‘Green growth’ doesn’t exist – less of everything is the only way to avert catastrophe
George Monbiot (The Guardian)
It is simply not possible to carry on at the current level of economic activity without destroying the environment.
There is a box labelled “climate”, in which politicians discuss the climate crisis. There is a box named “biodiversity”, in which they discuss the biodiversity crisis. There are other boxes, such as pollution, deforestation, overfishing and soil loss, gathering dust in our planet’s lost property department. (...)
Nature recognises no such divisions. As Earth systems are assaulted by everything at once, each source of stress compounds the others.
Take the situation of the North Atlantic right whale, whose population recovered a little when whaling ceased, but is now slumping again: fewer than 95 females of breeding age remain. (...)
Studies of bees show that when pesticides are combined, their effects are synergistic: in other words, the damage they each cause isn’t added, but multiplied. When pesticides are combined with fungicides and herbicides, the effects are multiplied again. (...)
When rainforests are fragmented by timber cutting and cattle ranching, and ravaged by imported tree diseases, they become more vulnerable to the droughts and fires caused by climate breakdown.
What would we see if we broke down our conceptual barriers? We would see a full-spectrum assault on the living world. Scarcely anywhere is now safe from this sustained assault. A recent scientific paper estimates that only 3% of the Earth’s land surface should now be considered “ecologically intact”.
The various impacts have a common cause: the sheer volume of economic activity. (...)
When we box up this predicament, our efforts to solve one aspect of the crisis exacerbate another. For example, if we were to build sufficient direct air capture machines to make a major difference to atmospheric carbon concentrations, this would demand a massive new wave of mining and processing for the steel and concrete. (...)
Or look at the materials required for the electronics revolution that will, apparently, save us from climate breakdown. Already, mining and processing the minerals required for magnets and batteries is laying waste to habitats and causing new pollution crises. Now, as Jonathan Watts’s terrifying article in the Guardian this week shows, companies are using the climate crisis as justification for extracting minerals from the deep ocean floor, long before we have any idea of what the impacts might be. (...)
But there is no such thing as green growth. Growth is wiping the green from the Earth.
We have no hope of emerging from this full-spectrum crisis unless we dramatically reduce economic activity. (...) Sustaining our life-support systems means doing less of almost everything. But this notion – that should be central to a new, environmental ethics – is secular blasphemy.

In this counter-current operation, there are initiatives, carried at arm's length by people in search of restoring a balance with the living by cohabiting with it and even stronger, by wishing to co-create again via a holistic management. This is the case of Xavier Dumont.
Xavier Dumont is an amateur beekeeper at the Rucher de Cantegril in Toulouse. He was faced with a significant loss of his colonies following the thaw. In February 2019, three of his colonies lost their lives because the bees were no longer numerous enough to warm up.
In addition to the fatal outbreaks mentioned above, a too mild climate during these periods is responsible for the proliferation of varroa mites in the hives. Varroa is a parasite that spreads through the brood (the pupae, larvae and eggs protected by the worker bees).
Normally, there is not supposed to be any egg laying during the winter period but because of global warming, the trend has been reversed and the hives are infested by these pests, decimating the swarms and forcing beekeepers to use more and more inputs (use of chemical products). The vicious circle is set in motion.

Hibernate the bees
Faced with this double observation, Xavier Dumont immediately thought of the varroa mite not as a cause but as a consequence of global warming.
"I was a beekeeper from the age of 20 to 30. Once I retired, I took over the hives. It has been 9 years now. I experienced the winters 40 years ago, which gave me the idea to do what I do today. I am a scientist at heart and curious. I always have a logbook where I write down everything about my colonies. Every year I would record honey harvests, diseases etc. And I noticed that there were colonies that were dying that would never have died forty years ago. I asked myself what had changed, and I quickly realized that it was the milder winters," he explains for La Relève and La Peste.
In a healthy ecological context, bees go into lethargy during the winter. Virtually immobile and huddled together, they release calories that keep them at a temperature of 32 to 36 degrees. This is how they survive.
"Bees are, individually, poikilothermic insects, (which do not regulate their temperature). But, in winter, grouping together to form the cluster, they become like a single homeothermic organism, maintaining an average temperature of 32 to 36° when there is brood, and 25° in theory when there is none, in the coldest part of winter. They transform glucose, coming from their honey reserves in winter, or by lipolysis, from their fat reserves, into calories and therefore heat.
By going out more during this period, which is nevertheless colder, they burn their fat outside... There is an imbalance and the bees succumb before they have time to be replaced. This is why Xavier Dumont decided to conduct an experiment.
"I thought back to my experience forty years ago, when I had an apiary. I went to observe them every day and sometimes they didn't come out for 3 weeks or even a month. So I thought I would artificially reproduce a similar climatic environment. I put them in my cellar, in fact my garage, in the dark so that they would not be incited to come out and would go into lethargy. The result exceeded my expectations," he smiles for La Relève and La Peste.
For 70 days, he placed four hives with different numbers of bees and queens of varying ages in a garage. The garage was in the dark. Every twelve days he let them out for a whole day so that they could defecate and avoid the risk of dysentery. The temperatures varied from 0° to 12°. The idea was to reproduce a climatic environment similar to that of forty years ago.
As the cycle resumed, the bees were discouraged from going outside because of the cold temperatures and therefore went into a state of lethargy to survive the season. The result: he found 100% survival of his colonies.
His findings are as follows:
* Queens did not lay eggs for 60 days.
* Radical drop in varroa mites.
* Weight loss of the bees between 2.1 kg and 6.1 kg over 70 days. This allowed them to resist all winter by being vigorous.
* Mortality rate of the bees between 105 and 350 per hive in 70 days against the totality of its apiary in 2019
* 60kg of honey harvested at the end of August on average per hive.
An appeal to all beekeepers
At first, his beekeeper neighbors were not convinced by the experience. But faced with this obvious success,
At first, his beekeeping neighbors were not convinced by the experiment. But faced with the obvious success, they quickly changed their minds.
"The first year I was called crazy. Some professionals told me that the problem with the bees was the varroa mite, which is a brood parasite. Most of the deaths are from pesticides and varroa mites. So I did my experiment and every time I had results, I sent them the report. When they saw the final results in the spring, they totally changed their minds. Others followed my idea directly, but as they did not have a cellar, I suggested other types of protocols which are explained in detail on my website. Those who tried it told me that their bees were doing very well and that it was more than expected," enthused Xavier Dumont to La Relève and La Peste.
The figures speak for themselves, from 100% loss, he went to 100% survival. For this reason, he has decided to launch an appeal to beekeepers to repeat this experience on a large scale next winter.
He would like to have enough participants so that the study can be taken seriously and be considered conclusive. Thus, those who wish to do so can go directly to his website: https://lerucherdecantegril.wordpress.com/ where all the steps and protocols are explained in detail. If beekeepers do not have a cellar, he proposes two alternatives to make the experiment feasible.
In the wild, bees fare better than their domestic counterparts. Some wild swarms live in walls or in tree trunks and never die. Unlike hives, which let the sunshine through more easily and thus heat up the wood more quickly, causing the bees to leave during cold spells, wild swarms are protected from this phenomenon. The environments the bees choose remain in darkness and take longer to warm up.
"It would take at least three or four days of bright sunlight for it to reach the colony. This gives them much less incentive to go outside. It's often said: bees are "the heat, the sun", so what I'm saying may seem counterintuitive, but that mantra doesn't hold true in winter. They work in cycles. In the spring, they need to have mild conditions for honey flows but in the winter, they need to be faced with cold to stay lethargic to preserve themselves. Wild bees are better off because they are not in hives and they often simply swarm," explains Xavier Dumont at La Relève and La Peste.
The mobilization of beekeepers is therefore vital for the survival of bees in hives.
Even beginner beekeepers are invited to participate in the experiment. Nearly 300 hives will already be subjected to the experiment. Ideally, Xavier Dumont would like to be able to test the experiment with 4,000 to 5,000 colonies, in order to be able to compare the benefits according to the age of the queen, but also the hives that are not treated with amitraz for example. This pesticide used to control varroa mites is also harmful to bees.
Once the confinement of bees on a large scale will have proved that harsh winters are necessary for their survival, it will be time to reproduce this experimentation not in garages but outside by fighting against global warming to keep the living intact and thus rethink our relationship with it in a holistic and benevolent vision. Because we must not forget that we are an integral part of the living and that without it, we are nothing.

Blue Mist Spirea (Caryopteris x clandonensis)
I'm looking forward to tomorrow, finding and bringing home some Blue Mist. A plant that bees and butterflies love.
One of those 'Angels Among Us' introduced me to this plant while I was looking for the last of Summer Roses.
It's going to be a Trek of Two Trains, and walking several miles to reach my destination, and then back home again-with the Blue Mist.
The total harvest of #RunnerBeans this year is going to be something like 30 kg.
Here is part of today's batch.
Among them, was a whopper which was over 35 cm in length.
Talking of whoppers, a huge #BumbleBee happened to fly past while I had my camera in my hand. Luckily, I managed to #photograph it but you don't get a sense of how big this beautiful specimen was. It was about the size of a golf ball!
