Monsanto’s Genetically Modified Wheat Scare

A discovery of an unapproved GM wheat strain in the US triggers a backlash on global wheat markets.

The discovery
Last month an Oregon farmer sprayed one of his fields with Roundup weed killer, only to find that several wheat plants survived the cull. When the US Department of Agriculture investigated, it found out why: the plants were an unapproved genetically modified strain made by the biotech giant Monsanto. So-called “Roundup Ready” modifications allow farmers to apply much higher levels of pesticides without harming crops, and are common in soy and corn—but those crops are mostly used for animal feed. No GM wheat is currently approved for sale or production in the US, or anywhere else in the world. 

Monsanto was authorized to test their GM wheat from 1998 to 2005 in 16 US states. It did, but decided to scrap the variety because there wasn’t much of a market. The crop never received final approval. 

The problem 

The wheat is not probably not harmful to humans—although since testing was never completed, we can’t be sure.  Nevertheless, most of Asia (not to mention Europe and a certain portion of the United States) is firmly opposed to GM crops made for human consumption. Asia consumers around 40 million tonnes of wheat a year—about a third of the global total—and much of it comes from the US, the world’s biggest exporter. 

The reality of GM testing a product in open fields is that it’s quite easy for cross-contamination. It’s like the dinosaurs in “Jurassic Park”—no matter how well-designed the safeguards, life always finds a way to jump the fence. Doug Gurian-Sherman, a scientist with the Union of Concerned Scientists in Washington, told Bloomberg Businessweek he “wouldn’t be at all surprised if there are a number of experimental genes that have contaminated and are happily being passed along at low levels in the food supplies of various crops already, but nobody’s testing. It’s really a ‘don’t look, don’t tell’ situation. We just really don’t know.”
The fallout
Japan has already cancelled its imports of some types of US wheat including white grains and animal feed. China, South Korea and the Philippines have all said that they are monitoring the ongoing US investigation, and the European Union said it was stepping up testing. China, which is expected to need much more imported wheat in the coming years, is expected to import 3.5 million tonnes in the year to June 2014. The Philippines imports around 4 million tonnes each year, according to Reuters

But the damage to US exports is only likely to go so far. As the biggest exporter of wheat (around a fifth of global supplies), the US is indispensable for wheat importers, particularly in Asia where the climate is not particularly well-suited to the crop.

The hullaballoo over GM wheat has prompted US wheat futures to close at a three week high

My impression is that this could just be a short term scare. For today's financial markets, which have been bereft of price discovery from sustained interventions, sensational developments like this tends to magnify the emotions of greed or fear.

The World First Genetically Modified Babies

Given that the technology has been existing then having the first genetically modified humans seems of no surprise to me.

From Daily Mail.com

The world's first genetically modified humans have been created, it was revealed last night.

The disclosure that 30 healthy babies were born after a series of experiments in the United States provoked another furious debate about ethics.

So far, two of the babies have been tested and have been found to contain genes from three 'parents'.

Fifteen of the children were born in the past three years as a result of one experimental programme at the Institute for Reproductive Medicine and Science of St Barnabas in New Jersey.

The babies were born to women who had problems conceiving. Extra genes from a female donor were inserted into their eggs before they were fertilised in an attempt to enable them to conceive.

Genetic fingerprint tests on two one-year- old children confirm that they have inherited DNA from three adults --two women and one man.

The fact that the children have inherited the extra genes and incorporated them into their 'germline' means that they will, in turn, be able to pass them on to their own offspring.

Altering the human germline - in effect tinkering with the very make-up of our species - is a technique shunned by the vast majority of the world's scientists.

Geneticists fear that one day this method could be used to create new races of humans with extra, desired characteristics such as strength or high intelligence.

One way or another people’s curiosity will lead to more experimentation, which is why we should expect human cloning to be next, in spite political opposition.

This reminds me of two “cloning is bad'” movies: Scarlett Johansson’s The Island and Arnold Arnold Schwarzenegger‘s the 6th Day

Expect the rapid changes in technology to challenge people’s ingrained beliefs and lifestyles.
