One thing that I ended up doing a fair bit of research about this semester was Veganism. Both personally, as well as for class: I set myself a goal of being vegan for one month for my International Nutrition class as part of an assignment with the goal of helping alleviate world hunger. The reason that I chose to be vegan, as opposed to any of the other suggested ways to make a difference was mainly because I believe that change must come from each of us, alongside the efforts of specific groups and governmental policies.
Veganism is touted by many people in our western world as a supreme diet in for three main reasons: it’s cruelty-free, better for the environment and better for our health. For my purposes, I focused on the fact that it is said to be better for the environment, as this is what has the most effect on world hunger.
The production of livestock, poultry, dairy and eggs is known to have huge effects on the climate. As Kim Barnouin, a strong vegan advocate who has now written several persuasive books on the subject, succinctly lists the, “five major ways that food systems are contributing to our demise: 1. Greenhouse Gas Emissions, 2. Water Supply and Pollution, 3. Deforestation, 4. Lack of Biodiversity and 5. Fish Depletion.” (Barnouin, 2010, pp. 17-20) Of course, I think that many of us as GRSers are well aware of these impacts.
With this in mind the fact that “Animal agriculture makes a 40% greater contribution to global warming than all transportation in the world combined,” and, “is the number one cause of climate change.” (Foer, 2009) means that one way to make a difference is to try and mitigate climate change through diet change. Stehfest et al. (2009) in their research on the, “Climate benefits of changing diet”, found that, “a global food transition to less meat, or even a complete switch to plant-based protein food [would] have a dramatic effect on land use, …methane and nitrous oxide emission would be reduced substantially.” And concluded in their study that, “dietary changes could therefore not only create substantial benefits for human health and global land use, but can also play an important role in future climate change mitigation policies.”
However, being vegan was extremely difficult for me. I did not expect the unpleasant effects on my digestive system which resulted from such a sudden change in diet. The physical difficulty made the challenge I’d created for myself more difficult than I had expected. However, when it came to making meals and food, I found that I was quite inspired to create new concoctions in the kitchen, and to ‘veganize’ some of my favourite recipes. I discovered early on, thanks to the abundance of foodie blogs on the internet these days, that cashews make quite a good milk, cream or cheese substitute in many recipes, and this allowed me to avoid the over-use of purchased nut milks (which I’m not convinced are healthier than dairy!).
The whole process definitely opened my eyes to the fact that I am able to eat a vegan diet without too much effort in that regard. I found new recipes and options for breakfast, which have definitely inspired me to continue experimenting with a more plant-based diet.
In the end, however, I didn’t feel like I really made a difference. Not only because I failed to meet the goal that I had set out to, because I think that perhaps I would feel similar even if I had. It’s not that I don’t believe that the action I took doesn’t change anything, but it’s so hard to quantify such an impact. Stats and figures can lay it all out: “A low-fat vegetarian diet requires less than half an acre per person to produce that food. Compare that to 2.1 acres per person for the meat eater.” (Barnouin, 2012), “the current world grain harvest could support 2.5 billion at the average US level of consumption…and in the US, ~12.5% are consumed directly, [while] most are used at feed, and that’s where the big difference comes in” (Rideout, lecture notes, 2015), “livestock accounts for 70% of agricultural land and provides 15% of total food energy” (Rideout, lecture notes, 2015), etc. but it’s obviously hard to see the effects of this. They are not tangible. This though, is perhaps the crux of the problem: what we cannot see or understand, and do not feel, we have trouble caring about. Not to say that people don’t “care” or aren’t empathetic, but it’s difficult to take action when your actions seem futile. Perhaps if we were somehow more interconnected, and could feel the impacts of our choices more profoundly, either morally or physically, things would change.
Interestingly, I discovered through my research that the debate about whether or not humans should be eating meat has been going on for almost as long as agriculture itself: Plato wrote a dialogue between two characters almost 2, 500 years ago debating the consumption of animals, in which one character, Socrates, tells the other, who wants to feed his citizens meat, that, “ this luxurious city will be short of land because of the extra acreage required to raise animals for food. I thought that this was incredible!! We’ve been having this debate for almost as long as agriculture has been around!
The thing that connected with me most strongly was reading a book called The Vegetarian Myth. I am undecided as to whether or not this was because we tend to find reasons to support things we already believe in (Plous, 1993), but regardless, it had a profoundly impacted the way I see things. It doesn’t help solve world hunger. But it made me think about food choices a little bit differently. The author, Lierre Keith, had been vegan for twenty years before she wrote the book, and had switched back to an omnivorous diet for several reasons. The part that hit home was I her introduction, where she described how, in her early twenties, as a keen and principled new vegan, she had tried to start a backyard garden. To her dismay, her plants were not doing well. In order to remedy the problem, she began to search out soil amendments. However, she then was faced with an interesting choice: either buy industrially-manufactured minerals, or add bone meal, or blood to her unhappy tomato plants in order to get them to grow. And so she was faced with an inevitable fact of life: things must die in order for other things to live. Without death, the carbon cycle is not complete, and things would not go on as they do. Veganism is an attempt to remove ourselves from this inexorable circle of life. This also sheds light on the fact that even plant-based diets require inputs that are not always positively affecting our world.
On a less profound scale, the nutritional side of it also made me re-think things a bit. There are many vegan books which claim that a purely-plant based diet is the route to the holy grail of health, and despite the fact that I do think I would perhaps have to give it a longer period of time before really knowing how I truly feel once my body adapts – Campbell, T. & Campbell II (2006) state in their book that, “the first moth can be challenging, but it gets much easier after that”.
Despite already being aware of the damage which our food systems cause, and the implications of our diets, this project made me much more acutely conscious of my food choice. I have already researched where I can get raw milk in the lower mainland (illegal, I know, but I do believe that more natural products are healthier), and last time I went to the supermarket, purchased organic eggs and local, grass-fed yoghurt. I am also aware that my choices are being made from a place of privilege. In the future, I would like to have my food choices be flexible. I intend to incorporate more plant-based foods into my diet, and focus on eating locally. I realise that eating locally isn’t always the most sustainable option, but I firmly believe that being more connected to the whole process – from the seed to the production to the harvesting and sales – is an essential step in understanding and thus transforming our food systems. My goal is to one day have a farm, where people can re-connect with their food. I have always wanted to have a mixed system (plants as well as animals), as I believe that that is what functions most holistically. Stehfest et al. (2009) also point out that, “a global transition to a low meat-diet as recommended for health reasons would reduce the mitigation costs to achieve a 450 ppm CO2-eq. stabilisation target by about 50% in 2050 compared to the reference case.”
This knowledge, combined with the echoes of Lierre Kieth’s book The Vegetarian Myth, have led me to the conclusion that awareness, balance and understanding are the most important things when it comes to making change: without awareness, there is no reason to start, without understanding there is not motivation to continue, and without balance, we soon lose sight of the goal as we struggle to find the pieces without looking at the whole puzzle.
