The Itasca forest during the late nineteenth century contained towering pines and numerous lakes. Individuals like surveyor Jacob Brower became captivated by the region and the wildlife that inhabited it. They recognized that the economic potential of northern Minnesota would change its landscape. Their effort to preserve Lake Itasca led them to contend with the lumber industry, public interests, and the politics that weaved between them.

People have long appreciated Lake Itasca’s beauty and resources. Some eight thousand years ago indigenous hunters left spears at a bison kill site in the area. Around 1200 CE the Blackduck people created a village there, eventually leaving remnants of their unique pottery behind. Ojibwe groups have lived in the lake’s vicinity since the 1700s.

The U.S. government slowly began turning their attention to the region after buying Louisiana Territory from France in 1803. In 1832 the Ojibwe leader Ozaawindib brought Henry Schoolcraft to Omushkos Lake and the Mississippi headwaters. Schoolcraft renamed the lake Itasca by combining the Latin words veritas (truth) and caput (head).

On many long journeys have I gone. And waited, too, for others to return from journeys of their own. Some return; some are broken; some come back so different only their names remain. Be brave, Lake Itasca go you must.

Pavement Science

“There are two types of pavement, concrete and asphalt, and these industries compete with each other,” explained Lev Khazanovich, an engineering professor at the University of Minnesota. “Each is always trying to improve their product, and so asphalt and concrete in Minnesota are much better than what was built 30, 40 years ago.”

The difference between the two pavements comes down to cost and lifespan. Concrete is harder and more durable, but asphalt is cheaper. In fact, considered philosophically, these two technologies might even be diametrical opposites.

“Fundamentally, asphalt is a mechanical compaction of the paving products,” Steve Lund explained to me. “It’s a physical compaction and pressing, whereas on the concrete side it’s more of a chemical reaction and hardening of the paving product.”

Concrete is composed of water, aggregate and cement (with occasional other kinds of material, such as coal ash from coal power plant filters). The chemical reaction between cement and water causes it to harden. It can thus be molded, like plastic, into a seemingly infinite variety of shapes. Asphalt, on the other hand, is a form of petroleum mixed with aggregate (mostly sand and gravel), heated up and then pressed down to form our roads, bike paths and parking lots...

“There are several different types of pervious concrete,” explained Nathan Campeau, another engineer at Barr. “It has been around for quite a while now, 10 to 12 years, and installed in several locations around the state. And there’s a corollary in porous asphalt, special mixes that have a lot of void spaces in them. They’re basically like a sponge, and allow water to go from the surface down to the sub-grade below the pavement.”

While the benefits of new pervious pavements are clear, they also present technological challenges. First, it can be tricky to install them, and they require specific equipment and time-consuming construction processes. Many contractors struggle with pervious technologies when using them for the first time.

Second, cities like Shoreview have to carefully maintain their pervious pavements, so that sediment and grit does not clog up its “void spaces.” To do this, cities and property owners have to actually vacuum the sediment out of their pervious roads and parking lots.

Use pervious surfaces, we must. They are our city rainwater management  hope.

Mercury Levels in the Environment

The most comprehensive estimate of mercury released into the environment is putting a new spotlight on the potent neurotoxin. By accounting for mercury in consumer products, such as thermostats, and released by industrial processes, the calculations more than double previous tallies of the amount of mercury that has entered the environment since 1850. The analysis also reveals a previously unknown spike in mercury emissions during the 1970s.

The finding doesn’t indicate a greater risk to human health; scientists already know how much mercury most people are exposed to. But it does show how tighter regulations over the past 4 decades have lowered the total amount of mercury emitted to the global environment—even as some industries in the developing world continue to expand.

When you use mercury, careful you must be. For the mercury poisons back.”

Poverty Moving to the Suburbs

You might be wondering why poor families are moving to the suburbs in large numbers—the number of suburban poor grew more than twice as quickly as the number of urban poor between 2000 and 2011—if they are such hard places for poor people to get ahead. Part of it is that as middle- and high-income households moved to the suburbs, the low-wage workers who look after their children had little choice but to follow. Then there is the fact that as America’s most productive cities experience a revival, gentrification is displacing low-income families to outlying neighborhoods and towns.

Before we can understand what makes some suburbs so miserable, we first have to understand what makes others succeed. The most successful suburban neighborhoods fall into two categories. First, there are the dense and walkable ones that, like the most successful urban neighborhoods, have town centers that give local residents easy access to retail and employment opportunities. These neighborhoods generally include a mix of single-family homes and apartment buildings, which allows for different kinds of families and adults at different stages of life to share in the same local amenities. The problem with these urban suburbs, as Christopher Leinberger recounts in his 2009 book The Option of Urbanism, is that there are so few of them, and this scarcity fuels the same kind of gentrification that is driving poor people out of successful cities.

Density matters, ... Look at the suburbs. Judge them by walkability, do you? Save them you can't. 

Experts Review State's efforts on Wild Rice and Sulfates

For two days, the experts picked through three years’ worth of data from Minnesota Pollution Control Agency’s lab and field studies, dispensing both praise and criticism for the agency.

The reason for the MPCA studies: The Minnesota Chamber of Commerce, representing mining and other industries, is challenging the state’s current limit of 10 milligrams per liter of sulfate in wild rice waters. Wastewater flowing from taconite mines and wastewater treatment plants boosts the level of sulfate in some rivers and lakes far higher than the limit, especially in northeastern Minnesota, and the Legislature has charged the Minnesota Pollution Control Agency with figuring out whether the standard needs to be changed.

MPCA’s efforts included laboratory experiments and field surveys, all of which the agency presented to the independent scientists for review, a standard practice in scientific endeavors....

Shannon Lotthammer, the MPCA staffer in charge of shepherding the process, said she was pleased with the guidance from the reviewers. Agency staffers knew the analysis was not complete, but wanted to get input from the independent scientists before they got further along in the process. A recommendation on whether the standard should be changed is expected by the end of the year.

In a dark place we find ourselves related to mining, and a little more knowledge lights our way. Difficult to see the long-term consequences of our exploitation of minerals. Always in motion is the future.

Polluters Don't Pay

Chad Selweski, reporting for The Macomb Daily:

Two days after Oakland County officials admitted that they dumped an unprecedented 2.1 billion gallons of partially treated sewage into the Macomb County waterways during the massive Aug. 11 storm, environmental activists on Thursday called for a return to the policing of polluters that was in place several years ago.

These activists warned that drenching rainstorms are becoming more common, and sewage system overflows packed with fertilizers and other “nutrient-rich” discharges will increasingly lead to a Lake St. Clair shoreline plagued by algae, tainted water and seaweed-style aquatic plants dominating the water surface.

Agricultural Runoff is Polluting the Lake

Tom Henry, reporting for The Blade:

Jeff Reutter, the Ohio Sea Grant and Ohio State University Stone Laboratory director, frequently makes this point to groups hearing any one of the dozens of presentations he makes each year: More than two-thirds of today’s phosphorus in western Lake Erie comes from agricultural runoff. In the 1960s, more than two-thirds of it came from poor sewage treatment...

While people in Toledo may think of Lake Erie water quality as a sewage or factory issue, it is increasingly an agricultural land-use issue. The Maumee River watershed — the largest and the most important for western Lake Erie — is 73 percent agricultural land, Ms. Johnson said.

Mr. Reutter and other officials have been part of a state task force studying the phosphorus problem, which — to no one’s surprise — generally has been trending upward since 1995, when the first major bloom of toxic microcystis algae was detected in western Lake Erie since the 1970s.

One exception was during the drought of 2012. That, according to Mr. Reutter, only amplifies the strong correlation between agricultural runoff and western Lake Erie algae. In its latest report, the task force called for a 40 percent reduction in farm runoff.

Powerful the agricultural interests have become, the dark side I sense in them.

Questions About the Water Supply Plan

White Bear Lake is looking less like a lake all the time. The Met Council has released a report with a few solutions to this issue, all which involve relying more on surface water (rivers) and less on groundwater. The proposed solutions range in price from $155 million to over $600 million. The options are myriad, but all involve long pipes to existing or new water treatment plants that use water from the Mississippi River. Options for areas served vary, but the study area includes communities totaling 157,823 people in 2010 (208,580 projected in 2040).

However, the report seems insufficient to me. It lacks answers to lots of important questions that members of the Metropolitan Council (and residents of the region) should be asking. Here are a few I came up with as I was reading:

Brendon has 6 questions then asks one more:

Where is the conservation alternative? The cost and feasibility of reducing water use are not analyzed as part of the report. Building nothing and simply asking/incentivizing/requiring people to use less may be the cheapest option.

Great Lakes at a Crossroads

Despite their vastness, for thousands of years the inland seas above Niagara Falls were as isolated from the outside world as a Northwoods Wisconsin pond. That all changed in 1959. The U.S. and Canadian governments obliterated the lake’s natural barrier to invasive fish, plants, viruses and mollusks with the construction of the St. Lawrence Seaway, a system of channels, locks and dams that opened the door for ocean freighters to sail up the once-wild St. Lawrence River, around Niagara Falls and into the heart of the continent.

Small boats had access to the lakes since the 1800s thanks to relatively tiny man-made navigation channels stretching in from the East Coast and a canal at Chicago that artificially linked Lake Michigan to the Mississippi River basin.

But the consequences of opening a nautical freeway into the Great Lakes for globe-roaming freighters proved disastrous — at least 56 non-native organisms have since been discovered in the lakes, and the majority arrived as stowaways in freighter ballast tanks.

New species additions are a natural part of ecosystem life. Rejoice for those around you and admire the beauty of all organisms. Mourn a changed ecosystem do not. Miss them do not. Attachment leads to jealously.

A City in Denmark with Low Waste

“In 2006, 85 percent of our production was coming from, you can call it ‘black’ fossil fuels, the rest from green sources,” says Niels Christian Kjær, a top executive at DONG Energy and past president of the Kalundborg Symbiosis. “By 2040, we will switch that number: 85 percent will be green energy.”

With support from the central and municipal governments and the European Union, along with the companies, Kalundborg has attracted the attention of business people and investors, policy makers and students from all over the world who come to learn how they can create their own industrial symbiosis. In 2014 alone, it’s had visitors from Turkey, Thailand, Finland, Sweden, Kenya and Denmark, representing a farmers’ association, a development agency, an industrial think tank, an environmental institute, a waste management company, and several universities and high schools.

“What is excellent about Kalundborg is that the town hall has full focus in this,” says Kjær. “They want to be the leading town, number one in innovation. They want to have people come from all over the world to learn and say, ‘Wow.’”

Lake Erie is Polluted

Behind Toledo’s Water Crisis, a Long-Troubled Lake Erie

It took a serendipitous slug of toxins and the loss of drinking water for a half-million residents to bring home what scientists and government officials in this part of the county have been saying for years: Lake Erie is in trouble, and getting worse by the year.

Flooded by tides of phosphorus washed from fertilized farms, cattle feedlots and leaky septic systems, the most intensely developed of the Great Lakes is increasingly being choked each summer by thick mats of algae, much of it poisonous. What plagues Toledo and, experts say, potentially all 11 million lakeside residents, is increasingly a serious problem across the United States.

But while there is talk of action — and particularly in Ohio, real action — there also is widespread agreement that efforts to address the problem have fallen woefully short. And the troubles are not restricted to the Great Lakes. Poisonous algae are found in polluted inland lakes from Minnesota to Nebraska to California, and even in the glacial-era kettle ponds of Cape Cod in Massachusetts.

If you don't advance new pollution control efforts now — if you choose the quick and easy path — you will become an agent of darkness.

The Health Benefit of Trees

James Hamblin, writing for The Atlantic:

It is becoming increasingly clear that trees help people live longer, healthier, happier lives—to the tune of $6.8 billion in averted health costs annually in the U.S., according to research published this week. And we’re only beginning to understand the nature and magnitude of their tree-benevolence.

In the current journal Environmental Pollution, forester Dave Nowak and colleagues found that trees prevented 850 human deaths and 670,000 cases of acute respiratory symptoms in 2010 alone. That was related to 17 tonnes of air pollution removed by trees and forests, which physically intercept particulate matter and absorb gasses through their leaves.

In terms of impacts on human health, trees in urban areas are substantially more important than rural trees due to their proximity to people,” the researchers wrote. “The greatest monetary values are derived in areas with the greatest population density.”

Public Transit Rankings

Reuben Fischer-Baum, reporting for FiveThirtyEight:

New York is the only U.S. system to register on the international level. Most of New York’s trips were on the MTA subway (62 percent), followed by MTA buses (21 percent), NJ Transit buses (4 percent) and LIRR commuter trains (3 percent).

New York, Washington, Boston and Philadelphia — the urban centers of the “Northeast Corridor” — all fall into the top 10 in trips per resident. They also fall into the top 10 of urban population. Do certain regions tend to support better public transit, or is this just a product of city size and density?

Among all 290 cities, there’s a clear relationship between trips per resident and both total population (the r-squared is 0.41) and population density (r-squared = 0.21).

Rewilding Europe: reconstructing ecosystems by looking mostly forward

Elizabeth Kolbert, writing for The New Yorker:

The newest land in Europe could be used to create a Paleolithic landscape. The biologists set about stocking the Oostvaardersplassen with the sorts of animals that would have inhabited the region in prehistoric times—had it not at that point been underwater. In many cases, the animals had been exterminated, so they had to settle for the next best thing. For example, in place of the aurochs, a large and now extinct bovine, they brought in Heck cattle...

Perhaps it’s true that genuine wildernesses can only be destroyed, but new “wilderness,” what the Dutch call “new nature,” can be created. Every year, tens of thousands of acres of economically marginal farmland in Europe are taken out of production. Why not use this land to produce “new nature” to replace what’s been lost? The same basic idea could, of course, be applied outside of Europe—it’s been proposed, for example, that depopulated expanses of the American Midwest are also candidates for rewinding....

As more aurochs remains have been unearthed and more sophisticated research has been done on them, it’s become clear that the Heck brothers’ creation is a far cry from the original—Heck cattle are too small, their horns have the wrong shape, and the proportions of their bodies are off. All of which has led to a new, de-Nazified effort to back-breed the aurochs. This project is based in the Dutch city of Nijmegen, about fifty miles southeast of Amsterdam, and is entirely independent of the Oostvaardersplassen. Still, it reflects much the same can-do, “what is lost is not lost forever” approach to conservation.

We should increase the biodiversity of our domesticated places and conserve species diversity in our wild places. With regard to 'New Nature', we can admire the beauty of organisms regardless how they arrived in the dynamic, very changing world we also live in.

May you be with Nature. May Nature be with you.

 

Mass Extinction

Arthur Chapman

Several recent articles on EXTINCTION and Population Declines

John Timmer, writing for ArsTechnia:

At various times in its past, the Earth has succeeded in killing off most of its inhabitants. Although the impact that killed the non-avian dinosaurs and many other species gets most of the attention, the majority of the mass extinctions we’re aware of were driven by geological processes and the changes in climate that they triggered.

Unfortunately, based on the current rate at which animals are vanishing for good, we’re currently in the midst of another mass extinction, this one driven by a single species: humans. (And many of the extinctions occurred before we started getting serious about messing with the climate.) This week’s edition of Science contains a series of articles tracking the pace of the extinction and examining our initial efforts to contain it.
A comprehensive review of birds has identified hundreds of new species that have previously been lumped with known ones — and a quarter of the newly discovered birds are already being listed as threatened.

BirdLife International assessed the 361 newly recognized bird species on behalf of the International Union for the Conservation of Nature (IUCN). More than 25 percent of them were instantly placed on the IUCN Red List of Threatened Species. About 13 percent of all birds are already listed.
The decline of various animal populations and species loss are occurring at alarming rates on Earth, contributing to the world’s sixth mass extinction. While these deadly events may ultimately pave way for the emergence of new species, Stanford scientists have warned that if this “defaunation” that we are currently experiencing continues, it will likely have serious downstream impacts on human health. The study has been published in Science.

Biodiversity on Earth is extremely rich at present; it’s estimated to be the highest in the history of life on our planet. But scientists have been recording species abundance and population numbers for some time now and it is evident that we are experiencing a sharp downward trend. While the extinction of a species is normal and occurs at a natural “background” rate of around 1-5 per year, species loss is currently occurring at over 1,000 times the background rate.

Straits of Mackinac Oil Pipeline Failure Would be Disastrous

Keith Matheny, reporting for Detroit Free Press:

A rupture of 61-year-old, underwater oil pipelines running through the Straits of Mackinac would be “the worst possible place” for a spill on the Great Lakes, with catastrophic results, according to a University of Michigan researcher studying potential impacts of a spill.

David Schwab, a research scientist at the U-M Water Center, retired from the National Oceanic and Atmospheric Administration, where he studied Great Lakes water flows and dynamics for more than 30 years. He’s the author of a new study done in collaboration with the National Wildlife Federation looking at different scenarios for potential oil spills in the Straits from Canadian oil transport giant Enbridge’s Line 5.

“I can’t think — in my experience — of another place on the Great Lakes where an oil spill would have as wide an area of impact, in as short of time, as at the Straits of Mackinac,” Schwab said.

Line 5 is a set of two oil pipelines that runs from Superior, Wis., through the Upper Peninsula, underwater through the Straits and then down through the Lower Peninsula before connecting to a hub in Sarnia, Ontario. The lines transport about 23 million gallons of oil and other petroleum products, such as natural gas liquids, through the Straits daily.

Pain, suffering, death I feel would happen. Something terrible may happen. Terrible pain for this Black Swan.

Lake Erie Pollution

Layla Klamt, writing for Liberty Voice:

The National Oceanic and Atmospheric Administration (NOAA) released its forecast on Lake Erie’s summer algae bloom for 2014 this week, and at first glance, the numbers are alarming. NOAA and the International Joint Commission say that even though pollutants causing the algae bloom in Lake Erie are high, they are still on the decline from 2011.

Lake Erie is the smallest and shallowest of all five Great Lakes and also has the most river tributaries. Ohio, New York and Ontario, Canada share its borders, and Lake Erie is seen as a vital economic waterway, a source for drinking water and a valuable sewer treatment. The lake has been plagued by many ecological problems since the late 60s, including the toxic algae blooms, a number of invasive species and high levels of Mercury in its edible fish supply. Unfortunately because of all these problems, Lake Erie has come to be known as an environmental sore spot for the Environmental Protection Agency (EPA) and the NOAA. Efforts to clean up the lake’s shores and protect species have thus seemed like an uphill battle at times.

Powerful the pollution consequences become, the dark side I sense in them.

Let 'Em Eat Dirt

Quest to Save Groundwater

Zebra & Quagga Mussels are Change Agents in Lake Erie

Creatures living on, near, or below the bottom of the lake—is “fundamentally changed from its past,” according to a paper published online in the current journal of the Journal of Great Lakes Research. Lyubov Burlakova, who works with the Great Lakes Center at SUNY Buffalo State, is the first author. The coauthors are Alexander Y. Karatayev, director of the center; Christopher Pennuto, a research associate with the center and biology professor at Buffalo State; and Christine Mayer, associate professor of ecology at the University of Toledo.

“The story of Lake Erie shows how profoundly human activity can affect an ecosystem,” said Burlakova. She traces that activity as far back as the early 1800s, when people cut down forests and built sawmills and dams.
