GE, GM, …. no way. And here’s why.

Despite what I said in my last post here about getting back to reporting on actions in the Lockyer Valley, by us or others, that contribute to sustainability and letting go of the “big issue” stuff, some things are just so locally relevant (well, of course it all is, but you know what I mean) that they can’t be ignored.

In a valley where a multitude of crops are grown on an industrial scale, we need to be continually reminded of the very real dangers associated with genetically modified crops.  To that end, I feel compelled to re-blog the following from Jerry Coleby-Williams’ always thoughtful and informative blog.  It’s a letter that he wrote to the Courier-Mail back in 2005, but its relevance is timeless – and thanks to Jerry for including references for key facts.  There are a lot of bloggers, particularly in permaculture, who need to learn that backing up their statements with credible sources will motivate people to adopt and spread their message.

Here’s Jerry’s letter to the C-M:

“Biodispersal – Another word for the dictionary

Unlike Dr Marohasy (‘Let’s be smart on genetic crops, Courier Mail, 22.11.05), I’ve learned to be cautious about what governments, scientists and businesses say about new technologies.

I well remember British scientists announcing that nuclear power was going to be so cheap, safe and effective that electricity would be supplied free.

I’ve heard much pontificating about the edenic opportunities that genetic engineering (GE) offer Australia. GE will allow us to tailor diseases to exterminate vermin, reduce chemical use, improve crop yields, etc.

Smart Techniques. Pinpoint Accuracy, 100% Satisfaction Guaranteed. Simple, just trust in our technology. We Can See The Future.

So how accurate a technology is GE? How much thought has gone into the consequences of its use?

The history of our previous field experimentation in Australia give us clues as to how these things work. Either the proponents of GE are aware of the dangers and are hiding them, as did the Maralinga nuclear testers, or they are as blissfully ignorant as the introducers of the cane toad.

In the 1950’s and ‘60’s atomic weapons research was the equivalent of GE: cutting edge technology. It was hard to argue for caution without being labelled a commie, a nut, or both.

The Maralinga Tjarutja, then not even Australian citizens, were forced from their traditional land to make way for British nuclear tests: safe, controlled field trials of new technology.

Plutonium 239 loses half of its radioactive strength every 24,000 years. The testers knew that it would be safe for the Maralinga Tjarutja Aboriginal people to reoccupy their homelands after a mere quarter of a million years.

There is an almost rustic charm about nuclear pollution and feral vermin, like the cane toad. You know what they are, you know what they do and you know that their behaviour is governed by natural laws.

This is NOT true of GE. A few years ago a German biotechnology company genetically engineered a soil bacterium, Klebsiella planticulata, to decompose organic waste and at the same time generate ethanol for use as fuel. Before field trials began this new GE life form was tested in real, living soil in a laboratory.

This was very unusual: normally such tests would be done in sterilised soil. Every single plant that was grown in soil innoculated with the GE Klebsiella died. The new life form affected all the mycorrhizal fungi present in the soil.

These microscopic fungi interact intimately with plant roots assisting plant nutrition and health. Without them soil is practically useless to plants. Critically, had normal tests been completed in sterilised soil no such results would have been seen. Field trials in the natural environment would have followed. A GE life form, capable of making soil inhospitable to plant life, would have been released into the world.

In October 2002, a large dust storm, apparently visible from space, and carrying millions of tonnes of soil, stretched from northern Queensland to southern NSW and spread soil east as far as New Zealand. Dust storms carry many things apart from soil: micro-organisms, pollen, seed, eggs, spores and, perhaps, a pinch of Plutonium 239. So had this Klebsiella been trialled in Australia it might have become our Christmas gift to New Zealand.

If two supposedly geographically isolated bioregions can share genetic material so easily, it seems that a ‘controlled field trial’ is more soft terminology than hard science. In 1999 the first GE Superweeds – wild turnips (Brassica rapa) – were identified in Britain, following the ‘controlled field trials’ of a GE crop of canola (Brassica napus). These two plants share a variety of insect pollinators which spread GE pollen from crop to wild plants which then inherited a gene for herbicide resistance which they in turn passed to the next generation.

Until the advent of GE, the scientific definition of a species was a life form with a unique genetic makeup that had developed to survive the environment and ecosystem within which it had evolved over time. Natural laws of inheritance ensured that a species is genetically distinct and tends to avoid hybridising with other species. The more distantly related species are the more unlikely it is that hybridisation will occur between them: so far barramundi have never crossbred with eucalypts.

Genes defining a species were contained within its population to be inherited – vertically – down the generations, from parents to offspring. The natural world is now a laboratory where a new phenomenon – horizontal gene transfer between species, between genera, phyla and kingdoms – seems both easy and expected.

Small wonder apologists like Marohasy are spinning like mad: they need to pollute Australia with GM in order to end all precautionary State GM bans. Currently GM technology is about profit and avoiding having to pay for cleaning up your own pollution.

Every new technology has a downside that is discovered AFTER its application: atomic energy generates nuclear waste; pesticides give us bioaccumulation of poisons. With pesticides we invented the word ‘bioaccumulation’ to describe the phenomenon of pesticide residues and pesticide breakdown products accumulating towards the top of the food chain.

So here’s a new term for the movement of pollution from GE – ‘biodispersal’ – for the new phenomenon of modified genes weaving their way unpredictably across the laws of natural inheritance and widely dispersing themselves throughout the web of life on Earth.

I’m all for improving our knowledge on genetics, that is genuine, ethical, hard science. But GM technology is inherently unsafe and unnecessary and we urgently need laws to compel GM business to pay for cleaning up their pollution”.
