WWF Finland has calculated that Wednesday April 11th is Earth Overshoot Day for the Finns – the point in each calendar year when the consumption of natural resources exceeds the earth’s ability to replace those resources for the current year.
Consumption of natural resources is well above the world average in Finland. If the entire population of the planet consumed natural resources at the same rate as the residents of Finland, we would need 3.6 earths to maintain a sustainable lifestyle.
In Finland, high levels of natural resources are consumed in generating energy, in transport and in food production.
Globally, Earth Overshoot Day this year will fall in early August.
May 8, 2018 at 9:10 am #52485rideforeverParticipantThere are a number of illusions here :
- That humans can do anything different – they just don’t get the message of so many failures, insensitive and dumb
- That life is for you to do something to …. rather than you are designed to work in co-operation with life for your own benefit
- That matter is what you are looking for
Understand this and seeing the endless frenetic activity of people wanting to save the planet, one realises that mankind is not close to any solution.
May 28, 2018 at 4:04 pm #52538c_howdyParticipantA circular economy is a regenerative system in which resource input and waste, emission, and energy leakage are minimised by slowing, closing, and narrowing energy and material loops. This can be achieved through long-lasting design, maintenance, repair, reuse, remanufacturing, refurbishing, and closed recycling loops. This is in contrast to a linear economy which is a ‘take, make, dispose’ model of production.

It’s too simplistic, but anyway in the right direction.

Old economics is based on false ‘laws of physics’ – new economics can save us
Things are not going well in the world’s richest economies. Most OECD countries are facing their highest levels of income inequality in 30 years, while generating ecological footprints of a size that would require four, five or six planet Earths if every country were to follow suit. These economies have, in essence, become divisive and degenerative by default. Mainstream economic theory long promised that the solution starts with growth – but why does that theory seem so ill-equipped to deal with the social and ecological fallout of its own prescriptions? The answer can be traced back to a severe case of physics envy.
In the 1870s, a handful of aspiring economists hoped to make economics a science as reputable as physics. Awed by Newton’s insights on the physical laws of motion – laws that so elegantly describe the trajectory of falling apples and orbiting moons – they sought to create an economic theory that matched his legacy. And so pioneering economists such as William Stanley Jevons and Léon Walras drew their diagrams in clear imitation of Newton’s style and, inspired by the way that gravity pulls a falling object to rest, wrote enthusiastically of the role played by market forces and mechanisms in pulling an economy into equilibrium.
Their mechanical metaphor sounds authoritative, but it was ill-chosen from the start – a fact that has been widely acknowledged since the astonishing fragility and contagion of global financial markets was exposed by the 2008 crash.
The most pernicious legacy of this fake physics has been to entice generations of economists into a misguided search for economic laws of motion that dictate the path of development. People and money are not as obedient as gravity, so no such laws exist. Yet their false discoveries have been used to justify growth-first policymaking.
In 1955, the economist Simon Kuznets thought he had found such a law of motion, one that determined the path of income inequality in a growing economy. The scant data that he could gather together seemed to suggest that, as a nation’s GDP grows, inequality first rises, then levels off, and ultimately starts to fall. Despite Kuznets’ explicit warnings that his work was 5% empirical, 95% speculation and “some of it possibly tainted by wishful thinking”, his findings were soon touted as an economic law of motion, immortalized as “the Kuznets Curve”– resembling an upside-down U on the page – and has been taught to every economics student for the past half century.
As for the curve’s message? When it comes to inequality, it has to get worse before it can get better, and more growth will make it better. And so the Kuznets Curve became a perfect justification for trickle-down economics and for enduring austerity today in the pursuit of making everyone better off some day.
Forty years later, in the 1990s, economists Gene Grossman and Alan Krueger thought they too had found an economic law of motion, this time about pollution. And it appeared to follow the very same trajectory as Kuznets’ curve on inequality: first rising then falling as the economy grows. Despite the familiar caveats that the data were incomplete, and available for local air and water pollutants only, their findings were quickly labeled the “Environmental Kuznets Curve”. And the message? When it comes to pollution, it has to get worse before it can get better and – guess what – more growth will make it better. Like a well-trained child, growth will apparently clean up after itself.
Except it doesn’t. If we have learned one thing from the emergent crises of recent decades – from the tipping points of climate change and the rise of the 1% to the near-collapse of financial markets – it is that it’s time for economics to ditch the fake physics. Thanks to more and better data, it has become clear that such economic laws of motion simply don’t exist. Far from being a necessary phase of development, extreme inequality and environmental degradation are the result of policy choices, and these choices can be changed. In the place of laws to be obeyed, there are design decisions to be made.
So if the economy is not best thought of as a mechanism that returns to equilibrium and follows fixed laws of motion, how should we think of it? Like the living world: it’s complex, dynamic and ever-evolving. And for economists, that means it’s time for a metaphorical career change: from engineer to gardener. Let’s take off the hard hat and give up on reaching for the economy’s control levers because they simply don’t exist. Instead, put on some gardening gloves, pick up a pair of secateurs, and start to steward the economic garden. And if you think that sounds laissez faire, then you’ve never done a hard day’s work in the garden: it calls for getting stuck in, digging, pruning, weeding and watering the plants as they grow and mature.
How can economic gardeners help to create a thriving economy, one that is inclusive and sustainable and will help to achieve the sustainable development goals? By following two core principles: make it regenerative and distributive by design.
Regenerative economic design ensures that instead of using up Earth’s resources, we use them again and again and again. We learn to work with, not against, the cyclical processes of life, including those for carbon, water and nutrients. Thanks to innovations in the circular economy and cradle-to-cradle design we can start turning last century’s degenerative economy into this century’s regenerative one.
Distributive economic design, in turn, ensures that value created is spread far more equitably among those who helped to generate it. Think employee-owned companies – such as the John Lewis Partnership and Unipart – that reward committed employees rather than short-term shareholders. Think community-owned renewable-energy systems that generate electricity along with income for community purpose. Think creative commons licensing that enables valuable innovations, like those of the Open Building Institute, to be shared, improved and used without end. Thanks to the rise of digital networks, there’s more opportunity than ever to turn last century’s divisive economy into this century’s distributive one.
So how can economic policymakers be more like gardeners in their approach? They should think of policy as an adapting portfolio of experiments, says Eric Beinhocker, a leading thinker in the field of evolutionary economics. We should mimic nature’s process of natural selection, which can be summed up as diversify-select-amplify: set up small-scale policy experiments to test out a variety of interventions, put a stop to the ones that don’t work and scale-up those that do. Nobel-prize-winning political scientist Elinor Ostrom agreed. “We have never had to deal with problems of the scale facing today’s globally interconnected society,” she wrote. “No one knows for sure what will work, so it is important to build a system that can evolve and adapt rapidly.”
Realising that the economy is ever-evolving is an empowering insight. If complex systems evolve through their innovations and deviations, then this gives added importance to novel initiatives – from complementary currencies to open-source design – that are at the leading edge of new economic design.
Better still, every one of us can have a hand in shaping the economy’s evolution. Not just in how we shop, eat and travel, but in how we volunteer, invest and protest. In how we set up new businesses, save for our pensions, license our inventions, and power our homes. Who knows, we could just turn out to be butterflies that stir up powerful winds of change.

- The material universe continuously degenerates through entropy, and this process can only be adjusted by The Light which comes from outside of this universe.
- The purpose of human life is as individuated consciousness of The Light, who must actualize their souls through struggle in life. Therefore they must be allowed to be free and area actually always under the laws of God and no others.
- Economists can emulate Nature simply by doing nothing. Then Nature will do everything already. However this will also not work because mater cannot prevent degeneration due to entropy.
- In common with most political opinions, the real material causes of the destruction of human culture are not explored as to do so is dangerous. Banking, Israel and so on. Question too much and you will be out of a job or life. Only meaningless opinions that do not threaten are permitted in the culture.
- The many will always be fully incapable of finding the hidden key inside.
- There are no problems in human life, there are just challenges that existence wishes you to be brave enough to confront, rather than wise-acre.
- A sage realises that people are like straw dogs .
- Our first job is to actualize ourselves, if you are able to do so, then you have enough competence to consider the lives of others, otherwise not.
May 29, 2018 at 7:10 pm #52545c_howdyParticipantHow greener grids can stay lit
May 24, 2018 by Holly Ober, University of California – Riverside
https://techxplore.com/news/2018-05-greener-grids-lit.html
Californians love renewable energy. In fact, California just became the first state to require solar panels on all new homes.
But the new requirement creates questions—How will the new law complicate the electricity market? What strains will it place on existing distribution networks?
As California scrambles to meet a 2030 deadline to receive 50 percent of its electricity from renewable sources, the state needs to find ways to track, measure, and value electricity consumption and production that account for the variability of electricity that comes from decentralized sources, such as solar, wind, and batteries. Without careful management, these sources, known as distributed energy resources, or DERs, have the potential to cause unreliable power delivery, or even outages, and lead utility companies to overcharge customers.
A new paper by electrical engineers in the Marlan and Rosemary Bourns College of Engineering at the University of California, Riverside, offers a way to account for uncertainties introduced by both the electricity market and DERs so utility companies can balance the distribution grid and find the fairest customer rates.
One way managers of the electricity market ensure equitable distribution of power is by offering incentives for customers to reduce, or defer, power consumption during peak hours. Customers can choose to use less electricity or shift their use to a distributed source, such as rooftop solar panels or batteries. Customers can also make more electricity available during peak loads by selling to the utility excess electricity generated by their rooftop solar panels. Consumers can thus exert a strong influence on the wider electricity grid and market.
The problem, according to the researchers, is that the organizations overseeing the grid as a whole, known as independent system operators, or ISOs, do not dispatch, and often can’t see, the location of network DERs. They only see transmission lines and resources connected to them, such as collective demand at the substations and power plants. They determine market conditions based on the big picture without knowing details that might have important consequences in the power grid.
“ISOs see the electricity up to the substation that feeds it into a consumer network but are blind to what happens among the thousands or millions of customers after that point,” explained Ashkan Sadeghi-Mobarakeh, a UC Riverside doctoral student in electrical and computer engineering and first author of the paper. “The demand of each customer at each location has a different local impact on the distribution network.”
California ISO, or CAISO, has introduced a new index to better manage flexible and responsive loads according to the market conditions. But the index suggests deployment of flexible loads only according to market conditions, meaning CAISO’s index doesn’t consider that market participation of DERs located in distribution networks may push a network’s limits.
If CAISO or the utility determine times to deploy or defer electrical loads without accounting for variable on-site renewable resources and distribution network conditions, they risk overloading the network and causing outages. Contrary to common sense, reducing electricity delivery to distribution feeders at peak load could lead to higher costs and decrease grid stability.
The UC Riverside paper considers not only the market conditions, but also the impact flexible resources have on distribution network constraints.
Sadeghi-Mobarakeh used novel algorithms to model cost and electrical loads in different market scenarios and tested them on a standard distribution network. He used his algorithm to compare the cost and stress on the distribution network to what would be predicted by the conventional model. He found that if the utility company had bid according to his model, they could have delivered power to consumers at considerably lower cost on many days, with less risk to the network.
The researchers propose two new indexes to help utilities look beyond market conditions and identify feeders with better performance for the operation of deferrable loads. They suggest ways that DERs can actively participate in the electricity market by following market signals. The two indexes show how a good feeder responds to market signals without having a negative effect on the distribution network. The new indexes can help utility companies determine an optimal bidding strategy in the day-ahead market, together with the optimal schedules for deferrable loads.
“The indexes proposed in this paper can be combined with field measurements from smart meters at substations to measure in real-time the collective impact distributed energy resources have on distribution system reliability,” Sadeghi-Mobarakeh said.
In addition to Sadeghi-Mobarakeh, the authors include his adviser, Hamed Mohsenian-Rad, a professor of electrical and computer engineering at UC Riverside; Alireza Shahsavari, a doctoral student at UC Riverside; and Hossein Haghighat of Islamic Azad University of Jahrom.
The paper will appear in an upcoming issue of IEEE Transactions on Smart Grid.

https://www.nationalgeographic.com/foodfeatures/feeding-9-billion/
When we think about threats to the environment, we tend to picture cars and smokestacks, not dinner. But the truth is, our need for food poses one of the biggest dangers to the planet.
Agriculture is among the greatest contributors to global warming, emitting more greenhouse gases than all our cars, trucks, trains, and airplanes combined—largely from methane released by cattle and rice farms, nitrous oxide from fertilized fields, and carbon dioxide from the cutting of rain forests to grow crops or raise livestock. Farming is the thirstiest user of our precious water supplies and a major polluter, as runoff from fertilizers and manure disrupts fragile lakes, rivers, and coastal ecosystems across the globe. Agriculture also accelerates the loss of biodiversity. As we’ve cleared areas of grassland and forest for farms, we’ve lost crucial habitat, making agriculture a major driver of wildlife extinction.
The environmental challenges posed by agriculture are huge, and they’ll only become more pressing as we try to meet the growing need for food worldwide. We’ll likely have two billion more mouths to feed by mid-century—more than nine billion people. But sheer population growth isn’t the only reason we’ll need more food. The spread of prosperity across the world, especially in China and India, is driving an increased demand for meat, eggs, and dairy, boosting pressure to grow more corn and soybeans to feed more cattle, pigs, and chickens. If these trends continue, the double whammy of population growth and richer diets will require us to roughly double the amount of crops we grow by 2050.
Unfortunately the debate over how to address the global food challenge has become polarized, pitting conventional agriculture and global commerce against local food systems and organic farms. The arguments can be fierce, and like our politics, we seem to be getting more divided rather than finding common ground. Those who favor conventional agriculture talk about how modern mechanization, irrigation, fertilizers, and improved genetics can increase yields to help meet demand. And they’re right. Meanwhile proponents of local and organic farms counter that the world’s small farmers could increase yields plenty—and help themselves out of poverty—by adopting techniques that improve fertility without synthetic fertilizers and pesticides. They’re right too.
But it needn’t be an either-or proposition. Both approaches offer badly needed solutions; neither one alone gets us there. We would be wise to explore all of the good ideas, whether from organic and local farms or high-tech and conventional farms, and blend the best of both.
I was fortunate to lead a team of scientists who confronted this simple question: How can the world double the availability of food while simultaneously cutting the environmental harm caused by agriculture? After analyzing reams of data on agriculture and the environment, we proposed five steps that could solve the world’s food dilemma.
Step One: Freeze Agriculture’s Footprint
For most of history, whenever we’ve needed to produce more food, we’ve simply cut down forests or plowed grasslands to make more farms. We’ve already cleared an area roughly the size of South America to grow crops. To raise livestock, we’ve taken over even more land, an area roughly the size of Africa. Agriculture’s footprint has caused the loss of whole ecosystems around the globe, including the prairies of North America and the Atlantic forest of Brazil, and tropical forests continue to be cleared at alarming rates. But we can no longer afford to increase food production through agricultural expansion. Trading tropical forest for farmland is one of the most destructive things we do to the environment, and it is rarely done to benefit the 850 million people in the world who are still hungry. Most of the land cleared for agriculture in the tropics does not contribute much to the world’s food security but is instead used to produce cattle, soybeans for livestock, timber, and palm oil. Avoiding further deforestation must be a top priority.
Step Two: Grow More on Farms We’ve Got
Starting in the 1960s, the green revolution increased yields in Asia and Latin America using better crop varieties and more fertilizer, irrigation, and machines—but with major environmental costs. The world can now turn its attention to increasing yields on less productive farmlands—especially in Africa, Latin America, and eastern Europe—where there are “yield gaps” between current production levels and those possible with improved farming practices. Using high-tech, precision farming systems, as well as approaches borrowed from organic farming, we could boost yields in these places several times over.
Step Three: Use Resources More Efficiently
We already have ways to achieve high yields while also dramatically reducing the environmental impacts of conventional farming. The green revolution relied on the intensive—and unsustainable—use of water and fossil-fuel-based chemicals. But commercial farming has started to make huge strides, finding innovative ways to better target the application of fertilizers and pesticides by using computerized tractors equipped with advanced sensors and GPS. Many growers apply customized blends of fertilizer tailored to their exact soil conditions, which helps minimize the runoff of chemicals into nearby waterways.
Organic farming can also greatly reduce the use of water and chemicals—by incorporating cover crops, mulches, and compost to improve soil quality, conserve water, and build up nutrients. Many farmers have also gotten smarter about water, replacing inefficient irrigation systems with more precise methods, like subsurface drip irrigation. Advances in both conventional and organic farming can give us more “crop per drop” from our water and nutrients.
Step Four: Shift Diets
It would be far easier to feed nine billion people by 2050 if more of the crops we grew ended up in human stomachs. Today only 55 percent of the world’s crop calories feed people directly; the rest are fed to livestock (about 36 percent) or turned into biofuels and industrial products (roughly 9 percent). Though many of us consume meat, dairy, and eggs from animals raised on feedlots, only a fraction of the calories in feed given to livestock make their way into the meat and milk that we consume. For every 100 calories of grain we feed animals, we get only about 40 new calories of milk, 22 calories of eggs, 12 of chicken, 10 of pork, or 3 of beef. Finding more efficient ways to grow meat and shifting to less meat-intensive diets—even just switching from grain-fed beef to meats like chicken, pork, or pasture-raised beef—could free up substantial amounts of food across the world. Because people in developing countries are unlikely to eat less meat in the near future, given their newfound prosperity, we can first focus on countries that already have meat-rich diets. Curtailing the use of food crops for biofuels could also go a long way toward enhancing food availability.
Step Five: Reduce Waste
An estimated 25 percent of the world’s food calories and up to 50 percent of total food weight are lost or wasted before they can be consumed. In rich countries most of that waste occurs in homes, restaurants, or supermarkets. In poor countries food is often lost between the farmer and the market, due to unreliable storage and transportation. Consumers in the developed world could reduce waste by taking such simple steps as serving smaller portions, eating leftovers, and encouraging cafeterias, restaurants, and supermarkets to develop waste-reducing measures. Of all of the options for boosting food availability, tackling waste would be one of the most effective.
Taken together, these five steps could more than double the world’s food supplies and dramatically cut the environmental impact of agriculture worldwide. But it won’t be easy. These solutions require a big shift in thinking. For most of our history we have been blinded by the overzealous imperative of more, more, more in agriculture—clearing more land, growing more crops, using more resources. We need to find a balance between producing more food and sustaining the planet for future generations.
This is a pivotal moment when we face unprecedented challenges to food security and the preservation of our global environment. The good news is that we already know what we have to do; we just need to figure out how to do it. Addressing our global food challenges demands that all of us become more thoughtful about the food we put on our plates. We need to make connections between our food and the farmers who grow it, and between our food and the land, watersheds, and climate that sustain us. As we steer our grocery carts down the aisles of our supermarkets, the choices we make will help decide the future.
