Canada's Asbestos Time Bomb

Horrible story coming out of California.
Pot farms ravaging park land / Big raid in Marin County only hints at the extent of erosive techniques by growers

The discovery of 22,740 marijuana plants growing in and around Point Reyes National Seashore last week wasn’t only the biggest pot seizure ever made in Marin County. It was an environmental mess that will take several months and tens of thousands of dollars to clean up. The crops seized on the steep hillsides overlooking Highway 1 were planted by sophisticated growers who cleared vegetation, terraced land, drew water from streams through miles of irrigation hoses and doused acres of land with hundreds of pounds of fertilizer and pesticides.

To avoid the obvious “Pot Legalization” questions and flip it, consider a world where cigarettes have been banned/regulated to the extent that black market growing became viable, would this happen with tobacco? Obviously, the nature of the growing (Tobacco – plains, easy plant to spot, Cannabis – Hill sides, easy to hide), make it an operation question in addition to an economics question. But as the above report states, the operation was obviously not hard to spot, nor was it low impact.

Something to consider as actions widely prevalent in populations are made illegal, how well does prohibition ever work?

Benzene Levels in Soft Drinks Above Limit – Yahoo! News

WASHINGTON – Cancer-causing benzene has been found in soft drinks at levels above the limit considered safe for drinking water, the Food and Drug Administration acknowledged Wednesday.
Even so, the FDA still believes there are no safety concerns about benzene in soft drinks, or sodas, said Laura Tarantino, the agency’s director of food additive safety.”We haven’t changed our view that right now, there is not a safety concern, not a public health concern,” she said. “But what we need to do is understand how benzene forms and to ensure the industry is doing everything to avoid those circumstances.”

The admission contradicted statements last week, when officials said FDA found insignificant levels of benzene.

In fact, a different study found benzene at four times the tap water limit, on average, in 19 of 24 samples of diet soda.

The formation of benzene in soft drinks is from the reaction of ascorbic acid (aka Vitamin C) and benzoate salts, notably sodium benzoate which is used as a preservative. As the FDA letter states:

We learned that elevated temperature and light can stimulate benzene formation in the presence of benzoate salts and vitamin C, while sugar and EDTA salts inhibit benzene formation.

Is this a pressing concern? First of all, exposure modeling done by the EPA indicates that 93% of all benzene exposure is through inhalation (cigarette smoke, indoor offgassing, that wonderful refueling smell!), with 7% exposure through oral ingestion. So, potentially elevated levels in this 7% fraction are not likely to greatly increase exposure. In addition, the 5 parts per billion level for drinking water is set based on an assumed daily consumption of 2 liters per day (Source – USEPA), a safety factor up from the actual estimated 0.9-1.2 L per day measured consumption. Assuming the average amount of benzene in soda (mainly diet, mind you) is 4 times that of drinking water, a 500 ml dose of diet soda per day is required to equal the dose from drinking water, which mind you, only counts for 7% of the total bezene exposure. So in a sense, a person drinking 2 servings of diet soda per day would exceed the exposure from drinking water at the federally regulated level, and knock the socks off the California standard of 0.13 ppb in water. This will increase his/her known oral exposure. The total exposure to benzene of that individual, however, would not go up significantly because the overwhelming majority of the exposure still occurs through the nose, not through the mouth.

The issue here, and benzene is just the symptom, is that consumers know much more about their drinking water than they do about their manufactured food products, and that is not good for the consumer or for the industry because in the absence of knowledge and full disclosure, both parties are vulnerable. Which is why attempts to limit consumer knowledge hurt everyone.

Conclusion Please don’t stop drinking soda because of this, I am sure you can find plenty of other reasons to limit your soda consumption… Drink lots of filtered tap water, it’s the best!! And, I can assure you that most tap water is tested thoroughly, it’s zero calories and cheap!

Canada’s greenhouse emissions soaring: UN report

The figures are based on the 2009 national inventory report that Environment Canada quietly filed last week with the United Nations to meet its international reporting obligations. The full 673-page inventory is available on the UN’s website and shows Canada has the dubious distinction of having its emissions climb more since 1990 than any other G8 nation.

Canada ranks “first among the G8 nations” for increasing emissions, the report notes, even though Canada had committed to cut them. It notes that while Canada’s emissions have soared, Germany chopped its emissions by 18 per cent between 1990 and 2006, and the United Kingdom slashed its by 15 per cent.

Hey, we’re first in the G8 in something! The increase was driven primarily by increasing Tar Sands emissions thanks to the oil boom. Cars and coal also contributed.
