Vilsack’s USDA shakes things up
I know some are still reeling from the recent Obama administration announcement on biofuels and its implication that it remains a bit too much in thrall to the concerns of Big Ag. And Tom Vilsack’s continued pimping for Monsanto and other biotech companies seems both unsustainable and uninformed. But a slew of positive decisions have […]

For some eco-pioneers, solving the sludge problem means getting their hands dirty
Part 3 of Grist’s special series on poop. Laura Allen, a 33-year-old teacher from Oakland, California, has a famous toilet. To be honest, it’s actually a box, covered in decorative ceramic tiles, sitting on the cement floor of her bathroom like a throne. No pipes lead to or from it; instead, a bucket full of […]

Sludge, farmer’s friend or toxic slime?
Should what we put down our sewers ultimately wind up back on our plates?Marc Samsom via Flickr Urine, feces, menstrual blood, hair, fingernails, vomit, dead skin cells. Industrial chemicals, pharmaceuticals, soaps, shampoos, solvents, pesticides, household cleansers, hospital waste. Sewage sludge, the viscous brown gunk left over when wastewater is treated, is more than just poop: […]

Humans have never left a small footprint, we have always tried to shape the environment to suit our needs. Initially farming had one purpose, food; farming provided a more stable […]

Regulating biosolids
Biosolids are regulated under what’s known colloquially (to those who speak colloquially about sewage) as the 503 Sludge Rule, which came into effect in 1993. Technically titled “40 CFR 503 — Standards for the Use and Disposal of Sewage Sludge,” it’s complicated enough that EPA came out with a “Plain English” guide to help make […]

Now is not the time for timidity
I agree with the calls for some amount of caution in the search for a smoking gun in the swine flu pandemic. There’s always the danger of over-reaching and turning your target into an object of sympathy. But really, the science IS behind us on this one. The head virologist of the CDC has indeed […]

Jumping to conclusions in health matters may have adverse side effects
The past week, the Netiverse has erupted with stories linking the Granjas Carroll confined animal feeding operations (CAFOs) near La Gloria, Vera Cruz, Mexico, with the outbreak of a strain of H1N1 influenza, commonly called “swine flu,” that has triggered concerns about possible flu pandemic reminiscent of the one that claimed tens of millions of […]

CDC: swine flu strain has genetic roots in U.S.A.
(Another hat tip to the increasingly essential Tom Laskawy.) In an interview with Science Magazine, CDC chief virologist Ruben Donis essentially confirmed the reading of the current swine flu strain made by New Scientist: that it evolved from a strain that cropped up in U.S. hog farms in 1998. Both New Scientist and Donis emphasize […]

‘New Scientist’: Swine flu stems from virus that evolved in U.S.
In a pair of articles in New Scientist, Debora MacKenzie links the swine flu virus now spreading across the globe to large-scale pork-raising operations in the United States. In the first article, titled “Swine flu: the predictable pandemic?,” MacKenzie writes that the “virus has been a serious pandemic threat for years, New Scientist can reveal […]
