RE:  SHIFT CENTRAL SUBWAY FUNDS TO TRANSFORM CITYWIDE PUBLIC TRANSIT (SFCTA March 30, 2010 Agenda Items for Central Subway Funding)
ATTACHED:  DRAWING OF CENTRAL SUBWAY

Even in the best economic times, bad transit projects drain funds from beneficial projects, which help more riders often at much lower costs.  But political forces are daunting, with political deals, strong public relations campaigns, pressure from powerful special interest groups and the self-interests of city agencies for staff funding.  Unfortunately, citywide Muni riders have the least influence.

In early March, the Save Muni Summit, with 120 attendees representing 60 neighborhood/ transit advocacy groups began a dialogue for innovative Muni ideas.  Opinions vary widely, but multi-year budget deficits have created a paradigm shift---TO SAVE MUNI NOW.   It will take some bravery, but the Transportation Authority can take an aggressive look at expenditures and funding---TO HELP MUNI NOW.  One major source of funding is the shifting of funds from the Central Subway---redirected not only to maintain existing transit services but to begin strengthening Muni citywide.

Even if more Local, State and Federal funds become available, funds are much more needed to fix and transform the existing Muni System.

If operating budgets fall or stagnate, Muni drivers/ employees lose wages, benefits and wage increases---even as funds are diverted to the short 1.7 mile Central Subway.

All current and new funding should fix the existing system and add transit benefits citywide.

2.  The following three items all regard whales, so I clump them together

hi, jake,
  Ive been writing for two web news services -- the daily climate and environmental health news.  Here's a link to a story on gray whales and arctic climate change that came out this week.  Hope the readers of your excellent newsletter would be interested.      regards, jane kay


Thanks, Jane.  Good to hear from you again.  I see the photos were by Jared Blumenfeld.

yes, jared blumenfeld, is a great fotog. he was there on the trip with his spouse and two children. don't know if you recall but in 2000, the then hearst-owned san francisco examiner ran my magazine story on the victorious fight to save san ignacio lagoon from a salt works plant backed by mitsubishi and the mexican government. the win was the result of a massive boycott in california and beyond against mitsubishi. jared, who was then with international fund for animal
welfare, took the shot used on the cover of bobby kennedy jr. touching a whale. this san ignacio visit over march 2 was a 10th anniversary return to the lagoon, the people and the gray whales. i timed my research for the arctic climate story to coincide with that trip.
thanks for your interest, jake. you're the best voice around.

There is currently a proposal to the International Whaling Commission to allow the resumption of whaling.  In particular the proposal, supported by the Obama Administration, is to allow the killing of up to 140 Grays per year, this in spite of the fact that the California Gray Whales are in trouble.  For the fourth year in a row, their numbers appear to be way down.  This year the counts in San Ignacio Lagoon and Magdalena Bay were very low with almost no cow/calf pairs. NMFS, as a result of pressure, is in the process of completing a population count of the grays which we believe will prove the species is in trouble.  However, NMFS will not release that data prior to the meeting of the IWC. We are planning a series of demonstrations  to oppose this and to ask that Jane Lubchenco, head of NOAA, instruct the US delegation to seek a moratorium on any killing of Gray Whales until current population figures are known.  We are planning demonstrations these for April 20th, just prior to Earth Day, hopefully in every coastal county in the State.  April 20th will be the “SAVE THE WHALES (AGAIN) DAY”.    I am looking for someone in San Mateo  to take the lead on putting a demonstration together.  The Gray Whale Coalition will be helping with the PR and I will work with whomever is willing to do this to get email lists to people to get the word out and to line up speakers for the event.  The lead person in each county would need to find a location and work with me to help get attendance  and speakers to the demonstration.  If you care about the whales and can help me please let me know ASAP.  We don’t have much time to put something like this together but with your help I think we can save the whales.  Contact:  lwan22350@aol.com

The carbon footprint of industrial whaling
Science News 27 March 2010

PORTLAND, Ore. — During the 20th century, industrial whaling activities depleted a storehouse of carbon equivalent to the forests of New England, a new study suggests.
Whales, a group of mammals that includes the largest animals ever to live, are huge repositories of carbon. Individual whales pack on carbon as they grow, typically increasing in weight between 1 and 3 percent each year. In addition to their great heft — a blue whale can weigh around 90 metric tons — whales can store carbon in biomass for well over a century. “In marine ecosystems, whales are like forests,” said Andrew J. Pershing, a biological oceanographer at the University of Maine in Orono. He presented his research February 25 at the American Geophysical Union’s Ocean Sciences meeting.
Industrial whaling — the use of large engine-driven ships to efficiently harvest whales — commenced in earnest around 1900, Pershing noted. That year, he estimates, the oceans held about 110 million metric tons of whales.
Over the course of the 20th century, whaling transferred more than 105 million tons of carbon from living whales into the atmosphere — an amount that equates to about 385 million metric tons of planet-warming carbon dioxide.
Those emissions are small potatoes compared to the approximately 7 billion tons of CO2 emitted by human activities each year. “Whaling did not cause global warming,” Pershing said.
Nevertheless, Pershing noted, the carbon footprint of last century’s industrial whaling is equivalent to that produced by driving 128,000 Hummers for 100 years, or by burning 130,000 square kilometers of temperate forest — an area equivalent to all the forests in New England.

Sea of plastics
Patches of tiny polymer fragments more common and deeper than previously recognized
PORTLAND, Ore. — Recent studies show that the oceans may hold more “garbage patches” of fine plastic flotsam than scientists realized and that the fragments extend well below the sea surface.
Most of these items are the size of fingernail clippings or smaller. They are the wave-shattered remnants of items such as rubbish, abandoned fishing gear and floats from fishing nets and scientific instruments. These plastic bits are especially common in a region of the Pacific Ocean southwest of California that is sometimes called the Great Pacific Garbage Patch.
Recent cruises reveal that there’s more garbage in this patch than often meets the eye, oceanographer Giora Proskurowski of the Sea Education Association in Woods Hole, Mass., reported February 24 at the American Geophysical Union’s Ocean Sciences meeting.
Scientists often tow fine mesh nets behind their boats to conduct a census of floating debris, Proskurowski said. But if researchers tow their nets just at the surface, especially on windy days, they’re likely finding only a fraction of the debris that’s actually present.
On a calm day, debris floats to the ocean’s surface and is readily collected there. But when winds roil the seas, the team’s data show, wave action could briefly send items that are barely buoyant, such as tiny bits of plastic, down as much as 20 meters below the surface. Even during a light breeze, when the ocean’s surface is only dotted with whitecaps, plastic bits can temporarily be deep-sixed, Proskurowski noted.
For example, during one tow — which the researchers conducted when wind speeds were just under 28 kilometers per hour (about 17 miles per hour) — a net towed along the surface caught 431 bits of plastic, while one towed simultaneously at a depth of five meters trapped 240. In similar circumstances, the researchers estimate, the waters between one and 10 meters deep hold as much plastic as the top meter of ocean does.
He and his colleagues collected their data on six cruises through the northwestern portions of the Great Pacific Garbage Patch between June 2004 and July 2009. The researchers estimate that part of that region — a whopping 3.5-million-square-kilometer swath about twice the size of Alaska — contains more than 20,000 bits of floating plastic per square kilometer.
Large swaths of the western North Atlantic also hold prodigious amounts of plastic debris, Kara Lavender Law, who also is an oceanographer at the Sea Education Association, reported at the meeting. On research cruises between the Gulf of Maine and the Caribbean from 1986 through 2008, researchers conducted more than 6,100 surface tows that collected more than 64,000 pieces of plastic, she said.
As in the Pacific, the vast majority of the plastic bits scooped from the North Atlantic were tiny: Analyses of a sample containing about 750 fragments showed that most of these barely buoyant bits were less than a centimeter across and weighed less than 0.15 grams.
About 83 percent of the pieces were collected between the latitudes of 22°N (approximately the latitude of central Cuba), and 38°N (Philadelphia). In general, the highest concentrations of floating plastic occurred in the portion of that area where surface currents converged and flowed at less than two centimeters per second. That area roughly corresponds with the Sargasso Sea, a seaweed-choked region notorious for becalming sailing ships.
Computer simulations reveal that oceanic garbage patches may be more common than even scientists generally recognize, said Nikolai Maximenko, an oceanographer at the University of Hawaii in Manoa. The pattern of ocean currents, chronicled by the movements of scientific instruments set to drift in the world’s oceans, show several large areas in the world’s oceans where currents are slack and garbage could accumulate. “Some of these areas are like a black hole,” he noted at the meeting. “Once things are trapped there, they never escape.”
Two areas particularly suited to trap flotsam are near South America, one west of central Chile and the other stretching from Argentina across the Atlantic nearly to South Africa. But few if any oceanographic cruises have trolled for plastic debris in these two regions — or collected much other data, for that matter. One probable reason, Maximenko noted, is that scientists and fishermen have largely avoided these regions because they aren’t biologically productive.

Creeks, dunes and watersheds: A short history of San Francisco’s waterscape

Urban development has changed the waterscape of San Francisco more dramatically than anywhere else in the state, from a natural creek- and dune-scape to today's modern sewersheds. Christopher Richard of the Oakland Museum will take us on guided photo tour, with historical maps and photographs, uncovering the unique features of San Francisco's primeval waterscape and how the city used and abused the many creeks and lakes as it grew. Richard’s presentation will feature the remaining free-running creeks in San Francisco, which you can visit.

5.  Some readers of this newsletter knew Mel Baker.  His obituary appeared in yesterday's (28/3/10) San Francisco Chronicle

The following sentence from it was a signal trait in his character:  
"He especially enjoyed working with young people, encouraging and helping them find themselves and their place in an often alien and difficult world.  He always judged for himself and did not readily accept another's evaluation of a person or situation."  I respected that independent judgment, even though it sometimes caused me frustration when I wanted to get his participation in a project or convince him of a point of view.  He knew who he was and when I ran up against that surety I learned to stop pressing him.

I owe an important part of my education to him.  He was my supervisor in Strybing Arboretum and from our conversations I gradually found my views on some things shift.  For example, in my naivete I assumed that because discrimination on the basis of race was illegal that that took care of it.  Self-pity was absent in Mel and he never complained about injustice.  However, picking up little glints of information I began to discern on-the-job obstacles he had to contend with that white people didn't--and it was going on right under my nose.  I began to get a glimpse of what the world looked like to black people.  Blatant discrimination, even in politically correct San Francisco.  I began to pay more attention to what was going on around me.  

Later, as he became DPW Assistant Superintendent of the Bureau of Street Cleaning/Urban Forestry, I learned about aspects of city government that gave me insight into the stories I would read about in newspapers.  After he retired, I tried, unsuccessfully, to get him active in a volunteer capacity.  He demurred.  He knew too much about the perdurability of some problems to spend his declining years banging his head against the wall.  Reading about his rich family life in the obituary, I now agree that that is where his time should go.

From Ruth Gravanis:
I was deepy saddened to learn of Mel Baker’s passing.  As the executive director at Friends of the Urban Forest (in its early years--around 1981--JS) for a couple of years while Mel was with the Bureau of Urban Forestry, I don’t know that I could have survived without his help.  Several times he went beyond the call of duty to “save the day” when the soil delivery was late or we didn’t have enough tree stakes or someone broke a gas pipe with a shovel.  And he always was ready with encouragement, sage advice and moral support.

I feel privileged to have known this true civil servant and friend.  Mel’s generosity, calm demeanor, reassuring words and warm smile will not be forgotten.

Frogs: Weed killer creates real Mr. Moms
Hormonal tinkering may explain a host of adverse changes

Two studies have fingered a potential contributor to the widespread decline of amphibians:  water contaminated with atrazine, a weed killer used widely on corn, cotton, and turf.  In the lab, atrazine fully feminized some male frogs...10% of these males transformed into functional "females" that encouraged the advances of healthy males, and in two cases were found to have produced eggs that hatched into viable young.

More frackin' problems
From Ian Wilson:

Dear Jake, I know that (like many of us) you are somewhat skeptical of the concept of "clean energy", but anyway here's an analysis of "clean energy" investments in 2009.  The BBC news item is based on the Pew report.

"Globally, clean energy investments have increased 230 percent since 2005."
"More than 250 gigawatts of renewable energy generating capacity have been installed around the world, producing six percent of global energy."

In a similar vein, there was a disturbing story on the PBS show NOW on Friday night about the practice of hydraulic fracturing, or "fracking", to extract natural gas in the US. Natural gas has been touted as an intermediate step towards clean energy, but it seems that, like every other fossil fuel, its extraction causes enormous environmental and health problems:

9.  From Dan Murphy:
I wanted to share this e-mail with you because it provides a record for Wrentit at Laguna Honda.  It's really an ideal spot for them, but as much as anyone has tried, we've never heard one there before.  This is pretty significant because the only other spots we know they occur in SF are above Baker Beach, Twin Peaks and on Candlestick Hill.  They were at Lake Merced as recently as the 90s.  This adds considerable significance to the coastal scrub at Laguna Honda because Wrentit is a species that is unlikely to move far from it's point of origin.  It suggests the remote possibility that if a habitat corridor is ever established between this and other local sites some of these isolated populations may link-up .  It might also provide an opportunity for a researcher to band or even radio tag our local Wrentits to see if these remnant populations are truly isolated or if they might move around more than anyone suspects.  Now there's a research project the PUC might consider providing some support for.

16.  Googled:  The End of the World as We Know It, by Ken Auletta

...In Googled, Auletta identifies one crucial characteristic of Sergey Brin and Larry Page, the company's founders.  They don't ask for permission:  they do the thing they want to do, and rely on the fact that people will understand the point of it afterwards.  This goes right back to the earliest days of Google.  Search engines don't actually search the internet itself:  if they did, the net would grind to a halt under the effect of all the searches being made.  What Google does instead is make a copy of the entire internet - everything they can get access to - store it on their own servers, and then index it.  It is this index that Google searches.  In addition, the company keeps a copy of every search made, which in turn speeds up subsequent searches.  The computer power involved is huge.  Google won't reveal the figures, so all we know is that it involves millions of bog-standard PCs cabled together.

Note the key fact:  the basic move in Google's rise to dominance was copying stuff without asking.  Don't ask for permission, and rely on the fact that people will love the results when they see them.

This model has stood the company in very good stead, but it plainly involves an attitude in which innocence and arrogance are emulsified together.  Auletta is very good on this:  the complete sincerity of the Googlers' good intentions, blended with their oblivious indifference to other perspectives.

Google is often written about as a ra-ra success story, but Googled is a surprisingly downbeat book.  Auletta looks at the company in its pomp, and sees problems and threats everywhere....The company's activities in China, and its public agonising about them, made them look as if they put profits above ethics, but wanted to be admired for feeling uncomfortable about the fact.

At the same time, the violation of copyright involved in Google's programme to digitise books has caused a bitter backlash.  That was an example of the no-permission policy going badly wrong, because as Brin told Auletta, if they had asked authors and publishers, "we might not have done the project".  

..."Following Google's business model, would he expect authors to generate their income by selling advertising in their books?  If there was no advance from a publisher, who would pay to cover the writer's travel expenses?  (I made 13 week-long round trips to Google [in California] from New York, rented a car, stayed at hotels, and paid for dinner interviews most nights.)  With no publisher, who would edit the book, and how would they get paid?  Who would pay lawyers to vet it?  Who would hire people to market the book so that all those potential online readers could discover it?  The usually voluble Brin grew quiet, ready to change the subject."

1.  Coastal Erosion Forum Announcement

In Pacifica, as elsewhere along the 1,100 mile coast of California, cliffs crumble and beaches wash away and return.  Almost every year we are reminded that here along the San Mateo coast erosion averages two feet a year.  But the process is not orderly, and dramatic events often occur during El Nino years like the one we have experienced this winter.  Again, we watched with horror and fascination, sympathy and disbelief the efforts to safeguard properties along Esplanade.

On Saturday, March 27, join Pacificans for an exploration of the natural processes and history of the creation and erosion of our section of the magnificent California coast.  At this informative forum, USGS emeritus geologist Monty Hampton will present images of the coast as experienced and documented in Pacifica and other local communities.  A coast resident and specialist in environmental marine geology, Hampton surveyed local coastal cliff retreat for many years as chief scientist for the United States Geological Survey.  He was also involved in preparedness workshops with other scientists and the San Mateo County Office of Emergency Services prior to the 1998 El Nino.

The second part of the forum will highlight recent studies undertaken by Philip Williams and Associates, Ltd for the Pacific Institute.  Pacifican Bob Battalio will consider from the viewpoint of a surfer, environmental hydrologist and civil engineer how our beaches and cliffs may be affected in the future by the same physical processes operating today. 

After a short break, Charles Lester, Senior Deputy Director from the Coastal Commission will discuss the Coastal Act.

The afternoon will close with questions and discussion moderated by Brenda Goeden from BCDC.

Many Pacificans and other coastal residents chose to live beside the ocean in order to regularly experience and admire its beauty and power.   That power has shaped and will continue to shape all our communities along the coast in varying ways.  Our understanding and appreciation of the forces that created the coast can better inform all of us as we make decisions about our future next to the beautiful Pacific Ocean.

2.  What to do: Count the costs
Nature is underpriced, says economist Partha Dasgupta. No one pays the mountainside for the trees it grows or the sea for the fish it provides.
Figuring out the economic values of nature’s services and incorporating them into such indicators may be one way to curb destruction of biodiversity. For without a fair accounting, nature looks like a free lunch, and, Dasgupta says, “If you don’t pay for something, you overuse it.”
To highlight the economic value of nature on a big scale, Dasgupta, of the University of Cambridge in England, is pushing for a nature-inclusive alternative to the Gross Domestic Product as an economic indicator. The GDP reports the total value of human-made goods and services without deductions to reflect losses of capital, especially natural capital. Gross, as opposed to net, is “the rogue word” in Gross Domestic Product, he says.
Dasgupta is now urging nations and the World Bank to monitor another measure that he and others have been refining in recent years. “Comprehensive wealth per capita” adds human and natural assets to tallies of capital, and should provide a much-needed way to see whether growth is sustainable, he argues in the January 12 Philosophical Transactions of the Royal Society B.
Dasgupta compared GDP to his new measure of wealth per capita for five countries and for sub-Saharan Africa from 1970 to 2000 (table omitted here). All the nations averaged annual increases in GDP, and sub-Saharan Africa was slipping only 0.1 percent a year. But when Dasgupta used his wealth indicator, the figures looked different. He incorporated natural resources and human resources. With this measure, sub-Saharan Africa looked even worse than it had based on GDP, and the nations, except China, slipped from the positive into the negative column.
What’s still missing from the new indicator, Dasgupta says, is a calculation for the complete range of services that ecosystems perform. Many more ecosystems need assessment before there’s enough data to include these factors in a wealth analysis.
Edward Barbier of the University of Wyoming in Laramie, who has studied Thailand’s coastal mangroves, is building up some of the information on ecosystem damage and services. Since 1975 an estimated 50 percent or more of the country’s mangroves have been destroyed to make way for shrimp farms along the coast. The tsunami that bashed the coast in December 2004 raised interest in one of the mangroves’ previously underappreciated services — their ability to soften the wallop of incoming waves.
Barbier factored storm protection into a 2007 economic analysis that speaks to land use and restoration choices. He estimated the net returns for shrimp farms at $1,078 to $1,220 per hectare (in 1996 dollars, based on investing for five years and then abandoning the farm). If farmers were required to restore the farms with their acidified, compacted soil so that the mangrove ecosystem could thrive again, shrimp farming wouldn’t be worthwhile. Restoration costs at least $8,812 per hectare, the researchers calculate.
But, Barbier found, a fully functioning mangrove ecosystem would be worth the restoration cost. The value of the mangroves — including the protection they give to larvae in fisheries, products harvested directly from the mangroves and storm protection — added up to at least $10,158 per hectare.

5.  Farallones National Marine Sanctuary Asks Bay Area Boaters: Watch Out for Whales!

Gulf of The Farallones National Marine Sanctuary advises boaters to watch out for and steer clear of whales, which migrate into the San Francisco Bay Area in large numbers during the spring. Gray whales are at a particularly high risk of collisions with vessels, as they often travel near shore and may even wander into the bay itself. San Francisco Bay and Tomales Bay always have a few springtime gray whale visitors.

Whales are in the area year-round, but springtime sees most nearshore gray whales, including females with newborn calves slowly making their way back north from Baja calving grounds. Watch for their blow as they surface, which looks like a puff of smoke, low and bushy. Maintain at least 300 feet distance while paralleling them. Never cut across their path of travel, or separate a whale cow from her calf. For information contact

Springtime Brings Newborn Seal Pups to Farallones Sanctuary

It's spring, and harbor seal pups are being born on Bay Area beaches and sand bars. Gulf of the Farallones National Marine Sanctuary advises beachgoers against interacting with seal pups they may find. Newborn seal pups could suffer permanent harm if they re mistaken for orphans and accidentally separated from their mothers. Mother harbor seals will sometimes leave their pups on the beach while they forage at sea, and will return to reclaim and nurse their pups if left alone. Each year healthy seal pups are separated from their mothers by people who mistake them for orphans. The Farallones sanctuary advises  beachgoers to report suspected orphaned pups to a park ranger, or to call The Marine Mammal Center, 415-289-SEAL (7325). Seals are also federally protected animals under the Marine Mammal Protection Act, and to interfere with one could incur penalties. For information contact

6.  Voyage of the Plastiki - From Ian Wilson:
On Saturday March 20 the Plastiki, a catamaran made from plastic drink bottles, set sail from San Francisco. The Plastiki is heading for Sydney, Australia, and the crew is hoping to draw media attention to The Great Pacific Garbage Patch, the 100 million ton plastic stew in the North Pacific Gyre that is twice the size of Texas. At the same time of course they are also drawing attention to the insanity of the bottled water industry.



For what it's worth, I gave a speech for my speech class on the bottled water business yesterday -- one thing I was surprised to discover was that while SFPUC charges us only 1/3 cent per gallon for our extremely high quality tap water here in San Francisco, the Pepsico corporation is charging $1.50 for a 20 oz. bottle of Aquafina ("purified tap water" from the Fresno reservoir,) which works out to be $9.60 per gallon. In other words three times the price of gas. No wonder Pepsico loves selling bottled water!

(Oooooooh!  Thank you, Ian.

This Pacific Gyre thing is so embarrassing to me as a member of the human race that I can't believe we a) allowed it to happen, b) aren't doing anything about it, and c) are continuing to add to it, as if we can't do anything about it.

Is this the same species that created the Athenian and Roman empires, created grand systems of justice, the plays of Shakespeare, science and the technology and explored the farthest reaches of the universe, and, and....?  Tell me it isn't really happening.)

7.  From High Country News:
Will the greater sage grouse get federal protection under the Endangered Species Act or not?
In a March 5 press conference, Interior Secretary Salazar said that the bird -- whose numbers have declined by 90 percent over the past century -- will not get federal protection. That's in spite of the fact that the feds believe the bird needs protection. Extensive scientific research over the past few years, said Assistant Secretary of the Interior for Fish and Wildlife Tom Strickland, has demonstrated that the grouse "does warrant protection. But we are proposing to not list, because of the need to address higher priority species." 
In other words: The sage grouse needs protection, we just don't have time to deal with it right now.

11.  Going Native Garden Tour - April 18
Are you interested in gardens that are water-wise and low maintenance, attractive to humans as well as birds and butterflies? Visit them on the Bay Area’s 8th annual Going Native Garden Tour on Sunday, April 18, 2010, from 10 a.m. to 4 p.m. This is a free, self-guided tour of home gardens landscaped with California native plants.
This year's tour offers over 65 gardens for viewing - from townhome lots to 1-acre plots, from newly planted gardens to established ones. You won’t have to go far to see one: the gardens are located throughout the Santa Clara Valley and the Peninsula. Visit as many gardens as you like - for inspiration and ideas and for pictures (with owner’s permission). Native plants will be available for purchase at select gardens. Many gardens will feature talks on native plant gardening.
What’s special about California native plants? They are adapted to our soil and climate, and are easy to care for. Many of our native plants are naturally water-wise and drought tolerant. They support a wide variety of wildlife that has co-evolved with them, and their distinctive look and elegant beauty gives your garden a sense of place that is uniquely Californian.

The self-guided tour is open to all. Admission is free; registration is required at www.gngt.org before April 18, 12 noon, or until the tour reaches capacity. Space is limited; register early to ensure a place. For more information, email info@gngt.org.

The tour is organized entirely by volunteers. Volunteers receive a t-shirt with original art and invitations to visit native gardens throughout the year. To volunteer, visit www.gngt.org and click on “Volunteer Registration”. Knowledge of native plant gardening is a plus but not required to volunteer.

12,  Feedback

Gray Brechin:
You are probably right that the crosstown subway is really more to accommodate and encourage more vertical growth than it is to move passengers to Chinatown. Mass transit systems have traditionally been planned and built more to raise real estate values rather than to serve existing customers; those who built the cable cars and streetcars also owned the land into which they headed and used the appreciated values of those lands to pay for infrastructure construction with a lot left over for their own lordly mansions and art. See, e.g., the Huntington Museum in San Marino.   

Of course it is silly to think that it's safe to build high rises of 1000 feet and more in a place as seismically nervous as SF but for more reasons than you might imagine. Despite the lessons of 1906 and 1989, few people consider the likelihood of fires in the increasingly dense downtown area. But the buried creeks and marshes South of Market make liquefaction inevitable there and with it the breakup of the fire mains (again.) I wrote about this in the following article:


I REALLY do not want to be there the next time! 

Jeanne Koelling:
I am appalled by the news that UCSF is apparently reneging on their committment to the community and volunteers regarding the Sutro open space. However, it doesn't surprise me that they apparently have turned their energies and resources elsewhere. As a glaring example of their inattention to the surrounding Mt. Sutro area, about six or seven years ago they failed to repair a leaking water tank (located by one of the trailheads to the Mt. Sutro open space area). According to the gardeners, this was an acknowledged, long-standing leak but nothing was ever done about it. As a result, a really humongous landslide eventually happened across from where the stem cell building is currently being constructed, shutting off Medical Center Way for three or four months, and costing thousands to repair. (Half of the hillside slid onto the road.)
I know the site, and I mentioned it in the article I wrote about the Tasmanian blue gum.  I made the point that you needn't be a geotechnical person to understand the angle of repose--and see that MCW above the stem cell research bldgs is ripe for a land slump.  No leaky hydrant necessary; nature takes care of that.
When I first became aware of the Open Space Management program, I had hopes that UCSF had learned their lesson and would help to maintain and restore this wonderful preserve. I guess my hopes may be in vain. 
To a degree I am sympathetic to large institutions who have large, complex commitments and a concomitant complex bureaucratic structure to enable it to function, albeit slowly and inefficiently.  UCSF must labor under another disability:  Its mission is medical research, so expecting it to know how to manage natural resources is unreasonable.  Fair enough.  But it's had >ten years to start coming to grips with its problems.  It has been presented with a priceless gift of the Sutro Stewards, who donated >20,000 hours of skill and energy.  And how does it treat us?  By kicking us in the teeth.

Dear Jake, I was a member of the ACLU.  I have let it lapse because they supported the Citizens United decision by the Supreme Court which opens the floodgates to unlimited corporate money to support or oppose any candidacy.
I had a problem with my membership money.  I looked up the phone number of the home office in NYC, called it, asked to speak to a membership person, was connected with them, and got the problem solved.  They do not show the phone number on their website but I got it through a Google search.

On a related note, there is a website called gethuman.com that lists phone numbers for large corporations that will bypass their electronic systems and get you a person.  Does not include nonprofits.

18.  Chemical warfare

Plants defend themselves from being eaten to death by producing chemical compounds that repel predators, either killing them, making them sick, or being distasteful.  Usually at least one predator is successful at finding its way around the toxic chemistry of a particular plant, and that plant then becomes the larval host for the predator.  The predator then has often exclusive access to the plant’s chemistry, and all other creatures avoid it.   This is very common in the plant world and accounts for the way nature balances things—the balance of nature. 

Some predators have carried the process a step further and, instead of disposing or neutralizing the toxin, it will incorporate it into its own body, thus protecting it from being eaten by other predators.  A very well-known example is the monarch butterfly and its relation to the very toxic milkweeds, the genus Asclepius.  The monarch caterpillars have been very well protected by these toxins.

I just learned from Liam O’Brien that scrub jays have caught on to the fact that when the caterpillar becomes a butterfly, the toxins are sequestered only in the wings, not its body.  The jay rips the wings off and eats the body!

(An amusing sidelight to this:  When I first started to work in Strybing Arboretum in 1970, the Strybing Arboretum Society's director of education, John Kipping [Ted's brother] had a thriving patch of milkweed in the native garden and excitedly brought a kids class to show them the newly-emerged monarch caterpillars, which were busily chewing holes in the leaves--only to discover that the uninformed but assiduous gardener had sprayed them!

Well, it seems amusing now, anyway.  Not to John at the time.)

How plants protect us
Unmasking the secret power of phytochemicals

Rosemary, the fragrant herb that enlivens roast chicken and other favorites, and turmeric, the mainstay spice of curry dishes, contain powerful natural compounds that, in test tubes, can kill cells of a childhood cancer.  
What’s more, grapes, strawberries, and other familiar fruits—and some vegetables—also have chemicals that can destroy the cells of the cancer, known as “acute lymphoblastic leukemia.”

(A researcher) leads the nutrition-focused research that has resulted in these first-ever findings…which reveal the previously unknown ability of about a half-dozen phytochemicals to stop growth of this type of leukemia.  The findings are of interest to cancer researchers and to nutrition researchers exploring the health benefits of compounds in the world’s edible fruits, vegetables, herbs, and spices.

In related research (a researcher) determined for the first time that some component of table grapes prevented the progression of type 1 diabetes in mice and increased their survival.  That was in contrast to diabetic mice that were not fed grapes.

19.  Six Legs Good

Bugs in the System:  Insects and Their Impact on Human Affairs, by May R. Berenbaum
Found everywhere from the poles to the equator, from sea level to the highest peaks and from deserts to rain forests, insects are all around us. They are extremely abundant: at any time, there are somewhere around 10 quintillIon individual insects on the earth. And they are persistent, having been around for more than 400 million years. It can be argued that insects are the most successful life-form that has ever arisen on this planet. The modem urban dweller might prefer to stay cocooned from direct contact with six-legged creatures, but it would be foolish to ignore them. For every human being alive today, there are more than one billion insects, and we need them more than they need us.
         More than half of all known species, and three quarters of all known animal species, are insects. Small size, a water-proof cuticle, phenomenal powers of reproduction and the power of flight all combine to give “bugs” (a term that, more strictly, refers specifically to insects of the suborder Heteroptera) a considerable edge over other animals. And there are, of course, many more insect species than those to which we have given names. By various reckonings there are anywhere from three to 30 or more unknown species for every one known. So it is with ample justification that May Berenbaum takes a good, hard look at the negative and positive impact of insects on human affairs and demonstrates just how important insects are to our continued existence.
         Bugs In the System begins, not unreasonably, with classification. No, read on—some of this stuff really is fun. Things need names, after all. Thousands of new insect species are described every year; the sheer abundance inevitably makes for a few good stories. While I was aware that romantically inclined entomologists have named new species in honor of sweethearts (a lasting and less embarrassing tribute than a tattoo), I had no idea that a small fly had been given the specific name thanatogratus after the Grateful Dead. I need not explain the etymology of Heerz lukenatcha.
         Chapter after chapter reveals astonishing facts and striking interrelationships between our world and that of insects. Berenbaum skillfully imparts her wide-ranging knowledge and infectious enthusiasm for bugs on every page. When it comes to sex, insects show off some of the more startling instances of political incorrectness in the natural world. Male bedbugs, for instance, have dispensed with the niceties of arthropod foreplay and simply stab their intended through the cuticle with a spike-like penis. And let us not forget the intriguing story of the predatory female firefly who has learned to lure the males of other closely related species to their death by imitating the sexual flashing signal of that species and not her own. It’s a jungle out there.
         Insects contribute to our lives in surprising ways. Even silk aficionados might he startled to learn that what feels so exquisite against the skin is nothing more than insect saliva. Chocoholics can discover how tiny midges play a vital role in the production of their preferred foodstuff. Honey lovers will be pleasantly disgusted to learn that they spread the regurgitated stomach contents of thousands of bees on their breakfast toast. The amount of effort involved in the process is quite remarkable: in order to create one kilogram of honey, worker bees have to visit flowers 10 million times and fly a distance equal to 10 times the earth’s circumference.
         Those hard-working bees are a big part of human business, Berenbaum reminds us. They pollinate just about all the world’s species of flowering plant; without their labors we would lose one third of all we eat. For their part, insects eat almost anything: detritus, carrion, dung, fungi, blood, other insects and, of course, plants, dead or alive. Probably a little under half of all insects are herbivores. Actually, plants are not particularly easy or rich sources of sustenance, but insects have evolved numerous ways of overcoming plant defenses and poor food quality.
         As part-time herbivores ourselves, we often run into a conflict of interests. The way we grow our food only exacerbates the problem; insects have not been slow to cash in on the seemingly endless acres of uniform crops we plant every year. On average, we probably lose around one fifth of all that we grow to munching insect mandibles. Why not get some of our own back and eat them? For those inclined to take the question seriously, Bugs in the System gives us the lowdown on rustling up some grubs. Insect bodies contain decent concentrations of fats, proteins, carbohydrates, vitamins and minerals. The food value of certain species compares more than favorably with—dare I say it?—hamburgers. More than 500 kinds of insect are regularly eaten by people all around the world, so there is no reason not to get your wok down off the shelf and start cooking. After all, most animals on the earth include some insects in their diets. If insects were to vanish, countless thousands of other animal species would go with them.
         No matter how you look at it, insects make ecosystems work. Besides the vital job of pollination, they recycle nutrients, enrich soils and dispose of carcasses and dung. And insects are inextricably wound into human society. In addition to silk and honey, they provide us with waxes, medicines, dyes and other useful products. We use them to convict murderers, to catch fish, to rid us of pest insect species and weeds. We use them as model systems to help us understand the many complexities of biology, from behavior to genetics. 
         There is also the all-too-familiar downside to our buggy companions. Insects are major vectors of animal and plant diseases. Berenbaum shows only too clearly how the ravages of insects have changed the short course of recorded human history. Diseases such as louse-borne typhus have influenced the outcome of wars much more decisively than have weapons. The world has seen three pandemics of plague, the second of which killed one third of the population of Europe.
We are well aware now that plague is caused by a species of bacterium carried by fleas that live on black rats and that bite, among other things, humans. But it was not always so; enlightenment was a long time coming. The first pandemic struck in A.D. 541, and it was not until the early 1900s that the whole picture of plague finally came together. Berenbaum’s text brings history to life. The war against insect-borne diseases is, of course, far from over; several million human beings still die every year as a result.
         In short, this book is a tremendously good read, packed with information that will appeal equally to biologists and laypersons, students and teachers. Each chapter, on such broad topics as insect physiology, behavior and sociality (there is even a chapter entitled “Appreciating insects”), takes the reader on a voyage of discovery and ends with a carefully arranged list of references, inviting further exploration. At the department of zoology here at Oxford, we hold a popular, annual bio-trivia quiz. I have already extracted numerous excellent questions with which to test this year’s participants.
         
Another entomology book? Yes, but one with a difference. If you really don’t like bugs, pick the book up anyway—it might bite you. Newcomers will be fascinated and intrigued. For old hands at the game, this kind of book reminds us why we took up entomology in the first place and still find the subject so engrossing. GEORGE C. MCGAVIN is assislant curator of entomology at the Oxford University Museum and lecturer In zoology  at Trinity College, Oxford.
