So you have decided to cook dinner at home tonight. You go to the store and you buy some pork chops, some greens, some potatoes and all the assorted ‘fixins’ that go with your meal. You head home and you dice your potatoes, coat them with olive oil, sea salt and black pepper, and then throw them in the oven which is heated to 400 degrees. Next, you season your pork chops with Dijon mustard, black pepper and coriander and let them sit for a moment. You then wash and cut your greens and set them aside. You turn your attention to the skillet that you have been preheating on the stove, it looks hot. Now you take your marinated chops and you place them into the hot skillet, searing them on each side and then lowering the heat to cook them through. As the chops near completion you place your washed greens on the plate and top them with gruyere cheese and walnuts; you finish them with a light balsamic vinaigrette. Turning back towards the stove you remove the chops from the skillet and plate them. Finally, you open your oven and pull out your casserole dish of potatoes and situate them between the chops and the greens. Voila, dinner is served.
This process, when explained in detail seems like quite the accomplishment, but even more astonishing than the shopping and preparation process is the entire interconnected web of events that have come together to make your dinner possible.
Take that little pile of greens for example; where did they come from? Let’s say that you live in Oklahoma (like me) and the greens came from Napa Valley, California. That means that those greens, which let’s assume are not organic, were shipped over 1700 miles to get to your plate.
Consider the amount of energy that was required to transport your salad to your plate. Seventeen hundred miles at roughly seven miles per gallon equals 242.9 gallons of diesel fuel to make that meal happen. If diesel fuel is $4 per gallon, that is nearly $1000 dollars in transport costs, not counting maintenance.
That is a LOT of fuel to get those greens to your plate… but let’s talk about the green revolution. If you are unfamiliar with this concept, please read the linked article. In short: During the mid to late 1960s, agriculture was transformed by the introduction of genetically altered strains of crops, chemical fertilizers and pesticides. The resulting yields were much higher when compared to pre-green revolution agriculture yields. So what is the problem with higher yields? The issue is that it is extremely inefficient, meaning that it uses huge amounts of oil, manpower and electricity to produce negligible increases in total output. Also, the practice is generally not considered to be congruent with proper “land stewardship techniques.”
I’m throwing this ‘land stewardship’ term around without
really explaining it. Really, it is the application of Good
Agricultural Practices (GAP) versus ‘bad agricultural practices’ such
as excessive use of fertilizers/pesticides and insufficient crop
rotation. Do you know if your greens were GAP certified? If so, then
you could say that you are eating a ‘sustainable salad’.
So we have discussed the growing practices, the shipping
mechanisms, and in minimal detail, the harvesting process (just that it
is mechanized). What about labor practices? Do you know whether the
workers that harvested and packed your greens were paid properly or
treated fairly? Check out this article from Oxfam for more information.
Moving on from your greens, let’s take a look at your pork
chop. Have you ever considered the series of events that take place in
order to get that pork chop to your plate? Chances are the pig that was
slaughtered to make your pork chop was raised in factory farming
conditions. Similar to the green revolution, factory farming aims to
introduce a control over natural process in order to increase
production output. Because a life is involved in the process, many
folks are opposed to the conditions that animals must endure in factory
farming operations. The Encyclopedia Britannica Advocacy for Animals
website is a great resource for those of you that would like more
information about factory farming practices.
A problem with both industrial agriculture and factory
farming is runoff from the massive operations. According to this
article from the Environmental Protection Agency, agricultural nonpoint
source pollution (runoff as opposed to a pipe spewing pollutants
directly) is the leading source of impairments to wetlands, and a
major contributor to contamination of surveyed estuaries and ground
Perhaps the most well known result of agricultural
runoff is the “dead zone” in the Gulf of Mexico, which is caused by
fertilizer runoff. Essentially, all the fertilizer and antibiotics and
other stuff floating around in the water of the Mississippi River
(which flows into the Gulf of course) causes the algae in the Gulf to
‘bloom,’ which then uses up all the oxygen in the surrounding water. No
oxygen means no life, hence the term dead zone. For more information
about this, check out http://www.smm.org/deadzone/.
Speaking of water, agriculture and ranching both
take massive amounts of water to sustain. Sometimes, huge agriculture
operations can pull more water out of the ground than is refreshed
naturally. This practice is known as groundwater mining, a name that
implies that once the water is pulled out of the aquifer (basically
porous rock that holds water like a sponge) it will not be replaced any
time soon. The rate at which the aquifer can fill back up is known as
its recharge rate, which for the most part operates on what I like to
call a “geologic scale,” meaning that it basically takes… well,
forever. Also, the water that you washed your greens in had to be
treated at a water treatment plant.
So far, we have covered the greens from the Napa Valley
that traveled to your plate (maybe in Oklahoma), the pork that was
likely raised on a factory farm somewhere in the United States (maybe
Iowa), and the ethical and environmental implications of both of these.
We have also discussed the conditions under which the farm workers must
labor. What’s left on your plate? Oh yes, the potatoes that were cooked
with the olive oil and seasoned with the sea salt and black pepper.
The olive oil was most likely produced near the
Mediterranean Sea, making its trip to the United States a very long
one. The fuel costs alone must have been astronomical, but of course
the olive oil didn’t make the trip alone. Sea salt is made from the
evaporation of salt water, meaning that it generally is produced in
coastal lagoons. It could have come from France, or Senegal or
elsewhere, and it likely made a long trip as well.
Beyond the ingredients used in your dinner, you also used
some natural resources. Most obviously, if you have a gas stove, you
used natural gas (i.e. methane) to roast your potatoes and sauté your
pork chops. In the past, natural gas was viewed as a nuisance or a
waste product of the oil industry and was routinely “flared off“
(burned as it was pulled out of the ground). However, as technology
marches on, more efficient ways of refining and transporting natural
gas have become viable, allowing for the overseas shipment of large
amounts of the stuff.
Natural Gas being Flared
So where does all of our natural gas come from? Well, the
largest natural gas field in the world is in Qatar, which is in the
Arabian Gulf… or the Persian Gulf, depending on who you ask (it’s the
same place, but different folks call it different things).
Now that you’ve reflected on the amount of time,
effort and resources required to make your dinner, consider the next
step – your body’s processing of the calories and chemicals you’re
about to consume. Is this food really good for you? Buying organic
food or meats that are “free-range” not only give you better insight
into the growing and harvesting practices of what’s on you’re plate,
they’re often more nutritious for you as well, solving the problem on
Your challenge with this 13 for Friday is to
consider the past 12 steps and reflect on your own ethics of food
growth and consumption. A great way to ensure that your food is grown
to your standards and ethics is to grow or raise it yourself (we did a
post about a community garden a few weeks ago), but there are also
plenty of healthy and environmentally friendly food options out there.
You can also keep informed of food movements like Slow Food, or the
George Mateljan Foundation, which promote both healthy growth and
consumption of food.
