I've been playing the guitar for a while now. This usually involves you liking a song and then googling the guitar tab so you can play it. One (dark) day my Internet connection was down so I thought I'd play random notes. After a while the notes formed a song.
Vocals are by my brother Sam, and the song is called Brother:


The Equine LTS, has its foundation in the NASA LED research. The evolution within Light Emitting Diode (LED), has been exponential since 2002. The Equine LTS is using LED Chips, not the old fashioned light emitting diode bulbs, for a more stream lined look and 120 degrees light. The LED chips is mounted on a flexible strip, pre-wired with resistors and coated with a water resistant silicon top, to maintain durability and easy cleaning. The LED strips are powered by a 12V rechargeable battery.


Introducing the new Britax BFR1000 with CyclOne LED technology!
The Britax BFR1000 rotating LED beacon features unique CyclOne LED Technology with high reflectivity free-form rotating reflector and two rotation speeds and directions. Certified to SAE J845 Class 1, this beacon is truly powerful and comes with a three-year warranty.
Britax have created an all new LED beacon: designed from the ground up to create a true rotating beacon, but with all the advantages of using LED light output. The unique CyclOne technology is made up of a custom designed single source high output LED combined with a highly reflective free-form rotator—both of which work together to project a powerful warning signal over long distances.
The BFR1000 also features a tough polycarbonate amber lens with a smooth finish for increased dust resistance and low wind drag. The O-ring within the lens creates a seal that provides high dust, moisture and vibration resistance. This combined with the gel-filled base gives this beacon a rating of IP67.
The base is constructed from heavy duty die-cast alloy, which provides maximum durability and also highly efficient heat sinking for the LED system. The base comes with a rubber mounting gasket that allows for different mounting options whilst keeping the underside area of the beacon sealed at all times.
Two internal jumper selectors provide options of two rotation speeds and directions: clockwise or anti-clockwise rotation, and speeds of 120rpm or 180 rpm. The bolt base version also has an additional user selectable 30% dimming function for night use. Both the bolt base and magnetic base versions are multivoltage (10–30VDC). Certified to SAE J845 Class 1, this beacon is truly powerful and comes standard with a three-year warranty.

Camfil APC has introduced the Gold Series X-Flo (GSX), a powerful and cost-efficient system for collecting and containing the fumes generated by plasma cutting tables. The system is used in conjunction with a downdraft table to capture fumes at their source, reducing operator exposure to toxic fumes and helping shops meet OSHA permissible exposure limits (PELs).
GSX systems effectively process fumes while maintaining a low pressure drop. They are designed to pulse-clean more effectively to extend filter life, while minimizing compressed air usage and energy costs. The units are built modularly, providing maximum airflow and processing power for any given footprint. GSX systems can achieve efficiencies as high as MERV 15 using filter cartridges with HemiPleat® eXtreme nanofiber media.
The GSX exceeds OSHA mandates for indoor air quality and is tested to meet NFPA and ATEX standards.

RJ31X Jack with Cord
The Ultratech RJ31XSET includes an RJ jack and a connecting cord. An RJ jack is used to "release" the panel from the phone line so the telephone can be used. If the panel must sound an alarm, its built-in relay will seize the phone line so that the system can dial out. Buy the R31XSET here.
The Ultratech RJ31XSET with cord provides an RJ jack for an alarm system that uses a phone dialer. This is a very important component when setting up a security system for POTS (plain old telephone service) communication. The RJ jack allows the phone to be used when the panel is wired in.
In order for a POTS system to work effectively, it needs to be able to seize the phone line at any time in case of an emergency. The RJ enables the system to temporarily "give up" the phone line so that the phone can be used. However, if an alarm occurs while the phone is being used, the system will use a built-in relay to steal the phone line back so that it can properly dial out.

In hydrocarbon contaminated sites, it is common practice to collect hydrocarbon thickness measurements from monitoring wells. This data is later used in computer models to estimate the total hydrocarbon volume at these sites during various stages of remediation. The purpose of this effort is to estimate or evaluate the efficiency of the overall remediation process at a particular site. In most cases, the data obtained from this analysis show significant variations in total volume estimates over time. This may imply that the assumptions used in relating the monitoring well hydrocarbon thickness measurement data to the formation hydrocarbon volume may not be representative of the conditions at the site. In this paper we investigate the effect of groundwater table fluctuations in an unconfined aquifer, on the hydrocarbon measurements in a monitoring well using analytical methods. Our findings indicate that, under fluctuating groundwater table conditions, if the total volume estimates in the formation are based on monitoring well measurement made at one point in time, or if these estimates are based on a sequence of measurements made over a period of time which are than evaluated independently, the volume estimate results will be in significant error.

1 of 3 The cost of buying an electric appliance can vary greatly depending on its brand, model, and model year, as well as the type of electrical equipment used.
That’s because electric appliances, which are also called electrical equipment, typically include all of the electrical components that make up the appliance, including power, lighting, controls, and the like.
A common electrical appliance type is a typical home or small business electrical system, or HVAC.
There are also many other types of electric appliances that can be bought and sold, including appliances for homes, restaurants, hospitals, and schools.
The main thing to keep in mind is that the electrical appliances themselves have to be rated for proper serviceability, so if the manufacturer or retailer does not guarantee the electrical equipment will work properly for the customer, it could be a problem.
Here’s what you need to know about electric appliances: Types of electric equipment Electric appliances that are typically considered residential electric systems can be divided into two broad categories: home electric systems and small businesses electric systems.
Home electric systems are designed to provide electric service to your home and other rooms.
They are typically built in a home, and typically include the following components: A home electrical system consists of multiple electrical components (power, heating, cooling, and cooling equipment).
There are typically multiple types of home electric circuits that control different parts of your home, such as the air conditioner, refrigeration, or air conditioning.
For example, a refrigerator in a large home might have a large circuit that turns on when the temperature is low.
This is a common type of home electrical circuit, and it’s often called a power circuit.
A refrigerator in an industrial facility might have smaller circuit that runs when a temperature drops, and that’s a smaller type of power circuit, called an AC/DC circuit.
If you have two power circuits running in parallel, you have a parallel power system, called a DC/AC system.
A typical home electrical outlet has two electrical components: a breaker, and a connection to a wall socket.
The breaker is the main component that connects to the electrical outlet.
A wall socket is a device that connects the electrical socket to the wall.
In most cases, a wall outlet is connected to the same electrical outlet that’s being operated by the home electrical systems, which is typically a central or main outlet.
If the electrical system you have is not in a typical house, then you may be able to find other ways to get electricity from your home electrical network.
The power system used by a home electric system is the same that is connected from the electrical supply to the home.
If a wall breaker goes bad, then the power system that’s connected to that breaker may not be working correctly.
For most home electric outlets, you will need to replace the breaker.
You can usually find a home electrical supply company that will have a replacement available for your home.
A home electric circuit that is being operated and controlled by a wall-socket electrical outlet is called a load-out circuit.
You may need to connect a load of various types of components to a load terminal.
Some load-outs use electrical outlets to run various parts of the system, such that a circuit of four outlets can run multiple components of the home’s electrical system.
For more information on home electrical, see “Home Electric: Connecting Electrical Systems and Equipment” on our web site.
A household electrical system that is not a home-type electrical system may also be referred to as a small business or small home electric.
The name “small business” refers to the type or the size of the business, but this term is also used to describe an electrical appliance, or a household electrical supply system.
These small business electric systems typically consist of multiple small electrical circuits, including the breaker, to run a number of small components of a home’s electric system.
If there are two home electrical outlets running in series, you may need a power line to connect these outlets to the grid.
If two home-size outlets run parallel to each other, you can connect a power connection to both of them.
The same can be said for a household-sized electrical supply.
The home electrical grid is typically called the local electric distribution system (LEPS), which refers to both the distribution of electricity from the home to the entire state, and also to the distribution system for local telephone service, internet access, and phone service in rural areas.
The system is usually installed by a private utility or a state-regulated electric service provider, and usually includes both a home and a small-business electric supply.
If your home has a power supply, you are responsible for maintaining it.
For a home with a home power system installed by an electric utility, the system has to be switched on when electricity is needed to power a room or house, and must be turned off when electricity becomes unavailable.
If an electric service is not available, a power outage can occur. For small

The ceremony took place via a video link as part of the meeting of the Gazprom Board of Directors.
In the course of the event, supplies of process steam to the Amur Gas Processing Plant (GPP) started for the purposes of start-up and commissioning.
The GPP will become one of the world’s largest facilities in terms of gas processing (42 billion m3 per year).
Gas will be supplied to the GPP via the Power of Siberia gas pipeline.
The main purpose of the Svobodny TPP is to provide the Amur GPP with thermal energy (steam) and electricity.
Steam performs an important function across the GPP’s entire production chain: it is used as a heat carrier in heat exchangers and is required for both preheating feed gas and conducting the gas separation process.
The overall installed capacity of the TPP is 160 MW for power and 249 Gcal/h for heat.
Domestic equipment was widely used in the creation of the Svobodny TPP.
This includes the core equipment:
- 3 power steam boilers
- 2 steam turbine power units
- a single digital control and monitoring system
2 dry cooling towers, which are required for cooling the water used in the process cycle, were winterized so as to protect their assemblies and equipment during extreme cold temperatures (in the area of Svobodny, temperatures can drop below - 40 degrees Celsius).
A 220/110 kV switchgear and power transmission lines were built in order to transmit electricity from the Svobodny TPP to Russia’s Unified Energy System and further to the Amur GPP.

Primum non nocere. First, do no harm.
This phrase, espoused in the Hippocratic Oath, serves as the bedrock for the provision of medical care. Yet, for too many individuals and families who visit health care facilities, this tenet may not hold true. Roughly one in seven patients in low- and middle-income countries will develop an infection following admission to a facility. These infections not only have a significant impact on patient morbidity and mortality, but also lead to significant cost burdens for patients and the health system.
Safe water, sanitation, and hygiene (WASH) is recognized as a cornerstone for the provision of quality health care services and infection prevention and control. Yet clear gaps exist regarding WASH services and infrastructure in health care facilities. Globally, roughly 26% of health care facilities lack access to safe water services. An estimated 21% of health care facilities lack any type of sanitation service, and 16% lack any type of hand hygiene service. These gaps increase the potential for the spread of pathogenic organisms via direct patient-provider contact and contact with environmental surfaces. Without interrupting the transmission of bacteria, leading causes of maternal and neonatal death (e.g., sepsis), fecal-oral transmitted diseases (e.g., typhoid and diarrheal diseases), and the rise of multidrug-resistant bacteria will continue.
Fortunately, momentum for addressing gaps in WASH services in health care facilities (HCF) is growing. On May 25, 2019, the World Health Assembly unanimously approved a WASH in HCF resolution calling on member states to prioritize and commit to improving WASH services in HCF. National governments have committed to improvements related to building workforce capacity, developing standards, and allocating funds. Global researchers have generated and proposed actionable approaches to overcoming gaps, as exemplified in a research summary published by the Global Handwashing Partnership, focused on ‘clean hands for all.’ In parallel, leading multilateral institutions such as the World Health Organization have published strategies for implementing multimodal hand hygiene programs to stem the spread of infections. When combined with multifaceted infection prevention and control policies and practices, these programs have successfully reduced rates of hospital-acquired infections.
PATH and MSR Global Health are contributing to improved infection prevention and control activities in HCF by advancing an innovation called the MSR SafiStation™ Chlorine Generator. The device is an easy-to-use chlorine generator designed for low-resource settings. It uses salt, water, and electricity to produce a 1% chlorine solution for infection prevention and control and drinking water treatment. PATH is currently evaluating the effect of the device on environmental hygiene in labor wards in Kenya, as well as working to introduce and scale the device in Ghana and Uganda. In Kenya, SafiStation-generated chlorine will be used for drinking water treatment, treatment of handwashing solution, and surface and equipment disinfection. The hypothesis is that the introduction and use of the SafiStation and its chlorine will result in cleaner environments for patients—in particular, mothers and newborns—and ultimately reduce hospital-acquired infections. In Ghana and Uganda, the SafiStation will be positioned for integration and rollout in national HCF across the two countries.
In addition to WASH approaches, additional prevention strategies are often needed. For example, in communities with limited sanitation infrastructure that are vulnerable to typhoid, vaccinating children with typhoid conjugate vaccine (TCV) provides a crucial complementary approach to stemming the spread of typhoid through WASH measures. Vaccines against cholera, rotavirus, and other fecal-oral pathogens play similarly important roles. Additionally, in the case of infection, facilities should ensure availability and proper use of appropriate antibiotics and other treatment measures.
Infection can come from many angles. Comprehensive, multimodal strategies effectively address the numerous transmission routes of disease-causing pathogens. Approaches range from individual tools, such as ensuring each hospital ward has a handwashing station with soap and clean water or introducing a vaccine, to integrated, multilayered programs that intertwine leadership capacity building, disease surveillance, next-generation WASH technologies, and vaccines. Regardless of the approach, the goal remains the same: ensuring children and their families are protected through multiple interventions—including health care facilities equipped to provide safe, quality health care, adequate WASH, and equitable access to vaccines—in order to safeguard health for all.

Researchers from the University of Bonn demonstrated quantum entanglement between a stationary qubit and a photon with direct coupling to an optical fiber. The work represents a major step toward the realization of quantum networks and, from them, secure data transmission. Quantum networks necessitate stationary qubits be entangled with the communication channel, typically consisting of photons. A quantum state cannot be copied and transmitted in a classical sense. Photons, though difficult to store, are typically favored for transmission in quantum communication applications, both those that are in practice and those that are theoretical, due to their speed.

LEXINGTON, Ky. (Nov. 6, 2017) — Most people don't realize that the power to prevent many diseases is in their own hands.
By exercising – even a little – and quitting smoking, you greatly reduce your risk for diabetes, heart disease and even dementia. But perhaps the easiest way to tip the odds in your favor is to change your diet. If you're looking for a way to eat healthier, consider a plant-based diet.
It's a diet based on fruits, vegetables, whole grains and legumes. It excludes or minimizes meat, eggs and dairy products, as well as highly processed foods like bleached flour, refined sugar, and some oils.
Numerous studies have linked a plant-based diet to lower risks of diabetes, high blood pressure, and heart disease – as much as 30 percent, according to one Harvard study.
Don't know where to begin? Here are some guidelines:
Veggies: Any vegetable, especially leafy green or yellow vegetables with high water content.
Fruits: no limits here, but deeply colored berries are a plus.
Starches: this includes starchy vegetables like potatoes as well as whole grains like oats, rice or quinoa.
Beans and legumes: These are starchy, but generally have a higher protein content. Consider beans, lentils and dried peas.
Nuts and seeds: use sparingly to avoid weight gain.
You can adjust slowly to a plant-based diet. Adopt the popular "Meatless Mondays" trend in your home and add Tuesday, Wednesday, etc. as you go. Or experiment by adjusting your favorite recipes to be plant-based: make your chili all beans, or prepare a stir-fry with tofu or edamame instead of chicken.
If you want some ideas, come to UK HealthCare on Saturday, Nov. 18 for "Feeding Your Heart and Soul" featuring best-selling cookbook author Jane Esselstyn. Esselstyn, who has spent most of her life advocating for a plant-based, meatless, whole food diet, will demonstrate recipes from The Prevent and Reverse Heart Disease Cookbook, which she co-authored with her mother, Ann. You'll also get the opportunity to taste some of her dishes and see for yourself that a plant-based diet can be healthy and delicious.
The morning will begin at 8 a.m. with an optional free yoga session. Esselstyn will take the stage for a brief lecture at 9 a.m., followed by a cooking demonstration at 10 a.m. and tastings at 11 a.m.
The registration fee for "Feeding Your Heart and Soul" is $15 and includes a free copy of The Prevent and Reverse Heart Disease Cookbook and tastings.

The Avery Research Center at the College of Charleston has acquired an 1860 first edition of one the pre-eminent slave narratives, Running a Thousand Miles for Freedom. The acquisition was made possible through a generous donation by the Honorable Senator Herbert U. Fielding and the Honorable Judge Bernard R. Fielding of Charleston, the Alpha Phi Alpha Fraternity, and the College of Charleston Friends of the Library.
“By acquiring this rare book, we are able to tell a more comprehensive story about a courageous couple and their progeny here in Charleston. The Crafts’ narrative is a fitting addition to our collections because it demonstrates the visceral ways the International Slave Trade impacted the lives of enslaved people told in their own words. It also provides us a missing link in our efforts to document and contextualize their experiences and that of their descendants—namely the DeCosta clan– here in Charleston.” said Dr. Patricia Williams-Lessane, Executive Director of the Avery Research Center.
Published in 1860, Running a Thousand Miles for Freedom is the dramatic account of William and Ellen Craft’s escape from Macon, Ga. through Savannah, Charleston, Wilmington, Washington, DC, Baltimore and on to Philadelphia. The account describes how the light-skinned Ellen Craft dressed as a man and pretended to be a wealthy, white invalid seeking treatment in Philadelphia, while accompanied by “his” slave, William (i.e. her husband).
Slave narratives like Running a Thousand Miles for Freedom are one of the most valuable sources available for providing first-hand experiences of slaves in the American South. These autobiographical narratives also comprise one of the most extensive and influential traditions in African American literature and culture. Slave narratives have gained prominence in colleges and universities to provoke reflection, discussion and debate among students and scholars on the questions of race, social justice and the meaning of freedom.
“Acquisitions like this position Avery and the College as one of the nation’s intellectual and cultural leaders in documenting and preserving African American history and culture,” says College of Charleston Provost George Hynd.
Founded in 1865 as the Avery Normal Institute, this community hub provided education and advocacy for the growing Charleston African-American community and trained blacks for professional careers and leadership roles. While the Institute closed its doors in 1954, its graduates preserved the legacy of their alma mater by establishing the Avery Institute of Afro-American History and Culture in 1979.
The modern day rebirth of Avery began in 1985 with the establishment of the Avery Research Center for African American History and Culture at the College of Charleston. For the last twenty-five years, Avery has collected art and archival materials that document the history, traditions and legacies of African Americans and their influence on American society and culture, as well as their place within the American narrative. With a repository of primary and secondary source material of nearly 4,000 holdings, the Center supports scholarship, research and presentations by scholars, students, and public historians.
Nearly 3000 patrons visit Avery annually with teachers and students from across the U.S. and abroad arriving regularly for tours, workshops and summer history camps. Additionally, partnerships with Charleston Public Schools, Berkeley Public Schools, the City of Charleston’s MOJA Arts Festival and other community groups extend Avery’s reach into local communities.
Today, the Avery Research Center for African American History and Culture is listed on the National Register of Historic Sites. The only research center of its kind in the Southeastern United States, it continues to advance the goals and mission of the College of Charleston while sustaining the remarkable legacy of the original Avery Normal Institute as a vital community center and essential source of information pertaining to the African-American experience.

The disproportionate impact of COVID-19 on racially marginalized communities has again raised the issue of what justice in healthcare looks like. Indeed, it is impossible to analyze the meaning of the word justice in the medical context without first discussing the central role of racism in the American scientific and healthcare systems. In summary, we argue that physicians and scientists were the architects and imagination of the racial taxonomy and oppressive machinations upon which this country was founded. This oppressive racial taxonomy reinforced and outlined the myth of biological superiority, which laid the foundation for the political, economic, and systemic power of Whiteness. Therefore, in order to achieve universal racial justice, the nation must first address science and medicine’s historical role in scaffolding the structure of racism we bear witness of today. To achieve this objective, one of the first steps, we believe, is for there to be health reparations. More specifically, health reparations should be a central part of establishing racial justice in the United States and not relegated to a secondary status. While other scholars have focused on ways to alleviate healthcare inequities, few have addressed the need for health reparations and the forms they might take. This piece offers the ethical grounds for health reparations and various justice-focused solutions.


Frugal Abundance in an Age of Limits
Our planet was once relatively empty of humans; today it is full to overflowing, with more people consuming more resources. We are used to hearing that if everyone lived in the same way as North Americans or Australians, we would need four or five planet Earths to sustain us.
This sort of analysis is known as the “ecological footprint” and it shows that even the so-called “green” western European nations, with their more progressive approaches to renewable energy, energy efficiency and public transport, would require more than three planets.
In the face of this reality, what does genuine economic progress look like? The orthodox answer is to insist blindly that a bigger economy is always better; that growth is the solution to the problems growth itself is causing. But this idea is increasingly strained by the knowledge that, on a finite planet, the economy can’t grow forever.
Like a snake eating its own tail, our growth-oriented civilisation suffers from the delusion that there are no environmental limits to growth. But rethinking growth in an age of limits cannot be avoided. The only question is whether it will be by design or disaster.
We all want to live well and flourish within the means of our planet. When we delve seriously into this question, however, it becomes clear that almost all environmental literature grossly underestimates what is needed for our civilisation to become sustainable.
Only the brave should read on.
The ‘ecological footprint’ analysis
In order to explore the question of what “one planet living” would look like, let us turn to what is arguably the world’s most prominent metric for environmental accounting – the ecological footprint analysis. This was developed by Mathis Wackernagel and William Rees, then at the University of British Columbia, and is now institutionalised by the scientific body, The Global Footprint Network, of which Wackernagel is president.
This method of environmental accounting attempts to measure the amount of productive land and water a given population has available to it, and then evaluates the demands that population makes upon those ecosystems. A sustainable society is one that operates within the carrying capacity of its dependent ecosystems.
While this form of accounting is not without its critics – it is certainly not an exact science – the worrying thing is that many of its critics actually claim that it underestimates humanity’s environmental impact. Even Wackernagel, the concept’s co-originator, is convinced the numbers are underestimates.
According to the most recent data from the Global Footprint Network, humanity as a whole is currently in ecological overshoot, demanding one and a half planets’ worth of Earth’s biocapacity. As the global population continues its trend toward 11 billion people, and while the growth fetish continues to shape the global economy, the extent of overshoot is only going to increase.
The footprint of an ecovillage
The basic contours of environmental degradation are relatively well known. What is far less widely known, however, is that even the world’s most successful and long-lasting ecovillages—which can be broadly understood as “intentional communities” that form with the explicit aim of living more lightly on the planet—have yet to attain a “fair share” ecological footprint.
Take, for example, what is probably the most famous ecovillage in the world: the Findhorn Ecovillage in Scotland. Among other things, the Findhorn community has adopted an almost exclusively vegetarian diet, produces renewable energy and makes many of their houses out of mud or reclaimed materials.
But when an ecological footprint analysis was undertaken, it was discovered that even the committed efforts of this ecovillage still left the Findhorn community consuming resources and emitting waste far in excess of what could be sustained if everyone lived in this way. (Part of the problem is that the community tends to fly as often as the ordinary Westerner, increasing their otherwise small footprints.)
Put otherwise, and more precisely, if the whole world came to look like one of our most successful ecovillages, we would still need the biocapacity of one and a half planet Earths. Dwell on that for a moment.
I do not share this conclusion to provoke despair, although I admit that it conveys the magnitude of our ecological predicament with disarming clarity. Nor do I share this to criticise the noble and necessary efforts of the ecovillage movement, which clearly is doing far more than most to push the frontiers of environmental practice.
Rather, I share this in the hope of shaking the environmental movement, and the broader public, awake. In a full world of seven billion people and counting, a “fair share” ecological footprint means reducing our impacts to a small fraction of what they are today. Such fundamental change to our ways of living is incompatible with a growth-oriented civilisation. The very lifestyles that were once considered the definition of success are now proving to be our greatest failure. Attempting to universalise affluence would be catastrophic. Even the ‘ecovillage’ way of life needs to be challenged.
I am aware that some people may find this this position too “radical” to digest, but I would argue that this position is merely shaped by an honest review of the evidence. With our eyes open, let us begin by acknowledging that tinkering around the edges of consumer capitalism is utterly inadequate.
We need an alternative.
What would ‘one planet’ living look like?
Even after five or six decades of the modern environmental movement it seems we still do not have an example of how to thrive within the sustainable carrying capacity of the planet. Nevertheless, one thing is clear: given the extent of ecological overshoot—and bearing in mind that the poorest nations still need some room to develop their economies and allow the poorest billions to attain a dignified level of existence—the transition to a sustainable way of life will require the richest nations to radically downscale their resource and energy demands.
This realisation has given rise to calls for economic “degrowth”. To be distinguished from recession, degrowth means a phase of planned and equitable economic contraction in the richest nations, eventually reaching a steady state that operates within Earth’s biophysical limits.
When one first hears calls for degrowth, it is easy to think that this new economic vision must be about hardship and deprivation; that it means going back to the stone age, resigning ourselves to a stagnant culture, or being anti-progress. Not so.
Degrowth would liberate us from the burden of pursuing material excess. We simply don’t need so much stuff; certainly not if it comes at the cost of planetary health, social justice, and personal well-being. Consumerism is a gross failure of imagination, a debilitating addiction that degrades nature and is questionable even in its ability to satisfy the universal human craving for meaning.
Degrowth, by contrast, would involve embracing what has been termed the “simpler way” – producing and consuming less.
This would be a way of life based on modest material and energy needs but nevertheless rich in other dimensions – a life of frugal abundance. It is about creating an economy based on sufficiency, knowing how much is enough to live well, and discovering that enough is plenty.
The lifestyle implications of degrowth and sufficiency are far more radical than the “light green” forms of sustainable consumption that are widely discussed today. Turning off the lights, taking shorter showers, and recycling are all necessary parts of what sustainability will require of us, but these measures are far from enough.
But this does not mean we must live a life of painful sacrifice. Most of our basic needs can be met in quite simple and low-impact ways, while maintaining a high quality of life.
What would life be like in a degrowth society?
In a degrowth society we would aspire to localise our economies as far, and as appropriately, as possible. This would assist with reducing carbon-intensive global trade, while also building resilience in the face of an uncertain and turbulent future. We must ride our bikes more and fly less.
Through forms of direct or participatory democracy we would organise our economies to ensure that everyone’s basic needs are met, and then redirect our energies away from economic expansion. This would be a relatively low-energy mode of living that ran primarily on renewable energy systems.
Renewable energy cannot sustain an energy-intensive global society of high-end consumers. A degrowth society embraces the necessity of “energy descent”, turning our energy crises into an opportunity for civilisational renewal.
We would tend to reduce our working hours in the formal economy in exchange for more home-production and leisure. We would have less income, but more freedom. Thus, in our simplicity, we would be rich.
Wherever possible, we would grow our own organic food, water our gardens from water tanks, and turn our neighbourhoods into edible landscapes as the Cubans have done in Havana. As my friend Adam Grubb so delightfully declares, we should “eat the suburbs”, while supplementing urban agriculture with food from local farmers’ markets.
More broadly, we must turn our homes and communities into places of sustainable production, not unsustainable consumption. In doing so, we must challenge ourselves to journey beyond the ecovillage movement and explore an even deeper green shade of sustainability.
We do not need to purchase so many new clothes. Let us mend or exchange the clothes we have, buy second-hand, or make our own. In a degrowth society, the fashion and marketing industries would quickly wither away. A new aesthetic of sufficiency would develop, where we creatively re-use and refashion the vast existing stock of clothing and materials, and explore less impactful ways of producing new clothes.
We would become radical recyclers and do-it-yourself experts. This would partly be driven by the fact that we would simply be living in an era of relative scarcity, with reduced discretionary income.
But human beings find creative projects fulfilling, and the challenge of building the new world within the shell of the old promises to be immensely meaningful, even if it will also entail times of trial. The apparent scarcity of goods can also be greatly reduced by scaling up the sharing economy, which would also enrich our communities.
One day, we might even live in cob houses that we build ourselves, but over the next few critical decades the fact is that most of us will be living within the poorly designed urban infrastructure that already exists. We are hardly going to knock it all down and start again. Instead, we must ‘retrofit the suburbs’, as leading permaculturalist David Holmgren argues. This would involve doing everything we can to make our homes more energy-efficient, more productive, and probably more densely inhabited.
This is not the eco-future that we are shown in glossy design magazines featuring million-dollar “green homes” that are prohibitively expensive. Degrowth offers a more humble – and I would say more realistic – vision of a sustainable future.
In short, degrowth means living lives of frugality, moderation and material sufficiency – but lives that are rich in their non-materialistic dimensions. Unpopular though it is to say, we must also have fewer children, or else our species will grow itself into a catastrophe.
At this point, mainstream economists will accuse degrowth advocates of misunderstanding the potential of technology, markets, and efficiency gains to “decouple” economic growth from environmental impact. But there is no misunderstanding here. Everyone knows that we could produce and consume more efficiently than we do today. The problem is that efficiency without sufficiency is lost.
Despite decades of extraordinary technological advancement and huge efficiency improvements, the energy and resource demands of the global economy are still increasing. This is because within a growth-oriented economy, efficiency gains tend to be reinvested in more consumption and more growth, rather than in reducing impact.
This is the defining, critical flaw in growth economics: the false assumption that all economies across the globe can continue growing while radically reducing environmental impact to a sustainable level. The extent of decoupling required is simply too great. As we try unsuccessfully to “green” capitalism, we see the face of Gaia vanishing.
Making the change
A degrowth transition to a steady-state economy could happen in a variety of ways. But the nature of this alternative vision suggests that the changes will need to be driven from the “bottom up”, rather than imposed from the “top down”.
What I have written above highlights a few of the personal and household aspects of a degrowth society based on sufficiency (for much more detail, see here and here). Meanwhile, the ‘transition towns’ movement shows how whole communities can engage with the idea.
But it is critical to acknowledge the social and structural constraints that currently make it much more difficult than it needs to be to adopt a lifestyle of sustainable consumption. For example, it is hard to drive less in the absence of safe bike lanes and good public transport; it is hard to find a work-life balance if access to basic housing burdens us with excessive debt; and it is hard to re-imagine the good life if we are constantly bombarded with advertisements insisting that “nice stuff” is the key to happiness.
Actions at the personal and household levels will never be enough, on their own, to achieve a degrowth economy. We need to create new, post-capitalist structures and systems that promote, rather than inhibit, the simpler way of life. These wider changes will never emerge, however, until we have a culture that demands them. So first and foremost, the revolution that is needed is a revolution in consciousness.
I do not present these ideas under the illusion that they will be readily accepted. The ideology of growth clearly has a firm grip on our society and beyond. Rather, I hold up degrowth up as the most coherent framework for understanding the global predicament and signifying the only desirable way out of it.
The alternative is to consume ourselves to death under the false banner of “green growth”, which would not be smart economics. Can the descent from consumerism and growth be prosperous? Can we turn our overlapping crises into opportunities? These are the defining questions of our times.
We are at the crossroads, and are in the process of choosing our fate.


Founded in VI c AD by the head of the 13 Assyrian Fathers – St. Ioane Zedazneli, Zedazeni monastery is located north-east of Mtskheta, on the slope of a hill covered with dense virgin forest. The tradition clames that St. John deliberately choose this place, where the heathen idol had once stood and did not abandon a small cave – modest place of his hermitry even after his disciple Tateh built a “real” monastery in close proximity of the cave. According to the original manuscript narrating the life and deeds of the saint father, after his death he was buried in the cave, as was his last will. Shortly afterwards a small church was built over St. John’s grave, later incorporated into a larger church of St. John the Baptist, constructed in the end of VIII c. under the patronage of Patriarch Clementios. Up to now the church is the central building of the monastery. This three nave basilica with two pairs of roof-bearing columnsis built of mixed material – rubble stone, gallstone and brick. Eastern section of the northern nave incorporates the remains of the earlier, neatly hewn stonework structure with horseshoe shape arches. Here next to the northern wall, St. John Zedazneli’s grave is arranged. The church has got a rather peculiar rectangular sanctuary, while the conchs are arranged over the tromps constructed in the corners. Quite possibly the building initially had an opening from the west, most probably – an arch, imitating the church of Saint Grave in Jerusalem. A well is arranged in the main temple, in western section of its northern nave, where the spring, created by the force of St. John’s blessing and prayer is still pouring through. Central nave of the church strongly different from the other two. Is is higher, better illuminated and treated as if it were a separate hall, while the darkened south nave with a square room in its eastern end gives the impression of some kind of internal porch. The survived fragments of Zedazeni wall painting seemingly are of later times – most likely XVII c. A stone iconostasis adorned with rising ornamentation donated to the monastery by the Princes of Kakheti in XI c had once been standing here. Its survived slabs were taken to the Georgian state museum of art and are exhibited in the permanent exposition. Exterior of the basilica is rather plain and simple, almost ill-featured with only two slabs ornamented with crosses. Originally the basilica had only one – southern entrance that is overlapped by the neatly hewn stonework arched porch of IX – X cc with XVIII c bell-tower arranged on its top apparently added in times of Patriarch Domenti. The defensive wall and hermit sell remains are of the same period. Western door was arranged in XIX c. In 90-ies of the last century the monastery, abandoned for long time was brought back to life.

Parashat Hukat (Numbers 19:1 – 22:1)
“Anyone who looks at four things, it would have been better if they had not come into the world,” the Mishna declares in a furious mood in Hagigah 2:1: “what is above, what is below, what is before and what is after.” If you’re anything like my children, the moment that someone tells you not to think about something, not to bother investigating it, that it is just not your business – that is the moment that piques your urgent curiosity to delve in exactly there. Indeed, for the rabbis of the Talmud, who shared this human drive, this Mishna becomes the jumping off point for their earnest explorations of what might reside above, below, before and after.
Rashi seems to take a strategy similar to this Mishna with the beginning of parashat hukat, which introduces the detailed procedure for how to prepare a purifying elixir from the ashes of a red heifer. The elixir mysteriously makes those who handle it ritually impure while purifying those who receive it. Torah introduces the passage with zot hukat hatorah asher tzivah YHVH – this is the law of Torah that God commanded. Torah’s laws can be categorized in many ways; here the relevant division is hukim vs. mishpatim, that is, laws that have no external logical explanation (hukim) and laws that make sense for safety and kindness in human governance (mishpatim).
Rashi writes about our verse:
This is the law of Torah, because the Adversary and the nations of the world will hold Israel to account, asking “What is this commandment and what is the reason for it?” Therefore it is called hukah, meaning, it is a decree before Me and you do not have permission leharher ahareha – to ponder it/think about it/raise doubts about it.
Rashi is referencing sources in midrash (BT Yoma 67b and Tanhuma Hukat 7) that link this mitzvah to others that are also described as hukah – among them the prohibitions against mixing wool and linen in a garment and eating pork; and the process of sending the scapegoat out into the wilderness bearing the sins of the people on Yom Kippur. In his commentary on the Talmudic passage, Rashi articulates his concern:
You may not think about them – lest you say they are acts of tohu [of the chaos that pre-exists creation] – What atonement can there be in sending this thing out, and what could there possibly be in the cliff to help you?
By using the word tohu, which appears in the second verse of Torah to describe the state of being before creation, Rashi links pondering the red heifer’s ashes with the Mishna in Hagigah’s contemplation of what exists beyond the boundaries of known space/time. In Rashi’s formulation, to ask how or why this ritual works is to gaze into that abyss.
But the other thing we know from Rashi’s commentary (and from the millennia-old sources he is citing) is that this is one of the passages in Torah that we’re likely to get asked about. It’s been happening for thousands of years, and it is still happening today.
Last week, while I was waiting in line for lunch, an evangelical Christian friend approached me with curiosity, respect, and excitement to ask what I thought of the project she’d recently learned about to recreate the vessels of the Temple (including of course the ashes of the red heifer of our very verse). She was surprised that I was not yearning for a literal restoration of the Temple, and sat me down to ask about the mechanics of atonement in a non-sacrificial Judaism and the authority of Torah in the evolutionary Judaism I was describing – recognizing that our living practices will always be changing even as they remain linked to our origins (which makes space to literally pray for a metaphorical yearning). This conversation, fueled by mutual respect and curiosity, felt far from the abyss Rashi feared, but rather essential to the kind of learning that builds participatory democracy – actually understanding each other’s worldviews.
But it didn’t have to go that way. Rabbi Levi Yizhak of Berdichev (18th c. Poland) suggests that the Adversary might be asking about the red heifer to trouble Israel by raising the notion that this mitzvah’s purpose is to effect atonement for the transgression of worshipping the golden calf. With an intent to harm (rather than to learn), this inquiry is meant to raise the idea that there is some fundamental flaw in the relationship between God and Israel that must be repaired. The kind of contemplation Rabbi Levi Yitzhak would have us avoid by saying “it’s a decree don’t ask about it” is a questioning of our fundamental worthiness and connection.
Deep self-doubt can emerge just as easily from inner dialogue as from an external questioner. Rabbi Hayim Arye Leib (19th c. Russia) notices a doubling in Rashi’s comment “what is the commandment/what is the reason for it” and “it is a decree before Me/you do not have permission to ponder it.” He reads the doubling as two moments of inner doubt, one before doing a mitzvah and one after. Before, a person asks “What value and importance does this have? Might there be something more important to do?” and might thereby abandon the mitzvah that is in front of them. If they’ve done it even through the doubt, they might then ask afterwards, “What good does this mitzvah do? It must be one of the great ones,” and thereby stoke their own ego. Avoiding asking these questions would allow a person to simply do mitzvot without the self-doubt before or the self-aggrandizement afterward.
As they interpret Rashi’s proposed limit on discourse, these Hasidic rabbis have a laudable goal: allow us as Jews to seek to walk a path of holiness in the world without questioning our fundamental worthiness or puffing ourselves up with pride.
But in that quest we must not lose our fundamental curiosity and delight in exploring the mysteries we might never understand.
Talmud (Yoma 14a) suggests that the mystery inherent in contemplating the paradoxical action of the red heifer’s ashes goes back to ancient times, quoting King Solomon (Kohelet 7:23): “I thought I could fathom it, but it eludes me.” The next verse in that passage continues rhetorically: “The secret of what happens is elusive and deep, deep down; who can discover it?” But there is a long rabbinic tradition of reading rhetorical questions as invitations: Right – who can discover it? Keep seeking, keep contemplating, keep asking, with humility, confidence, desire and delight.
