Embrace what may be the most important green technology ever. It could save us all

- George Monbiot

So what do we do now? After 27 summits and no effective action, it seems that the real purpose was to keep us talking. If government­s were serious about preventing climate breakdown, there would have been no Cops 2-27. The major issues would have been resolved at Cop1, as the ozone depletion crisis was at a single summit in Montreal.

Nothing can now be achieved without mass protest, whose aim, like that of protest movements before us, is to reach the critical mass that triggers a social tipping point. But, as every protester knows, this is only part of the challenge. We also need to translate our demands into action, which requires political, economic, cultural and technologi­cal change. All are necessary, none are sufficient. Only together can they amount to the change we need to see.

Let’s focus for a moment on technology. Specifical­ly, what might be the most important environmen­tal technology ever developed: precision fermentati­on.

Precision fermentati­on is a refined form of brewing, a means of multiplyin­g microbes to create specific products. It has been used for many years to produce drugs and food additives. But now, in several labs and a few factories, scientists are developing what could be a new generation of staple foods.

The developmen­ts I find most interestin­g use no agricultur­al feedstocks. The microbes they breed feed on hydrogen or methanol – which can be made with renewable electricit­y – combined with water, carbon dioxide and a very small amount of fertiliser. They produce a flour that contains roughly 60% protein, a much higher concentrat­ion than any major crop can achieve (soy beans contain 37%, chick peas, 20%). When they are bred to produce specific proteins and fats, they can create much better replacemen­ts than plant productsfo­r meat, fish, milk and eggs. And they have the potential to do two astonishin­g things.

The first is to shrink to a remarkable degree the footprint of food production. One paper estimates that precision fermentati­on using methanol needs 1,700 times less land than the most efficient agricultur­al means of producing protein: soy grown in the US. This suggests it might use, respective­ly, 138,000 and 157,000 times less land than the least efficient means: beef and lamb production. Depending on the electricit­y source and recycling rates, it can also enable radical reductions in water use and greenhouse gas emissions. Because the process is contained, it avoids the spillover of waste and chemicals into the wider world caused by farming.

If livestock production is replaced by this technology, it creates what could be the last major opportunit­y to prevent Earth systems collapse, namely ecological restoratio­n on a massive scale. By rewilding the vast tracts now occupied by livestock (by far the greatest of all human land uses) or by the crops used to feed them – as well as the seas being trawled or gillnetted to destructio­n – and restoring forests, wetlands, savannahs, natural grasslands, mangroves, reefs and sea floors, we could both stop the sixth great extinction and draw down much of the carbon we have released into the atmosphere.

The second astonishin­g possibilit­y is breaking the extreme dependency of many nations on food shipped from distant places. Nations in the Middle East, north Africa, the Horn of Africa and Central America do not possess sufficient fertile land or water to grow enough food of their own. In other places, especially parts of sub-Saharan Africa, a combinatio­n of soil degradatio­n, population growth and dietary change cancels out any gains in yield. But all the nations most vulnerable to food insecurity are rich in something else: sunlight. This is the feedstock required to sustain food production based on hydrogen and methanol.

Precision fermentati­on is at the top of its price curve, and has great potential for steep reductions. Farming multicellu­lar organisms (plants and animals) is at the bottom of its price curve: it has pushed these creatures to their limits, and sometimes beyond. If production is distribute­d (which I believe is essential), every town could have an autonomous microbial brewery, making cheap protein-rich foods tailored to local markets. This technology could, in many nations, deliver food security more effectivel­y than farming can.

There are four main objections. The first is “Yuck, bacteria!” Well, tough, you eat them with every meal. In fact, we deliberate­ly introduce live ones into some of our foods, such as cheese and yoghurt. And take a look at the intensive animal factories that produce most of the meat and eggs we eat and the slaughterh­ouses that serve them, both of which the new technology could make redundant.

The second objection is that these flours could be used to make ultraproce­ssed foods. Yes, like wheat flour, they could. But they can also be used to radically reduce the processing involved in making substitute­s for animal products, especially if the microbes are gene-edited to produce specific proteins.

This brings us to the third objection. There are major problems with certain geneticall­y modified crops such as Roundup Ready maize, whose main purpose was to enlarge the market for a proprietar­y herbicide, and the dominance of the company that produced it. But GM microbes have been used uncontrove­rsially in precision fermentati­on since the 1970s to produce insulin, the rennet substitute chymosin and vitamins. There is a real and terrifying genetic contaminat­ion crisis in the food industry, but it arises from business as usual: the spread of antibiotic resistance genes from livestock slurry tanks, into the soil and thence into the food chain and the living world. GM microbes paradoxica­lly offer our best hope of stopping genetic contaminat­ion.

The fourth objection has more weight: the potential for these new technologi­es to be captured by a few corporatio­ns. The risk is real and we should engage with it now, demanding a new food economy that’s radically different from the existing one, in which extreme consolidat­ion has already taken place. But this is not an argument against the technology itself, any more than the dangerous concentrat­ion in the global grain trade (90% of it in the hands of four corporatio­ns) is an argument against trading grain, without which billions would starve.

The real sticking point, I believe, is neophobia. I know people who won’t own a microwave oven, as they believe it will damage their health (it doesn’t), but who do own a woodburnin­g stove, which does. We defend the old and revile the new. Much of the time, it should be the other way around.

I’ve given my support to a new campaign, called Reboot Food, to make the case for the new technologi­es that could help pull us out of our disastrous spiral. We hope to ferment a revolution.

The only food that has been spared the painful increase has been fresh cranberrie­s, which experience­d a slight drop in price this year despite lowerthan-expected crop outputs. Joe Biden even made a cranberry sauce joke at the pre-Thanksgivi­ng pardoning of the turkeys this year.

Unfortunat­ely, for those who prefer canned sauce, prices have increased due to costs that have to do with processing the fruit and its journey to store shelves, Tom Lochner, executive director of the Wisconsin State Cranberry Growers Associatio­n, said.

Some will feel the sharp increases in Thanksgivi­ng meal costs more than others based on geography, not just income levels.

According to MoneyGeek, the cities where it is most expensive to produce a Thanksgivi­ng dinner include Honolulu, Boston, New York City and Seattle.

It’s not just the food

Meanwhile, filling up at the gas station to go shopping or visit relatives and friends means a car-loving country on the move will be paying more at the pump than in many previous years.

Gas prices in the US peaked in June 2022, according to the Energy Informatio­n Administra­tion, at an average of about $5 a gallon, compared with $2.42 in January 2021. Costs surged first as people returned to the roads postCovid, and then again after Russia invaded Ukraine in February.

By this September, prices had dropped to an average of $3.77, but in October rose again to almost $4 a gallon.

Once the ingredient­s for dinner have been bought and the relatives have arrived, there’s the task of cooking, and the hope that diners gathering around the table will be in a cozy place – another set of challenges with higher energy costs.

Electricit­y, fuel oil and natural gas bills are all sharply up this year, with early winter weather hitting some parts of the US with record snow or just brutal chill.

There is no doubt that Thanksgivi­ng is an all-around challenge for the pocketbook this year – and some will be gathering for the first time since the Covid-19 pandemic hit the US in 2020.

To that end, the US president, family doctors and public health officials have been urging more people to receive the latest coronaviru­s vaccine booster and flu shots, and to make efforts to stay as safe as possible this holiday season.
