Sustainable
Development : What is it?
In this issue we present a little primer of the latest enviromental
terms:
The most commonly used definition of sustainable development
comes from the report Our Common Future, more commonly known as the Brundtland
Report, which states that sustainable development is that "meets
the needs of the present without compromising the ability of future generations
to meet their own needs”.
Sustainable development does not focus solely on environmental
issues. The 2005 World Summit Outcome Document refers to the "interdependent
and mutually reinforcing pillars" of sustainable development as:
economic development; social development; and environmental protection.
Environmental Sustainability
Environmental degradation is the damage to the biosphere
as a whole due to human activity. Environmental degradation occurs when
nature's resources (such as trees, habitat, earth, water and air) are
being consumed faster than nature can replenish them, when pollution results
in irreparable damage done to the environment or when human beings destroy
or damage ecosystems in the process of development. Environmental degradation
can take many forms including, but not limited to, desertification, deforestation,
extinction and radioactivity. Some of the major causes of such degradation
include: overpopulation, urban sprawl, industrial pollution, waste dumping,
intensive farming, over fishing, industrialization, introduction of invasive
species and a lack of environmental regulations.
The goal of environmental sustainability is to minimize this degradation
and the processes they lead to.
An Unsustainable Situation
An unsustainable situation occurs when natural capital (the sum total
of nature's resources) is used up faster than it can be replenished. Sustainability
requires that human activity uses nature's resources only at a rate at
which they can be replenished naturally.
Theoretically, the long term final result of environmental degradation
would result in local environments that are no longer able to sustain
human populations to any degree. Such degradation on a global scale would,
if not addressed mean extinction for humanity.
In the short-term, environmental degradation leads to declining standards
of living, the extinctions of large numbers of species, health problems
in the human population, conflicts, sometimes violent, between groups
fighting for a dwindling resource, water scarcity and many other major
problems.
Criticism of the term
Many environmentalists have criticized the term "sustainable development"
as an oxymoron, claiming that economic policies based around concepts
of growth and continued depletion of resources cannot be sustainable,
since that term implies resources remain constant. Resources such as petroleum
are consumed much faster than they are created by natural processes, and
are continually being depleted. However, technologies such as renewable
energy, recycling and the provision of services can, if carried out appropriately,
provide for growth in the economic sense, either without the use of limited
resources, or by using a relatively small amount of resources with a small
impact. In the latter case, even the use of small amounts of resources
may be unsustainable if continued indefinitely.
What is Green Building?
"Green building" is a process to create buildings and supporting
infrastructure that minimize the use of resources, reduce harmful effects
on the environment, and create healthier environments for people.
Resource-efficient or green buildings make both environmental and economic
sense. Buildings are often expensive, wasteful of precious natural resources
and harmful to both workers and the environment. In the U.S. alone, buildings
use 30% of our total energy. Five billion gallons of water per day are
used just to flush toilets. Typical commercial construction generates
2-2.5 pounds of solid waste per square foot of floor space.
The source of the material in this article is the website of the San
Francisco Department of the Environment which publishes the Green Building
Resource Guide, now available.
What is LEED®?
The Leadership in Energy and Environmental Design (LEED) Green Building
Rating System™ is the nationally accepted benchmark for the design,
construction, and operation of high performance green buildings. Green
buildings are designed, constructed, renovated and operated in an environmentally
and energy-efficient manner. To earn certification, a building project
must meet certain prerequisites and performance benchmarks ("credits")
within each category. Projects are awarded the label Certified, Silver,
Gold, or Platinum depending on the number of credits they achieve. This
comprehensive approach is the reason LEED-certified buildings have reduced
operating costs, healthier and more productive occupants, and conserve
our natural resources.
According to WorldWatch Institute, construction, demolition and operation
of buildings collectively consume up to 40% of the earth's energy and
other natural resources. New design practices, technology, and materials
can significantly reduce the resources used in the construction and operation
of buildings and their cost of operation. (This article will be continued
next month).

THREATENED:
Sanchez Creek Canyon, Pacifica
Here’s an almost unknown wild place that is part of Sharp
Park Golf Course and owned by the City of San Francisco.
San Francisco Recreation and Parks Department, the SF Public Utilities
Commission, and the North Central Coast Water District are proposing to
build a pipeline and a 20,000-sq ft water tank platform 40' tall to bring
water to the Sharp Park Golf Course. The tank and concrete pad will transform
the canyon's secluded, wild character. The proposal is on a fast track,
and there is no process for public input. Come to see for yourself!
Hikes
Sanchez Creek Canyon, Pacifica
Sunday, February 25, 10 a.m. to noon
Leaders: Jake Sigg & Jon Campo
Join Jake Sigg and Jon Campo on an exploration of one of the Bay Area's
hidden jewels. Sanchez Creek Canyon, just 15 minutes south of San Francisco
in Pacifica, is home to rough-skinned newts, rubber boa snakes, and federally
listed red-legged frogs. This relatively intact watershed is one of only
two canyons in Pacifica that has never been developed, except for the
presence of a rustic archery range. Expect to see red-stemmed dogwood,
hazelnut, fringe cups, columbine, oceanspray, trillium, slim Solomon,
woodland sanicle, five species of ferns, and many other local gems. Only
an informed public can stop this development, or slow it down sufficiently
to insist on a public process, including hearings. If you missed this
chance to visit Sanchez Creek Canyon call Recreation and Parks Department
General Manager Yomi Agunbiade at 831-2700 or e-mail to Yomi.Agunbiade@sfgov.org
and demand a hearing.
Yerba Buena Island (San Francisco County)
Sunday, April 29, 10 a.m. to 1:30 p.m.
Leader: Mike Wood
(Reservations required) To reserve, contact Mike Wood at wood-biological@mindspring.com
or 925-899-1282. Hike co-sponsored by California Native Plant Society
and San Francisco Tomorrow
Yerba Buena Island, only a mile and a half offshore, was entirely overlooked
by early botanical explorers. This familiar yet little-known feature of
the San Francisco Bay was placed under military control in 1868 and has
been off-limits to the public for 130 years. As part of the Base Realignment
and Closure Act (BRAC), the Navy began the process of identifying surplus
ands no longer essential for military operations. Mike Wood conducted
a two-year floristic study of the island for the Navy’s base closure
environmental analysis. Join Mike for a circumnavigation of this natural
geologic feature. Remarkable native plants! Astounding views!
Lobos
Creek, The Presidio
Saturday, May 5, 11 a.m.
Leader: Michael Chasse
Hike co-sponsored by California Native Plant Society and San Francisco
Tomorrow
One of the last free-flowing creeks in San Francisco, Lobos Creek serves
as a drinking water source for the Presidio. As such, the public is generally
not allowed access to the creek. Here’s your chance to go
“inside the fence” and explore the oak and willow riparian
wonderland of Lobos Creek! Participants will enjoy the creekside vegetation
such as horsetails, bulrushes, and one of the few San Francisco occurrences
of western goldenrod (Euthamia occidentalis). Efforts to diversify the
coast live oak and arroyo willow riparian understory will also be highlighted.
Time permitting, the group will also explore the restored dune scrub habitat
adjacent to the creek. Meet at the Lobos Creek Valley boardwalk trailhead,
near the El Camino Del Mar/25th Avenue entrance to the Presidio. The trailhead
is at the southwest corner of the parking lot, which is to the east of
Lincoln Boulevard. To RSVP, call Michael Chasse, National Park Service
at 415-561-4457.
TREES: Despite Our Good Intentions
Dear SFT Newsletter Editor:
In the January newsletter, you purport to portray "two sides"
of an issue--when the articles you juxtapose have almost nothing to do
with each other. The reason I am writing is because there is a clear implication
that I am opposed to planting street trees. I have been a friend and supporter
of Friends of the Urban Forest from its beginning in 1981, and I continue
to be a financial contributor as well as member. I want more street trees,
not fewer, but I want them for their amenity value, not their climate-changing
abilities, which are non-existent.

Plastic Bag Reduction Ordinance
It’s called the Plastic Bag Reduction Ordinance but it’s really
a mandate to the major grocery chains that their stores in San Francisco
should provide compostable
plastic bags that could go into the green cans with or without kitchen
scraps or garden waste. The measure was introduced by Supervisors Mirkarimi,
Ammiano, McGoldrick, Daly, Sandoval and Peskin. It would require the use
of compostable plastic and/or recyclable paper checkout bags by grocery
stores located in the City and County of San Francisco. Public hearings
on the measure will be held as early as March 2007.
Goodbye Fat Fluorescent Tubes
Mayor Newsom recently announced that he has asked the City Attorney to
draft legislation banning the use of old-style fluorescent tubes in San
Francisco’s commercial buildings. The old fluorescent tubes, known
as T-12’s, were at one time the standard for energy efficient lighting.
The lighting industry, however, has made significant technological advances
over the past decade, and new model fluorescent tubes are much more efficient,
and save users energy and money. While many businesses in the city have
switched already to the slimmer, more efficient T-8 fluorescent tubes,
the legislation’s purpose is to make the changes universal in all
of the city’s commercial buildings.
San Francisco has greenhouse gas reduction goals of 20 percent below 1990
levels by 2012. The Department of the Environment estimates that if the
remaining T-12s in the city were replaced by the new T-8s, it would save
enough energy to power 7,200 San Francisco residences. Emissions savings
would total 16,500 tons of CO2, the equivalent of taking 3,000 cars off
the road. Contact the city’s current Energy Watch program, a partnership
with PG&E, at 415-554-6131.
The Latest: green weapons
straight from the BBC and the Times of London
One of the world's biggest arms manufacturers, British Aerospace, is investing
heavily in eco-friendly weapons. Soldiers and civilians may now be blown
up by a recyclable explosive, hit by a reduced-toxin rocket, or bombed
by a fuel-efficient fighter jet. Biodegradable land mines and their victims
both turn into compost over time. Quieter warheads reduce noise pollution,
less smoky grenades reduce air pollution, and reduced-lead bullets, if
left in the environment, "do not cause any additional harm,"
says Deborah Allen, director of corporate social responsibility at British
Aerospace. Meanwhile, British troops will stay safe in their armored vehicles
-- hybrid, naturally. "No company, regardless of what they make,
can now just make a product, bung it out there, and then forget about
it," says Allen. "We all have a duty of care to ensure that
from cradle to grave products are being used appropriately and do not
do lasting harm."
Survey shows support for Car free Saturdays in
Golden Gate Park
The City’s Parking and Traffic Department sent 30 workers out two
weekends in August to count cars and pedestrians and to interview park
visitors about the impacts of road closure of JFK Drive in Golden Gate
Park. Just now released, this exhaustive study found that over twice as
many people visit the Park on Sunday as Saturday and are twice as likely
to visit the Museum on Sunday. Driving visitors also found it easier to
Park on Sunday, most finding parking in less then five minutes. The survey
also found very few, surveyed on Saturday, who felt Sunday Closure a discouragement
to visiting the park while over 1/3 of those surveyed on Sunday said it
was why they were there. The entire survey is posted at: http://www.cora.org/JFKAnalysis.pdf
Call your Supervisor and tell them it’s time for Healthy Saturdays.
Governor Arnold Schwarzenegger postponed a High Speed Rail bond vote scheduled
for 2004 and again for 2006 and he now wants to cancel the vote in 2008.
Quick trips from downtown Los Angeles to downtown San Francisco by High
Speed Rail is the best way to relieve highway and airport congestion.
Ask the Governor and Legislature to keep High Speed Rail on the 2008 ballot:
