EATING A SLICE OF HUMBLE PIE
– Get comfy guys, cause this is a long one-
A few months ago, I was at a shoot and the interview was about food (obvies, my favorite subject). The interviewer asked me, “What is a daily act people can do to make the planet healthier and society better?” I answered that I believed buying seasonal foods from local farmers markets makes a major difference (I still stand by that). I also added that I didn’t think being a vegan would save the world because food systems are incredibly complicated and hardly anything is linear. As a quick example, soybean production (tofu) is a major contributor to deforestation in the Amazon (as I’m sure you know deforestation = horrible for emissions/the Planet/biodiversity/etc., etc.) Just as I said that, the photographer walked by and interrupted that soy was not the issue and that being a vegetarian (like him) is the best thing you can do for the environment. I pushed back. I told him that I used to be a vegetarian for the same reason (true fact), but my graduate studies told me a different story. Really, being a local/seasonal vegetarian is the best thing you can do for the planet. Buying tropical fruits and vegetables in the middle of winter in NYC, for example, is not doing anyone (including the Planet) any favors. I also argued that, depending on your climate zone and the time of year, a steak from a small, local, organic farm would be a better choice as far as emissions. All of this got published, by the way… [peekaboo_content]
Well, I just wanna issue a BIG FAT APOLOGY to Matthew Stone (photographer) and eat a big piece of HUMBLE PIE, cause YOU WERE RIGHT and I was wrong. An EPIC-Oxford cohort study released in July (2014) made it clear and official that vegetarian/vegan diets are the most environmentally friendly diets (Though, I still have a few questions that I’ll get to later…)
In my defense, when I studied this at the London School of Economics things were not so clear. When I was reading up on this, there was a lot of theory, counter theory, and counter-counter theory. I used to leave the library with my head spinning, not knowing what the hell to believe, and would just go home and eat my feelings (usually in the form of Cadbury’s Fruit & Nut Bars).
What’s different about the EPIC-Oxford study? Well, as far as I know, it’s the first major empirical study on diets as related to greenhouse gas (GHG) emissions. This means that researchers actually tracked, measured, and analyzed what subjects ate and tallied up all the corresponding GHG emissions. Oh, and the researchers surveyed the diets of about 55,504 meat eaters, pescatarians (vegetarian diet + fish), vegetarians, and vegans. (Can you imagine the insane amount of data and number crunching? It makes my head spin just thinking about it!!) The question they aimed to answer is “What constitutes a healthy, sustainable diet?” Here are the Cliff Notes of what they found:
- The majority of emissions related to food come from the agricultural stage.
- Technology could help decrease emissions to some extent, but it really comes down to changes in consumption patterns i.e. what/how we eat.
- An average 2,000 calorie meat diet had 2.5 times as many emissions as an average 2,000 calorie vegan diet.
o Shifting your diet from HIGH MEAT > LOW MEAT would reduce an individual’s footprint by 920kgCO2/year.
o Shifting your diet from HIGH MEAT > VEGETARIAN would reduce carbon footprint by 1,230kgCO2/year
o And shifting your diet from HIGH MEAT > VEGAN would reduce by 1,560kggCO2/year.
o Surprisingly, pescatarian diets had only slightly more emissions as a vegetarian diet (about 2.5% difference)
What the hell does a figure like1,560kgCO2 mean anyway? Well….
• A person traveling from London to NY has a carbon footprint of 960kg/CO2e.
• A family running a 10 year old small, family car for 6,000 miles has a carbon footprint of 2,440kgCO2e.
So, if you’re a vegan or vegetarian, take a minute to pat yourself on the back. No really, go ahead and take a minute. We’ll wait…………..
Now, if you’re like me, i.e. not a vegetarian (and definitely not a vegan), this study was tough to read. Also consider the fact that the study defines “high meat diet” as more than 3.5 ounces per day. 3.5 OUNCES = ONE CHICKEN BREAST (I’m repeatedly banging my forehead right on the table right now). SIGHHHHH and UGGGHHHHHHHHH.
OK, soooooo with this in mind, I am personally making a commitment to eat WAY less meat, with an aim to go fully vegetarian (with an eye on nutrition, of course). Additionally, from now on I will also make a real effort to ensure that Impatient Foodie has more vegetarian (and vegan) recipes than meat based ones. And yes, for the record, I tried being vegan awhile back and it was a bad experience on many levels (another story for another time).
So here’s my opinion on this: I am willing to accept these findings and happy to adjust my eating habits/lifestyle, but I am also unclear on the global implications of this study. Can a “prescription” of a vegetarian/vegan diet be the case for every single person in the world, regardless of geographical location/climate zone? Grad school trained me to be wary of “global” thinking and “silver bullets” and I smell a hint of that here. As Laura B. DeLind has written, “one size, one solution, one set of prescriptions (does) not, (cannot), fit all.”
And OK, I understand that the majority of food emissions come from the agricultural phase, but it seems weird to me that if I buy and eat a bunch of vegetables imported from Israel, South America, and Africa in the middle of winter I am having less of a footprint than if I eat a steak from a small scale, organic meat farm less than 100 miles away from NYC. I wonder if organic, small-scale meat farms with local distribution were assessed in this study? Or maybe the focus was on large scale, factory farm operations and their impacts?
The reason I fret about shipping around vegetables and fruits is that they are mostly made of water (80%-95% of fruits and veg are water). As Joan Dye Gussow said in her book This Organic Life (2002) “…the high water content of (fruits and vegetables) and their tendency to rot if they get warm means we are, in effect, burning lots of petroleum to ship cold water around.”
So, to be clear, I still stand by what I said in my interview: Eating local and seasonal fruits and vegetables (organic whenever possible) has a huge, positive impact. What is also clear is that meat based diets are heavily “emissioned” (I just made up that term – BOOM!) However, this study showed that eating LESS meat can also have a significant impact, if you feel you cannot give meat up all together. So another way forward is to eat a lot less meat and a lot more seasonal/local vegetables, fruits, grains, etc. When you do eat meat, consider enjoying it as a side dish rather than as a main course! If meat was considered a side dish for everyone, I wonder what impact that would have?! Any single animal would be able to feed many more people. Enjoying meat as a side dish is actually a suggestion my mom came up with awhile back and I think it’s kinda genius, especially in light of this study. As usual the lady is ahead of her time..
So basically, I’m happy to make a change, but wary of any silver bullet solution and have some questions/reservations. But, again, I will make a real effort to reduce my meat consumption. If anyone has any answers to my questions, please post them in the comments section! I’d love to start a discussion about this 🙂 Complicated and important stuff!
