LED Lighting – Health Concerns

 

By Dr. Mercola

Can light affect your health? In this interview, Dr. Alexander Wunsch, a world class expert on photobiology, shares the hidden dangers of light-emitting diode (LED) lighting that most people are completely unaware of.

In fact, this could potentially be one of the most important video interviews I’ve done, as it has enormous impacts — not only on preventing blindness as you age but it is also a pervasive hidden risk factor for sabotaging your health.

Largely as a result of energy efficiency, there’s been a major transition to using LED as a primary indoor light source. In this regard, it worked like a charm, reducing energy requirements by as much as 95 percent compared to incandescent thermal analogue sources of lighting.

However, the heat generated by incandescent light bulbs, which is infrared radiation, is actually beneficial to your health, and hence worth the extra cost.

There are major downsides to LEDs that are not fully appreciated. LED lighting may actually be one of the most important, non-native EMF radiation exposures you’re exposed to on a daily basis.

If you chose to ignore these new insights, it can have very serious long-term ramifications. It could lead to age-related macular degeneration (AMD), which is the leading cause of blindness in the United States and elsewhere.

Other health problems rooted in mitochondrial dysfunction may also be exacerbated, and these run the gamut from metabolic disorder to cancer.

Glacial Rebound

As contentious debate on the impact of global warming drives on, something unique is occurring in the coastal areas of Alaska. Rather than rising sea levels and diminishing coastlines, the land in southeast Alaska is rising out of the ocean at an accelerated rate. This phenomenon is known as post-glacial rebound or isostatic adjustment, and is a direct result of global warming. The region was once covered by vast glaciers and ice fields, which massively deformed and submerged the coastal landscape. As global temperatures rise, the weight of glacial ice is rapidly melting away, and previously buried land is bursting forth into view.

This series is composed of photographs of the extant Alaskan landscape …… (text omitted)

This project serves as a reminder that the world often fails to conform to our polarized understanding of human-environmental interaction. As political battles rage over the possibility of coastal inundation, these pieces speak to the complexity of the natural world. The contrast of the potential topographies of the future with the natural landscapes of the present challenges the simplified arguments on both sides of the climate change debate. The pieces seek to expand the discourse, while grounding it in the concrete and complex reality of our Earth.

Rabbit-hutch Britain: Growing health concerns as UK sets record for smallest properties in Europe

JONATHAN BROWN – THE INDEPENDENT

Wednesday 18 June 2014

Cramped Living Accommodation

Britain is in the grip of an invisible housing squeeze with millions of people living in homes that are too small for them, according to new research which reveals that more than half of all dwellings are failing to meet minimum modern standards on size.

The poorest households are being hit hardest, with estimates suggesting that four-fifths of those affected by the Coalition’s “bedroom tax” are already forced to contend with a shortage of space, the Cambridge University study found.

The findings will put pressure on the Government, which announced it was to develop a national space standard – although this will only be enforced where it does not impinge on development. Critics argue that the UK already has the smallest properties in Europe following the end of national guidelines in 1980. But soaring land and property prices and a shortage of new homes are fuelling overcrowding, which causes health problems including depression, insomnia and asthma.

The authors of the study – based on an analysis of 16,000 homes in England – said the findings showed the bedroom tax was “fundamentally flawed”. The study argues that, when analysed by floor space instead of the number of rooms, 55 per cent of all homes fail to meet enhanced minimum guidelines laid down by the London Housing Design Guide. This was introduced by the London Authority in 2011 to improve the quality of accommodation in the capital, but has come to be seen as the industry-wide standard.

When analysed by number of current occupants, one home in five is too small. And the problem of too many undersized properties would be much more serious if it were not for low occupation rates caused by increased numbers of single-person households.

Worst affected were flats and terraced houses with children, whilst the study suggested that 79 per cent of homes were either near or below acceptable size.

The average floor space for a dwelling in the UK as a whole is currently 85 sq metres, whilst new-builds average only 76 sq metres – putting Britain at the bottom of a league table of 15 countries including Ireland, Portugal and Italy.

The paper, in the journal Building Research & Information, said that the extent of the problem was not fully understood. Up to a third of householders were said to be unhappy with where they lived. “The majority of homes in the UK are not fully occupied and yet residents are dissatisfied with the amount of space, with lack of storage space, insufficient space for furniture and lack of space in which to socialise often cited as particular problems,” said the authors Malcolm Morgan and Heather Cruickshank.

Mr Morgan, who led the research, said many people found themselves in what was described as a three-bedroom property but which only had the floor space of a two-bedroom place under the London standards. Box rooms categorised as bedrooms were only of use as storage spaces or studies.

The bedroom tax looks at the number of bedrooms, and not at the total available space per person. But the study found that “only 19 per cent of households losing housing benefit (under the bedroom tax) could be considered to have more space than they needed.”

The president of the Royal Institute of British Architects Stephen Hodder said the average new one-bedroom property measuring just 46 sq metres was the same size as a London Underground carriage. “This is depriving households of the space they need to live comfortably and cohesively,” he said.

“Space for children to do their homework, private areas for rest or relaxation and even space to store food and the vacuum are all major concerns in British homes. With a failing housing market, we need to empower our local authorities to borrow money and build quality homes,” he added.

But the Home Builders Federation said market forces, most particularly the price of land, dictated the cost and size of new homes. Steve Turner, a spokesman, said: “House builders have to provide a choice. There are plenty of large homes available on the market and there are smaller ones to cater for people on a smaller budget. If you say all homes have to be a certain size it will exclude a lot of people.”

Rachel Fisher, head of policy at the National Housing Federation, said: “This is evidence that the bedroom tax is not working. It is not making better use of social housing stock because the imbalance between the distribution of households and homes means that in many parts of the country perfectly usable homes are lying empty.”

A Department for Work and Pensions spokesman said: “The fact is that before our reforms taxpayers were funding 820,000 spare bedrooms in working age households in the social rented sector. The removal of the spare-room subsidy is a fair reform so the taxpayer no longer pays for people’s spare bedrooms, while over 300,000 people continue to live in overcrowded homes and 1.7 million sit on council waiting lists.”

CLIMATE CHANGE – Know The Facts

Most my design projects involve solutions and construction methods that mitigate for Climate Change.  Whether we agree with the imposed methodology or not, we are obliged to meet certain mandatory Government Standards during construction as legislators set targets that aim to reduce Carbon Emissions.  These Construction Standards are monitored by Building Control.   It would be very easy for us, (and less time consuming) to follow blindly the rules without any in depth knowledge of the facts behind Climate Change.  However,  I consider we have a duty to advise properly based on a clear understanding of the global issues.  What I call joined-up-thinking or the Gaia Principle.  Only then can we make a difference that is effective.

I have very mixed feelings about the current effectiveness of our Climate Change Mitigation methods for many different reasons.  In particular because we are discouraged by our specialisations from looking at the broader picture which is judged as being beyond our remit.

The technological insight, at the top that produces legislation is seldom shared by those at the sharp end constructing houses or by clients paying the bill.  Hence mitigation is often watered down as people try to navigate round very complex and expensive demands with a very modest understanding of the issues and a limited budget.  And there is far too much reliance on a technology that out-strips our technical knowledge.  Control systems are now invisible – hidden in binary code and inside chips.  As a result systems that are too complex and unfathomable are used inefficiently so that valuable materials and opportunities are squandered.  In the end the real benefits are often too small to be significant.  

A simple example of counter-productive Green Wash was the flooding of the market with mercury loaded (toxic) low energy lamps that were a knee jerk reaction to the need to cut Carbon Emissions. How many millions went to landfill?  And another – the production of Solar lights made of stainless steel and complex components that fail because they are made so cheaply and with built in obsolescence – the same mindset that got us into this sorry state in the first place.   So we do not simply bow to legislation and where we think it won’t work we do not apply it.  

Skepticism and/or indifference plays a huge part in forming prejudiced attitudes towards building to any effective standard.  Most builders just want to get the job done without losing money.  Most clients want the end result for a sensible price.   And we, as designers, can only advise and inform.   The impact we can have as a single operator, in constructing to a higher standard, is minuscule and a huge tax on the end user that is often not value for money.  So are we being sold a hysterical and misguided tale of woe for some hidden agenda or is Climate Change a fact we really need to do something about?

(Article) The Conversion of a Climate-Change Sceptic

The New York Times – THE OPINION PAGES

By RICHARD A. MULLER

Published: July 28, 2012

CALL me a converted sceptic. Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause.

My total turnaround, in such a short time, is the result of careful and objective analysis by the Berkeley Earth Surface Temperature project, which I founded with my daughter Elizabeth. Our results show that the average temperature of the earth’s land has risen by two and a half degrees Fahrenheit over the past 250 years, including an increase of one and a half degrees over the most recent 50 years. Moreover, it appears likely that essentially all of this increase results from the human emission of greenhouse gases.

Injection Wells: The Poison Beneath Us

SOURCED: by Abrahm Lustgarten ProPublica, June 21, 2012, 9:20 a.m.

Over the past several decades, U.S. industries have injected more than 30 trillion gallons of toxic liquid deep into the earth, using broad expanses of the nation’s geology as an invisible dumping ground.

No company would be allowed to pour such dangerous chemicals into the rivers or onto the soil. But until recently, scientists and environmental officials have assumed that deep layers of rock beneath the earth would safely entomb the waste for millennia.

There are growing signs they were mistaken.

Records from disparate corners of the United States show that wells drilled to bury this waste deep beneath the ground have repeatedly leaked, sending dangerous chemicals and waste gurgling to the surface or, on occasion, seeping into shallow aquifers that store a significant portion of the nation’s drinking water.
