England’s plan for GM trees, and the possible ramifications

Another one of our weekly guest posts from Jonathan Javitt:

A group of researchers from the University of Southampton are hoping to establish a settlement of genetically modified poplar trees on land owned by the Forestry Commission as part of a research project into biofuels. Sounds good on its face – modified trees that may help us solve some of our oil dependency problems. But it’s not that easy. The truth is, these trees would present a whole other set of problems.

Clare Oxborrow, A campaigner for the eco-friendly organization, Friends of the Earth, explains the potential problems: “Our concerns with GM trees are even more serious than crops because trees are very long-lived. They are inherently geared up for spreading seeds and pollen because of the way they reproduce. There’s a huge potential for cross-pollination. It could have a really negative impact and cause widespread ecological damage.”

The proposed plantation would be the first attempt to cultivate genetically modified trees in Britain since 1999, when activists destroyed 115 plants. Those particular trees were super-trees – they had been modified to grow at four times the rate of a normal tree. That means they used more oxygen, more resources(what resources?), and could reproduce and pollinate faster. Campaigners have said that they will fight the new, similar plan amid warnings that allowing the move to go ahead would be “an unknown and worrying risk” for Britain’s ecosystems.

Meanwhile, eco-organizations are cautioning that the government should think carefully before giving the project the go-ahead. As I talk about in Capitol Reflections - and as with any scheme involving genetic modification - there is no doubt much more than meets the eye, and many serious issues to consider, on both sides of the argument. True, my book is fiction but many of the debates and issues raised in it are things that are happening on the forefront of the genetically modified foods movement. The American people as a whole need to be made more aware of this movement as we address issues like the one mentioned above.

Treacherous Kisses?

Our weekly guest post from Jonathan Javitt, author of Capitol Reflections:

Genetically modified (GM) beet sugar is generally used to make Hershey's Kisses – but that will no longer be the case in Brazil. The company recently announced it won't use GM beet sugar in its Brazilian-made products, but Hershey has not made any such promises for its US products.

In light of this, a number of consumer watch-dog groups in the US are urging people to take action; several years ago, Hershey told U.S. consumers it would not use genetically engineered sugar. But now genetically modified sugar beets are being planted commercially in the US and Hershey is utilizing sugar made from these plants for their hugely popular “Kisses” candy.

Additionally, the nation's largest sugar manufacturer, Crystal Sugar (from whom Hershey buys its sugar), said in the past that they would not be using GM sugar beets and indicated that herbicide-resistant varieties developed using biotechnology would not “be sold, given away, distributed, or planted.” But it doesn't look like that promise has been kept.

The New York Times reported last year in an article, “Round Two for Biotech Beets”that the sugar manufacturer abandoned its promise not to use genetically-modified sugar because public resistance to GM foods seems to have faded. Crystal Sugar and others now support the cultivation of GM beets because it will increase yields. According this article, beet sugar is unlike many GM foods in that the sugar molecule in GM beets is identical to the sugar molecule made by non-GM beets. Sugar, as a pure, crystalline substance contains no genetically modified strands of DNA or proteins.

GM beets are produced by Monsanto, which is a concern to many consumer groups – and agriculture activists - because of perceived dangers of Monsanto’s pesticide resistant technology and the aggressive marketing to farmers who don't use their products. The GM beets are called Roundup Ready Beets because their DNA has been altered to survive applications of Roundup weed-killer.

Consumer groups are concerned about the introduction of GM foods for human consumption in the US because there are no clear requirements for pre-market safety testing. The nation’s food safety laws were written before GM foods were conceived and although those laws focus on proving the safety of food additives and adulterated foods, genetic modification is considered neither an additive nor an adulterant.

While these issues are debated, still others are worried about Monsanto's central role in our food supply. As I mention in my book, altering the food supply could potentially play a big role – and cause big problems – in our society. In the “real world,” this is easy to see - increasing use of GM seed and food gives Monsanto – a GMO giant - a great deal of control over the production of food, and only a handful of corporations like Monsanto are involved in agricultural biotechnology.
