TOXIC CHEMICALS: Big Agriculture and big coal are big polluters, and their policies are having a big impact on our environment and health

Big Ag is a big polluter

Industrial agriculture has the ability to supply large amounts of food on the cheap. However, cheap food comes with consequences. For starters, the process is resource and energy intensive, and it leaves behind a footprint on the environment and our health. For example, pesticides applied to fruit orchards and vegetable fields leach from the area of application into the landscape, negatively impacting ecosystems. These chemicals also remain as residue on fruits and vegetables. Consequently, in addition to getting the recommended daily servings of fruits and vegetables (and depending on our choices, which are based on how cognizant we are of where our food originates) we might be ingesting herbicides and pesticides on a daily basis. Consequently, sometimes it’s better to buy organic (i.e., “because ‘organic’ can mean ‘pricey,’ it makes sense to focus on buying organic versions of produce that is most likely to harbor pesticide residues when grown conventionally“).

Toxic chemicals leach into foods via the plastic lining of metal cans

Some “canned foods, including soups, juice, tuna, and green beans” have been found to “contain measurable levels of Bisphenol A (BPA).” BPA has also been found in baby bottles and baby food, and research has linked the chemical to a multitude of health problems. However, it’s possible to avoid plastics containing BPA:

BPA is found in polycarbonate plastic food containers often marked on the bottom with the letters “PC” recycling label #7. Not all #7 labeled products are polycarbonate but this is a reasonable guideline for a category of plastics to avoid. Polycarbonate plastics are rigid and transparent and used for sippy cups, baby bottles, food storage, and water bottles. Some polycarbonate water bottles are marketed as ‘non-leaching’ for minimizing plastic taste or odor, however there is still a possibility that trace amounts of BPA will migrate from these containers, particularly if used to heat liquids.

Safer products and uses: When possible it is best to avoid #7 plastics, especially for children’s food. Plastics with the recycling labels #1, #2 and #4 on the bottom are safer choices and do not contain BPA. Find baby bottles in glass versions, or those made from the safer plastics including polyamine, polypropylene and polyethylene. Soft or cloudy-colored plastic does not contain BPA. Bottles used to pump and store expressed breast milk by the brand Medela are also labeled BPA-free.

In addition to a wide range of health problems, research suggests that BPA impacts human reproduction. From Nature.com:

paper in the journal Human Reproduction adds weight to a long-held (by some) suspicion that the plasticising chemical bisphenol A (BPA) does bad things to the body’s hormone balance.

In this study, male workers in Chinese factories handling BPA were compared to a control group of Chinese factory workers who weren’t exposed to BPA over five years.

The results showed that the workers in the factories handling BPA had four times the risk of erectile dysfunction, and seven times more risk of ejaculation difficulty (press release).

This stark conclusion is the first direct evidence that exposure to BPA in the workplace could have bad health effects, the authors led by De-Kun Li, a reproductive and perinatal epidemiologist at Kaiser Permanente’s Division of Research in Oakland, California.

For years BPA has been associated with a range of health problems, from cancer to diabetes and heart disease.

The suspicion was that BPA was an endocrine disruptor – a substance that mucks up the way hormones in the body, including sexual reproduction hormones – are made and regulated. This study, the authors say, provides the evidence that the US regulators have been after for years. They add that the levels in this study were very high – nothing like the levels people are normally exposed to in everyday life.

The chemical is already regulated. In Canada, for example, BPA is banned in baby bottle manufacture, and in France earlier this year members of the senate sought a ban on BPA. Of course, there is also perhaps a need for caution – don’t be terrified, not all plastics used in baby products or drinks bottles contain BPA, and no links between low exposure levels and adverse health effects have been found. In the US at least, it seems that it is easy to check whether BPA is present: there should be a number 7 printed on any bottle that contains the stuff.

Big Coal emits a deadly neurotoxin that accumulates within the environment

Invisible toxins are emitted through energy production when fossil fuels such as coal are burned. For example, when coal is burned, mercury—a neurotoxin—is released “into the environment, [and] coal-burning power plants are the largest human-caused source of mercury emissions to the air in the United States, accounting for over 40 percent of all domestic human-caused mercury emissions.” Mercury is converted by natural processes into methylmercury, which accumulates in the food chain. Consequently, our food becomes contaminated with a nerotoxin, which can make people sick.

A toxic soup

There’s no doubt that chemicals and toxins from agriculture, burning fossil fuels, and other industrial processes are negatively impacting our bodies and minds and even resulting in death by triggering diseases such as cancer. “Toxic Soup,” a documentary, “connects the current spikes in childhood cancer, autism, and other serious illnesses with the business practices of Fortune 500 companies: DuPont, Bayer, Ashland Oil, and Massey Energy.” More on the documentary:

‘Toxic Soup’ is a look at the lives of everyday Americans who discover pollution in their backyards and decide to fight for the clean air, water & blood that we all deserve. And it’s David versus Goliath as this enviro documentary follows a team of investigators who explore three industries critical to the growth of US superpower. Coal gave us electricity; Oil gave us the automobile; And chemistry everything in between. But at what price

The trailer for “Toxic Soup”:

To illustrate the stealthy toxic soup we’re exposed to via industrial practices, one study tested the blood and urine of pregnant mothers, and the “study reveal[ed] that children spend their first nine months in an environment that exposes them to known toxic chemicals.” More from Consumer Affairs:

In the WTC study, researchers tested pregnant women from Washington, California, and Oregon and discovered:

• Every woman was exposed to BPA, the hormone disrupting chemical used to make polycarbonate plastic and the lining for food cans. BPA is linked to cancer, early puberty, diabetes, obesity, and reproductive problems, researchers said;

• Each woman had at least two and as many as four “Teflon chemicals,” or perfluorinated compounds, in her blood. Those chemicals are used to create stain-protection products and non-stick cookware and are linked to low birth weight, obesity, and cancer, the groups said.

• Every woman had mercury in her blood. Mercury is known to harm brain development, researchers said. The National Academy of Sciences has also reported that 60,000 children each year may suffer brain problems as a result of exposure to mercury in the womb. This exposure can affect their ability to play and learn.

• Every woman was exposed to at least four phthalates, the plasticizers and fragrance carriers found in shower curtains, shampoo, soaps and other consumer products. Phthalates are linked to reproductive problems and asthma.

The findings shocked and angered women in the study.

There are alternatives to industrial agriculture, fossil fuels, and toxic chemicals such as (1) permaculture or other (2) sustainable farming methods, (3) renewable energy and energy conservation, (4) decentralized energy production, and (5) green chemistry.

AGRICULTURE: Harvard professor raises awareness about small-scale back yard agriculture and tradition by grazing cow in Harvard yard

The ability to raise livestock in our back yards or urban environments may be restricted by local municipal regulations. However, smaller landowners, even in urban environments, can turn small spaces into useful and productive environments. Some examples of small back yard agriculture include: (1) growing vegetables and herbs in container gardens or buckets; (2) constructing small intensive raised-bed gardens; (3) raising chickens in urban environments (see urbanchickens.org too); (4) keeping urban beehives (people living in urban environments have been encouraged to keep bees); and (5) there are many other examples of urban agriculture as well. More from the Harvard University Gazette (emphasis added):

“I’d always heard the stories of the traditions of cows grazing in the Yard and really couldn’t pass up the opportunity to see one,” said Radcliffe alumna Naomi Shore. “I think it’s great fun.”

The response was just what Cox was hoping for. While the ceremony provided a lighthearted break from the pressures and pace of the early back-to-school frenzy, it also offered something a little more concrete, remarked the professor.

The cow’s presence, Cox told the crowd, represents “how much closer we need to be to the animals that sustain us, to the Earth, the grass, the vegetables. … Perhaps it shouldn’t be such an oddity to see a cow grazing in Harvard Yard. If it happened once, perhaps it could happen again. And if not a cow, [or] a pasture, perhaps then at least a garden,” he said, adding that if the White House lawn could have a garden Harvard Yard surely could.

AGRICULTURE: Mini moos are en vogue

Miniature CattleMiniature cattle are popular because of their small size, ability to provide high-quality tender meat, and raw milk fans use these miniature cattle for home milk production.

Learn more about miniture cattle breeds at the International Miniature Cattle Breeds Registry, INC. More from Macleans.ca:

Richard Gradwohl, of the International Miniature Cattle Breeds Society and Registry, in Covington, Wash. has seen a 25 per cent increase worldwide in miniature cattle year over year during the past 15 years. Despite its big-sky, red-meat reputation, Alberta is the centre of the movement in Canada, with perhaps half of the country’s Dexter population and the first restaurant to serve exclusively Dexter beef—Apples, in Bashaw, an hour and a half northeast of Red Deer.

Mini-cow breeds weigh between 500 and 700 pounds, about half the size of regular breeds, and are either bred down from Hereford, Holstein, Jersey or Angus lines or, like the dual-purpose Dexter breed—good for both milk and beef—are naturally tiny.

A recent explosion in small hobby farms catering to niche markets helped boost their appeal even prior to the economic downturn, as did growing concern over food safety, sustainability and the environmental footprint of beef. Fans of raw milk are more and more turning to mini-cows to produce their own; the efficiency can be startling: a Holstein-Jersey miniature cross will eat a third of what a larger dairy cow will but produce two-thirds the milk. In the U.S., mini-cows are more and more popular as pets, particularly among women.

Enthusiasts, meanwhile, extol the excellent quality of the meat, which is said to be more tender. “They taste like good beef,” says Hykaway, a retired electrician who has 45 head at Tandria Dexters, just east of Fort Saskatchewan. “Because a lot of us aren’t using grain, they have that nice distinct grass taste.”

WATER POLLUTION: Agricultural, industrial, and suburban runoff threatens nation’s water supply—pollution impacting our health and the environment—nation’s dwindling water quality highlighted in new documentary

Poisoned Waters is a documentary by Frontline that investigates and reveals how certain human activity in the United States (and certainly all over the world) is impacting our water supply and the environment, resulting in amphibian deformities, intersex fish, and decreased sperm counts amongst other problems. Naturally, these negative impacts to the environment translate into our health as well.

From PBS.org:

More than three decades after the Clean Water Act, two iconic waterways—the great coastal estuaries Puget Sound and the Chesapeake Bay—are in perilous condition. With polluted runoff still flowing in from industry, agriculture, and massive suburban development, scientists fear contamination to the food chain and drinking water for millions of people. A growing list of endangered species is also threatened in both estuaries. As a new president, Congress, and states set new agendas and spending priorities, FRONTLINE correspondent Hedrick Smith examines the rising hazards to human health and the ecosystem, and why it’s so hard to keep our waters clean.

AGRICULTURE: Are free-range chickens healthier than caged chickens?

free-range-chickensA case study from Sweden: In an effort to improve chicken farming, Sweden banned “the use of small laying cages and instead [required] that chickens live more naturally — with access to nests, perches, and piles of dust they can roll around in.” However, some problems developed, which seemed to be triggered by the new policies, such as bacterial, parasitic, and viral infections, in addition to “pecking and cannibalistic attacks.” No doubt, the number of chickens being housed, in addition to the breed of chicken being used are factors that should be considered—especially since some farmers will try and maximize their profits.
