wells and divining rods

Economist magazine has an article in its April 11 - 17 issue titled Sin Aqua Non. Their take on the international water situation is that the world has enough water, but we're wasting so much of it that we're creating water shortages.

How are we wasting it? Well - one primary way is by eating too much meat.

--------

Two global trends have added to the pressure on water. Both are likely to accelerate over coming decades.

The first is demography. Over the past 50 years, as the world’s population rose from 3 billion to 6.5 billion, water use roughly trebled. On current estimates, the population is likely to rise by a further 2 billion by 2025 and by 3 billion by 2050. Demand for water will rise accordingly.

Or rather, by more. Possibly a lot more. It is not the absolute number of people that makes the biggest difference to water use but changing habits and diet. Diet matters more than any single factor because agriculture is the modern Agasthya, the mythical Indian giant who drank the seas dry. Farmers use about three-quarters of the world’s water; industry uses less than a fifth and domestic or municipal use accounts for a mere tenth.

Different foods require radically different amounts of water. To grow a kilogram of wheat requires around 1,000 litres. But it takes as much as 15,000 litres of water to produce a kilo of beef. The meaty diet of Americans and Europeans requires around 5,000 litres of water a day to produce. The vegetarian diets of Africa and Asia use about 2,000 litres a day (for comparison, Westerners use just 100-250 litres a day in drinking and washing).

So the shift from vegetarian diets to meaty ones—which contributed to the food-price rise of 2007-08—has big implications for water, too. In 1985 Chinese people ate, on average, 20kg of meat; this year, they will eat around 50kg. This difference translates into 390km3 (1km3 is 1 trillion litres) of water—almost as much as total water use in Europe.

The shift of diet will be impossible to reverse since it is a product of rising wealth and urbanisation. In general, “water intensity” in food increases fastest as people begin to climb out of poverty, because that is when they start eating more meat. So if living standards in the poorest countries start to rise again, water use is likely to soar.

Moreover, almost all the 2 billion people who will be added to the world’s population between now and 2030 are going to be third-world city dwellers—and city people use more water than rural folk. The Food and Agriculture Organisation reckons that, without changes in efficiency, the world will need as much as 60% more water for agriculture to feed those 2 billion extra mouths. That is roughly 1,500km3 of the stuff—as much as is currently used for all purposes in the world outside Asia.

zucchini bread!

Perhaps because vegans are geniuses, AND because great (or "genius") minds tend to think alike, Andie over at Newbie Vegetarian and I are both writing about Zucchini Bread at the moment.

IMG_0251

Along with a poor man's bean salad (that I found somewhere on the internet), Zucchini Bread is one of the few staple dishes that I make. It can serve as either a dessert, or, because it is so filling, a full-on meal.

My wife found this recipe in a book called Breaking the food seduction which was written by the guy behind the Physicians Committee for Responsible Medicine. I like these guys (and agree with them that meat is basically unhealthy), but you have to understand that they are the medical version of PETA. They once tried to have hot dogs and processed meats banned from U.S. schools because of the well proven links between these meats and problems like cancer.

IMG_0254

Anyway - the zucchini bread is pretty simple to make. Basically you put all the dry ingredients together in one bowl, mix all the wet ingredients together in another bowl, and then combine them and bake.

IMG_0255

2 cups whole wheat flour
2 tsp baking powder
1 tsp baking soda
½ tsp cinnamon
¼ tsp ground cloves

1 ½ cups shredded zucchini (about 2 small)
½ cup unsweetened apple sauce
¼ cup apple juice concentrate, thawed (undiluted) – I use orange juice concentrate sometimes too
¼ cup maple syrup
1 Tbsp oil (sunflower or canola)
1 tsp vanilla

½ cup chopped walnuts

IMG_0257

Preheat oven to 350 degrees (F). Spray pan with nonstick cooking spray (I use a 8 x 11ish glass baking dish OR a regular loaf tin). In a large mixing bowl, stir together flour, baking powder, baking soda, cinnamon and cloves. In a separate smaller bowl, mix together remaining (wet) ingredients, excluding walnuts.


Pour wet ingredients into dry and mix just until dry ingredients are evenly moistened. Stir in walnuts and mix until evenly distributed. Spoon batter into baking dish and bake on centre rack for 50 to 55 minutes. Turn onto cooling rack and let cool completely before slicing or wrapping. It will keep at room temperature up to 3 days or refrigerate for up to 7 days.

open up your veins

I think I've alluded to the problem of how antibiotic use in factory farming leads to super viruses, but I don't think I've ever done a post about it. I heard a piece on the radio about it this morning, and then used google news to find some stories on the topic. The best one I could find was from the Los Angeles Times and called A healthy resistance to antibiotics.

The problem is this:
- The sheer unhealthiness of factory farming (the confinement, the injection of steroids, the lack of exercise, and even completely f%$*cking up the animals' diet as when cows, who eat grass, are fed soy and estrogen instead) would kill all the animals unless they were pumped full of antibiotics to try and keep them alive.

- Bacteria, viruses and pathogens such as MRSA are in the livestock and are constantly battling with the antibiotics fed to the animals. Through this battle they get stronger and become resistant to the antibiotics (which are the same drugs that humans use and need to fight infections etc).

- So, these antibiotic resistant pathogens then make their way into the human population, and since the pathogens have already encountered and defeated our medications while in the animal population, we no longer have any way to treat humans infected with the virus.

As the above mentioned LA Times article mentions, MRSA all by itself kills more people in the U.S. each year than AIDS.
The rise of bacteria such as methicillin-resistant Staphylococcus aureus, or MRSA, which kills more people in this country each year than AIDS, is believed to be a consequence of the overuse of antibiotics in humans and animals. Low doses of the medications have become ubiquitous in the livestock industry, mixed into feed to enhance growth and prevent the diseases that sweep through crowded pens.

A panel of experts found "clear evidence of adverse human health consequences due to resistant organisms resulting from nonhuman usage of antimicrobials," the World Health Organization reported in 2004.



Image is from an online article titled From Dyes to Peptides: The Evolution of Antibiotic Drugs. It also provides some nice coverage of this issue:

In the 1950s, it was noted that antibiotics fed to livestock increased growth rates and animal size leading and thus increased production. It quickly became common practice to include antibiotics in animal feed. When antibiotics began to be used as food additives, there was no regulation behind it. Any antibiotic including those used for human therapy could be used.

At the same time, it became common practice to house livestock in confined and concentrated quarters. Farm animals such as chickens when allowed to roam free have limited egg and meat production, so farmers began to collect large numbers of chickens together to increase production. Factory farming led to the rapid spread of infections throughout farms and the use of antibiotics vastly increased to try to counter it. With the common use of antibiotics in farming, resistant genes were emerging in livestock bacteria and residual antibiotics were being ingested by humans, contributing to antibiotic resistance in human pathogens.

Yippee-Kai-Yay: the research shows...

The "red meat tied to cancer" story has certainly swept the news industry. I like this story about the reaction of Saskatchewan cattle ranchers to the new study:

Ed Bothner, president of the Saskatchewan Stock Growers Association, questions those findings.

"There's societies that eat three to four times as much red meat or three to four times as much beef as we do," Bothner told CBC News. "And I can remember in my lifetime when our per capita consumption in Canada was over 100 pounds. Right now it is lower than 50, so I don't think it's the consumption of red meat, per se, that's the problem."

Joe Kleinsasser, the chairman of SaskPork, said that when he heard about the study, his first reaction was to dismiss it.

"These studies are a dime a dozen," Kleinsasser said. "One day eggs are bad for you, the next day you can't eat enough of them."


I'm sorry dude - BUT WHERE IN THE HELL are people eating three to four times more red meat than North Americans? That's goddamned ludicrous. And the other guy is priceless as well... these studies are a dime a dozen.... Yeah I know. Troll through the archives of this blog... there is NO END to the amount of research saying Whatever the f*&^k you do, don't eat red meat!

Wow - am I the only one who completely missed this Pew Commission Report that came out in April 2008?

Pew Commission Says Industrial Scale Farm Animal Production Poses “Unacceptable” Risks to Public Health, Environment

Washington, DC - 04/29/2008 - The current industrial farm animal production (IFAP) system often poses unacceptable risks to public health, the environment and the welfare of the animals themselves, according to an extensive 2½-year examination conducted by the Pew Commission on Industrial Farm Animal Production (PCIFAP), in a study released today.

Commissioners have determined that the negative effects of the IFAP system are too great and the scientific evidence is too strong to ignore. Significant changes must be implemented and must start now. And while some areas of animal agriculture have recognized these threats and have taken action, it is clear that the industry has a long way to go.

I found the Pew Commission report while scanning through the references at the end of this article:

If you don't have access to the journal "Primary Care" shoot me an email (check my profile) and I'll see if I can send you a copy.

Here are some exerpts:

On how hard it is to figure out what the healthiest diets are, when our whole lifestyle is so sick

Even if the POEMs needed for evidence-based dietary counseling and farming practice recommendations are available, there is the difficulty of applying proven interventions to a population that has such a high rate of lifestyle-associated disease. This is a population that has continued to gain weight and become diabetic at ever-increasing rates in the face of improved food label reading and dietary changes as reported in Healthy People 2010. Trying for different results while maintaining the basic elements of a lifestyle that already has caused poor health could explain why only a small portion of proven dietary interventions have been shown to improve long-term health or longevity.

Quote from Diet for a New America on the benefits of adopting a vegetarian diet

“The effects on our physical health are immediate. The incidence of cancer and heart attack, the nation's biggest killers, drops precipitously. So do many other diseases now demonstrably and causally linked to consumption of animal proteins and fats, such as osteoporosis … hormonal imbalances causing miscarriages and aberrations of sexual development similarly drop away, as we cease ingesting with our meat, poultry and milk the drugs pumped into our livestock. So do the neurologic disorders and birth defects due to pesticides and other chemicals, as we begin to eat lower on the food chain where the poisons are far less concentrated … We find that the grain we previously fed to fatten livestock can now feed five times the U.S. population; so we have been able to alleviate malnutrition and hunger on a worldwide scale … We find ourselves also relieved of fear. For on a semiconscious level we knew all along that the old disparities in consumption were turning our planet into a tinder box, breeding resentments and desperations that could only eventuate in war.”

On the blood type diets like Eat Right for Your Type

Blood-type diets claiming benefits from different dietary components based on genotypes[37] are dismissed commonly as baseless theory.[38] Evidence is scarce and limited to secondary prevention. The most interesting study showed that a particular blood type in diabetics predisposed to more effective low-density lipoprotein lowering in response to increased dietary fiber.

Antibiotic Use

Cattle in 83% of United States commercial beef and dairy feedlots routinely receive antibiotics for disease prevention and to promote growth, resulting in the use of over 24 million pounds of antimicrobials annually for nontherapeutic purposes.
Many of these antimicrobials, such as tetracycline and penicillin, are important for human use. Drug-resistant bacteria and pathogens have emerged because of the widespread use of antibiotics in the animal reservoir, and these theoretically are able to be passed to people through the consumption of meat products. Health implications of antimicrobial resistance are infections that otherwise would not have occurred and increased rates of treatment failures and infection severity. An antibiotic-resistant urinary tract infection already may have been linked to this practice.

In general

This article is an overview of research on diets and nutrition, and the most common theme is this one:

For now, amelioration of unhealthy choices may be the best approach. Serial substitutions using nonanimal foods and snacks to reduce animal product consumption over time, encouragement of daily vigorous exercise, and increased consumption of organic and locally grown foods appear to be the best strategies toward that end.

End hunger by having a sirloin?

A local community group just started advertising something they're doing to raise money for a food bank - it's obvious that no vegetarians or vegans were part of this. The premise is that you have a steak dinner at a local restaurant for $20.00, and $2.00 from each meal goes to the food bank.

I couldn't help myself. I wrote the community group a nice email detailing the intimate connection between the meat-rich (particularly beef) diet and world hunger.



I came across some neat stuff while writing my email.

In the Independent Online I found The Big Question: Is changing our diet the key to resolving the global food crisis?

How does eating meat cause hunger?
Because it is a very inefficient way of producing food. It takes 8kg of grain to produce 1kg of beef, and large tracts of forest have been cleared for grazing land that might have been used to grow crops. Chicken is more efficient to produce – it takes 2kg of feed to produce 1kg of meat. To maximise food production it is best to be vegan. According to Simon Fairlie, in his magazine The Land, it would take just 3 million hectares of arable land to meet Britain's food needs, half the current total, if the population were vegan.

From WorldWatch, 2004, 17(4) pg12-19 I found a fairly devastating (for the meat industry) article with the very long title Now, it's not personal! But like it or not, meat-eating is becoming a problem for everyone on the planet.
Here's an excerpt from the article abstract:

As environmental science has advanced, it has become apparent that the human appetite for animal flesh is a driving force behind virtually every major category of environmental damage now threatening humanity - deforestation, erosion, fresh water scarcity, air and water pollution, climate change, biodiversity loss, social injustice, the destabilization of communities, and the spread of disease.

The WorldWatch group is biased by the way. I happen to think they're right and I agree with them, but they're the group behind Happier Meals (which you can find a free copy of if you google it) and they've been on about the meat industry for a long time now.


Here are the other links I provided in my letter to this community group, some of which you've seen before on this blog:

from Irish research to Vancouver newspapers

While pissing off vegans everywhere, here is a good illustration of something like the joke about how there are three types of lies (punchline being - Lies, Damned Lies, and Statistics). In this case, we have the grey fuzzy gap between research, and how research gets portrayed in a newspaper.

First - the Vancouver Sun runs a story called Vegan diet tied to birth defects.

So read that, but then definitely read a follow up piece in the same newspaper called Is eating vegan while pregnant as bad as smoking and drinking? What you are particularly going to want to read are the string of comments below this piece, where pissed off vegans tear both stories to shreds.

A) All the hoopla in both stories is about women who are B12 deficient. Vegans are not necessarily B12 deficient... especially mothers who have probably read up on this and are taking their supplements.

B) The data in the study is 20 years old (which is fine) but comes from a test group in Ireland where neural tube defects are already common - i.e. this is already a fairly biased test group.

C) None of the women in the study actually identified as vegetarian or vegan - some happened to have low B12 levels... and no offense... but in Ireland in 1989 they were probably meat eaters, not veggies.

Food and sustainability

I knew that the meat-rich diet was bad for the environment, but until the last few days I didn't realize that meat production emits more greenhouse gases than the international transportation industry.

I put together some details on this for a little project at work, and thought I'd post it up here as well.



Guess what – more and more research is showing that you can more to reduce your carbon footprint by going vegetarian, than by switching from an SUV to a hybrid car.

In 2006, the United Nations Food and Agricultural Organization released Livestock's Long Shadow, which identified the meat industry as a greater producer of greenhouse gases than the entire international transportation industry.

New Scientist magazine agrees, stating in 2008 that a family's food consumption accounts for double the greenhouse gases as their household driving habits.

The industrialized production of meat (approximately 15 billion animals each year in the U.S. alone) is an incredibly carbon intensive process. The problem begins with the fact that it takes 7 tons of plant protein (cows in industrial farms aren't fed grass, but soy, which can be eaten by humans) to make 1 ton of meat protein – resulting in 6 tons of wasted food (and wasted farmland, fertilizer, pesticides, oil/energy, and tremendous amounts of wasted water).
Not only does the production of meat create greenhouse gases, but by replacing forests (which act as carbon sinks to soak up C02) with farmland to grow soy for the animals, the meat industry reduces the planet's natural ability to absorb greenhouse gases. As well, cows account for approximately 40% of all the methane in the atmosphere.

In a February 2009 report, Stehfest et al state that the combined problems of methane, the C02 emissions caused by the meat industry, and the elimination of carbon sinks, are so significant that a worldwide switch to a vegetarian diet (however unlikely) would achieve the equivalent of $20 trillion spent on other climate change solutions (such as carbon sequestriation).

In Plan B 2.0: Rescuing a planet under stress and a civilization in trouble (looks like a version 3.0 was just released), Lester Brown writes that at a North American level of food consumption (ie heavy on meat), the planet can support 2.5 billion people, while at the other extreme, on the more veggie Indian diet, the earth could support 10 billion people (there are 6 billion people on the planet right now, with 9 billion expected by 2050).

Apart from greenhouse gas emissions, the industrialized meat industry creates many other environmental problems, including the toxic waste lagoons caused by pig farms (which create as much waste as cities the size of Cincinnati) and the reduction of oxygen levels in water bodies like the Gulf of Mexico, which kills all sealife in these areas.
