Rising Sea Temperatures Force Vattenfall to Close Reactor in Sweden

After reactor 2 at the Swedish Ringhals nuclear power plant had been running at reduced capacity since Monday 30 July, it was closed down completely Tuesday afternoon.

The continued warm weather in Sweden has brought the sea water close to 25 degrees during recent days. To maintain cooling capacity at Ringhals’ production facilities, sea water is used for cooling of various systems and components in the process. The sea water used for cooling Ringhals 2 has now reached a temperature that makes it necessary to take the reactor out of operation.

– When the water becomes warmer, its cooling capacity is reduced and in order for us to keep the necessary cooling capacity for the various systems with a good safety margin, we now have to take Ringhals 2 out of operation, says Sven-Anders Andersson, Head of production at Ringhals.

Ringhals 3 and 4 are still producing normally, and Ringhals 1 is presently closed down for scheduled maintenance. Each reactor has a maximum permissible value for the sea water temperature. For Ringhals 2 it is 25 degrees.

– When, during Monday, we got closer to 25 degrees, we decided to reduce the output to 55 per cent, but now the temperature has increased above 25 degrees and Ringhals 2 is consequently closed down, says Sven-Anders Andersson.

That the sea reaches so high temperature levels this year is very unusual, and that Swedish nuclear power plants need to reduce their output due to too warm sea water is something that only happens rarely. At Ringhals it has only happened at a few instances since the turn of the century.

Our Cellphone Addiction Is Turning Wireless Tech Into an Invisible Weapon That’s Destroying Wildlife

There is growing evidence that our addiction to cellphones could be impacting brain functionality and be the cause of stress, anxiety, insomnia and a lack of attention and focus. Now a new report has found that we’re not the only living things to be affected by our increasing dependence on wireless technology. Mammals, birds, insects and even plants are likely being harmed by the electromagnetic radiation (EMR) emanating from Wi-Fi, cellphone towers, broadcast transmitters and power lines, according to a new analysis of 97 peer-reviewed studies conducted by EKLIPSE, a biodiversity and ecosystem project funded by the European Union.

The researchers said that “evidence is accumulating that mammals (e.g., bats and mice) have a magnetic sense” that is affected by radio-frequency-modulated electromagnetic fields (RF-EMR). Birds in particular may be highly susceptible. The researchers found that even weak magnetic fields in the radio frequency range can disrupt birds’ magnetoreception, their ability to use the Earth’s magnetic fields to orient themselves and find their way home.

Homing pigeons are well-known for their magnetoreception, but this sense has also been detected in other animals, like red foxes, and there is evidence that even large mammals like deer use the planet’s magnetic fields to sense direction. A number of invertebrates, including worms, mollusks and fruit flies also use this ability.

The report also concluded that EMR can also alter the metabolism of plants, causing “significant changes … demonstrated at cellular and molecular levels.” The authors noted that even a low level exposure to EMR “caused a rapid increase in stress-related transcript accumulation in tomato [plants].” Transcription is the first phase in the expression of a gene, in which a specific segment of DNA is copied into RNA.

The authors said that their findings indicate “an urgent need to strengthen the scientific basis of the knowledge on EMR and their potential impacts on wildlife,” specifically calling out the “need to base future research on sound, high-quality, replicable experiments so that credible, transparent and easily accessible evidence can inform society and policy-makers to make decisions and frame their policies.”

The UK charity Buglife (which proposed the analysis) warned that there wasn’t enough research to determine limits to EMR pollution. The group said that “serious impacts on the environment could not be ruled out” and urged that 5G transmitters should not be placed near street lights, which attract nocturnal insects like moths, nor in areas near wildlife.

Buglife CEO Matt Shardlow, who served on the experts steering group of the report, warned that “there is a credible risk that 5G could impact significantly on wildlife.”

Shardlow specifically warned of the current rollout of 5th-generation wireless systems or 5G networks, and called on telecommunications firms to research the impact of their wireless technology on wildlife and make their findings public. In May, Qatar become the first nation in the world to have a 5G network. The worldwide commercial launch of 5G is expected in 2020.

The report authors also said that strong EMR fields increase the temperature in living tissue, but the intensity needed to induce such heating is “not experienced by wildlife (so far).” It’s notable that they left the door open to this other potential emerging threat, as cellphone adoption rates are steadily rising globally. The number of smartphone users worldwide is forecast to grow from 2.1 billion in 2016 to around 2.5 billion in 2019, according to Statista, a market research firm. That means more cell towers—and more EMR being emitted into the environment.

“When you start to observe and realize that swallows and house martins no longer nest in towns and villages, when you realize that the sparrows have all disappeared, that in the evenings there are no bats flying in the dusk and that you no longer hear owls hooting, then you will begin to know what effect microwaves from cell towers and antennas are having on the environment,” said one commenter to a One World News article about the report.

The report comes on the heels of a recent appeal to the United Nations, signed by more than 200 scientists from 41 countries, urging the international body to address the risks posed electromagnetic fields (EMF), physical fields produced by objects charged by electromagnetic fields and radiofrequency radiation. Specifically, the scientists want the UN to “recognize that EMF exposure is an emerging health and environmental crisis that requires a high priority response.”

“Biologists and scientists are not being heard on the committees that set safety standards,” said Dr. Martin Blank of the Department of Physiology and Cellular Biophysics at Columbia University and signatory of the appeal, in a video address on the website of International EMF Alliance, a group founded in 2009 that disseminates information to policymakers and health authorities about the potential effects of electromagnetic radiation. “The biological facts are being ignored and as a result, the safety limits are much too high. They are not protective.”

Though evidence is mounting that humans may also be physiologically affected by EMF, the jury is still out on the impact of long-term low-frequency exposure. The World Health Organization (WHO) concluded that “current evidence does not confirm the existence of any health consequences from exposure to low level electromagnetic fields.” However, the agency does admit that “some gaps in knowledge about biological effects exist and need further research.”

Europe’s Microwave Ovens Emit Nearly As Much CO2 As 7m Cars

The biggest impact comes from electricity used to power the microwaves, but study also highlights rising environmental cost of our throwaway culture.

Popping frozen peas into the microwave for a couple of minutes may seem utterly harmless, but Europe’s stock of these quick-cook ovens emit as much carbon as nearly 7m cars, a new study has found.
And the problem is growing: with costs falling and kitchen appliances becoming “status” items, owners are throwing away microwaves after an average of eight years, pushing rising sales.

A study by the University of Manchester worked out the emissions of carbon dioxide – the main greenhouse gas responsible for climate change – at every stage of microwaves, from manufacture to waste disposal.

“It is electricity consumption by microwaves that has the biggest impact on the environment,” say the authors, who also calculate that the emissions from using 19 microwaves over a year are the same as those from a car.
“Efforts to reduce consumption should focus on improving consumer awareness and behaviour to use appliances more efficiently. For example, electricity consumption by microwaves can be reduced by adjusting the time of cooking to the type of food.”

Each year more microwaves are sold than any other type of oven in the EU: annual sales are expected to reach 135m by the end of the decade.

David Reay, professor of carbon management at the University of Edinburgh, pointed out that the damage done by microwaves is still a fraction of that done by cars. “Yes, there are a lot of microwaves in the EU, and yes they use electricity,” he said.
“But their emissions are dwarfed by those from cars – there are around 30m cars in the UK alone and these emit way more than all the emissions from microwaves in the EU. Latest data show that passenger cars in the UK emitted 69m tonnes of CO2 equivalent in 2015. This is 10 times the amount this new microwave oven study estimates for annual emissions for all the microwave ovens in the whole of the EU.”

The energy used by microwaves is lower than any other form of cooking. uSwitch, the price comparison website, lists microwaves as the most energy efficient, followed by a hob and finally an oven, advising readers to buy a microwave if they don’t have one. However, they urge owners to switch them off at the wall after use, to avoid powering the clock.
“Yes, it’s important to use microwaves efficiently,” said Simon Bullock, senior climate change campaigner for the charity Friends of the Earth. “But so is making sure the electricity that powers them is as low pollution as possible. The government should reverse its policy attacks on solar and onshore wind. We need green electrons powering all the nation’s tellies, microwaves and fridges.”
Alejandro Gallego-Schmid, one of the report’s authors, said: “The aim of our study was not to compare microwaves to other cooking appliances but to look at the environmental impacts of microwaves as ubiquitous devices in households in Europe and draw attention to the need to make their design, use and end-of-life waste management more efficient.”

Lemurs Are the Most Endangered Species of Primate on the Planet

Photo-illustration: Pixabay

Approximately 94% of the 111 species and subspecies of lemur are under threat of extinction in their native country of Madagascar – the only place they exist outside of captivity. Of the remaining lemur groups, only six do not face high risk of extinction, according to the International Union for the Conservation of Nature’s (IUCN) Red List of Threatened Species. This retrogression was revealed by the Primate Specialist Group, a conservation organization that has been analyzing current threats to the survival of lemur populations and their habitats.

Chair of the Primate Specialist Group and Chief Conservation Officer of Global Wildlife Conservation Russ Mittermeier indicated that the “very high extinction risk to Madagascar’s unique lemurs” would compound, generating “grave threats to Madagascar’s biodiversity as a whole.” Loss of habitat poses the single greatest threat the lemurs now face in the wild. Developments in illegal logging and slash-and-burn agriculture, as well as mining activities and charcoal production, are ultimately determining the fate of these endangered animals.

Lemurs also face threats from pet trading hobbyists or hunters who wish to turn them into food. Once a delicacy, lemur’s presence on menus has become more and more mainstream in Madagascar, according to Professor Christoph Schweitzer of the Bristol Zoological Society. In an interview with BBC News, Schwitzer commented, “More and more, we are seeing unsustainable levels of lemur poaching. We see commercial hunting as well – probably for local restaurants. And this is a new phenomenon for Madagascar – we didn’t see it at this scale 15 years ago”

Although many would bow their heads at the unfortunate fate of the lemurs, Schwitzer is an optimist. People “need to shout about these problems and get the message out there” he remarked. “When we published the lemur action plan and the media picked up on it, suddenly we had people call offering to help – to donate money or other resources. That can really make a difference,” he remarked. The “lemur action plan” has already had an effect, protecting habitats that contain the densest numbers of lemur species while helping Madagascar boost its ecotourism in the hopes of tackling poverty. By helping the local people economically, the groups involved in the plan are deterring hunting and other activities destructive to the tropical forests that provide the lemurs with their natural habitat.

Porsche has announced it is to launch its first electric car in 2019.

It claims the 600bhp battery-powered Taycan will be able to accelerate to 62mph in under 3.5 seconds and drive for 310 miles between charges, all while producing no emissions.

The automaker says the sports car will use two ‘permanently excited’ synchronous motors, which are seen as the turbochargers of electric motoring, to generate a constant rotary motion that can be applied at any time without needing to be started.

It currently forecasts production rates of twenty thousand units a year, equivalent to roughly two-thirds of the current sales figures for the 911.

Porsche says it wants to shift to electromobility before all other German auto manufacturers and by 2025 aims for every second Porsche sold to have an an electric drive unit.

To achieve this, the firm, which already uses 100% green energy at its German production facilities, has committed to investing €6 billion (£5.3bn) in electromobility before 2022.

5,500 UK Churches Switch to Renewable Energy

More than 5,500 churches including some of the UK’s most famous cathedrals have converted to renewable power to help tackle climate change.

Church of England places of worship, along with Catholic, Baptist, Methodist, Quaker and Salvation Army congregations, have made the switch to 100% renewable electricity, and faith leaders are urging more to follow suit.

Fifteen Anglican cathedrals including Salisbury, Southwark, St Albans, Liverpool, Coventry and York Minster are among the buildings signed up to green electricity tariffs.

Church leaders said climate change was “one of the great moral challenges of our time” and hurt the poor first and worst.

With the average annual church electricity bill around £1,000, British churches have diverted more than £5m from fossil fuels to clean energy providers, it is estimated.

The number of cathedrals running on 100% renewable electricity is down to the Church of England’s procurement group, Parish Buying.

Other churches have made the move through the Big Church Switch campaign run by the Christian charities Christian Aid and Tearfund and the Church of England’s environment programme.

Parishes can sign up with the national church buying group 2buy2, which pools the combined buying power to negotiate the cheapest possible tariff. Christian Aid said the renewable energy tariff was often cheaper than the fossil fuel-dominated one they had been on before.

Nicholas Holtam, the bishop of Salisbury and the Church of England’s lead bishop on the environment, said: “It’s fantastic to see churches doing their bit to ensure they reduce their impact on the environment. They are also giving a boost to clean energy, which is essential to reduce harmful carbon emissions.

“Climate change is an enormous injustice and is hurting the poor first and worst. Switching to responsible sources of electricity may seem like a small thing on its own, but when joined together it can make a real difference.”

Rowan Williams, the former archbishop of Canterbury and the chair of Christian Aid, said the Church of England had agreed to sell its shares in fossil fuel companies not on track to meet the aims of the Paris agreement on tackling climate change.

“Churches are part of a global network and so are often very aware of the plight of our brothers and sisters suffering from droughts, floods and extreme weather around the world,” he said.

He urged the government to set a target to cut UK emissions to zero by 2050 to ensure Britain “remains a green and pleasant land at home and a climate leader abroad”.

Global Wind and Solar Installations Break 1TW Milestone

Wind generation made up around 54% of this figure, with the solar proportion coming in at 46%.

The volume of wind and solar energy capacity installed around the world has broken the 1TW milestone.

That’s according to a new report from Bloomberg New Energy Finance (BNEF), which predicts this will double by mid-2023, with the second 1TW expected to cost 46% less to build than the first 1TW.

BNEF estimates the first 1TW of wind and solar required approximately $2.3 trillion (£1.77tn) of capital expenditure to deploy – it says expenditure on wind and solar generation between now and 2023 is likely to total about $1.2 trillion (£920bn).

Wind generation made up around 54% of the 1TW installed so far, with solar making up the other 46%. The report suggests installed solar capacity will shortly overtake that of wind. Total installed capacity for both energy sources has grown 65-fold since the year 2000 and more than quadrupled since 2010.

The BNEF report said: “In our 2013 Global Renewable Energy Market Outlook we estimated that global wind and solar installations would hit 865GW by the end of 2017 and get very close to 1,000GW by the end of 2018.

“In actual fact, the world had hit 945GW by end-2017, thus outperforming our expectations by 9% and hit 1,000GW about six months earlier than we forecast. In other words, we were very close but not quite aggressive enough.”

Temperatures in South-West Europe Could Break 48C Record This Weekend

Large parts of southern and western Europe are expected to experience high temperatures this weekend with forecasters warning that thermometers could reach up to 48C in Spain.

Holidaymakers bound for the Iberian peninsula have been warned to expect extreme heat, with the chance of the hottest temperatures ever recorded in continental Europe.

The current record of 48C in Athens, Greece, in 1977, could be broken as waves of blisteringly hot air sweep in from Africa.

Temperatures around the Mediterranean are expected to rise and peak at the weekend, with the highs expected inland rather than in coastal areas, after edging into the low-40s on Wednesday and Thursday.

“These sorts of temperatures are not only exceptional for the locals but people from the UK will never really have experienced them,” said Luke Miall, a UK Met Office meteorologist.

“Especially with it being the school holidays, and the very young and old being susceptible to heatstroke, we’re advising tourists to keep out of the midday sun and protect themselves.”

Temperatures in south-west France could also rise to the high 30s, he added.

In the UK the mercury is set to be significantly lower this weekend although temperatures of up to 31C are forecast in London and the south-east.

Sunshine will return to most of the country but the north of England, Scotland and Northern Ireland will enjoy temperatures in the mid-20s along with scatterings of rain.

The UK has seen its driest first half of summer on record, while last month was the third hottest July ever recorded, but much of the country had cool, wet, windy weather last weekend.

Meanwhile, the UK Environment Agency said it would allow farmers more flexibility in taking water from rivers in the face of threats to crops and livestock after frustrated farming leaders and officials convened a “drought summit” on Wednesday.

The prolonged hot spell has devastated wheat fields across northern Europe prompting observers to cut crop estimates across the European Union, collectively the world’s largest wheat grower, to a six-year low.

Looking ahead to chillier times, the department store Selfridges has defied the return of the heatwave to open its Christmas shop for those already craving some festive winter cheer.

The department store has declared it is once again the first in the world to unveil its Christmas section – 145 days ahead of the event itself – with shelves already loaded with tinsel, glitter and baubles decorated in the hues of a frosty morning.

“We have so many customers visiting from all over the world, eager to snap up festive decorations and souvenirs on their London summer holidays which they can’t buy at home,” said Selfridges buyer Eleanor Gregory.

“Our summer Christmas shop launch simply addresses the growing demand for convenience Christmas shopping outside the traditional Christmas season from many of our customers.”

Finland has launched its first electric plane, which it hopes will clean up airborne pollution and slash fuel costs.

The Electric Aviation Association is partnering with Finnish airport operator Finavia to use the Slovenian-made Pipistrel Alpha Electro planes, which would be used for training and could cut carbon emissions by as much as 80%.

The organisations says electric aviation is comparatively cheap, with the Alpha Electro costing around €150,000 (£133,500).

They expect low carbon flight will become increasingly important for Finland’s domestic air traffic and even suggest the vehicles could be used as airborne taxis.

Janne Vasama, President of the Helsinki Electric Aviation Association, said: “This is the first step toward more ecological transport in Finland’s future.

“At the moment, the biggest costs in aviation are fuel and maintenance. With electric planes, these are both only about one tenth of what they are for regular planes.”

Study Finds New Reason to Ban Plastic: It Emits Methane in the Sun

Photo-illustration: Pixabay

The proliferation of plastic pollution has led to concerns over its impact on marine life and human health as the toxins it absorbs and emits move up the food chain. Now, a new study reveals yet another potential plastic hazard: It releases greenhouse gasses.

Photo-illustration: Pixabay

The study, published in PLOS One Wednesday, found that some of the most common plastics in the environment release the greenhouse gasses methane and ethylene when exposed to sunlight.

While the amounts released by the plastics are small, researchers are concerned that the scale of plastic production and waste means they could still contribute to climate-changing greenhouse gas emissions over time.

“Considering the amounts of plastic washing ashore on our coastlines and the amount of plastic exposed to ambient conditions, our finding provides further evidence that we need to stop plastic production at the source, especially single use plastic,” lead author Dr. Sarah-Jeanne Royer said in a University of Hawaii press release.

Royer didn’t set out to study plastics, BBC News reported. Instead, she was measuring the methane produced by biological organisms in sea water when she discovered that more methane was coming from the plastic bottles holding the samples.

“It was a totally unexpected discovery,” she told BBC News.

Her University of Hawaii research team went on to test polycarbonate, acrylic, polypropylene, polyethylene terephthalate, polystyrene, high-density polyethylene and low-density polyethylene (LDPE), which are used commonly in food packaging, textiles, construction and other plastic goods, according to the University of Hawaii.

Polyethylene, which is used in plastic bags and is the most used and discarded plastic in the world, emitted the largest amounts of the greenhouse gasses.

After being exposed to sunlight for 212 days, LDPE emitted 176 times the methane that it had at the start of the experiment, BBC News reported.

This is because, when the plastic is exposed to sunlight, it breaks down, cracking and exposing more plastic area to the sun, which leads to greater gas emission.

Once LDPE had been exposed to the sun, it continued to emit gases even in darkness, the study found.

LDPE waste pulled from the ocean also emitted greenhouse gasses when laid out in sunlight.

While it was known that plastic releases carbon dioxide when it degrades, this is the first research to measure the emission of other greenhouse gasses.

“Research on plastic waste is revealing it to be a disturbing pandora’s box,” University of Geneva chemist Dr. Montserrat Filella, who was not involved with the research, told BBC News. “As research expands our knowledge, we are realising that plastics can be insidious in many other ways. For instance, as vectors of ‘hidden pollutants,’ such as heavy metals present in them or, now, as a source of greenhouse gases. And, in all cases, throughout the entire lifetime of the plastic.”

Royer is now working on estimating the amount of plastic exposed to sun globally so that she can find ways to limit its contribution to the greenhouse gas emissions that cause climate change, according to the University of Hawaii.

Children Increasingly Travelling to School by Car, Despite Pollution Dears

The percentage of primary school children walking or riding bikes to their place of education fell by 2% last year.

The number of parents driving their children to school is growing, despite increasing concerns about the impact of air pollution around such areas.
That’s according to new statistics released by the government illustrating the proportion of people using different forms of transport to travel around England.
The report shows the percentage of primary school children walking or riding bikes to their place of education fell from 53% to 51% last year, even though the dangers of cars idling around school gates are becoming increasingly well-known.

Campaigners suggest this seems to contradict moves such as the Mayor of London’s £1 million fund to help 50 schools in London’s most polluted areas reduce the affects of poor air quality.

The government study also reveals an increase in the number of people using cars or vans instead of walking for journeys of less than two miles.
In terms of overall mobility, the report shows the steady decrease in the number of trips and miles travelled since the late-1990s has been reversed – there was an increase in the average number of trips and the average miles travelled per person in the two years from 2015 to 2017.

Global Water Market to Grow to $915bn by 2023’

It has been linked to high commodity and oil prices as well as major water quality and infrastructure plans.

The global water market is projected to grow to nearly $915 billion (£700bn) over the next five years.
That’s amid a recovering global economy, high commodity and oil prices and major water quality and infrastructure plans such as those in Saudi Arabia, China and Southeast Asia aimed at improving wastewater treatment and incentivising private finance in water, according to Global Water Intelligence (GWI).

The water market is currently worth around $770 billion (£789bn), which includes both the operating and capital expenditures of utilities and industrial water users.
The projected increase in global spending on water and wastewater is said to be fuelled by a return to growth for key industry sectors such as mining and upstream oil and gas.

The GWI states commodity and oil prices experienced a rebound last year off the back of the OPEC production cuts and a growing demand for commodities such as copper, lithium and nickel as a result of an increased in demand for batteries and electric vehicles (EVs).

It adds: “GWI’s analysists have forecast increases in spending on water and wastewater treatment systems, particularly in the oil and gas and mining sectors, over the next five years.
“The market for oil-water separation technologies for instance, is forecast to grow by 14.6%, bringing new opportunities for technology suppliers and specialists in water management and treatment. Rising oil prices are facilitating a boom in the North American fracking industry and the renewed exploitation of mature fields like the Permian Basin which increasingly have high water management and treatment requirements. GWI found that the average number of waste barrels used per frack in the Permian Basin increased 434% between 2013-2016.”

Sweden’s Highest Point Set to Lose Title as Glacier Melts

Glacier on the southern tip of Kebnekaise mountain shrinks due to record Arctic temperatures.

Sweden’s highest peak, a glacier on the southern tip of the Kebnekaise mountain, is melting due to record hot Arctic temperatures and is no longer the nation’s tallest point, scientists said on Wednesday. “I’ve never seen this much melted snow on the southern peak as I did this summer,” said Gunhild Rosqvist, a Stockholm University geography professor.

Rosqvist, who is also head of the Tarfala research station near the mountain, has been measuring the southern peak for many years as part of climate change research. Kebnekaise, a popular tourist destination located in Sweden’s far north, has two main peaks – a southern one covered by a glacier and a northern one free of ice.
Rosqvist said the southern peak has lost four metres (13ft) of snow between 2 July and 31 July. This means an average of 14cm of snow melted every day on the glacier in July, as Sweden experienced record hot temperatures, triggering dozens of wildfires across the country, even in the Arctic Circle.
“This is happening very fast. The result of this hot summer will be a record loss in snow and ice in the mountains,” Rosqvist said.

At its latest measurement, the southern peak reached 2,097 metres above sea level, just 20cm higher than the northern tip’s 2096.8 metres. “The forecast is that as of 1 August the southern peak is going to be lower than the northern peak,” Rosqvist said.
Last year, the difference between the two peaks was two metres. The southern glacier, whose height has been measured since 1880, has been melting by one metre each year in the past two decades, according to Stockholm University.

The new zero emission vehicles are able to cover a 300-mile range on a full tank of the gas.

Toyota has unveiled a new hydrogen fuel cell electric freight truck able to cover a 300-mile range on a full tank.
The new vehicle, codenamed Beta, expands the capabilities of Toyota’s port operations (drayage) test vehicle it has been trialling at the ports of Long Beach and Los Angeles since last April.

The original Alpha model, which has a range of 200 miles, has already logged more than 10,000 miles in testing, emitting nothing other than water vapour.
Beta will enter service in the autumn, increasing the ports’ zero emission trucking capacity and further reducing the environmental impact of the haulage operations.

More than 16,000 pollution-emitting trucks service the ports of Long Beach and Los Angeles, a number that is expected to double by 2030.
More than 43,000 drayage trucks are working across similar facilities in the US, sending significant amounts of carcinogens, diesel particulates and other substances into the atmosphere.

Craig Scott, Senior Manager for Toyota’s North American Electrified Vehicle and Technologies Office, said: “Our goal with the first truck was to see if it could be accomplished and we did that.
“This time we’re looking at commercial viability. We want to help make a significant difference when it comes to the air quality not only in the Los Angeles area but across the US and around the globe.”

World’s Largest King Penguin Colony Collapses by almost 90% in Space of 35 years

Number of pairs has fallen from 500,000 in the 1980s, to just 60,000 by 2017.

The world’s largest colony of king penguins has collapsed by almost 90 per cent over the last 35 years, new research indicates.

Aerial and satellite images of the colony living on the remote subantarctic island of Île aux Cochons, in the southern Indian Ocean, suggests the number of penguins has fallen from around 500,000 pairs in the 1980s, to just 60,000 pairs in photographs taken in 2015 and 2017.
Until now, it was regarded as the second-largest colony of penguins in the world, after one on Zavodovski Island in the South Sandwich Islands, where the slopes of an active volcano are home to around two million chinstrap penguins.

Scientists have not yet identified why the population of king penguins on Île aux Cochons has shrunk so dramatically, but they noted that it is not possible for the birds have migrated elsewhere, as there are no other islands suitable for them to inhabit within striking distance.

In a paper published in the journal Antarctic Science, the authors say “possible causes were explored but no plausible explanation for such an unprecedented decrease in penguin populations was found”.
Satellite imagery shows the extent of the penguins’ breeding area, on bare flat ground, has also reduced significantly as vegetation has recolonised the stony ground.
Though they remain unsure of the cause, the team has suggested several possible hypothesis for the “massive decline”.

The first relates to the Indian Ocean Dipole, a weather phenomenon which affects ocean temperatures, local atmosphere and rainfall. In 1997 a particularly strong event may have sent fish and squid further south, affecting the foraging capacities of the penguins, leading to poor breeding performance from which the colony has struggled to recover.

The Dipole is closely associated with El Niño events, which have been amplified by global warming.
Another theory is that the decline may have been spurred by a partial relocation of the colony from a large group on one part of the island, to a smaller, beach-based colony, first observed in 1995.
Though the paper notes that the size of this newer population – 17,000 pairs – accounts only for a fraction of the original colony.

Third, feral cats and house mice, known to be present on the Île aux Cochons, may have changed their behaviour and may have begun to attack penguin chicks. This behavioural change has been observed in the past, where mice and cats were recorded beginning to target albatross chicks.
The fourth hypothesis is that diseases or parasites which affect various species of seabirds could have hit the colony, reducing breeding success, the survival of adults and population growth rates.

However, the paper says that the extent of the collapse would be unprecedented if it were the result of disease outbreak.
The last human visit to the island was back in 1982, and the team is now planning to return to study the causes for the decline.

The Startup Making Shirts out of Cow Poo

Cow waste is a global environmental issue. Jalila Essaïdi and Dutch farmers are tackling the problem by transforming manure into materials.

Would you buy a shirt that has been through the back end of a cow? This could be a future fabric choice according to one Dutch startup, which is extracting cellulose from cowpats to make “manure couture”.

Jalila Essaïdi believes that a non-vegan future will involve recycling cow manure into cellulose fibre, bioplastics, chemical concentrates and pure water – and being less squeamish about it, too.
“Like a lasagne of manure, you need to make something out of it,” she says. “We see manure as a waste material, something disgusting and smelly. But oil [used to make fibre] isn’t clean and beautiful at the beginning. You really have to show people the hidden beauty if you transform this cellulose.”
It is just one of a range of innovations seeking new materials for old applications, as the world tries to wean itself off dirty habits like plastics and hydrocarbons and embrace new technologies.

Biocouture has in fact been around for several years but faces problems of scalability.
Essaïdi, who is working with 15 farmers in Eindhoven to create an industrial-scale manure refinery this year, has already won awards for her innovation including $200,000 from the Chivas Venture and an H&M Foundation Global Change award.
“The process is chemical and mechanical,” she explains, having run trials to create a fashion show in 2016. “When you collect manure, it’s a combination of urine and cow poop, 80% water. We separate the dry and wet fraction. The wet fraction is fermented and we [extract] solvents to transform the cellulose, which is nothing other than the grass and corn the cows eat.

“What makes our process better than the normal textile industry Croftmethod is that we don’t need high pressure, as the cow stomach is the first step in making the fibre softer. It’s also more energy efficient.”

Cow waste is an international environmental issue: in New Zealand, an estimated 60% of waterways are unsafe for swimming due to runoff from dairy farms full of algae-promoting nitrates, phosphates and bacteria. The EU has limits on manure used as fertiliser, to reduce water pollution, but in dairy lands like the Netherlands, there are regular reports of organised “manure fraud”.
The Dutch government’s environmental agency estimates 30%-40% of the country’s 76bn annual kilos of manure enters a black market of illegal waste, secretly traded or spread on the land at night to avoid fines for overproduction.

Kim Roetert, public affairs spokeswoman for the ZLTO farmers’ association, believes manure is an inevitable side-effect of animal farming but too much is a real problem. “Just seeing it as a waste product shows limited vision, though,” she says. “Manure has a lot of value, not just in making the ground fertile, but also, as Mestic is doing, making textiles, paper and bioplastic … or bio-energy. There would be no reason for farmers to commit manure fraud if it were no longer a waste product.”

H&M Foundation, established by the clothing retailer H&M, reckons we will have to get used to such unusual source materials. “The world is already consuming the equivalent of approximately 1.6 planet’s worth of resources every year, and there is an urgent opportunity to shift to a model where valuable materials are recovered,” says communications manager Malin Björne. “Fashionista or not, we are all going to have to get used to sometimes unconventional materials as we cannot rely on cotton, for example.”
H&M won’t comment on whether it would produce clothes with Mestic, but other manufacturers have told Essaïdi that they would consider using the cost-efficient fabric – but would not declare it explicitly on clothing labels.
Some academics believe cellulose taken from dung has even more high-tech potential thanks to the quadruple-bellied digestion power of a cow.

Prof Alexander Bismarck, head of the polymer group at the University of Vienna, is working on creating ultra-thin nanocellulose, for instance – although he had to start with elephant dung because none of his students would initially work with cowpats.

“The beauty with an animal is that it’s collecting low-grade biomass, processing it for you, regurgitating, [then] acid and enzymes attack the cellulose and it comes out in the back in quite fine fibres,” he explains. “You expend much less energy in grinding down this cellulose to nanofibers. If you can make thinner paper for printed circuit boards, so your computer or iPhone is lighter, I don’t think the public will mind if the product came out of the back end of an animal.”

The key question with manure couture, though, is whether the fabric smells. When the Dutch television channel RTL Nieuws took Mestic on to the streets, some people – after sniffing it – said they wouldn’t mind putting it on.
Some are more sceptical. Jan Willem van der Schans of Wageningen University, a sustainable livestock farming expert, believes even such innovations are not enough. “This will not solve the beef and dairy problem [of] gastric methane emissions,” he says. “It makes a ‘dead end’ technology less bad, so one could argue that it extends the lifetime of a wrong production system.”
And what about the farmer? Hans Huijbers, chair of the farmers’ associaiton ZLTO which is working with Mestic, wouldn’t mind wearing it. “If I’ve been busy in my cowshed, then I’m already coated in manure!”
