Why do we offer safe fabrics?

3 10 2016

Why do we say we want to change the textile industry?  Why do we say we want to produce fabrics in ways that are non-toxic, ethical and sustainable?  What could be so bad about the fabrics we live with?

The textile industry is enormous, and because of its size its impacts are profound.  It uses a lot of three ingredients:

  • Water
  • Chemicals
  • Energy

Water was not included in the 1947 UN Universal Declaration of Human Rights because at the time it wasn’t perceived as having a human rights dimension. Yet today, corporate interests are controlling water, and what is known as the global water justice movement is working hard to ensure the right to water as a basic human right.(1) Our global supply of fresh water is diminishing – 2/3 of the world’s population is projected to face water scarcity by 2025, according to the UN. Our global water consumption rose six fold between 1900 and 1995 – more than double the rate of population growth – and it’s still growing as farming, industry and domestic demand all increase.

The textile industry uses vast amounts of water throughout all processing operations.  Almost all dyes, specialty chemicals and finishing chemicals are applied to textiles in water baths.  Most fabric preparation steps, including desizing, scouring, and bleaching use water.  And each one of these steps must be followed by a thorough washing of the fabric to remove all chemicals used before moving on to the next step.  The water is usually returned to our ecosystem without treatment – meaning that the wastewater, which is returned to our streams, contains all of the process chemicals used during milling.  This pollutes the groundwater.  As the pollution increases, the first thing that happens is that the amount of useable water declines.  But the health of people depending on that water is also at risk, as is the health of the entire ecosystem.

With no controls in place to speak of to date, there are now 405 dead zones in our oceans.  Drinking water even in industrialized countries, with treatment in place, nevertheless yields a list of toxins when tested – many of them with no toxicological roadmap.  The textile industry is the #1 industrial polluter of fresh water on the planet – the 9 trillion liters of water used annually in textile processing is usually expelled into our rivers without treatment and is a major source of groundwater pollution.  Now that virtual or “embedded” water tracking is becoming necessary in evaluating products, people are beginning to understand when we say it takes 500 gallons of water to make the fabric to cover one sofa.  We want people to become aware that when they buy anything, and fabric especially, they reinforce the manufacturing processes used to produce it.  Just Google “Greenpeace and the textile industry” to find out what Greenpeace is doing to make people aware of this issue.

Over 8,000 chemicals are used in textile processing, some so hazardous that OSHA requires textile scraps be handled as hazardous waste.   The final product is, by weight, about 23% synthetic chemicals – often the same chemicals that are outlawed in other products.  The following is by no means an all-inclusive list of these chemicals:

  • Alkylphenolethoxylates (APEOs), which are endocrine disruptors;
    • o Endocrine disruptors are a wide range of chemicals which interfere with the body’s endocrine system to produce adverse developmental, reproductive, neurological and immune effects in both humans and wildlife; exposure us suspected to be associated with altered reproductive function in both males and females, increased incidence of breast cancer, abnormal growth patterns and neurodevelopmental delays in children.(2)
  • Pentachlorophenols (PCP)
    • o Long-term exposure to low levels can cause damage to the liver, kidneys, blood, and nervous system. Studies in animals also suggest that the endocrine system and immune system can also be damaged following long-term exposure to low levels of pentachlorophenol. All of these effects get worse as the level of exposure increases.(3)
  • Toluene and other aromatic amines
    • carcinogens (4)
  • Dichloromethane (DCM)
    • Exposure leads to decreased motor activity, impaired memory and other neurobehavioral deficits; brain and liver cancer.(5)
  • Formaldehyde
    • The National Toxicology Program named formaldehyde as a known human carcinogen in its 12th Report on Carcinogens.(6)
  • Phthalates –
    • Associated with a range of effects from liver and kidney diseases to developmental and reproductive effects, reduced fetal weight.(7)
  • Polybrominated diphenyl ethers (PBDE’s)
    • A growing body of research in laboratory animals has linked PBDE exposure to an array of adverse health effects including thyroid hormone disruption, permanent learning and memory impairment, behavioral changes, hearing deficits, delayed puberty onset, decreased sperm count, fetal malformations and, possibly, cancer.(8)
  • Perfluorooctane sulfonates (PFOS)
    • To date, associations have been found between PFOS or PFOA levels in the general population and reduced female fertility and sperm quality, reduced birth weight, attention deficit hyperactivity disorder (ADHD), increased total and non-HDL (bad) cholesterol levels, and changes in thyroid hormone levels.(9)
  • Heavy metals – cadmium, lead, antimony, mercury among others
    • Lead is a neurotoxin (affects the brain and cognitive development) and affects the reproductive system; mercury is a neurotoxin and possibly carcinogenic; cadmium damages the kidneys, bones and the International Agency for Research on Cancer has classified it as a human carcinogen; exposure to antimony can cause reproductive disorders and chromosome damage.

The textile industry uses huge quantities of fossil fuels  –  both to create energy directly needed to power the mills, produce heat and steam, and power air conditioners, as well as indirectly to create the many chemicals used in production.  In addition, the textile industry has one of the lowest efficiencies in energy utilization because it is largely antiquated.  For example, steam used in the textile manufacturing process is often generated in inefficient and polluting coal-fired boilers.  Based on estimated annual global textile production of 60 billion kilograms (KG) of fabric, the estimated energy needed to produce that fabric boggles the mind:  1,074 billion KWh of electricity (or 132 million metric tons of coal).  It takes 3886 MJ of energy to produce 25 yards of nylon fabric (about the amount needed to cover one sofa).  To put that into perspective, 1 gallon of gasoline equals 131 MJ of energy; driving a Lamborghini from New York to Washington D.C. uses approximately 2266 MJ of energy.(10)

Today’s textile industry is also one of the largest sources of greenhouse gasses on the planet: in the USA alone, it accounts for 5% of the country’s CO2 production annually; China’s textile sector alone would rank as the 24th– largest country in the world.(11)

We succeeded in producing the world’s first collection of organic fabrics that were gorgeous and green – and safe.    In 2007, those fabrics won “Best Merchandise” at Decorex (www.decorex.com).    In 2008, our collection was named one of the Top Green Products of 2008 by BuiltGreen/Environmental Building News. As BuiltGreen/EBN takes no advertising dollars, their extensive research is prized by the green building industry (www.buildinggreen.com).

We are a tiny company with an oversized mission.  We are challenged to be a triple bottom line company, and we want to make an outsized difference through education for change  – so that a sufficiently large number of consumers will know which questions to ask that will force change in an industry.  We believe that a sufficiently large number of people will respond to our message to force profound positive change: by demanding safe fabric, produced safely, our environment and our health will be improved.

The issues that distinguish us from other fabric distributors, in addition to offering fabrics whose green pedigree is second to none:

    1. We manage each step of the production process from fiber to finished fabric, unlike other companies, which buy mill product and choose only the color palette of the production run.    Those production process steps include fiber preparation, spinning, weaving, dyeing, printing and finishing; with many sub-steps such as sizing and de-sizing, bleaching, slashing, etc.
    2. We educate consumers and designers on the issues that are important to them – and to all of us. Our blog on the topic of sustainability in the textile industry has grown from about 2 hits a day to 2,000, and is our largest source of new customers.
    3. We are completely transparent in all aspects of our production and products.    We want our brand to be known not only as the “the greenest”, but for honesty and authenticity in all claims.  This alignment between our values, our claims and our products fuels our passion for the business.
    4. We are the only collection we know of which sells only “safe” fabrics.

We serve multiple communities, but we see ourselves as being especially important to two communities:  those who work to produce our fabric and those who use it, especially children and their parents.

    • By insisting on the use of safe chemicals exclusively, we improve the working conditions for textile workers.  And by insisting on water treatment, we mitigate the effects of even benign chemicals on the environment – and the workers’ homes and agricultural land.  Even salt, used in copious amounts in textile processing, will ruin farmland and destroy local flora and fauna if not neutralized before being returned to the local waters.
    • For those who use our fabric, chemicals retained in the finished fibers do not add to our “body burden “, which is especially important for children, part of our second special community.  A finished fabric is, by weight, approximately 23% synthetic chemicals. Those chemicals are not benign.  Textile processing routinely uses chemicals with known toxic profiles such as lead, mercury, formaldehyde, arsenic and benzene – and many other chemicals, many of which have never been tested for safety.

Another thing we’d like you to know about this business is the increasing number of people who contact us who have been harmed by fabric (of all things!) because we represent what they believe is an honest attempt at throwing light on the subject of fabric processing.   Many are individuals who suffer from what is now being called “Idiopathic Environmental Intolerance” or IEI (formerly called Multiple Chemical Sensitivity), who are looking for safe fabrics.  We’ve also been contacted on behalf of groups, for example,   flight attendants, who were given new uniforms in 2011, which caused allergic reactions in a large number of union members.

These incidences of fabric-induced reactions are on the rise.   As we become more aware of the factors that influence our health, such as we’re seeing currently with increased awareness of the effects of interior air quality, designers and others will begin to see their way to specifying “safe” fabrics  just as their code of ethics demands.(12)  We feel certain that the trajectory for such an important consumer product as fabric, which surrounds us most of every hour of the day, will mimic that of organic food.

We say our fabrics are luxurious – because luxury has become more about your state of mind than the size of your wallet. These days, people define luxury by such things as a long lunch with old friends, the good health to run a 5K, or waking up in the morning and doing exactly what you want all day long.  In the past luxury was often about things.  Today, we think it’s not so much about having as it is about being knowledgeable about what you’re buying – knowing that you’re buying the best and that it’s also good for the world.  It’s also about responsibility: it just doesn’t feel OK to buy unnecessary things when people are starving and the world is becoming overheated.  It’s about products being defined by how they make you feel –  “conscious consumption” – and giving you ways to find personal meaning and satisfaction.

Our oceans and your textile choices

23 02 2011

I just don’t know what it takes to change people’s habits.  We need a huge wake up call about the disastrous state of our oceans!  Our oceans are our life support system.  And they’re in trouble.

Because this is a blog about textile issues, I wanted to remind you that  the textile industry is the world’s #1 industrial polluter of fresh water.    So remember that  each time you choose a fabric that has been processed conventionally, in a mill which does not treat its wastewater, you’re  adding to the problem.  We’re all downstream.  And please also remember that a fabric marked “organic cotton” – though decidedly better than conventional cotton – is still a fabric which is 27% synthetic chemicals by weight,  processed at a mill which returned the untreated, chemically infused effluent to our oceans.

Sorce: NOLA.com

People once assumed that the ocean was so large that all pollutants would be diluted and dispersed to safe levels. But in reality, they have not disappeared – and some toxic man-made chemicals have even become more concentrated as they have entered the food chain.

Tiny animals at the bottom of the food chain, such as plankton in the oceans, absorb the chemicals as they feed. Because they do not break down easily, the chemicals accumulate in these organisms, becoming much more concentrated in their bodies than in the surrounding water or soil. These organisms are eaten by small animals, and the concentration rises again. These animals are in turn eaten by larger animals, which can travel large distances with their even further increased chemical load.

Animals higher up the food chain, such as seals, can have contamination levels millions of times higher than the water in which they live. And polar bears, which feed on seals, can have contamination levels up to 3 billion times higher than their environment.

Some scientists describe the chemical change in the ocean as throwing evolution into reverse: the chemical composition is going back toward the “primordial soup,” favoring the simplest organisms – indeed, algae, bacteria and jellyfish are growing unchecked –  and threatening or eliminating the more complex.  There are so many jellyfish in the ocean that many fisheries have given up their normal catch and are just harvesting jellyfish.[1] Clickhere to view Jellyfish Gone Wild by the National Science Foundation.  In fact, according to a report published in the Los Angeles Times, these most primitive organisms are exploding:  it’s a ‘rise of slime’ as one scientist calls it.   It’s killing larger species and sickening people.

Los Angeles Times report  in 2006 (click here to read the entire article)  sounds like something from a horror movie:  A spongy weed, reported to grow at 100 square meters per minute – literally fast enough to cover a football field sized area in an hour – has been plaguing fishermen in Australia.  The culprit, it was found, is a strain of cyanobacteria known as Lyngbya majuscula, an ancestor of modern-day bacteria and algae that flourished 2.7 billion years ago.  It has since shown up in at least a dozen places around the globe. It thrives in oxygen depleted water.   Once established, Lyngbya creates its own nitrogen fertilizer from decaying parts of the plant.

Many fishermen in Moreton Bay avoid working in the four months every year that Lyngbya clogs their waters because it is highly toxic to them.  When fishermen touch it, their skin breaks out in searing welts.  Their lips blister and peel.   As the weed blanketed miles of Moreton Bay over the last decade, it stained fishing nets a dark purple and left them coated with a powdery residue. When fishermen tried to shake it off the webbing, their throats constricted and they gasped for air.

After one man bit a fishing line in two, his mouth and tongue swelled so badly that he couldn’t eat solid food for a week.

Scientists in labs studying the bacteria couldn’t even be in the same room with it, the smell was so pungent.  It’s like “The Blob” come to life.

Scientist Jeremy Jackson says that we have forgotten the basic rule of thumb:  “Be careful what you dump in the swimming pool, and make sure the filter is working.”

And to add insult to  our ocean’s injury, the number of dead zones – where there is so little oxygen only microbes can survive – has doubled every 10 years since the 1960s [2].  In 2008, there were 400 dead zones [3].   So does that make you worry?  It should.   This is an example of what mathematicians call “exponential growth”, and it’s the kind of thing that doesn’t really impact us until we’re about to be kicked in the teeth.

To demonstrate the concept, there is an old story about a king who was presented with a gorgeous handmade chessboard by one of his subjects.  The king was delighted, and asked what the man wanted in return.  The courtier surprised the king by asking for one grain of rice on the first square, two grains on the second, four grains on the third etc. The king readily agreed and asked for the rice to be brought.   But there was not enough rice in the world to fill the courtier’s request (see note below) – the total amount of rice required would be 18,446,744,073,709,551,615 grains of rice.   This is about  460 billion tons, or 6 times the entire weight of the Earth’s biomass.

And to see how the problem can become critical overnight (because according to the laws of exponential growth, the larger the quantity becomes, the faster it grows):  Imagine having a pond with water lily leaves floating on the surface. The lily population doubles in size every day and if left unchecked will smother the pond in 30 days, killing all the other living things in the water. We want to save the pond, so we check the lilies every day.   Yet day after day the plant seems small and so it is decided to leave it to grow until it half-covers the pond, before cutting it back. But the pond doesn’t becomes half covered until day 29 – leaving just one day to save the pond.  (4)

This concept has even led to the phrase “second half of the chessboard”, which refers to a point where an exponentially growing factor begins to have a significant impact.

So this news about the ocean dead zones – you might think that a dead zone the size of the state of Oregon is no big deal, but the area is growing exponentially.  How many years do we have until we reach the second half of the chessboard?

We must stop messing up our oceans.   If not for yourself, do it for your children. “You wouldn’t let a child open up a cabinet under the sink and start tasting the chemicals down there,” Fabien Cousteau says. “So why would you dump those chemicals down the drain and have them end up on your plate, which you then feed to your child?” (5)

NOTE regarding rice on the chessboard:

The total number of grains of rice on the first half of the chessboard is 1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 + 1024 … + 2,147,483,648, for a total of exactly 232 − 1 = 4,294,967,295 grains of rice, or about 100,000 kg of rice, with the mass of one grain of rice being roughly 25 mg.

The total number of grains of rice on the second half of the chessboard is 232 + 233 + 234 … + 263, for a total of 264 − 232 grains of rice. This is about 460 billion tonnes, or 6 times the entire weight of the Earth biomass.

On the 64th square of the chessboard there would be exactly 263 = 9,223,372,036,854,775,808 grains of rice. In total, on the entire chessboard there would be exactly 264 − 1 = 18,446,744,073,709,551,615 grains of rice.

How to define a “luxury” fabric

3 02 2011

from red-luxury.com

For hundreds of years, a “luxury”  item was something that was so well produced, so exclusive, and thus so expensive, that only the few – the elite – had access and the financial means  to buy it. Luxury was marketed to the rich as being a part of their social fabric, and to everyone else as being nothing more than an aspirational ideal.  In terms of fabrics, traditional luxury fibers (such as silk, cashmere, or Sea Island cotton) are today being given a run for the money by high tech fibers.

The most intriguing shift underway in our definition of luxury  may well be the changing nature of individual expectations. Luxury in the past was most often defined by things, and the value people place on those things. But increasingly, possession or association with “things” seems less important as an end than as a means to something else—how those things combine to help create a sense of self.

Luxury has become more about your state of mind than the size of your wallet, as people define luxury by such things as a long lunch, or the good health to run a 5K, or escaping into a book.  It means different things to different people  (think “luxury camping” –  some people can’t see the vaguest relationship between the two words) –   but any discussion about luxury is inevitably about time, one of the only things money can’t buy.  Dolce far niente. Waking up in the morning and doing exactly what you want all day.  Enjoying the pleasures of the moment.

Luxury today is also about responsibility: it just doesn’t feel o.k. to buy  things when people are starving and the world is becoming overheated.  And maybe, as we evolved to the point where a robust middle class means that we no longer have to work just to put food in our mouths, we have found that acquiring things doesn’t provide the transcendent experience we hoped it would.  We’re seeing a shift from mindless indulgence to, perhaps,  justified indulgence.    It’s about products being defined by how they make you feel – which is why we’re hearing about “conscious consumption”.  


How can we go to bed at night and sleep the dreamless sleep of the just when the sheets we’re sleeping on have been produced by slave labor, using a slew of toxic chemicals that affect both your own health and the ecosystem.   The same is true in the fashion industry – where sweatshops are still, unbelievably, common.  War on Want has a campaign to fight the sweatshops that still employ millions.

We think a “luxury” fabric is one with impeccable provenance: the best quality fibers were grown organically (or if a high tech synthetic, were produced using GOTS accepted chemicals in the dyeing and weaving); the manufacture was according to GOTS standards and the workers were paid a fair wage while working in safe conditions.

Luxury is still about buying the best quality – but today you must know why it’s the best –   and being knowledgeable  that what you’re buying is good for the world – or at least that it doesn’t compromise my life (or yours)  in the process.

The President’s Cancer Panel and fabric choices

6 10 2010

Ever wonder why you buy those organic foods that cost more?  It’s always a bit of sticker shock when you see the organic and conventional side by side.   The organic strawberries may taste better, but this economy means we have to pinch every penny.  As my husband says, an apple is an apple, so why pay more for one when you can get the other cheaper?  It’s not going to do anything to me – at least not today.

Turns out you might want to re-think those – and lots of other –  choices you make every day.  The President’s Cancer Panel issued a 240-page report in May, 2010, called “Reducing Environmental Cancer Risk: What We Can Do Now” This year’s report is the first time the panel has emphasized the environmental causes of cancer. It warns of “grievous harm” from chemicals and other hazards, and “a growing body of evidence linking environmental exposures to cancer.” Children are especially vulnerable.

The report is based on testimony from a series of meetings held between September 08 and January 09 which  included 45 invited experts from academia, government, industry, the environmental and cancer advocacy communities, and the public. The report urged President Obama to “use the power of your office to remove the carcinogens and other toxins from our food, water, and air that needlessly increase health care costs, cripple our nation’s productivity, and devastate American lives.”  Because industrial chemicals are so ubiquitous and exposure to these potential environmental carcinogens so widespread, “the Panel was particularly concerned to find that the true burden of environmentally induced cancers has been grossly underestimated,”

The report said previous estimates that environmental pollutants and occupational exposures cause 6% of all cancers are low and “woefully out of date.”  In fact, the National Institutes of Health estimates that environmental factors contribute to 75-80% of all cancers: from tobacco smoke, ultraviolet light, radiation, obesity and certain viruses and sexually-transmitted diseases – in addition to environmental carcinogens. One excerpt reads, “With nearly 80,000 chemicals on the market. … many of which are used by millions of Americans in their daily lives and are. … largely unregulated, exposure to potential environmental carcinogens is widespread.”

The President’s Panel report clearly states that much work has to be done to better characterize environmental determinants of cancer—including better research methods, standardized measurements, and more realistic models that can help estimate the cumulative risks associated with multiple environmental toxins.  But scientists have been scrambling for decades for scarce funding  – and the work was given a low priority.  The fundamental problem is that research into environmental causes of cancer has little potential for yielding profits—at least in the short-term. In fact, it is more likely to cost industry through stronger regulation and removal of products from the market, litigation and the added expense of developing new products based on “green chemistry.” So it’s not a stretch to understand why the government and the pharmaceutical industry would rather spend billions of dollars promoting screening and developing profitable new cancer drugs.  Peter Montague, a long-time environmental advocate puts it this way: “To be blunt about it, there’s no money in prevention, and once you’ve got cancer you’ll pay anything to try to stay alive.”

Environmental toxins are rarely considered in health policy initiatives (except for tobacco and sunlight), despite the findings that people who live in polluted areas and work with toxic substances (most often the poor and minorities) have higher rates of cancer incidence.  The Cancer Panel  pointed out  “Cancer Alley“, the stretch along the Mississippi between Baton Rouge and New Orleans, as an example.  Louisiana ranked second in the nation for on-site toxic releases, and many studies exist which demonstrate the cancer rate is above the average for the rest of the United States.  In one small Louisiana town in Cancer Alley, 3 cases of rhabdomyosarcoma were reported in a 14 month period.  Rhabdomyosarcoma is an extremely rare and devastating childhood cancer, with a national average of one child in a million.  Five years ago a group of residents of Mossville, Louisiana, filed a human rights complaint against the US government, alleging it was not protecting their right to live in a healthy environment.  The Inter-American Commission on Human Rights agreed this year to hear their complaint.

In a consensus statement,  the Collaborative on Health and the Environment, an international partnership of some 3,000 individuals and organizations, says that the net result of this inadequate funding is a body of research that is in danger of being irrelevant:

“The methods that have been used to attribute cancer risk to environmental exposures are outdated and flawed, and should no longer be used to determine policy or set research priorities.”

So it’s not just organic foods that we should be concerned about, but the whole phalanx of products which are made using harmful chemistry, and the manufacturers that don’t capture emissions or treat their waste products, thereby polluting our entire ecosystem.  That’s why O Ecotextiles has made a commitment to sell only fabrics which are safe for both you and the Earth.

I found it interesting that there is a new branch of science that is also studying how these environmental factors can influence us.  Called epigenetics, it is the study of changes in gene activity that don’t involve changes to the genetic code but still get passed down to at least one successive generation.   These patterns of gene expression are governed by the cellular material — the epigenome — that sits on top of the genome, just outside it (hence the prefix epi-, which means above). It is these epigenetic “marks” that tell your genes to switch on or off, to speak loudly or whisper. It is through epigenetic marks that environmental factors like diet, stress and prenatal nutrition can make an imprint on genes that is passed from one generation to the next.

One could think of the genome as a book of blueprints,  laying out a number of options in the form of genes. The epigenome is like the contractor who goes through the book, deciding which options to include in a house. Two different contractors can build radically different houses from the same book of blueprints, in the same way that two organisms with identical DNA can look very different.

This field of study, some believe, might hold the key to understanding how environmental toxins cause serious, and often life-threatening diseases, such as obesity, diabetes and cancer.  For quite some time scientists have been trying to determine how exposure to environmental toxins can result in serious disease years or even decades later. Epigenetics may provide the mechanism. An exposure to an environmental toxin at one point in a person’s life (and most critically during gestation) can trigger the epigenome to turn on or turn off a key gene. Years later, because of that epigenetic change, a disease may appear.

“We can no longer argue whether genes or environment has a greater impact on our health and development, because both are inextricably linked,” said Randy Jirtle,  Ph.D., a genetics researcher in Duke’s Department of Radiation Oncology. “Each nutrient, each interaction, each experience can manifest itself through biochemical changes that ultimately dictate gene expression, whether at birth or 40 years down the road.”

Exposures to pesticides, toxins and synthetic compounds can give rise to a host of diseases – such as cancer and asthma — whose prevalence has soared in recent decades, says H. Kim Lyerly, M.D., director of the Duke Comprehensive Cancer Center.  Pesticides encountered in utero might be dormant in the fetus, only to cause cancer ten, 20 or 50 years later, he said.

Even the lowest detectable limits of a chemical can have dire effects on a living organism, added William Schlesinger, Ph.D., Dean of the Nicholas School of the Environment and Earth Sciences at Duke. Atrizine is a prime example. Less than one part per billion of this widely used corn herbicide de-masculinizes developing frogs or causes dual male-female genitalia. Yet often the Environmental Protection Agency’s instrumentation doesn’t record such minute levels of chemical exposure, he said.

What does the Cancer Panel suggest we do in the meantime?  Here is their list, with a few of additions of our own:

  • Remove your shoes before entering your home to avoid tracking in toxic chemicals such as pesticides.
  • Filter tap water.
  • Use stainless steel, glass or BPA-free plastic water bottles.
  • Microwave in ceramic or glass instead of plastic containers.
  • Become aware of what you’re eating:  minimize consumption of food grown with pesticides, and meat raised with antibiotics and growth hormone.
  • Minimize consumption of processed, charred or well-done meats, which contain carcinogenic heterocyclic amines and polyaromatic hydrocarbons.
  • Reduce radiation from X-rays and other medical sources.
  • Be aware of the products you use, especially those that come in contact with your skin, such as:  lotions, cosmetics, wipes, sheets, clothing, hair dyes.  Check ingredient labels, look for third party certifications where appropriate.
  • And finally:  use sunscreen, stop smoking and lose weight if necessary.
