NPR: Lead Wars→

“Flint, Mich., isn’t the only American city with a lead problem. Though the health crisis in Flint has highlighted the use of lead in water pipes, author David Rosner tells Fresh Air’s Terry Gross that lead, which is a neurotoxin, can be found throughout the U.S. on walls, in soil and in the air.

”The problem with lead is that it’s now really everywhere, and we’ve created a terribly toxic environment in all sorts of ways,” he says.

Lead is particularly dangerous to young children. In their book, Lead Wars, Rosner and co-author Gerald Markowitz describe the ways in which even small exposures can interfere with a child’s brain development and cause lasting learning challenges.

”It causes IQ loss. It causes behavioral problems. It causes attention deficit disorder, hyperactivity, dyslexia,” Markowitz says.

Rosner adds that even a small amount of lead can have a lasting effect on a child’s health. “As early as the 1910s and 1920s, [doctors] were documenting children who had absorbed lead on their fingers as dust and had put their hands in their mouth and actually began going into convulsions,” he says. “It’s not like you need a lot of it.””

Erica Goode: Non-Native Species Aren’t Always Unwanted→

New York Times:

“Dr. Thompson and other scientists have called for a more nuanced approach to evaluating whether the presence of a species is harmful or beneficial. Eradicating most invasive species is virtually impossible in an era of globalization, they note. And as climate change pushes more species out of their home ranges and into new areas, the number of so-called invaders is likely to multiply exponentially.

Yet the notion that a species should not be judged on its origins is highly controversial, as Mark Davis, a biology professor at Macalester College in Minnesota, discovered when he and 18 other researchers submitted an article in 2011 saying just that in the journal Nature...

But in the five years since that contentious exchange, the idea that invasive species should be assumed guilty until proven innocent has begun to wane, the shift prompted in part, Dr. Davis speculated, by concerns over the use of chemical pesticides and the disruption of landscapes caused by many eradication efforts.”

Carrol Henderson: Ammo Should Not Kill Twice→

Pioneer Press:

“Lead ammo zealots have tarnished the image of hunters as “America’s conservationists.” How? These people continue to use lead ammo after learning lead is causing secondary poisoning of wildlife. They cannot be considered conservationists if they continue to use lead. They say, “We don’t need to be concerned about the loss of eagles and other wildlife from lead poisoning because those losses don’t affect wildlife at a population level.” Next thing you know, deer poachers will claim that they should not be prosecuted because they are not killing enough deer to affect the state’s deer herd at a population level.”

Serious words from a wise man. 

Laura Bliss: Lead Poisoning Politics→

CityLab:

“By the 1920s, lead was an essential part of the middle-class American home. It was in telephones, ice boxes, vacuums, irons, and washing machines; dolls, painted toys, bean bags, baseballs, and fishing lures. Perhaps most perniciously, it was in gasoline, pipes and paint, the building blocks of urbanization and a growing housing stock.

That was precisely how the lead industry wanted their product to be seen. Despite the fact that lead was known to be toxic as early as the late 19th century, manufacturers and trade groups fiercely marketed it as essential to America’s economic growth and consumer ideals, especially when it came to their walls. Latching onto the nation’s post-Depression affection for clean, bright colors, they were successful.

According to a new paper in the Journal of Urban History by David Rosner and Gerald Markowitz, the public health historians and co-authors of The Politics of Science and the Fate of America’s Children, the answer lies at the intersection of politics, class, and race.”

Crimes committed against the American population. And like with the recent banking scandals, no greedy, corporate executives were jailed for their crimes.

Abstract
One of the most troubling urban health issues is childhood poisoning caused by lead, the widespread environmental toxin. It is in old plumbing fixtures, solder, paint and other building materials in huge quantities. Despite decades of improvements in blood lead levels among America’s children, the continuing presence of lead on the walls of the nation’s older houses and the known neurological effects of low-level exposures presents a classic problem: in light of the enormous costs of detoxifying the nation’s housing, should society remove this toxin in order to prevent future impacts on IQ, attention deficits disorders, and possibly criminal behavior, or do we remove some of the most pernicious sources, such as window sashes and chipped paint to reduce, not eliminate, the risk to children? Throughout the 1970s and 1980s this issue emerged among public health advocates, HUD officials and housing reformers, and community organizers and activists. Who should bear the responsibility for polluted housing: Industry, housing officials, public health officials, landlords or tenants? The battles began during the 1960s and continue to today. In 2001 the high court in Maryland condemned studies conducted by Johns Hopkins researchers that sought to develop methods for the partial remediation of homes, saying they were akin to Nazi human experiments in which children were used as human guinea pigs. This article traces the evolving debate over responsibility for the public health consequences of polluted housing.”

David Smith: Architect of the Twin Cities’ Parks: Horace Cleveland→

MinnPost:

MHS

“Horace W. S. Cleveland was a pioneer landscape architect. His greatest achievement was designing a system of parks and parkways in Minneapolis. He advocated preserving spaces for parks in the rapidly growing cities of the American West. Cleveland was especially influential in preserving the banks of the Mississippi River gorge in St. Paul and Minneapolis as parkland.

Cleveland became a landscape architect at a relatively late age. He was forty years old when he went into business as a landscape gardener in Boston, not far from his boyhood home of Lancaster, Massachusetts. Following the Civil War, he moved to New York City, where he worked for America’s most famous landscape architect, Frederick Law Olmsted. Cleveland and Olmsted, who became lifelong friends, both believed that parks are essential to the life of cities.”

Read the short article on the important work Horace Cleveland accomplished for Minneapolis.

“Look forward a century, to the time when the city has a population of a million, and think what will be their wants.”

Josephine Marcotty: Buffer Law Debate→

Star Tribune:

“Only about one-third of the streams in Minnesota’s farming regions will get the maximum amount of protection under new state buffer rules — a number that environmentalists say falls far short of what Gov. Mark Dayton’s signature water protection law was intended to accomplish.

State regulators are drawing up a map of the streams, ditches, wetlands and lakes that will fall under the new and highly controversial buffer law — the nation’s first — enacted last year in an effort to reduce pollution from farm runoff.

But they are relying on a decades-old list that excludes more than half the known small streams that create a web across Minnesota’s landscape and carry sediment, phosphorus and other pollutants into the major rivers.”

Past regulatory approaches have failed in agricultural areas because people do not comply. As maps are created, both sides complain. What is public water? Common sense says it is all water is public water, but statute and rules each have definitions. In the legal world, words have meaning and consequences. All air is public, should all water be public? We need buffer laws that are meaningful and enforced. In addition, other approaches need to be adopted. For example, if you pollute you should pay. This approach is reasonable as well -- perhaps a mix of approaches will result in a system that produces clean water. 

Nicholas Kristof: America is Flint→

New York Times:

“WE have been rightfully outraged by the lead poisoning of children in Flint, Mich. — an outrage that one health expert called “state-sponsored child abuse.”“We are indeed all Flint,” says Dr. Philip Landrigan, a professor of preventive medicine at the Icahn School of Medicine at Mount Sinai. “Lead poisoning continues to be a silent epidemic in the United States.”

But lead poisoning goes far beyond Flint, and in many parts of America seems to be even worse.

“Lead in Flint is the tip of the iceberg,” notes Dr. Richard J. Jackson, former director of the National Center for Environmental Health at the Centers for Disease Control and Prevention. “Flint is a teachable moment for America.”

In Flint, 4.9 percent of children tested for lead turned out to have elevated levels. That’s inexcusable. But in 2014 in New York State outside of New York City, the figure was 6.7 percent. In Pennsylvania, 8.5 percent. On the west side of Detroit, one-fifth of the children tested in 2014 had lead poisoning. In Iowa for 2012, the most recent year available, an astonishing 32 percent of children tested had elevated lead levels. (I calculated most of these numbers from C.D.C. data.)

Across America, 535,000 children ages 1 through 5 suffer lead poisoning, by C.D.C. estimates.”

Lead is in our sports equipment: lead fishing tackle and lead bullets. Where does that lead end up? It has been estimated that 200 loons die each year in Minnesota due to ingestion of toxic fishing tackle. Hunters and their kids ingest lead from game killed with lead bullets, thereby lowering their IQ for the right to use cheaper toxic ammunition when copper bullets are better and nontoxic. Industry threatens governments attempting to regulate lead in these products, as they profit from degraded environments and brain-damaged customers. Gold Bless America! Profit over People! 

Governor Dayton Backs Off Buffers for Private Ditches→

MPR:

“Gov. Mark Dayton’s aggressive plans to boost water quality by requiring buffer strips along Minnesota waterways took a step back Friday when the governor acknowledged he’s ordered state conservation officials to stop mapping “private ditches.”

Dayton’s made water quality and buffer strips a key part of his intended legacy in his last years in office. The Legislature last year backed a scaled down effort to require the buffers. While there was consensus on the plan for public waterways, farmers and farm groups remained concerned about the law’s intentions when it came to ditches on private land.

The new law requires strips on ditches in areas that would benefit public waterways, but farm groups say private ditches were never meant to be part of the deal.

On Friday, Dayton said he pulled back on the private ditch efforts and ordered the Minnesota Department of Natural Resources to stop mapping them after Republicans threatened to torpedo water quality projects Dayton’s seeking in a public works spending bill in the coming session.”

Nathaniel Rich: DuPont's Sin and Rob Bilott's Courage→

New York Times:

“Just months before Rob Bilott made partner at Taft Stettinius & Hollister, he received a call on his direct line from a cattle farmer. The farmer, Wilbur Tennant of Parkersburg, W.Va., said that his cows were dying left and right. He believed that the DuPont chemical company, which until recently operated a site in Parkersburg that is more than 35 times the size of the Pentagon, was responsible. Tennant had tried to seek help locally, he said, but DuPont just about owned the entire town. He had been spurned not only by Parkersburg’s lawyers but also by its politicians, journalists, doctors and veterinarians. The farmer was angry and spoke in a heavy Appalachian accent. Bilott struggled to make sense of everything he was saying. He might have hung up had Tennant not blurted out the name of Bilott’s grandmother, Alma Holland White.

White had lived in Vienna, a northern suburb of Parkersburg, and as a child, Bilott often visited her in the summers. In 1973 she brought him to the cattle farm belonging to the Tennants’ neighbors, the Grahams, with whom White was friendly. Bilott spent the weekend riding horses, milking cows and watching Secretariat win the Triple Crown on TV. He was 7 years old. The visit to the Grahams’ farm was one of his happiest childhood memories.

When the Grahams heard in 1998 that Wilbur Tennant was looking for legal help, they remembered Bilott, White’s grandson, who had grown up to become an environmental lawyer. They did not understand, however, that Bilott was not the right kind of environmental lawyer. He did not represent plaintiffs or private citizens. Like the other 200 lawyers at Taft, a firm founded in 1885 and tied historically to the family of President William Howard Taft, Bilott worked almost exclusively for large corporate clients. His specialty was defending chemical companies. Several times, Bilott had even worked on cases with DuPont lawyers. Nevertheless, as a favor to his grandmother, he agreed to meet the farmer. ‘‘It just felt like the right thing to do,’’ he says today. ‘‘I felt a connection to those folks.’’”

Natalie Wolchover: Longer Time to Recover is a Warning Sign→

Atlantic:

“Systems that exhibit such “critical transitions” tend to be so complicated and riddled with feedback loops that experts cannot hope to calculate in advance where their tipping points lie—or how much additional tampering they can withstand before snapping irrevocably into a new state.

At Peter Lake, though, Carpenter and his team saw the critical transition coming. Rowing from trap to trap counting wriggling minnows and harvesting other data every day for three summers, the researchers captured the first field evidence of an early-warning signal that is theorized to arise in many complex systems as they drift toward their unknown points of no return.

The signal, a phenomenon called “critical slowing down,” is a lengthening of the time that a system takes to recover from small disturbances, such as a disease that reduces the minnow population, in the vicinity of a critical transition. It occurs because a system’s internal stabilizing forces—whatever they might be—become weaker near the point at which they suddenly propel the system toward a different state.”

Cheryl Katz: Big Northern Lake on Thin Ice→

Yale 360:

“As temperatures rise, the world’s iconic northern lakes are undergoing major changes that include swiftly warming waters, diminished ice cover, and outbreaks of harmful algae. Now, a global consortium of scientists is trying to assess the toll.

Baikal is just one of many large lakes worldwide showing signs of rapid change as a result of rising temperatures. Majestic water bodies like Baikal and North America’s Lake Superior are integral to regions such as Siberia and the Great Lakes, playing a key role in transport, fisheries, and tourism. They also store the bulk of our planet’s liquid freshwater. But the lake-rich northern latitudes, where the majority of these vital resources lie, are the fastest-warming regions on earth.

More than three in four large lakes above the 40th parallel north, roughly the latitude of New York City and Madrid, have undergone summer surface temperature increases of 2.7 F or higher from 1985 to 2009, a new international research collaboration finds. Some lake temperatures rose more than twice that amount. Nearly all have experienced retreating winter ice, a loss that can interfere with internal circulation, reduce oxygen, and help create fertile breeding grounds for harmful algae. These changes, which appear to be accelerating, have potentially profound consequences for water supply, food, and aquatic life. ”

John Myers: Lakes Warming Up

Duluth News Tribune:

“Lakes across the globe are warming faster than oceans and air temperatures in a sign that climate change may be affecting freshwater environments more than anyone had previously understood.

That’s the finding of a report published in the journal Geophysical Research Letters and announced Wednesday at the fall meeting of the American Geophysical Union. The study found lakes worldwide warmed an average of 0.61 degrees Fahrenheit per decade between 1985 and 2009.

In northern climates, that increase averaged 1.3 degrees per decade. “The world’s deepest ice-covered lakes warmed twice as fast as the overlying air temperatures,” the report notes.

Temperature is among the most basic factors in lake ecosystems, the study’s authors noted, and when “the temperature swings quickly and widely from the norm, life-forms in a lake can change dramatically and even disappear.””

How long will some people keep their head in the sand? Justice would be served if only those descendants of today's global warming deniers paid the costs of inaction.

Peter Callaghan: Chuck Marohn's Mission→

MinnPost:

“Marohn created a blog (strongtowns.org) to share his observations about land use, sprawl and how to make existing communities economically stronger. One of the early posts was titled “Confessions of a Recovering Engineer.” He is not particularly popular among his former colleagues.

“I am a guy who started out writing a blog and felt like I was a voice in the wilderness with maybe some crazy ideas that people around here certainly weren’t buying,” Marohn said. “What I found is there’s a nation of people hungry to do something different, share our message and support us.”

“Us” is Strong Towns, the nonprofit that grew out of Marohn’s blog and that now has a small-but-growing national membership. As part of his work for Strong Towns, Marohn publishes frequent blog items, records podcasts and travels (a lot) — he’s spent 64 nights on the road so far this year — delivering “Curbside Chats” to groups and working with cities. He had just returned from taking part in a White House conference on rural placemaking.”

I encourage you to catch one of Chuck's Curbside Chats. Several issues resonated with me. First, suburban development is insufficient dense to support infrastructure replacement costs at current tax rates. Suburban development is subsidized or the replacement costs are supported by ever more subdivisions. Chuck notes the latter fact and calls out suburban development as a Ponzi scheme. Second, communities should build roads and streets, not stroads. Stroads are hybrids that are dangerous for people, that also reduce economic value of the surrounding lands. Third, governments are deaf or ignorant on these issues. We (citizens) need to confront officials to demand better designed streets and require development patterns with higher density potentials. We also need to take small positive actions in our neighborhoods to produce safe streets and educate community leaders on the importance of economically sustainable development. We need to build areas with Strong Town Principles.

Peter Harnik: Need for Parks→

ULI's UrbanLand:

“While a number of big-city mayors and even a governor have endorsed the goal of providing parks or other open spaces within a ten-minute walk of residents, adding enough parks to serve all 249 million people living in U.S. cities, suburbs, and urbanized areas—83 percent of the population—will be a challenge.

There is another, concurrent approach to providing Americans with a nearby park: bringing more dwellings to the periphery of existing parks to increase density on their edges. This is what TPL researcher Kyle Barnhart calls, “not only ‘parks for people,’ but also ‘people for the parks.’”

The concept is parallel to the approach taken with transit. It is well established that the expense of building and operating transit lines can and should be earned back through the promotion of transit-oriented development—dense pockets of housing, commercial space, and retail development within 2,000 feet (610 m) of subway stations and major trolley and bus stops. Arlington, Virginia, for example, has won numerous awards—and achieved notable economic success—by closely tying compact residential and commercial redevelopment to six of its Metro stations.

The same logic can hold for park-oriented development. While studies by Smart Growth America and others show that transit is the strongest generator of demand for urban consolidation and density, parks can be high on that list, too. This has been shown in compact redevelopment in such places as Philadelphia (around Hawthorne Park), St. Paul, Minnesota (around Wacouta Commons), and Denver (along Commons and Confluence parks).”

Alana Semuels: Highway Teardown Opportunities→

The Atlantic:

“As some of the highways reach the end of their useful life, cities and counties are debating the idea of tearing down urban freeways and replacing them with boulevards, streets, and new neighborhoods. Though it might sound like a headache, tearing down freeways in city centers can reduce air pollution and create parks and public spaces that bring cities together, according to Shelton.

“The removal of urban interstates is a growing trend in the U.S.,” Shelton and Gann wrote. This trend, if carried to its logical extreme, can yield sites of intervention that hold the promise of remaking the American city.””

It is important for citizens to consider and debate the merits of highway deconstruction. Often it may be the best option for a community.

Jason G. Goldman: Extinction Happens on the Margins→

Conservation:

“Keil and his team noted that habitats can be lost in different spatial or geometrical patterns. Is extinction more likely if habitats are lost from the edge of a landscape toward the center or if they’re lost starting from the center? What if habitat loss is not quite so orderly, but more random? To find out, the researchers created four theoretical models that combined the geometry of habitat loss with species extinction, then compared them to bird, mammal, and amphibian distributions in nine real world regions to see which was most useful at predicting the impacts of habitat loss...

Of greater importance to those who aren’t just biogeography theory wonks, the researchers also discovered that extinctions are more likely to occur when landscapes are destroyed from the outside edge towards the center (such as in sea level rise) than if habitats are lost in the reverse direction (such as in urban sprawl). And the geometrical direction of habitat loss actually played a stronger role in determining the loss of species richness than the overall area lost. In other words, a little habitat loss on the edge of a region was worse for biodiversity than more habitat loss towards the center.”

Casey Jaywork: Anatomy of a NIMBY→

Seattle News:

“The language is apocalyptic; the tone, desperate. “Cancer,” “canyons of darkness,” “anguish, hopelessness, and loss.”

But these aren’t war-zone dispatches, nor recollections of a natural disaster. They’re public comments from a Seattle City Council’s land-use-committee hearing held earlier this year. It was there that aggrieved homeowners walked up to one of two smooth wooden podiums in City Hall’s Council chambers to vent the vexation they felt as they watched their communities “being torn apart” by development, as Capitol Hill resident the Venerable Dhammadinna put it.

“Elderly homeowners, the gay community, older women, and families are no longer welcome,” she told the Council, referring to the city’s mixed-density residential areas. “Our neighborhoods are shadowed by tall, bulky buildings. Gardens are being cemented, trees cut down. Those who can’t carry their bags of groceries up and down the hills are not invited into this dystopia.”

The testimony was so consistent—or redundant, depending on your position—that a drinking game could have been fashioned from the proceedings: Take one shot whenever someone said “neighborhood character,” two for “transient.””

An interesting article of Seattle redevelopment dynamics and politics. I was struck by the sameness of the issues across many places.

Matt Steele: Use Cost:Benefit Analysis to Select Transit Routes→

streets.mn

“As the Twin Cities proceeds with plans to build over three billion dollars worth of rail extensions for the Blue and Green Lines, many transit advocates question if we’re missing an opportunity for transformative projects that lift up urban neighborhoods on their routes between suburban park & rides and the downtown core...

It comes down to this: Let’s discuss costs and benefits in parallel until shovels hit the ground, rather than committing to a “value” alignment and then being all ¯\_(ツ)_/¯ when the cost goes up 50% or more. For things like tunnels under parks and bridges over the Grimes Pond which are being planned precisely because these low-development corridors were supposedly going to make the chosen alignment more cost effective. If we’re going to build viaducts and tunnels, let’s at least do it in a way that brings stations to the doorsteps of tens of thousands more transit riders.”

“Using a tool similar to a computer game, Melissa Motew is peering into the future. Motew is a modeler. She uses computers and mathematics to simulate ecosystems and make sense of nature.

T.R. Goldman: A Subdivision that Reduced Car-Dependency→

POLITICO:

“Evanston was failing as a suburb, so it reinvented itself as a mini city. Now the city of Chicago wants to follow its lead.

At first glance, downtown Evanston, Illinois, doesn’t look revolutionary—just another gentrifying urban core with the obligatory Whole Foods, the local organic sustainable restaurants serving $14 cocktails, the towering new, high-end luxury apartments filled with stainless steel appliances and granite countertops. The booming downtown feels increasingly hip; this summer it was featured as a “Surfacing” destination in the New York Times Travel Section. “I have everything here,” says Joanne McCall, pausing one evening on her way inside Sherman Plaza, a soaring, 26-story condominium building. “The post office, the dry cleaner, the movies, I work out upstairs, the Whole Foods is over there, the hair dresser over here. And the Uber thing is getting big here.”

It takes, in fact, a few extra minutes in the neighborhood to realize what’s different—and what’s missing. Downtown Evanston—a sturdy, tree-lined Victorian city wedged neatly between Lake Michigan and Chicago’s northern border—is missing cars. Or, more accurately, it’s missing a lot of cars. Thanks to concerted planning, these new developments are rising within a 10-minute walk of two rail lines and half-a-dozen bus routes. The local automobile ownership rate is nearly half that of the surrounding area.”

A thorough article on how a city was redesigned for the benefit of citizens rather than for box stores. The article speaks of transit-oriented development, and it should be noted that the term meant mass transit, less car parking spaces, allowance of beneficial high density, and a major zoning ordinance change allowing mixed use and a focus on public benefits,
