Organic food reduces organophosphate exposure in children

By now, I think most people understand that organic food is supposed to be healthier for you. But I think there are still some people who feel that the health benefits are a just a bunch of marketing hype.

Well, this new study suggests that it ain't just hype -- organic produce really does reduce kids' exposure to some potentially risky pesticides. From the Seattle P-I:

The peer-reviewed study found that the urine and saliva of children eating a variety of conventional foods from area groceries contained biological markers of organophosphates, the family of pesticides spawned by the creation of nerve gas agents in World War II.

When the same children ate organic fruits, vegetables and juices, signs of pesticides were not found.

In case you’d forgotten, industrial meat is a friggin’ nightmare

It’s a little weird that no one on Gristmill has yet pointed to Mark Bittman’s stellar NYT piece on the environmental ravages of industrial meat. Philpott, where you at? Anyway, […]

Will peak oil force the localization of agriculture?

Stuart Staniford says no. Sharon Astyk says yes. Jeff Vail also says yes.

Let cows eat vaccines along with distillers grains

In December, a study came out suggesting a link between distillers grains — a waste product of the corn-ethanol process — and a spike in cases of beef tainted with […]

Orange County opens recycled-water plant

A sewage reclamation plant officially opened today in Orange County, Calif., and will, sure enough, reclaim treated effluent and turn it into drinking water. Recognizing that its growing population — […]

The most critical assumption on cellulosic biofuels: yields

My most critical assumption with cellulosic biofuels is on land efficiency: tons of biomass per acre, and hence gallons of fuel produced per acre, and more accurately, miles driven per acre. I believe biomass yields per acre will multiply by two to four times from today's norms.

The lack of genetic optimization and research on cultural practices, harvesting, storage, and transport with would-be energy crops -- miscanthus, sorghum, switchgrass, and others -- means that there is significant potential for improvement. The application of advanced breeding methods like genetic engineering and marker-assisted breeding, limiting water usage through drought resistant crops, and large-scale application of biotechnology (i.e., optimizing the process by which plants conduct photosynthesis, or reducing stress-based yield losses) will also contribute to increased yields with fewer inputs.

More importantly, different energy crops are likely to be optimal for different climates -- jatropha makes sense on degraded Indian land, but not in the American Midwest. Rather than a single dominant energy crop, we are likely to see a variety of feedstocks that allow specialization to local conditions, mixes, and needs, while mitigating the risks.
