And in an industrial world where the animals are increasingly seen as a commodity or product to make money on haven’t improved the animals well-being. Rather, the intensification of our agriculture sector has made their life worse. And this cruelty is happening around the world. Even in the Swedish meat industry animal cruelty is common. And this even though the Swedish meat industry often and proudly proclaims itself for having "the world’s best animal welfare", one can see the awful consequences of industrial farming. The latest example of this is the Animal Rights Alliance disclosure earlier last year on the abuse and neglect of Swedish pigs.

The following disturbing photos in this blog post has all been provided by the animal rights organization Farm Sanctuary. The organization, which is based in New York, was founded in 1986. Farm Sanctuary document the abuses of factory farms, slaughterhouses, and stockyards, rescue animals from these conditions, rehabilitating and caring for animals at shelters in New York and California, as well as running advocacy and education campaigns on these issues.

Confined in metal and concrete pens with slatted floors, these pigs will live in these conditions until they reach slaughter weight of 250 pounds.

Female pigs used for breeding (breeding sows) spend most of their lives confined in gestation crates so narrow that they cannot turn around.

As you can see, a female pig in a gestation crate has no freedom of movement, and barely even has room to lay down.

Most beef cattle spend the last few months of their lives at feedlots, crowded by the thousands into dusty, manure-laden holding pens. The air is thick with harmful bacteria and particulate matter, and the animals are at a constant risk for respiratory disease. Feedlot cattle are routinely implanted with growth-promoting hormones, and they are fed unnaturally rich diets designed to fatten them quickly and profitably. Because cattle are biologically suited to eat a grass-based, high fiber diet, their concentrated feedlot rations contribute to metabolic disorders.

To raise calves destined to be slaughtered for veal, the calves are confined in crates about two feet wide and are tethered to the front of the crate with a chain around the neck. These calves will be slaughtered when 4-5 months old.

Dairy cattle make up the largest percentage of downed animals in factory farming, 75%. Too sick or injured to walk, this dairy cow is left in the stockyard while a calf looks on.

Though there have been moves in Europe to phase out battery cages for hens, in the US the vast majority of egg laying chickens are confined in battery cages such as these. These cages have wire floors and four or five hens are commonly packed into each cage. Obviously they cannot stretch their wings or exhibit any normal chicken behavior.

At chicken hatcheries, chicks enter the factory farming world packed into huge drawers.

Behind a hatchery for laying hens, unwanted male chicks–which are of no economic value to the egg industry–are simply tossed into a dumpster with shells and other waste.

Because commercial turkeys have been bred to have such unnaturally large breasts, to satisfy consumer preference for breast meat, they cannot mount and reproduce naturally. Thus, artificial insemination must be used for reproduction.

Due to the severely overcrowded conditions they will face, baby turkeys have the upper part of their beaks seared off so that injuries caused by pecking one another can be minimized.

Although not confined in cages like egg laying chickens, chickens raised for meat are packed so tightly in grower houses that each chicken is alloted about half a square foot of space. If that isn’t bad enough, because broiler chickens have been bred to grow so quickly (twice as fast and large as their ancestors) the organs and skeleton don’t always keep up with this growth. The heart and lungs can’t support the unnatural body mass, resulting in heart failure and large numbers of deaths a year due to health conditions.

Up to 10,000 chickens are often packed into cages for shipping to the slaughterhouse. On route, they are offered no protection from the elements and a certain percentage of birds are expected to die on each journey due to cold or heat.

At the slaughterhouse, chickens are hung up by their feet fully conscious. Although some slaughterhouses stun the birds by passing them through an electrified bath of water, US federal law specifically excludes chickens from the Humane Slaughter Act mandating that animals be stunned before being killed. However, often times the birds are not rendered unconscious by the shock and proceed, still hung by their feet, to have their necks cut by a mechanical blade. Unfortunately if the bird is not sufficiently stunned, the blade may not actually kill it and the animal proceeds to the next stage in the process while still alive. The birds are then submerged in boiling water to scald them and remove feathers. It’s estimated that millions of chickens a year in the US are ultimately killed in the slaughterhouse by this last step, being boiled alive.

At this point, most people are at least somewhat aware that pesticides cause a great deal of environmental harm. Less well known are the effects pesticides have on individual and public health. Here, I give you 5 compelling reasons to avoid pesticides.

A quick note: This list is a little data-heavy.  To start, it will help to read through the bold lines first, and then go back to see the data behind each claim.

1. Acute exposure can kill you.

“Late in the afternoon of April 1, 1990, a three-year-old girl playing in front of her trailer home in California’s San Joaquin Valley suddenly lost control of her body and began foaming at the mouth. By the time the girl arrived at the local emergency room, she was near death. She recovered eventually. A report filed with the California Department of Pesticide Regulation concluded the child had been poisoned by aldicarb, a highly toxic insecticide that works the same way on people as it does on bugs — like nerve gas. ‘Somebody had parked a tractor with pesticide material on it right in front of the play area,’ said Michael O’Malley, the author of the report and a physician at the University of California, Davis.”
– Matt Crenson, Associated Press, December 9, 1997

Some common symptoms of over-exposure include burning, stinging, or itchy eyes, nose, throat and skin; nausea, vomiting, diarrhea, wheezing, coughing, headache. These symptoms can range from mild irritation to death. These symptoms are often misdiagnosed and not attributed to pesticide poisoning. [Peel Public Health]

2. Chronic exposure to pesticides can lead to neurological damage, including Parkinson’s and Alzheimer’s disease.

Several studies have shown a link between pesticide exposure and the onset of Parkinson’s disease, Alzheimer’s disease, as well as other neurological conditions such as epilepsy. The main path of exposure is airborne: breathing pesticides. Recently, UCLA researchers looked at Central Valley residents diagnosed with Parkinson’s disease, and found that “years of exposure to the combination of these two pesticides [the herbicide paraquat and fungicide maneb] increased the risk of Parkinson’s by 75 percent. Further, for people 60 years old or younger diagnosed with Parkinson’s, earlier exposure had increased their risk for the disease by as much as four- to six-fold.” [ScienceDaily]

Dr. Patrick Carr of the University of North Dakota finds that low doses of pesticide exposure induces physical changes in the brain, shown in a PET scan. These changes correlate to “a loss of neurons in particular regions of the brain.” Other regions not experiencing a loss instead express different amounts of neurotransmitter chemicals, altering the delicate chemical balance in the brain.

3. Chronic exposure to pesticides increases the chance of developing endocrine and reproductive disorders. Here are two pesticides to use as case studies:

DDT:
Young women exposed to DDT (in the 1950s) have a greater chance of developing breast cancer later in life. From the Pesticide Action Network – UK:

One recent study found higher levels of miscarriages among women exposed to DDT, and reproductive disorders associated with DDT are well documented in animal studies[6,7]. Another recent study found developmental delays among babies and toddlers exposed in the womb[8]. Other studies have linked DDT to reduced breastmilk production, premature delivery and reduced infant birthweights[9,10]. DDT is classified by US and international authorities as a probable human carcinogen[11].

DDT is now banned in the US, but is being revived for use as an anti-malaria agent in developing nations. I mention DDT because it shows you the egregious effects of using pesticides that have been poorly studied. Additionally, DDT is still present in our air.

Atrazine:
Atrazine has been one of the top two selling pesticides in the US, also commonly found in household pesticide sprays. Many studies on frogs and rodents have shown that atrazine causes developmental disorders and delays and compromises healthy immune function. Most significantly, atrazine causes male frogs and rodents to feminize and produce ovaries and eggs. Animal studies have predictive value in humans, as hormone functions are very similar among all animals. Tyrone Hayes, professor of Integrative Biology at UC Berkeley (whose course I took, he is absolutely amazing, by the way), has done extensive work on this subject and is a prime example of science activism. His website, atrazinelovers.com informs the public about all deleterious effects of atrazine and is backed up with extensive research data. His site states,

similar to atrazine’s induction of prostate cancer and mammary cancer in laboratory rodents, men exposed to atrazine in a Syngenta production facility in Louisiana developed prostate cancer at 8.4 times the rate of unexposed factory workers [9, 10] and women whose well water was contaminated with atrazine were more likely to develop breast cancer when compared to women who lived in the same area, but who do not drink well water [11].

4. Pesticide spray can drift through the air, being carried thousands of miles from where it was originally sprayed. They contaminate our waterways, and can be found in drinking water.

Pesticides can be detected miles from agricultural sites, can be detected in rainfall, as well as in the air. A study by the US Geological Survey in 2000 revealed that “every rain and air sample collected from the urban and agricultural sites had detectable levels of multiple pesticides. The magnitude of total concentration was 5-10 times higher at the agricultural site as compared to the urban site.” In this study, methyl parathion was the pesticide with highest concentration in both air and rain samples. Additionally, even though two decades have passed since the ban of DDT in the US, a metabolite of DDT (p,p’-DDE) was detected in every air sample collected from the agricultural site and in over half the air samples from the urban site.

Atrazine:
Atrazine is highly mobile and can travel as far as 600 miles from the initial point of application. Every year, a half million pounds of atrazine returns to the US in the form of rain and snowfall. It is also the most common groundwater contaminant, and has persisted in France where it has not been applied for 15 years. [atrazinelovers.com]

The EPA allows an average of 3 ppb (parts per billion) of atrazine to be present in drinking water. This is a running average, and does not consider the maximum level that could possibly be present during peak use of atrazine. “Concentrations as low as 0.1 ppb have been shown to alter the development of sex characteristics in male frogs.” [NRDC]

5. Persistent pesticide use over long periods of time results in lower crop yields, reduced soil fertility, and increased susceptibility to attack by new forms of pests and disease.

Soil fertility and crop yield:
Pesticides reduce activity of beneficial microflora in soil, therefore while yields are initially high, they will decline over time due to loss of soil health and fertility. I will have to save discussion of beneficial microflora in soil for a different entry, but in essence, soil health depends on a large variety of factors. These include a combination of beneficial bacteria (rhizobia), fungi (mycelia), worms, etc, working together to aid plants in nutrient absorption. A study by Tulane University Professor John McLachlan reveals the inhibitory effects pesticides have on these beneficial microflora and fauna, and how this translates to declining yields over time, as well as declining soil health (the ability to continue to grow crops).

Genetic diversity for resistance to pest and disease outbreak:
Industrial agriculture also promotes growing crops in monoculture, which means to grow only one species of crop, eliminating any genetic diversity. Genetic diversity is an asset which protects against new diseases. Pests, viruses, and bacteria are all constantly mutating. If an invading pest arrives with a powerful new mutation, a monoculture cannot withstand the pest attack. However, a genetically diverse set of crops will have a greater chance of withstanding the attack, as some variations may have better protection against new intruders than others. Don’t put your eggs in one basket! Such extensive pesticide use increases a monoculture crop’s vulnerability to disease and also accelerates pesticide resistance in weeds. [PANNA]

To end on an optimistic note: The amount of detectable pesticide residues in human urine drops immediately after switching to an organic diet. [Chengsheng Lu et. al]

We all know that the meat industry is a dangerous threat to our climate and overall a questionable industry. The cattle release CO2, methane and other greenhouse gases. They also use a lot of land areas, around 25% of the earths total land area. And about one third of all farm areas are used to grow food for the cattle.

According to studies the meat industry is responsible for about one fifth of all greenhouse gas emissions, in the world. That means they currently pollutes more than the whole transport sector. And by year 2050 the meat production is expected to increase with 50%.

And then I haven’t even mentioned the rather obvious animal suffering.

But maybe, if some “environmentally concerned scientists” get their way, the meat you’ll eat in the future will be produced inside a lab. Scientists from the In Vitro Meat Consortium are currently trying to produce meat from muscle tissue for human consumption.

This laboratory-grown meat, or in vitro meat, should not be confused with “imitation meat”, which often is produced from soy or gluten. The in vitro meat will be actual animal flesh, but flesh that never has been part of a living animal.

The in vitro meat would, according to the In Vitro Meat Consortium, be healthier and contain fewer diseases. It would also reduce animal suffering and have positive effect on the environment.

But some people are concerned that the in vitro meat will be of lesser quality and contain unresolved health risks than ordinary meat. Others worries that the in vitro meat will be different in appearance, taste, smell and even texture and thus reduce its appeal for consumers.

Either way the in vitro meat is far from the market today. More research needs to be done and there are currently several obstacles that need to be solved first:

• Proliferation of muscle cells: Although it is not very difficult to make stem cells divide, for meat production it is necessary that they divide at a quick pace. This requirement has some overlap with the medical branch of tissue engineering.
• Culture medium: Proliferating cells need a food source to grow and develop. The growth medium should be a well-balanced mixture of ingredients and growth factors. Depending on the motives of the researchers, the growth medium has additional requirements.
  • Commercial: The growth medium should be cheap to produce.
  • Environmental: The production of the growth medium shouldn’t have a negative impact on the environment. This means that the production should be energetically favorable. Additionally, the ingredients should come from completely renewable sources. Minerals from mined sources are in this case not possible, as are synthetically produced nutrients which use non-renewable sources.
  • Animal welfare: The growth medium should be devoid of animal sources, although they may initially be more useful than other sources.
  • Space travel: The growth medium should be almost completely created from the waste products in the space ship, if it is to be used in space travel.
• Bioreactors: Nutrients and oxygen need to be delivered close to each growing cell, on the scale of millimeters. In animals this job is handled by blood vessels. A bioreactor should emulate this function in an efficient manner. The usual approach is the creation of a sponge-like matrix in which the cells can grow, and perfusing it with the growth medium.

From Wikipedia.

Although more research needs to be done there is progress in this area, especially in Europe.

M. A. Benjaminson from Touro College performed the first, actual, research about in vitro meat. Benjaminson managed to grow muscle tissue from a goldfish in a laboratory setting.

And in 2004 researchers from Europe formed the non-profit organization New Harvest. According to them laboratory-grown meat in a processed form, like sausages and hamburgers, “may become commercially available within several years”.

In April 2005 the Dutch government granted a two million euro subsidy for a laboratory-grown meat project by Henk Haagsman at the University of Amsterdam.

At a workshop held at the Norwegian University of Life Sciences on June 15, 2007 the In Vitro Meat Consortium was established with the goal “to facilitate the establishment of a large-scale process industry for the production of muscle tissue for human consumption through concerted R&D efforts and attraction of funding to fuel these efforts.”
