A letter about the birds and bees

A Letter about the Birds and Bees

July 13, 2013
Dear Hort,

     I'm writing this aboard a train heading to Quebec. It's a gorgeous time of the year to ride the rails in Canada. Golden drifts of Black-eyed Susans brighten the side of the track, interrupted by occasional vivid orange flashes as we whip by a naturalized clump of daylilies. Pale tan giant cylinders of hay make mown farm fields look like a Magritte painting. In one area near the Kingston limestone flats I think I saw wild white phlox blooming, and every few kilometers brings a new ecozone with different flowers to enjoy. Zipping past a swamp, I saw a brilliant mound of what looked like Canada lilies growing on a bluff above the water...

   I'm on my way to Quebec City, whence a rental car and I will take a pleasant afternoon drive along the south shore of the St. Lawrence. We'll stop at Grand-Métis where my world-traveller cousin Paul [photo next email: Paul mugging it up with one of my giant heritage tomatoes] awaits us in a cabin looking out over the great river, which here partakes largely of the sea with two meter tides and fascinating tidepools just beside the deck. Tomorrow morning we will be off to celebrate Bastille Day at Les Jardins du Métis/Reford Gardens. I've brought my "Prince des Jardiniers" gardening hat from France along to shelter my balding pate from the hot July sun as we wander through the kilometers of gardens and landscapes of what is arguably Canada's finest grand garden. We have the promise of a personal tour from Alexander Reford, the gardens' owner, to look forward too, then dining at an auberge with a view of the sunset over the great river.

  But I'm visiting Grand-Métis for more than just garden tourism. I'll be giving a talk in the gardens about the birds and the bees, and if you know me you'll guess it won't be about sex, it will be about tobacco.

  Some of you may have caught my discussion with farmer and beekeeper Dave Schuit on Canada AM last week. [apologies for the ad - be patient, please!]. Dave and I were there to talk about the catastrophic losses he and other beekeepers are experiencing, as more and more of their honeybees die off over winter or during corn planting season. Dave and I agreed that although many diseases and pests are bothering the bees, the straw that breaks the camel's back is the widespread use of nicotine-based pesticides.


  Do you grow tobacco plants in your garden?   Last year I had three different species (I'm sending Nicotiana sylvestris, while the unusual blue leaves and golden tubular bells of Brazilian tree tobacco Nicotiana glauca gave foliage interest and flowers for daytime pollinators. But all tobacco species share one botanical innovation: the acutely toxic (to insects) nerve poison nicotine.

  Yes, that's right: nerve poison. The stuff is to most insects and water bugs as the horrible chemical nerve gases are to us. That's why chemists at Bayer, Monsanto, and other companies modified the structure of nicotine to make it last longer (up to years in some soils), reside permanently in the plant it is applied to, and be as toxic to bees as nerve gases are to us. These "neonicotinoid" pesticides now coat the

seeds of most commercial field crops, including corn, canola, soybeans, and even sometimes wheat. The manufacturers sell billions of dollars of product every year.

  If "neonics" (as most farmers and beekeepers call them) only killed corn rootworms, I wouldn't be talking about them in the gorgeous surroundings of Reford Gardens. But they go where they aren't meant to. Bees gather them up in pollen and in the sweet-tasting little droplets of sap young corn seedlings release at dawn. Birds eat them as they hunt for seeds that the sowing drill didn't get all the way underground. One droplet of seedling sap kills a bee, one coated kernel of corn can kill a blue jay, one grain of wheat can make a songbird sterile. Washed into streams and ponds, neonics kill the water bugs fish thrive on. And, just in case you don't care about the natural world at all, recent studies show small quantities cause abnormal development in the brains of newborn rats...an organism often used to test for possible teratogenic effects on human fetuses and infants. Mothers who smoke have children with ADHD more often than non-smokers - and nicotine is the reason. Do we want neonics in our food?

  This spring, for the first time in history, there weren't  enough honeybees to pollinate the California almond crop when the trees bloomed. The price of almonds is expected to double this winter. This summer, a landscaper was called in by a Target store in Oregon to get rid of pesky aphids in the trees around the parking lot which were shedding sticky honeydew on shoppers' cars. Problem is, a neonic pesticide was used ("knocks 'em right down"), the trees were linden trees in full bloom, and over the next day or so perhaps 50,000 dead bumblebees were found on the asphalt of the lot. Dave Schuit lost over 40% of his honey bees when neonic-treated corn was grown near his hives, and has had to sell his farm to recoup his losses (he had to choose between buying new bees or paying the mortgage, and opted for the bees).

  Some of us are old enough to remember Rachel Carson and her game-changing book Silent Spring. Dave and his fellow beekeepers in Ontario and Quebec are asking the federal government (which regulates pesticides) to follow the lead of the European Union in banning neonicotinoids before it's too late and we have silent springs, summers, and falls. We are well along this deadly path already. Numbers of birds like swallows and purple martins that depend on flying insects are down by 70-80% and still dropping. Please, will you consider writing to your M.P. and asking her or him to push the government to ban neonicotinoid pesticides to save the birds and the bees?

I close this letter with a silent prayer that future years will bring back the buzzing of the bees and the sounds of the songbirds.
Yours,
Clement Kent

A watershed victory for the Precautionary Principle - EU temporary ban on neonicotinoids

Breaking news - today, April 29 2013. The European Commission, by a vote of 15 in favor, 8 opposed, and 4 abstaining, has voted to approve a temporary ban on 3 neonicotinoid pesticides strongly suspected of harming pollinators, especially bees.

As reported in numerous sources (Guardian, BBC) the vote fell short of the required level to mandate a ban, leaving it to the Commission to decide whether to order a temporary one. Reports suggest the Commission will order a 2 year ban on the use of imidacloprid, clothianidin, and thiamethoxam for some uses, probably including seed treatment. During this period further studies will need to be conducted and reviewed, after which the decision will be revisited.

The "Precautionary Principle" is a relatively new generalization to the environment and public affairs of a very old idea, going back to the Hippocratic Oath's "never do harm" commitment. In medicine, this is often invoked as a reason to be very, very cautious in prescribing new, untried treatments, because the human body is so complex that only extensive tests and experience will make us reasonably certain that a treatment will not accidentally do more harm than good.

As extended to the environment, which is many times more complex than the human body and much less studied, the Precautionary Principle says that the burden of proof for those proposing to use or using the environment in new ways (e.g. new pesticides, new levels of pollution or new pollutants) should lie on the new users. That is, the default position of governments and regulatory agents should be "possibly guilty until proven innocent", just as a physician rightly insists of a new drug or surgical technique.

The World Charter for Nature (UN, 1982), the Montreal Protocol (1987-89), the Rio Declaration's Principle 15 (UN, 1992), and the Treaty of Lisbon (EU, 2007-09) have given the Precautionary Principle legal standing in many countries, particularly in Europe. And, a large number of recent publications, some of them discussed in this blog last year, and others in the last 6 months in the most prestigious scientific journals (1, 2, 3, 4), have greatly increased the evidence that this class of pesticide, as used now in agriculture, does do harm to bees of several types.

One of the earliest countries to take action on neonicotinoids was Italy, whose role I honor here with pictures of bees from the "Eternal City", Rome. France has also taken very positive steps, under pressure from the French public and beekeepers.

The European vote needs to be followed by still more research, as - surprise! - Syngenta, Bayer, and Monsanto are vigorously opposing attempts to declare neonics harmful to bees. No regulatory change has happened in Canada, where the government PMRA department involved has set itself a 2018 deadline to review evidence, but has been told by the Conservative government to cut their budget by 12%, fire scientists, and "streamline" pesticide registration. In the USA, beekeepers groups are suing the EPA to force action on neonics. In the midst of all this political turmoil, it will be very important to have clear, objective research done by farmers, beekeepers, and scientists without business ties to pesticide manufacturers nor to fringe advocacy groups.
