Geo-medicine: Mapping our pollution exposures
My latest post on The Atlantic’s Cities website explores geo-medicine, a new field that uses GIS mapping to correlate environmental conditions to health risks like heart attacks and cancer. There’s even a free app that allows you to map the types of toxic exposures in everyplace you’ve ever lived and correlate them to the likelihood of developing cancer or dying of a heart attack.
Beyond charting the potential for your own personal doomsday, however, geo-medicine has many other applications: It can allow doctors to zoom in on a patient’s life to create a geographically enhanced medical history. Or it can zoom out to give public health officials, city planners and activists detail-rich insights on how to improve the well-being of entire communities.

Affordablity theme big in this year’s Solar Decathlon

In this year’s Solar Decathlon wrapped up earlier this month with 19 homes – more than half of which cost less than $300,000 to build. Affordability was one of the 10 categories on which the homes are judged this year in the biannual competition pitting universities from around the United States and a few foreign countries. The new cost/affordability bar, which replaced the lighting contest, inspired the student designers to drive down the cost considerably. According to the event’s sponsor, U.S. Department of Energy, this year’s houses were about 33 percent cheaper this year than those that competed two years ago. “Solar for less” was just one of the industry trends reflected in this year’s entries.

I Want this Bike Helmet!
So it might not go with all outfits, it’s a much bolder fashion statement than the standard offerings. And so much padding would be comforting if one’s skull were on a crash course with the pavement. If this one’s not for you, the TreeHugger site has an array of cyclist headgear on parade today. Several swerve decidedly into the fashion lanes. Others tilt toward practicality. I also like the collapsible helmet; unattractive but easily stowed. As a Capital Bikeshare members, I get tired of carrying my bulky plastic helmet around with me.
The Importance of Forests, Farmers + Product Safety
A few news stories of note this morning:
Seeing the forest’s role: “By 2025, 1.8 billion people will be living in regions with absolute water scarcity and two-thirds of the world’s population may experience water-stress conditions. Forests capture and store water and can play an important role in providing drinking water for millions of people in the world’s mega-cities.” The U.N. Food and Agriculture Organization calls on countries to recognize the links between healthy forests and drinking water supplies and do a better job protecting both.
Small farmers lead the way: In a just released short film series, TVE Asia Pacific profiles farmers in Cambodia, the Netherlands, Niger, and South Africa who are members of Prolinnov, a global network that promotes local level innovation by small farmers.

Forget about Halloween, the global extinction crisis is a true cause for fright
Some news stories seem to reoccur year after year despite their urgency. Today’s page 3 story in the Washington Post, “Global extinction crisis looms, study says,” is one of those. Here’s the first graf:
“A growing number of creatures could disappear from the Earth, with one-fifth of all vertebrates and as many as a third of all sharks and rays now facing the threat of extinction, according to a new survey assessing nearly 26,000 species around the world.”
Appalachia Rising in DC
People from Appalachia and around the country marched to the White House today to send a message to President Obama about mountaintop removal coal mining: Stop it immediately.
Mountaintop removal — or “mountaintop mining” — as coal companies such as Massey Energy prefer to call it — is a form of strip mining. The companies use explosives to blast off the tops of the mountains and heavy machinery to scoop up the valuable coal seams underneath. Tons of so called “waste rock” (the parts of the mountain of no use to coal companies) are trucked down into valleys, where they are dumped, a process called “valley fill.” Since mountaintop mining began a few decades ago, hundreds of mountains in Appalachia have been blown apart in this way and a couple of thousand of miles of streams and lakes have been buried under waste rubble, according to the EPA.

Earlier this week, this blog discussed the dilemma facing people everywhere who want both spot-free dishes and clean watersheds. Well, yesterday, the U.S. Environmental Protection Agency highlighted another part of the Chesapeake Bay‘s chemical runoff problem: It announced a crack down at the chicken and dairy farm run by the Petersheim brothers of Lancaster County, Pa.
EPA inspectors slapped the Petersheims with a $6,000 fine for allowing runoff from animal manure and milkhouse washwater packed with nitrogen and phosphorus to end up in a tributary of Chickies Creek, which feeds the Susquehanna River and eventually meets the bay.
According to the EPA press release, the brothers’ farm in Manheim, Pa., has about 80 dairy cows and produces eggs from about 36,000 hens. Is that a lot? After reading about the country’s massive factory farming operations that produce most of the eggs — and don’t forget the salmonella! — in the country, the Petersheim operation doesn’t sound terribly large and impactful. And, that just illustrates how diffuse and complicated a pollution problem the Chesapeake is facing. The EPA has outlined its plan to step up the long-running cleanup efforts, here. But the task is daunting and environmentalists have expressed lot of skepticism over the plans rolled out by the states bordering the bay. Meanwhile, the farmers are pushing back: A group of Virginia farmers are coming to Washington tomorrow to complaint about the EPA’s “heavy-handed” approach to the cleanup and lobby against stricter new legislation in Congress, according to this AP report.
Spotless Dishes v. Clean Water

White phosphrous molecule from Wikipedia Commons
A couple of news stories recently highlighted the dilemma posed by phosphorous, a chemical used to make explosives, fireworks, pesticides, toothpaste, detergents, among other things.
Like a verdant lawn? Thank phosphorous.
Want your glasses to sparkle when they emerge from the dishwasher? It’s the phosphates in the soap that makes sure no spots mare that perfect shine.
Once these compounds run off your lawn or down the drain, however, it’s not such a pretty picture: They end up local watersheds and quite literally suck all the air out of the river, lake or bay. OK, a more scientifically sanctioned way of saying it: the chemicals consume so much oxygen that it makes it hard for aquatic life to survive.
But, heck, at least the dishes look great, right? This New York Times story notes people are rebelling against detergent reformulated to ditch the phosphorous in favor of more environmentally friendly — but less spot-busting — ingredients.
Meanwhile, the Virginia Pilot reports on last Saturday’s face off between environmentalists and the administration of Virginia Governor Bob McDonnell over efforts to clean up the Chesapeake Bay, which has a hardcore phosphorous problem. The governor’s office is pushing a “nutrient trading” scheme that bears a strong resemblance to abandoned efforts in the U.S. Congress to set up a pollution cap-and-trade system. But Ann Jennings of the Chesapeake Bay Foundation isn’t buying the plan as a viable solution to the Bay’s long-running problems.
