GM, Blowing in the Wind

The Sciencemag website has an article that will lead me into today’s post, about an organic farmer in Australia who has taken his neighbour to court over GM contamination. The organic farm has traces of GM materials that have apparently blown in from the neighbouring farm, leaving authorities no choice than to take away the farm’s organic certification.

This has of course led to a loss of income, and so the owner is suing for $85,000 to recoup his losses.

Now although there are standards about leaving space between GM and non GM plantation, it has become increasingly clear that contamination is somewhat inevitable, and this is reflected in regulations.

In the US a farm can have organic status even in 5% of its produce is found to be GM (presumably from air borne contamination). In the EU 0.9% is allowed, reflecting a tougher stance but demonstrating the impracticalities of a total ban.

In Australia though they do have a zero tolerance standard, so any traces of GM lead to the loss of license.

We might wonder if the organic farmer will win his court case, because how can the GM farm stop their materials blowing in the wind? Can it possibly be the GM farmer’s fault? Well precedence suggests that it might well be, because in a reverse situation contamination has been dealt with.

Just a month ago the US supreme court upheld biotech giant Monsanto’s claims on genetically-engineered seed patents and the company’s ability to sue farmers whose fields are inadvertently contaminated with Monsanto materials.

The high court left intact Monday a federal appeals court decision that threw out a 2011 lawsuit from the Organic Seed Growers and Trade Association and over 80 other plaintiffs against Monsanto that sought to challenge the agrochemical company’s claims on patents of genetically-modified seeds. The suit also aimed to curb Monsanto from suing anyone whose field is contaminated by such seeds.

The case is Organic Seed Growers and Trade Association, et al., v. Monsanto Company, et al. Supreme Court Case No. 13-303 if you would like to look it up, and as I say above one of the aims was to take away the possibility of a farmer being sued for inadvertent contamination, but this aim was not reached. Monsanto state that they have never sued anyone in this position and would not sue any farmer whose farm was found to have less than 1% contamination, and some interpretations suggest that the ruling seems to have made this binding.

It does look as though the contamination issue is causing some headaches for all parties involved.

Now I would like to think about how these rulings intact with other. Let’s take the Australian court case. If the organic farmer wins, other GM farmers will start to worry about their own liability and worry about planting their crops. This might lead to a slow down of the spread of the crops, to the cheer of the organic communities. But it will not help bring about a peaceful co-existence, which is a reality today, so might lead to regulators deciding that their zero policy approach needs a rethink. So maybe they will decide to enact a more US or European stance, and allow a percentage within organic certification, thus relieving the stress from the situation, leading to a more manageable co-existance and possibly aiding the spread of GM products, (probably not the organic farmer’s intended result).

On the other hand, the GM farmer might win, relieving the burden from other GM producers, leading to a more manageable co-existence and possibly also aiding the spread of GM foods.

What actually is GM Food?

Last week I gave some statistics about GM food production both in the USA and worldwide, and this week I wanted to consider what genetic modification actually is. It appears to me that confusion reigns when addressing issues surrounding GM, so I would like to try and clarify a few issues.

GM exists in plants but also in animals as the salmon link showed last week (not currently approved for consumption), but we tend to associate it mainly with crops, so what does it entail?

In relation to the biggest crops that I mentioned last week, soybean, cotton and corn, there are 2 distinctly different approaches. The first is herbicide tolerance (HT) and the second insect resistance (Bt). In other cases nutritional changes have been made, but the major cash crops are based around the following approaches.

Herbicide-tolerant (HT) crops are developed to survive application of specific herbicides that previously would have destroyed the crop along with the targeted weeds. So you can plant your seeds and spray a herbicide that kills everything apart from your desired crop.

Herbicides target key enzymes in the plant metabolic pathway, which disrupt plant food production and eventually kill it. Genetic modification creates a degree of tolerance to the broad-spectrum herbicides – in particular glyphosate and glufosinate – which will control most other green plants.

Industrial Herbicide Techniques

Industrial Herbicide spreading Techniques

1. Glyphosate-tolerant crops
Glyphosate herbicide kills plants by blocking the EPSPS enzyme, an enzyme involved in the biosynthesis of aromatic amino acids, vitamins and many secondary plant metabolites.  There are several ways by which crops can be modified to be glyphosate-tolerant. One strategy is to incorporate a soil bacterium gene that produces a glyphosate-tolerant form of EPSPS. Another way is to incorporate a different soil bacterium gene that produces a glyphosate degrading enzyme.

2. Glufosinate-tolerant crops
Glufosinate herbicides contain the active ingredient phosphinothricin, which kills plants by blocking the enzyme responsible for nitrogen metabolism and for detoxifying ammonia, a by-product of plant metabolism. Crops modified to tolerate glufosinate contain a bacterial gene that produces an enzyme that detoxifies phosphonothricin and prevents it from doing damage.

The developers argue that use of this type of seeds cuts fuel usage and tilling as there are fewer weeds, (tilling leads to top soil loss as it is blown in the wind). They also argue that GM production has led to less herbicide use, and this seems to currently be the case.

Unfortunately one effect of this mass usage seems to be the development of ‘superweeds’, that are becoming resistant to theses herbicides. Farmers have had to address this problem by using more and different types of herbicide, with the journal Nature recently reporting a Pennsylvania State University research article that claims that pesticide use will increase dramatically in the very near future as a result, questioning the sustainability of the process. Something similar to the present antibiotics resistance problem that we are seeing in the human population. It should also be noted that the use of broad spectrum herbicides has grown as GM usage has grown, as its ease of application using the new seeds has made it more widespread, even though it only needs to be applied once.

Insect-resistant crops containing the gene from the soil bacterium Bt (Bacillus thuringiensis) have been available for corn and cotton since 1996. These bacteria produce a protein that is toxic to specific insects. Instead of the insecticide being sprayed, the plants produce the bacteria so the insects eat the plant and die.

There are risks associated with this approach as well as the advantage that farm workers are not exposed to spraying insecticides.

Invasiveness – Genetic modifications, through traditional breeding or by genetic engineering can potentially change the organism to become invasive. Few introduced organisms become invasive, yet it’s a concern for the users.

Resistance to Bt – The biggest potential risk to using Bt-crops is resistance. Farmers have taken many steps to help prevent resistance but as in the previous case it is a potentially serious problem.

Cross-contamination of genes, genes from GM crops can potentially introduce the new genes to native species.

Now I am no scientist as we all know but I presume that the human must consume the bacteria too, although scientists assure me that the bacteria is not harmful to humans or other mammals.

Much of the recent dramatic growth in GM usage can be attributed to the development of plants that offer both of these systems.

Next week I will take a look at the regulation of GM foods.

Blog Action Day 2011

It’s not often we post on a Sunday. In fact I think this is the first time we ever have. The reason for this post is clearly one of high importance then…

UPDATE: I have since discovered that this is our second post on a Sunday, the first being a warning to potential writers about providing copied content – another (although slightly less) important matter.

Every year (for the past four years) on the 15th of October, there is a global Blog Action Day, where bloggers around the world write about one common problem in the world today, in order to try to raise awareness of a pressing issue.

This year the day have been moved back to the 16th of October (today) as that makes it coincide with World Food Day. Unsurprisingly, this years Blog Action Day theme is on food.

A history of Blog Action Day

The first Blog Action Day was held in 2007. The 2007 theme was the environment. At the time, one of the main global concerns (not that it isn’t even more so now) was regarding the sustainability of our current way of life, and the environmental impact, be it global warming, climate change, ecosystem instability or environmental degradation.

The world is in our hands

A green coloured globe represents the environment, which is held carefully in someone’s hands – representing how we control the future of our planet

Blog Action Day took off with a bang with around 20,000 blogs taking part, of which, there were around 20 in Technorati’s top 100 blogs – at the time. This proves that from day 1, Blog Action Day had a big influence, giving it a big potential to actually raise awareness and improve things that it petitions for.

2008 saw an equally important matter being raised: poverty. Poverty is a very pressing issue, and is part of the UN’s 8 Millennium Development Goals which it hoped to meet by 2015.

In 2009 the theme changed to climate change. The phrase ‘global warming’ used to be used before we realised that it wasn’t a very good term, as it’s not just warming that is likely to take place.

The world’s climate is so intricate and complex that you couldn’t say that increase in greenhouse gasses via intensive farming of rice, rearing of cows, burning of fossil fuels, cutting down of rainforests etc. would cause global temperatures to rise, as it wouldn’t necessarily do that everywhere, all the time.

Melting Ice Caps - A Sign of Climate Change

Melting ice caps are a symptom linked to climate change

Hence the term climate change was born in order to supersed the term ‘global warming’ in describing the likelihood of an increase in extreme and irregular weather/climate patterns.

In 2010 Blog Action Day moved onto stressing the importance (and scarcity) of water. Currently most people in the developed world use far more water than should really be available to them, if all water supplies were equally divided.

Only 3% of the world’s water is freshwater, of which the majority is ‘locked up’ in the form of ice. This means that less than 0.007% of all the worlds water drinkable and accessible. This matched with an exponentially rising global population is why over 20% of the world’s population don’t have access to safe drinking water, and one in three people around the world have inadequate sanitation.

One in Five People Don't Have Access to Safe Drinking Water2011 – Food

Now down to matter in hand – Blog Action Day 2011. As I have already mentioned, today is World Food Day, and Blog Action Day’s focus for this year is food.

World Food Day marks the 1945 foundation of the Food and Agriculture Organization, a UN project aimed at achieving food security for all, as well as making sure that people have regular access to enough high-quality, nutritional food, to lead active healthy lives.

Why should we worry about food?

In the words of Blog Action Day’s website:

“We use food to mark times of celebration and sorrow. Lack of access to food causes devastating famines, whilst too much is causing a generation of new health problems. It can cost the world, or be too cheap for farmers to make a living.

The way we companies produce food and drinks can provide important jobs for communities or be completely destructive to habitats and local food producers. Food can give us energy to get through the day or contain ingredients that gives us allergic reactions.

Food can cooked by highly skilled chefs with inventive flair, or mass produced and delivered with speed at the side of road. It can be incredibly healthy or complete junk and bad for your health. It can taste delicious or be a locals only delicacy.

Food is important to our culture, identity and daily sustenance and the team at Blog Action invite you to join us to talk about food.”

Nobody alive today can live without food for more than a month, and a lack of inadequate amounts/types of food can also kill.

Many people don’t realise it, but the greedy ‘Western’ lifestyle is the main reason for food issues around the world. Developed countries are getting too fat, whilst undeveloped ones are not getting enough food. According to the UN, malnutrition kills a child around the world every 15 seconds. That is heart breaking.

Westerners waste so much food, it is disgusting, even more so because of the fact that there are people who don’t have enough of the right foods (or any food at all for that matter) to eat.

How can you help?

If you want to help on a personal level there are two main things you can do.

  1. Try to source as much of your food as locally as you can. This helps local producers, as well as reduced greenhouse emission and water loss from undeveloped countries who use vast amounts of their scarce water to produce food for us. Some global food purchases can be justified, so try to pay attention to where your food is coming from and what the impact of getting it to you is.
  2. Donate to a crisis. There is currently a famine in Eastern Africa, and charities are there to help, but they need your help, be it through voluntary work or capital donations. I an not listing any charities, as it’s often better to decide yourself which ones to support.

You could also blog about the topic. If you have a blog, I wholeheartedly recommend you help to raise awareness yourself. If you read this a day or two late, don’t worry you missed the date, sill write about it and raise awareness. I missed the day last year, but I still blogged about it.

Blog Action Day suggest some topic areas you might like to discuss, which can be helpful if you are not sure where to start.
