Evolutionary breeding, just like weeds

September 2022

Despite all the toxins, genetic devices, and shear physical destruction we throw at them, pests of all kinds continue to thrive in our fields. As climate change imposes all manner of unusual stresses on the environment, farmers and their crops struggle, while pests go from strength to strength.

It's not too difficult to see why. 

Who benefits from alternative proteins?

August 2022


What problem is the burgeoning market for alternative proteins from plant-based meat [1] and cell-based meat [2] trying to solve?

Manufacturers of imitation meat stress that their product is one we can "feel good about". It's healthier, it will solve the rising protein needs of our increasing global population, and it will save the planet from the crippling effects of our unsustainable, greenhouse gas-gushing food system.

The problem presented is the need for more protein-rich food at the same time as the need to reduce the greenhouse gases produced by meat production. We can only solve this contradiction by building factories for mass-produced plant-based and cell-based meat substitutes.

Or, are we being lead up the garden path?

Gene-edited farming - rescue or last straw?

December 2021


Modern 'conventional' farming: too big, too uniform, too much fancy technology, too hype-ridden, and unsustainable.

Paving the way for the acceptance of Westminster's consultation on the regulation of genetic technologies, an opinion piece, written by a top UK crop-pest scientist, was published in the Guardian newspaper. Its headline was:

"Science can rescue farming. Relaxing gene editing rules should be the start"


The villains that farming needs to be rescued from are "new (climate-change driven) plant diseases moving rapidly around the world", and some old plant diseases (such as the blight which caused the Irish potato famine in the 1840s) which still plague us, and the skill and patience required for the long process of conventional plant breeding.

The heroes which will rescue farming are super-fast, precise, trait-specific new crops courtesy of gene editing.

The article also acknowledged that, before farming can be rescued by gene-editing, gene editing will have to be rescued from negative consumer opinion.

Take a step back and look at why our agriculture is being caught so far on the back foot that it needs rescuing.

In old-style 'conventional' plant breeding (a.k.a. 'domestication'), seed is saved, exchanged locally, and possibly selected for planting the following year. The plants evolve* alongside the farmers and everything else which shares their mutual environment. Farmers are producers with key skills in food production, while their naturally genetically-diversified crops evolve into new genetically-diversified crops.

* Note Evolution is an ongoing, ecosystem-wide shifting to new states of equilibrium as all organisms interact with each other and with their non-living environment. "Like all organisms, humans alter the environments around them in ways which have evolutionary consequences" (Mueller and Flachs)

Seventy years of the inappropriately named 'green' revolution have given us new-style 'conventional' (a.k.a. 'traditional') intensively-bred crops which are mainly inbred-hybrids. Such crops have uniform genetics and often include desired traits induced by humans using random mutagenesis (absent safety testing). They are developed off-farm with a prime focus on high yield to supply a globalised market. Key to growing such crops are chemical inputs (fertilisers and pesticides), the cash to buy the inputs and new seed every year, water, and the machines to enable uniform planting, multiple chemical applications, and harvesting on a vast scale. Add to these, government subsidies and an elaborate market infrastructure. Farmers growing them have become consumers of whatever seed, chemicals and machines their suppliers want to flog them.

The green revolution's monocultures and transportation of seeds around the world are big players in the global spread of plant diseases (the ones gene-editing will 'rescue' farming from), and climate change.

The focus on yield, uniformity and scale has long side-lined the nutritional value, taste and sustainability of the crop, and the needs and knowledge of the local people, and evolution. While the on-farm environment keeps changing, just like it always has, industry-supplied inbred-hybrid seed has no capacity for evolution.

The latest shift in agriculture is to crops which have been genetically modified (GM) or gene edited (also GM). These have desired specific traits engineered into them in the laboratory. In a desperate attempt to normalise these GM creations, genetic modification has been absurdly described as "a continuation of the ancient process of (crop) domestication" by which humans "have been manipulating their crops for millennia". Gene-editing takes the public sedation exercise a stage further: it "could happen in Nature" and “allows us to give Mother Nature a helping hand to accelerate the process of evolution". Since all GM traits are bred into existing crops varieties with uniform genetic backgrounds, they are quite clearly nothing to do with old-conventional, evolving, plant breeding and everything to do with new-conventional, non-evolving, green revolution crop production.

Consumers have every reason to be just as uncomfortable with gene editing as they were with genetic modification.

For one thing, there's the science (which isn't difficult to find or to grasp):

  • Apart from the question of functional disturbances in the genome caused by the intended DNA change, there's a mounting body of evidence that the gene editing process itself induces damage elsewhere in the genome [1,2,3].
  • The latest alarming discovery is the possibility that CRISPR gene editing can cause the chromosome to shatter and re-assemble haphazardly, with who-know-what effects on the GM organism.
  • Crop scientists check the success of their genetic engineering by looking for the desired edit at the 'precise location': random wreckage elsewhere remains invisible.

For another thing, as some concerned New Zealand scientists pointed out "the risk of harm from gene technology accumulates over time and scale of production". If Big Biotech gets its way on the scale of gene-tech crops grown all over the world, it's just a matter of time before the risk of harm becomes actual harm.

Then, there's the desperate and unconvincing propaganda such as that described above. As the concerned scientists in New Zealand pointed out, "the risks from technology don't disappear by calling it natural" (and, an edited gene doesn't become natural by calling it evolution).

Suggestions in the crop-pest scientist's article for tackling the public confidence deficit in gene editing include the need for transparency and a 'national debate'. That same month, a letter published in Nature Biotechnology advanced principles for 'Responsible governance of gene editing in agriculture and the environment' which included 'robust, inclusive societal engagement'. Note that no one's suggesting any need for safety testing to reassure the public. What all that transparency, debate and engagement sounds like is a smokescreen for 'educating' the public to want this new-fangled GM food, just like in the 1990s when the first old-style GM crops emerged from the field.

Relaxing gene editing rules' as suggested by the top UK crop scientist translates into a means to avoid safety testing. Indeed, the outcome of the 'consultation' is that UK regulators will now permit field trials of gene-edited crops without risk assessment, and new legislation to exclude gene-edited organisms from the definition of a GMO is now on Westminster's agenda.


OUR COMMENT

The hype surrounding all things GM hasn't changed in quarter of a century. Don't let yourself be 'educated' to think that gene-edited foods will ever be anything but a quick, commercially-lucrative patch shoring up an over-sized unsustainable system with multiple opportunities for harm to health.

The top UK crop scientist acknowledged that "Organic farming has provided us with creative and powerful alternatives for how we grow food" and hints that combining crop 'improvement' using gene-editing with organic methods could be a solution for sustainable agriculture. Obviously giving Mother Nature a helping hand ... and giving the biotech industry an even bigger helping hand while compromising our future organic food supply. Organic farming doesn't need rescued, but it will if genetic engineers get their hands on it.

Ask your MP to take action. Rather than rush simplistic gene edited 'improved' crops to market, the UK government must promote small-scale, diversified, climate-friendly, unadulterated organic, regenerative, and agro-ecological methods that work with nature and put farmers back in the driving seat. In that way, farming might actually rescue itself along with our health, our food supply and our future.

In Scotland, our Environment Minister tells us: 
"Scotland's policy towards GMOs has not changed, and we have no plans for a similar review. As for gene editing, we are disappointed DEFRA would choose to move unilaterally on this. The Scottish Government is committed to keeping aligned with the EU, and we are monitoring the EU's position closely". 
Now is a good time to tell your MSP that you don't trust the new gene technology trajectory of English agriculture and that you fully support Scotland's no GM and no gene editing policy.

Doing the maths of bacterial burgers

November 2021

Do the sums of farm-free food fermented in the desert as the saviour of our over-heating planet really add up? [1].

The big why of fake food

November 2021


 

If you've just been reading about the plan to save the world by feeding people very strange burgers grown in vats on even stranger buns so that all the land we've destroyed with agriculture can be left to re-wild [1], you may well be asking yourself some 'why' questions.

Why would we consider junking the entire historic basis of human provisioning?

Why, when we're already suffering unprecedented chronic disease from our novel, over-processed, corporate-led diet, would we head off down a path which takes all these aspects to new extremes?

Why, when millions go hungry due to poverty, bad cultural influences and bad politics, are we concentrating on technofixes to our food chain?

Why, when there are more farmers in the world than in any other single job, would we scrap farming?

Impossible, incredible, awesome, beyond...

January 2020


'... common sense?

The 'Impossible' bleeding plant burger started out back in 2017 as textured wheat protein with fake soyabean 'blood' from GM yeast and some other stuff collectively described by its manufacturer, Impossible Foods, as "simple, all-natural ingredients" [1]. By 2019, Impossible Foods had realised their Impossible burgers weren't sufficiently beef-like and were unpopular with the gluten-intolerant sector of the population. The non-meat burgers were accordingly re-formulated with soya protein.

It seems, however, that sourcing sufficient quantities of affordable non-GM soya to suit its clean, green image and marketing aspirations proved impossible: Impossible Foods' answer was to switch to cheap and plentiful GM soya and hype its way out of the image problem [2].

Insectageddon

April 2019

"... having taken every step science can offer to devitalise the soil and its food that supports him, (man) is now turning his attention to destroying the insect world upon which he is also dependent." ... "... if birds eat insects poisoned by (pesticides) this can kill them - a striking tribute to the intelligence of 'scientists', since birds are our best safeguard against pests." (Easterbrook, 1946)
Green MEP, Molly Cato, describes how she has lost count of the times she has debated the "Armageddon" we are inflicting on our environment, only to be met with "patient, patronising smiles" from fellow MEPs and no action.

The quote above comes from a 1946 article and refers to DDT and other contemporary "powerful insecticides of which far too little is yet known". The author goes on to liken those humans intent on spreading pesticides through their own environment to "schoolboys rat-hunting in a munitions dump with a flame thrower".

Note. DDT was the first modern synthetic insecticide. Its insecticidal properties were discovered in 1939 and it was quickly adopted by the military in World War II to protect the troops. The scientists who identified DDT's pesticidal potential won the Nobel prize for it. DDT has been poisoning the world ever since.

Since then, we've had decades of the Green Revolution inflicting chemical after chemical on our world, and now we have GM crops specially designed for greater chemical applications, and even for producing their own.

Take horizontal gene transfer seriously - now

February 2019


The risk to health from artificial antibiotic resistance genes being used as markers during the creation of most GMOs was recognised in Europe back in the 1990s. However, lulled by mathematical modelling suggesting horizontal gene transfer (HGT) would never be significant in a complex, natural environment, the problem wasn't taken too seriously [1].

USA missing the main markets

October 2018


America has been gung-ho about declaring gene-edited plants somehow not really GM, paving the way for the new-GM crops now lining up for entry to the US food market [1,2].

The back-drop to this is interesting.

The dicamba conundrum

July 2018

Despite the host of problems presented by the expanded use of dicamba herbicide last year [1], the US Environmental Protection Agency (EPA) has cut a deal to allow the chemical's continued application. Monsanto was "very excited" by the EPA's decision.

This excitement isn't surprising because dicamba is vital to the Company's next generation of GM soya. Now that weed resistance to Roundup is rendering Monsanto's Roundup Ready GM soya obsolete, future fortunes are depending on dicamba tolerance technology as a replacement.

70% of world's population fed by peasant farmers

February 2018

Of all our modern 'conveniences', the invention of the Industrial Food Chain must rank as the most unfit-for-purpose.

The Chain has a beginning, a middle and an end:
  • The beginning is all the resources needed for monoculture of crops: hybrid seed, large tracts of flat land, plentiful water, machines (plus the fossil fuels needed to manufacture and run them), and agrichemicals (plus the fossil fuels needed to manufacture and apply them)
  •  the middle is transport, storage, processing, packaging and retailing, all of which require an infrastructure of facilities and machines (plus the fossil fuels needed to create and maintain them) 
  • The end is the food in your kitchen, profit here and there along the way, and wasted stuff. 
Like all chains, the Industrial Food Chain is only as strong as its weakest link. Unlike all chains, every one of The Chain's links is weak.

Scotching the GM myth

December 2017

'Food security' is a complex problem for which simple solutions have long been tried, and as long have failed. In fact, 'food security' isn't even easy to define.

Prior to the 1980s, the problem seemed straightforward: just add together all the food produced in the area of interest, add net food imported, and divide the total by the number of people living there. If there were enough calories available per person, the area was 'food secure'.

Corporate Communism?

November 2017

Denying local communities the freedom to choose their own agricultural system, not only what they grow but how they grow it, has suddenly become a priority in the USA.

By August this year, 28 States had passed "seed pre-emption laws" never deemed necessary nor desirable before.

The new laws are primarily designed to block counties and cities from banning GMOs, but the language used in some bills could enable them to extend to such things as manures, fertilisers and irrigation (these could be used to promote, for example, agri-chemical corporate interests, agri-chemical dependent GM crops, and futuristic drought-tolerant GM crops).

Dicamba and dust

October 2017

The major herbicidal chemicals used by US farmers haven't really changed very much over the decades. Various forms of 'dicamba', first introduced in 1967, and 'glyphosate', first introduced in 1974 , feature in America's agricultural landscape as much today as they did a quarter of a century ago.

Both these herbicides have a low acute toxicity to animals (you'd need to eat an awful lot before you'd drop dead). However, their properties, modes of action and applications are very different.

Dicamba selectively kills broad-leafed weeds, but not grasses. In 1994, 90% of the 27.6 million pounds of dicamba formulation used in US fields was applied to maize.

Glyphosate kills all plant life. Until the late 1990s, glyphosate was used to clear the ground before a crop was planted, and in 1995 27.6 million pounds of glyphosate-based weedkiller was used in US fields. Since then, usage has increased some fifteen-fold due to widespread planting of GM glyphosate-tolerant soya and later several other similarly-engineered major crops.

In a bizarre twist of fate, glyphosate's popularity has led to a "battle between farmers" and even a farmer's murder, caused by dicamba.

Crop diversity disaster

September 2017

"It is agronomically, ecologically, nutritionally, and economically risky and unsustainable to rely almost exclusively on a handful of major crops to provide food for the world's (future population)" (Dempewolf).

The 'agronomic' problem is the need for crop diversification to achieve adaptation and resilience of our food production systems in the face of climate change.

The 'ecological' problem is that monocultures are an unbalanced hole in the ecosystem which can generate disease and spread toxins.

The 'nutritional' problem is that a diverse and varied diet is vital for our nutrition and health.

The 'economic' problem stems from all of the above.

Scotland's food industry at risk

September 2017
Scotland's renewed vulnerability to GM-by-force has been highlighted by our Rural Economy Secretary, Fergus Ewing.

Scottish produce has an excellent reputation around the world.  Food and Drink export is one of the standout success stories in our economy in terms of jobs and growth.  Earlier this year, the Scottish Government launched ‘Ambition 2030': an ambitious plan to target export markets for growth over the next 3 years that, if successful, will more than double the current turnover of our country's food and drink sector.  The outcome will make Scotland a model of responsible, profitable growth.

In 2015, Scotland requested exemption from EU consents for the cultivation of GM crops. This 'opt-out' is extremely important for our £5.5 billion food and drink industry.

After Brexit, Scotland's 'opt-out' will no longer be in force and we'll be at the mercy of whatever GM whim Westminster chooses to impose on us.

GM trees on the march

July 2017

GM trees are coming on in leaps and bounds.  The fruit of the Arctic Apple-tree is making its appearance in American Midwest stores [1], but the big GM tree event is 'short-rotation woody crops'.

Short-rotation woody crops are fast growing trees which can be harvested in just a few years for industrial purposes such as paper and biofuels.  Eucalyptus, which escaped from its native Australia when Captain Cook arrived there, has become one such major crop since the 19th Century.  Because different species are adaptable to many local climates, plantations are now found on every continent.  The next wave, just beginning to gain momentum, is GM eucalyptus.

Pesticides' catastrophic impacts

May 2017

In March this year, the United Nation (UN) special rapporteurs on the right to food and on toxics presented a scathing report on pesticides.

It pointed to the "catastrophic impacts (of pesticides) on the environment, human health and society as a whole", including an estimated 200,000 deaths a year from acute poisoning alone, plus untold suffering from chronic pesticide exposure now linked to "cancer, Alzheimer's and Parkinson's disease, hormone disruption, developmental disorders and sterility".

NFU admits farmers must grow what consumers want

The Vice President of the National Farmers Union (NFU), who "thinks GM is the way forward" and that science, not "popular appeal", should be directing what farmers can and can't grow, has finally admitted he has to be "mindful of markets". He's noticed that he has to "grow what consumers want to eat" or what he grows won't sell.

Attendees at a meeting of United Oilseeds (co-operative specialist oilseeds merchant) were warned:
"If the UK takes a pro-GM attitude, where are our exports going to go? If we start to develop a different policy to the rest of the EU, those issues (product marketability) will raise their heads and we need to be very, very careful".
Add to this that there is a need for regulators "to recognise that agriculture is not just like any other industry" and that "some level of self sufficiency, some level of food security, is a political objective. Our home agriculture needs to thrive".

Feeding disease

December 2016

In 1973, the US Farm Bill was passed to assure a plentiful supply of staple foods at reasonable prices. The 'staples' are corn, soya, wheat, rice and sorghum, all subsidised by the US tax-payer.

Forty years on, US farmers planted maize over an area almost as big as California, and the area growing soya isn't far behind.

Prices for these commodities have been low in recent years, perilously close to their costs of production. Yet, courtesy of the government, they have been the safest bet for the growers of the vast fields of American monocultures.

How these subsidised 'staple food' crops are streamed into the market is a lesson in itself .
