Deepwater horizon: an event horizon for the oil age?

In a speech given earlier this year, the Chief Economist for BP made his case that fears about peak oil were overblown.

"One factor is resources. They are limited, and a barrel can only be produced once. But ideas of peak oil supply are not true. Doomsayers have exaggerated the issue. The bell-shaped curve of production over time does not apply to the world's oil resources," he told the seminar in Alkhobar city. "Those who believe in peak oil tend to believe that technology and economics don't matter, and I think this is false.The application of technology, the innovation of new technology and economic forces especially mean that recoverable oil resources can increase. If there is a peak in oil, it will come from the demand side. There are always fears, but these remain overstated and exaggerated."
A barrel can only be produced once, this is true. And technology has allowed us to tap into oil reservoirs that were unthinkable a few decades ago. Yet as the catastrophic ongoing oil geyser in the Gulf of Mexico shows us, technology is not the savior the oil majors would have us believe. Advanced technology may allow us to drill for oil a mile under water, but it obviously does not offer any easy solutions when things go horribly awry as they have on the Deepwater Horizon rig, which has been spewing hundreds of thousands of barrels of oil into the Gulf of Mexico for over a month.

What’s behind the rise in ADHD?

Now a new study published in Pediatrics, the journal of the American Academy of Pediatrics, links pesticide use with the rise in ADHD disorders among children. The study's authors examined data on over 1,100 children, and determined that elevated levels of pesticide metabolites in the urine was associated with a diagnosis of ADHD. In fact, children with levels higher than the median of the most commonly detected metabolite (known as dimethyl thiophosphate), were twice as likely to be diagnosed as ADHD compared with children that had undetectable levels of the metabolite. The elevated risk factor remained even after controlling for confounding variables like gender, age, race/ethnicity, poverty/income ratio and others. The pesticides studied belong to a class of compounds known as organophosphates. Time explains:

[Study author Maryse] Bouchard's analysis is the first to home in on organophosphate pesticides as a potential contributor to ADHD in young children. But the author stresses that her study uncovers only an association, not a direct causal link between pesticide exposure and the developmental condition. There is evidence, however, that the mechanism of the link may be worth studying further: organophosphates are known to cause damage to the nerve connections in the brain — that's how they kill agricultural pests, after all. The chemical works by disrupting a specific neurotransmitter, acetylcholinesterase, a defect that has been implicated in children diagnosed with ADHD. In animal models, exposure to the pesticides has resulted in hyperactivity and cognitive deficits as well.

(Marginally) tougher food safety rules mean (marginally) safer food

"There is no more important mission at USDA than ensuring the safety of our food, and we are working every day as part of the President's Food Safety Working Group to lower the danger of foodborne illness. The new standards announced today mark an important step in our efforts to protect consumers by further reducing the incidence of Salmonella and opening a new front in the fight against Campylobacter," announced Secretary of Agriculture Tom Vilsack on Monday. Under these new proposed regulations, 7.5% of the chicken at a processing plant may test positive for salmonella. In 2009, average salmonella levels were at 7.1%, so I guess these giant food conglomerates won't have to stretch too hard to meet the proposed rule. I suppose it's better than the 20% salmonella contamination that's allowed under current regulations. But perhaps current regulations are not the best standard with which to judge the new rules, given that they don't regulate campylobacter at all. Campylobacter causes diarrhea, cramping, fever, and there are no federal standards governing how much of it can be in your food. Under the proposed regulations, companies may not have more than 10% of their carcasses "highly-contaminated" by campylobacter, and no more than 46% may be contaminated at a "low-level." I feel better, don't you?

Building lifeboats

I know that my past few posts have been bleak (see here and here), but now I must temper that sense of despair with some hope. Things are bad, and will probably get worse, but that's not to say that they will not get better. But here's the trick: we all have to stop relying upon someone else for solutions. Forgive me if I sound like a politician for just a moment: we must "be the change" we want to see in the world. I cannot tell you how to solve the peak oil problem, or the unfolding economic collapse, or climate change, or the corruption which has become endemic in our political system-- you have to figure it out for yourself. I'm not selling a prepackaged kit which contains all of the answers, and I would probably distrust anyone who was. But that's precisely why I still have hope. If we are going to make it through the challenges facing us, we must learn to pull together again as a community and actually attempt to create our own solutions. There can be no more delegation to those in Washington. We cannot afford to wait for decades as they attempt to muster the political will to combat the flood of money which has so damaged our electoral and political processes. We simply don't have time to fix the system that's been damaged beyond repair.

How’s your water quality?

The debate over tap water vs. bottled water will probably go on for quite some time. Many people believe that by purchasing bottled water, they are consuming better quality water than that which comes from the tap. Others argue that the environmental impact of bottled water is massive, and that bottled water is no safer than tap water. A report earlier this year from the Government Accounting Office claims that because public water supplies are regulated by the Safe Water Drinking Act and those regulations are enforced by the EPA, they are therefore safer than bottled water, which is regulated by the FDA-- and we all know what a wonderful job the FDA has been doing. But a new investigative report by the New York Times calls this conclusion into question.

In the last five years alone, chemical factories, manufacturing plants and other workplaces have violated water pollution laws more than half a million times. The violations range from failing to report emissions to dumping toxins at concentrations regulators say might contribute to cancer, birth defects and other illnesses. However, the vast majority of those polluters have escaped punishment. State officials have repeatedly ignored obvious illegal dumping, and the Environmental Protection Agency, which can prosecute polluters when states fail to act, has often declined to intervene.
