask itself whether the various pesticides will harm
salmon and other protected species. this has
profound implications for scarce wildlife in every corner of the land and
appears to be in violation of the law.

Long
Island
Water and Organic Gardening
Mary Lou Buser, CSJ
We are all aware of the importance of water.
We know we can’t live without it. We are
also aware that potable (drinkable) water is becoming scarce; in some parts of our world
it is almost non-existent.
We here on LI have always had plenty of water which
we pump from underground aquifers. These
aquifers have been in place since the
glaciers receded about
10,000 years ago and are replenished by precipitation
– a wonderful water cycling process.
With the increase in population, farming and industry
over the last hundred
years or so water is taken from the
aquifers at a faster
pace than it can be replenished. This is causing the salt water of the Atlantic Ocean
and Long Island Sound to
encroach upon and shrink the fresh water supply within
the aquifers. There is additional concern about toxic chemicals which are leaching
into and contaminating our water supply.
We know we must conserve water. Though
conservation by individuals is important,
conservation by farmers is even more important. It is estimated that 60 – 70% of
potable water is used to irrigate farmland in the United States. Organic farmers and
gardeners are on the forefront of conserving
water. Since soil rich in organic
matter
tends to hold moisture, organic farming and gardening requires less
watering.
Also, these farmers and gardeners try to use water more efficiently by directing
the water to where it is needed -- at a plants roots.
The organic garden in Brentwood uses a drip watering system. Thanks to our volunteer,
Ernie Herrington, we
have a very effective drip system which Ernie hopes to make
even more effective next year.
This is but one way we can help to
conserve water on Long Island
.
Organic
Garden
Many
people are becoming more aware of the nutritional
advantages of eating food shortly after it’s
harvested. They
are also aware that the energy derived by eating
lettuce or spinach shipped from California is
dwarfed by the energy spent in processing,
packaging and shipping that lettuce cross country.
We work a natural garden on our Brentwood grounds
because we are aware that all of God’s creation
is sacred and should be treated with respect and
care. One
way we can do this is to counter the industrial
agricultural industry which grows monocultures of
soy, corn and wheat etc. These industrial farmers
use chemical (petroleum based) fertilizers and
chemical pesticides.
Both of these ultimately deplete the soil
of its natural life.
Lifeless soil tends to erode very easily
and of course requires ever more chemicals.
Our choice is to engage in diversified gardening
as a model of sound, natural gardening.
We plant a variety of crops, rotate them
regularly, and use the spent plants, weeds, grass
and leaves (all rich in nutrients) to fertilize
the soil. Nothing is wasted.
Our natural garden is a good example of
sustainability.
As a bonus, diversified gardening attracts
very few harmful insects and those that do come
are quickly repelled by the beneficial insects
that are attracted to our flowers.
Gardening in this manner keeps ever before our
eyes the wonders of God’s creation: the good
relationships and cooperation between the plants
and animal life; the diverse dying and rising
within a vegetable garden, and the beauty of the
plants, flowers and tress.
We welcome you to visit our garden.
In season, come and taste strawberries
picked that very day, peas that can be eaten right
from the bush and tomatoes picked at the peak of
ripeness. We
also grow squash, potatoes, eggplant, lettuce and
herbs which you probably would not want to eat at
the garden, but are available for you to take home
for cooking.
If you wish you may come to the garden to just sit
and relax. You’ll
be entertained by the bees which journey from our
bee hives (which are at a safe distance) to
partake of the nectar provided by the flowers in
the garden. In
return the bees do a good bit of pollinating as do
the butterflies and various birds that come to
visit. We
