Wow, Conventional Milk makes Twins!

Byoliveridley

44m.jpgHoly tentacular twins, Batman! This is crazy news, the first study linking the incidence of twins with environmental factors. The culprit is growth hormone fed to cows to increase milk production. According to this Wikipedia article, a third of all dairy cattle use Monsanto’s rBGH (or rBST) brand Posilac®, so obviously, use is widespread.

FEED – July 2006 (from the Union of Concerned Scientists)

1. Engineered hormone in milk may be linked to twinning. A recent study found that women who consumed dairy products were five times more likely to give birth to twins than vegan women. The study suggested that the use of engineered bovine growth hormone/bovine somatotropin (BGH/BST) to boost milk production in dairy cows may be related to the higher level of twinning. BGH is known to increase twinning in dairy cows. In addition, the rate of human twinning is twice as high in the United States, where BGH is used, as in Britain, where BGH is banned. BGH affects twinning rate by increasing insulin-like growth factor (IGF), a protein produced in the milk of both animals and humans, that promotes ovulation and may help early-stage embryos survive. A separate study found that levels of IGF were 13 percent lower in vegan women than in women who consumed dairy products. Read a press release about the study, which was published in The Journal of Reproductive Medicine.

If true, no woman should ever drink “conventional” milk (non-organic, non rGBH free, etc). Twins are fun, I love my twin nieces very much, but they are much more difficult to carry and deliver, and there are more complications.

Scary, but I suspect this is the tip of the iceberg as far as environmental effects on childbirth are concerned.

  • Obama and Harper, saving a tree

    Canada hopes to achieve a North American climate-change deal with U.S. president-elect Barack Obama and will begin working on the file within weeks, Foreign Affairs Minister Lawrence Cannon said Wednesday.Meantime, officials told The Canadian Press the Harper government has been waiting for the departure of President George W. Bush to work with his successor on an integrated carbon market.While states and provinces have been cobbling together a patchwork of approaches, federal officials said they have been eyeing a continent-wide solution for some time.

    globeandmail.com: Canada to seek climate deal with Obama

    Interesting and potentially promising news. I have thought for a while that Canada would have no choice but to start some kind of emissions cap/trade or carbon tax, given the way the wind was blowing down south. Harper, for all his reliance on Alberta’s oil votes, realises that with or without his say, the country’s leading trading partner is going to impose a carbon tax (a cap and trade is a price on carbon, or a tax, semantics aside) on Canadian-US trade.

    It is also interesting that this statement came out right after Obama’s election, and the foreign minister went out of his way to say that they were waiting for Bush to get out of the way. Nice cozying up, Harper, making up for all your stupid previous statements about Obama. But do not worry, this new emperor is more gracious than the previous one!

    We are going to be living in interesting times, good ones, finally.

    California Ban on Diacetyl?

    Byoliveridley

    Flavoring-Factory Illnesses Raise Inquiries – New York Times

    For a good background on flavoring-factory lung disease (formerly known as popcorn worker’s lung), check out the Pump Handle’s many posts, especially this recent one. Short primer, diacetyl is the chemical that gives popcorn its so called buttery taste (and smell, it’s fake!!). Well, there’s pretty good evidence that diacetyl causes bronchiolitis obliterans. Some symptoms…

    Bronchiolitis obliterans renders its victims unable to exert even a little energy without becoming winded or faint.

    “The airways to the lung have been eaten up,” said Barbara Materna, the chief of the occupational health branch in the California Department of Health Services. “They can’t work anymore, and they can’t walk a short distance without severe shortness of breath.”

    OSHA has been unwilling to seriously regulate diacetyl, so California, as it is wont to do, is considering banning this killer chemical.

    But in California, which has 28 flavoring plants known to use diacetyl, some legislators and government officials seem unwilling to wait. A bill to ban diacetyl in the workplace by 2010 has passed two committees in the State Assembly and could be taken up by the full body this summer. It is the first proposal of its kind in the nation. Assemblywoman Sally Lieber, the author of the bill, said she introduced it because of what she said was the slow response by the flavoring industry, which is largely self-regulating on occupational safety. “What we’ve heard is that the flavoring industry has known for years that this is potentially a problem, and they haven’t taken action,” said Ms. Lieber, a Democrat.

    I am all for California’s regulation. But as written, this law will only protect workers in California. They should also consider going one step further by restricting the use of diacetyl in food sold in California. Only then can the giant market that is California exert its influence on the diacetyl manufacturers and users.

  • More Focus on China – Pesticides and Food Safety

    Byoliveridley

    I begin to wonder how much of this was not known previously, and is coming out now, pushed by US domestic food interests who can suddenly become a little more competitive.

    Reuters AlertNet – Pesticides next frontier in China food safety

    China’s farmers overuse pesticides, skip protective clothing and have at their fingertips an array of banned and counterfeit products, raising another area of concern in the country’s fragile food chain. Spraying chemicals on crops improperly or using products that may be fake or banned risks the health of China’s hundreds of millions of farmers and could lead to unsafe levels of residues in fruits and vegetables, experts say. “The government has to stop banned or illegal pesticides being available in the market,” said Angus Lam, a Greenpeace Campaign Manager for Food and Agriculture based in the southern city of Guangzhou. China banned five high toxicity pesticides as of Jan. 1, but Lam said old stock was still in the market, in the hands of traders, retailers and farmers themselves. The government pledged last week to step up inspections in its food industry, saying checks on fertilisers and pesticides would be one of the priority areas.

    China is not alone in this problem. Pesticides get overused in the US as well. But it’s as if all of a sudden, the mainstream press is waking up to the reality that is China. It is a developing country with high levels of growth in manufacturing, and a burgeoning middle class. But government regulation mechanisms have a long way to go to catch up.

    The US surely knows this, and needed to have a more stringent testing regime with food imports from China. But the FDA was not given the mandate or the money. It is very easy to blame the FDA here. The fact of the matter is that any agency is only as good as the money and mandate it’s given. The political will to take a good look at where your food comes from, and how to ensure its safety needs to come first.

    Who is Majora Carter?

    Majora Carter is a visionary voice in city planning who views urban renewal through an environmental lens. The South Bronx native draws a direct connection between ecological, economic and social degradation. Hence her motto: “Green the ghetto!”

    With her inspired ideas and fierce persistence, Carter managed to bring the South Bronx its first open-waterfront park in 60 years, Hunts Point Riverside Park. Then she scored $1.25 million in federal funds for a greenway along the South Bronx waterfront, bringing the neighborhood open space, pedestrian and bike paths, and space for mixed-use economic development.

    h/t the grist for bringing this incredibly powerful video to my attention.

    The EJNet site is a great place to start if you want more information about Environmental Justice.

  • Rapture watch – Extremely weird weather edition

    Byoliveridley

    Via the grist blog. Apparently, there has never been a cyclone in recent memory in this area.

    What if Hurricane Katrina had hit the Persian Gulf coast? | Gristmill: The environmental news blog | Grist

    Well, we might find out, according to an exclusive from The Oil Drum and Chuck Watson of KAC/UCF, also using a weather blog, where Margie Kieper writes:

    An unusual event is happening over the next 48 hours, as the first tropical cyclone with hurricane-force winds, and major hurricane-force winds at that, is approaching the Gulf of Oman, to strike the eastern coast of Oman, curve northward, and make landfall on the coast of Iran. In the tropical cyclone best tracks and the modern era of weather satellites, there is no record of such an occurrence.
    As the Oil Drum writer comments:

    Why might [Cyclone] Gonu matter? Well, that answer begins with the fact that the world production of petroleum plateauing around 85 mbbl/day, any slight blip in supply or exporting could be quite noticeable on the world markets. A sizable portion of the world’s petroleum exports go through the Gulf of Oman.
    Hmm … could global warming have something to do with it? Will global warming lead to higher oil prices and scarcer gasoline?

  • BC's Carbon Tax Chugs Along

    Byoliveridley

    Premier Gordon Campbell says he won’t bend to northern concerns about his carbon tax, but avoided saying so yesterday in a keynote speech to a meeting of northern B.C. communities, who have challenged him to revise the tax.

    reportonbusiness.com: ‘We are not changing the carbon tax. No,’ B.C. Premier says

    One of the loudest arguments being made against BC’s pioneering carbon tax proposal is that communities in Northern BC, much colder and much more rural than Vancouver and Victoria, will pay an “unfair” share because they need more carbon to heat their homes and drive their cars/trucks longer distances. The weather and lack of density ensure that they will pay higher carbon taxes, so it is unfair.

    Well, sorry! Victoria and Vancouver have been paying a fair weather premium for years in higher home prices, higher property taxes, higher prices on lots of things because that’s what city dwellers do without complaint. You can buy an average single family home in Prince George for $125,000, which may get you a garage in Vancouver!

    Cities are more efficient, and use far less energy per capita because of the density and transit options. Pricing carbon starts bringing some of these efficiencies to the forefront and that is a good thing.

    BC’s carbon tax is not perfect by any means. But, it is a start and it gets people thinking about consumption. Believe me, carbon’s on a lot of people’s minds here in BC. There’s tons of talk about carbon sinks and sources in the media. The carbon tax has definitely contributed to an increase in conversation about choices and their consequences. The funny thing is that the proposed carbon tax on gasoline has been dwarfed by actual market driven increases in gasoline prices. The important difference is that a carbon tax is a revenue stream that goes to funding carbon free energy sources. So, a tax, however small, is still preferable to the profits going to companies that deal in carbon.

    Hurray for BC and its carbon tax attempts. It is a decent start and one that I hope will be adopted by the rest of Canada and that wee country south of the border!

  1. Cool, one more thing that I can safely do that a woman. Or wait….does it make a difference if a man drinks the milk and then … you know… does the happy? Dang!

    I’m lactose intolerant anyway, like over 90% of South Indians. I’m glad to just not throw up. I like my coffee without cream, thank you.

  2. Nope, it\’s all on the woman\’s side! Of course, this is not why milk plays such a prominent role in Tamil movies (\”first night\”, anyone!), most Indian milk is hormone free, hormones being a little too expensive.
