Another day, another lawsuit against global seed and chemical giant Monsanto Corporation. In a complaint filed Tuesday in federal court in Wisconsin, six consumers alleged that the company’s top-selling Roundup herbicide has been falsely promoted as uniquely safe when it actually can have profound harmful impacts on human gut bacteria critical to good health.

The lawsuit, which also names Roundup distributor Scotts Miracle-Gro Co. as a defendant, specifically alleges that consumers are being deceived by inaccurate and misleading statements made by Monsanto regarding glyphosate, the active weed-killing ingredient in Roundup.

Plaintiffs include residents of Wisconsin, Illinois, California, New York, New Jersey and Florida.

Glyphosate, which Monsanto introduced as an herbicide in 1974 and is widely used in growing food crops, has been promoted for years as a chemical that kills plants by targeting an enzyme that is not found in people or pets.

The lawsuit claims that assertion is false, however, and argues that research shows glyphosate can target an enzyme found in gut bacteria in people and animals, disrupting the immune system, digestion, and “even brain function.”

“Defendants repeat these false and misleading representations throughout their marketing, including in video advertisements produced for their websites and YouTube Channel,” states the lawsuit, which is filed in U.S. District Court for the Western District of Wisconsin.

Monsanto did not respond to a request for comment and neither did Scotts.

Monsanto is currently defending itself against nationwide claims that Roundup has caused hundreds of people to suffer from a type of blood cancer called non-Hodgkin lymphoma (NHL).

More than 1,100 plaintiffs have lawsuits pending in state and federal courts with many of the lawsuits combined in multidistrict litigation in federal court in San Francisco.

Those lawsuits were triggered by a 2015 decision by the World Health Organization’s International Agency for Research on Cancer (IARC) to classify glyphosate as a probable human carcinogen.

IARC said research showed an association between NHL and glyphosate, with limited evidence from epidemiology data collected on humans and stronger evidence seen in laboratory animals exposed to glyphosate.

The lawsuit filed in Wisconsin is markedly different from the Roundup cancer claims, though some of the same attorneys are involved in both lines of litigation.

Plaintiffs do not claim physical injury; rather they claim violations of trade and business practices laws, and allege Monsanto and Scotts were “unjustly enriched” as plaintiffs purchased and paid for more Roundup products than they would have in absence of the alleged false promotions.

Good, Good, Good, Good Bacteria

SUBHEAD: Fermented foods are healthy low-energy users – they require no cooking or refrigeration.

Recent research on the role of bacteria suggests we need a radical rethink about what makes us healthy. Thanks to advances in genetic sequencing, scientists are starting to discover, categorise and understand the importance of the vast universe of microbial organisms that live invisibly on, in and around us.

In May, results from studies conducted by Tim Spector, professor of genetic epidemiology at King’s College London, showed that a ten-day diet of junk food caused the loss of 1,300 species of beneficial bacteria in the intestines. Professor Spector said: “Microbes get a bad press, but only a few of the millions of species are harmful, and many are crucial to our health.”

Instead of bacteria being our deadly foe, it turns out the vast majority are really our best friends – and our oldest. According to the Human Microbiome Project, our ‘live-in’ molecules – the single cell organisms including bacteria and fungi that are neither plant nor animal but in a category of their own – have evolved symbiotically with us and our pre-historic ancestors since time began.

Like the best of relationships, we are inter-dependent. We provide energy via food to our single-cell friends: in return they perform a myriad of life-giving activities.

As it is in our gut, so it is in the soil. The idea articulated by SFT director Patrick Holden that healthy topsoil thrives because of microbial activity – functioning in a similar way to human digestion – illustrates the interconnectedness of everything. In the dark of topsoil, microscopic microbes perform vital tasks to maintain the health of soil life. Meanwhile, in the dark of our digestive system, trillions of tiny microbes are likewise busy keeping our bodies healthy.

The role of beneficial bacteria is multi-functional. A key role of both soil and gut bacteria is digestion. These beneficial bacteria break down nutrients into digestible forms that can be assimilated by the plant’s roots, or the gut lining in our intestines, enabling both plants and humans to thrive. As well as bacteria being an essential component of digestion, beneficial bacteria also help to repel disease and are a key component of a healthy immune system.

The number of microorganisms living invisibly in the world is mind-boggling: one teaspoon of rich garden soil can hold one billion bacteria along with fungi and other microorganisms. As for the bacteria in a symbiotic relationship with us, the majority live in the walls of our intestines. This community of diverse bacterial species, called the gut microbiome, weighs about two kilos.

There is a clear analogy between soil and human digestion and, according to nutritionist and author Daphne Lambert, there is also a direct relationship. In her soon-to-be-published book Living Food: A Feast of Soil and Soul, she traces the origins of soil eating for health, drawing on recent studies to argue for increased exposure to soil to build immunity.

She writes, “Today our food industry kills off these organisms and together with our excessively clean households this means few if any of these soil-based organisms manage to find their way into the human digestive system.”

According to Lambert there is evidence to suggest that the ingestion of soil-based organisms from a vibrant, healthy soil enhance the functioning of our gastrointestinal tract. But our modern lifestyles break the link between healthy soils and healthy humans, with less people than ever before working on the land and every last trace of soil washed off the vegetables we buy.

But what about the scary bugs? Small children are naturally drawn to soil but it’s usually us adults who start freaking out about the dirt. Take heart that the benefit of handling soil far outweighs the risks. First, the good bacteria outnumber the bad. Second, we develop the capacity to deal with the bad ’uns by the very practice of being exposed to microbes in the first place.

First proposed in 1989, the hygiene hypothesis in medicine shows that we do small children a disservice by keeping them in a sterile environment. Getting down and dirty is how our immune system learns to defend us from disease.

Children who develop healthy immune systems in this way will doubtless be better able to resist infections. However, a word of caution: a great deal of our soil has had its inherent health degraded by intensive agricultural methods and intensive farms can be breeding grounds for dangerous bacteria such as E.coli O157, so hand washing hygiene is called for in some situations.

Ideally, we should be able to ditch our antibacterial cleaners too. Rather than obliterating all bacteria, we could take a leaf out of traditional Asian cultures and clean our houses with a fermented solution of probiotics that feeds good bacteria, which then eat up the bad smells, dirt and grease caused by harmful bacteria.

Yet, in our spoiled and imperfect world there will be exceptions here too, and caution is needed, especially when preparing chicken, which is so often a source of campylobacter infections.

Good bacteria in food
Just as we can colonise our homes and soil with good bacteria, so we can restore health to our gut.

When it comes to the human diet, nutritional therapists commonly agree that the best way to create good gut bacteria via what we eat is to eat more as our ancestors ate and adopt a three-step approach: reduce sugar, raise fibre and eat fermented foods.

Take sugar first. Or rather don’t! Bad bacteria feed on sugar and they start complaining when they don’t get it. Based on a review of recent scientific literature, US researchers found that gut microbes may cause us to crave the very nutrients they need to grow, by releasing signaling molecules into our system.
You can diminish bad bacteria by giving your good bacteria a boost with prebiotics, or fibre on which good bacteria feed. As Lambert explains:
“The intestine lacks the enzymes necessary to break down oligosaccharides so they move through to the colon where they serve as food for beneficial existing bacteria so they grow and multiply, squeezing out bad bacteria. Oligosaccharides are found in many foods but there is a major one for each season: onions in winter, asparagus in spring, leeks in summer, and Jerusalem artichokes in autumn. Nature really has got it right.”
Finally, fermented foods are important. Bacteriology may be in its infancy, but, according to author and food campaigner Michael Pollan, every traditional food culture has fermented food in its diet. Think sauerkraut, chocolate, tamari and kimchi.

“Fermented foods not only produce amazing tastes, they also increase nutrients,” says Lambert, who also runs fermentation workshops. “Growing colonies of microbial cultures makes nutrients more available, and also increases them, including vitamins and especially Vitamin B.”

Fermented foods are low-energy – they require no cooking or refrigeration. By preserving summer foods throughout long winters or saving food from decomposition in tropical heat, humans have survived inhospitable climates. Captain Cook famously took sauerkraut (fermented cabbage) to reduce scurvy on his sea voyages.

Most bacteria are notoriously hard to culture in a petri dish, so our knowledge of bacteria’s many uses is still severely limited. One of the most widely known bacteria is Lactobacillus acidophilus – the Latin for acid-loving milk bacterium – which predigests food, transforming, for instance, milk into yogurt.

“The more foods you eat that aid digestion the better, and in many cases these foods are beneficial because of bacteria,” says Lambert. “It is about understanding our relationship with bacteria – not annihilating them. By declaring war on bacteria, we are declaring war on life itself.”

Currently being crowdfunded at Unbound, Living Food: a Feast for Soil and Soul celebrates a gastronomy that is good both for human and planetary health. The following extract features two recipes from a collection of more than 70.

Fermented vegetables
Cabbage is cheap to buy. Once fermented, it adds complex and delicious flavours – one of the joys of life.

Sauerkraut
3 medium-size white cabbage heads (about 2 kilos)
1 four-litre clean glass jar
2–3 tablespoons sea salt
Shred the cabbage and place it in a large metal bowl. Sprinkle over one tablespoon of salt and pound gently with a wooden rolling pin to help pull the water out of the cabbage. Cover with a cloth and leave overnight. The next morning, place about two inches of cabbage into the glass jar and press firmly down, sprinkle with a little salt and repeat until the jar is full. As you layer up you can add spices and herbs to flavour.

Firmly compress the layers of cabbage. Place a weight on top like a jam jar filled with water to make sure the cabbage is completely submerged by the brine (if necessary add a little water). Cover with a cloth to protect from flies. Every day, push the cabbage gently down. Let the jar sit at room temperature. After a week the cabbage has fermented sufficiently to be eaten, but you can leave it for a further couple of weeks. If you are not going to eat the cabbage straight away, fit with a lid and store in a cool, dry place where the tangy flavour will continue to develop. Once you start eating the cabbage, keep it in the fridge.

Fermented grains
Many grains in different parts of the world are made more digestible through fermentation: in Japan the soya bean is fermented into traditional fermented foods such as tempeh, soy sauce and miso.

In Africa, millet is fermented for several days to produce a sour porridge called ogi, and in India rice and lentils are fermented for at least two days before making idli and dosas. Corn was fermented before using in Mexico, and throughout Europe grains used to be soaked overnight in soured milk ready to make porridge in the morning.

It’s very easy to start soaking grains and this simple process is an enormous aid to digestion. Soak your chosen grain in water for a minimum of eight hours at room temperature. You can assist the process by adding a little fermented (sauerkraut) vegetable juice or yogurt.

Fermented whole oat porridge
By fermenting the whole oat grouts before cooking, the flavour of the porridge is enhanced, the grains are more digestible and there is greater nutrient bioavailability.

Place oat grouts (whole oats) in a bowl, just cover with water and leave at room temperature for two days. You can leave for longer if you choose to create a more intense acidic flavour. To assist the process, add a tablespoon of sauerkraut juice, apple cider vinegar or kefir to the water.

Strain the oats, saving the soak water, then simply eat the grains as they are with soaked nuts and seeds and seasonal fruits. Alternatively, you can cook the grouts, either in the soak liquid or fresh water, depending on your flavour preference. Gently heat the oats and cook very slowly until thick and creamy. Add a pinch of salt and serve with whatever you fancy.

Leaf Cutters

SUBHEAD: The problem is the solution. Damaged soils is a problem. Natures solution is to send leaf cutter ants.

Image above: Leaf cutter ants marching to nest carrying sections of leaves. From (http://www.optibacprobiotics.co.uk/blog/2013/09/leaf-cutter-ants-carry-friendly-bacteria).

We are up river in Belize at the Maya Mountain Research Farm these next two weeks, teaching our tenth annual Permaculture Design Course here. This year we have 16 local Mayan farmers, healers, businessmen and women, trainers in development work, and students from the US, UK, Russia and Greece. Our own essay this week, about a different topic, is being guest-published at Club Orlov on Monday, so we thought we would publish here a short piece by our host, Christopher Nesbitt.

This is a small nest of a leaf cutter ant queen, establishing a colony. We tend to see them in tired land, rebuilding soils, assaulting the biological obscenity of monoculture, especially citrus, and aerating soils, hauling carbon down to the subsoil, allowing oxygen and water to infiltrate soils.

They will do some damage to native species, like cacao, but mostly concentrate on introduced species. Chemicals are not a constant necessity. I have been farming in a tropical setting since 1988, and I have NEVER used any biocides.

I am farming about 15 acres of a 70 acre piece of land. Most of the land I am working right now is old cattle pasture or abandoned citrus. You would not be able to tell looking at it. I live in a pretty lush forest of trees, with hundreds of species. Most of what I am doing is creating a stacked polyculture with a large diversity of species, ranging from banana, papaya and pineapple, to timber, to fuel wood, to tree legumes, to food, to medicinals and market crops that fit into the matrix of the farm, things like cacao, coffee and vanilla.

We do have some gardens, and we are expanding on the periphery of the land to create coconut dominated polycultures and feed banks for pigs, but the majority of the farm resembles the primary rainforest in structure, with less diversity, and with all the species being selected by us. We get both termites and leaf cutter ants. While they can both be a nuisance, if we step back a bit, we can see some of the services and products they provide.

Think of the presence of leaf cutter ants as being an indicator of an ecosystem out of balance, of being a cure for damaged soils. The lack of leaf cutter ants may mean a healthy ecosystem, or massive use of chemicals, including aldrin. I think of leaf cutter ants as being nature's way of rehabilitating damaged soils.

You really only see leaf cutters in the wake of a biological catastrophe, hurricanes, fire damaged land, or places like played-out milpa, after the window of 3-6 years of annuals productivity has dwindled out, and the return on energy invested is not worth the effort, and the land in question is being fallowed, or in the wake of the life of a citrus grove, abandoned banana plantations or damaged cattle pasture.

Most biological "catastrophes" are man made, with monocultures being the biggest biological catastrophe, sustained through work and inputs. These systems are only sustainable in simplistic economic models of capital invested in input and labor versus kilograms per hectar x dollar per kilogram.

Often, in terms of calorie based accounting, they are net losses of energy. Without cheap petroleum to subsidize their profitless existence, they would not exist.

I have lots of leaf cutter ants here in Belize, and while they can be a nuisance, they seldom damage a tree beyond the capacity of recovery. The biggest problem is that, if one is looking to produce marketable quantities of a single species, you have painted a sign on your ass that tells nature "bite me." Nature obliges.

While working industriously to undo the biological abomination of a monoculture the ants are the rescue squad, aerating the soil, allowing water to percolate in, and hauling carbon, all things that help damaged soil to recover.

Monocultures lead to leaf cutter ants. Leaf cutters have adapted to citrus in particular, with a preference for Washington navels and Valencia oranges. They are less excited by grapefruit or limes. What we call Jamaica lime here in Belize is practically immune to leaf cutter ants (and tolerates poor soil).

One way to avoid leaf cutters is to have a diversified farm in the first place, but any young polyculture in the lowland humid tropics is going to be prone to leaf cutter ants. When the land is more mature, it will be less susceptible, but not immune.

We see a lot of leaf cutter nests. I periodically dig up the mounds, looking for their fungus gardens, the subterranean chambers where they use the leaves for a substrate for their fermentations. When the young flightless queens are in the embryonic stage, they are like milk shakes for chickens. Even whacking on the surface of the nest will excite the colony.

Ants, being social insects, react to any perceived threat to the queen by swarming. Any disturbance on ground level will result in massive retaliation by the soldier ants, which are like micro pit bulls.

My chickens have visually imprinted on soldier ants and queen ants as being food. Soldier ants come out, looking to attack the source of the disturbance, and chickens happily eat them, racing about to snatch them up, converting a problem into eggs, meat and manure. I invest a bit of energy in harassing the colony, and the result is a smorgasborg of insect protein for my chickens. I have eliminated a few nests with this technique.

You can also make barriers of lemon grass, or vetiver, which leaf cutter ants do not like, lay cannavalia ensoformis leafs in their trails, which has antifungal properties and eventually, accidentally, will be taken into their nest, working better than a Stuxnet virus. If I put the soil from one nest across the trail of another nest they will not cross the trail (for a while). All of these are more about management than destruction.

The important thing is to see the inherent limitations of sustainably managing your farm. Certain crops are leaf cutter ants' favorite foods. If you want to grow citrus, you need to walk your land regularly, looking for new nests. How much land can a farmer adequately monitor? When you find a new nest, you must dig it up and find the queen, and kill her. I find a certain spiteful glee of throwing the helpless queen out into a flock of chickens, and watching them fight over her.

If the colony is young enough that it has no capacity to requeen itself, you have killed the colony. If not, you will need to dig it several times to kill the colony. Sometimes, its just going to be there. In Costa Rica and Panama, I hear they use pig manure to discourage the leaf cutter ants, pouring in a foul slurry into their home.

The key is to have a diversified system whereby you can use that energy in a useful way. Without poultry, we would have little use for either leaf cutter ants or for termites. With them, they both become assets.

Industrial mentality: the solution is the problem. Have leaf cutter ants. Apply biocide. Poison soil, water, self. Support nasty earth destroying chemical company.

Permaculture mentality: The problem is the solution. Damaged soils is a problem. Natures solution is to send leaf cutter ants. Leaf cutter ants are a problem. My solution is to use them to solve another problem, what to feed our chickens.
