Episode 19 - Personal Behaviour Changes and the Climate Crisis

This episode we were joined by Robert Miller, a progressive activist and organizer based out of Edmonton, Alberta. One of the groups he works with is Extinction Rebellion. Since this was an interview episode, a research note is a bit tricky to do. So, what I’ve done here is just include the prep notes that I did, to give a sense of themes.

Belief and the Climate Crisis 

Johnathan Safran Foer in We Are the Weather writes about the psychological difficulty that humans experience in truly believing climate science. What he means by that is that many of us know the climate science, but we don’t really believe it – not enough to really change the way that we live in the ways that the climate crisis demands.

One of the threads throughout the book is this question that he raises around his grandmother’s decision to leave her village when the Holocaust was beginning. And the decision of family members who stayed. All of them had access to the same knowledge, but there is something different going on when it comes to really believing it and acting on that belief.

And we see this a lot with the climate crisis, I think: this idea that we are in the middle of the greatest crisis that humankind has ever faced, that we know we have a decade to take radical leaps to prevent runaway climate change.

And yet my life goes on more or less as normal. And I think that’s the way it is for a lot of people. So, I guess my question is: how can we get people to really believe in climate change, in the deep-seated way that we needed to?

Climate Anxiety and Climate Grief

One idea is that we can’t really conceptualize the climate crisis until we acknowledge its ability to kill us. That’s a pretty heavy thing to accept.

Do you experience climate anxiety? How do you deal with it?

Of course, the other side of climate anxiety is climate grief – coping with what we’ve already lost and what we cannot save. I think for me at least, climate grief is harder to cope with than climate anxiety.

What would you say to people that are just starting to confront climate grief, or to even realize that climate grief is a thing?

Which Personal Behaviour Changes Are Best?

Nearly two-thirds of global emissions are linked to direct and indirect forms of human consumption. So, in theory at least, there’s a lot that we can personally do to address the climate crisis.

What, in your view, is the single most important personal behaviour change people can make to address the climate crisis?

Eating a plant-based diet

We’ve talked on the podcast before about the environmental benefits of eating a plant-based diet – whether that means going fully vegan or becoming a ‘flexitarian’ or ‘reducetarian’. By one suggestion, a climate-sensitive flexitarian diet would mean eating about 1.5oz of meat daily (or, about three hamburgers worth per week). And just a reminder from our previous episodes that the world is an animal farm – about 30% of the earth’s land mass is used for animal agriculture or animal feed. Emissions from food production could surge by 87% by 2050.

Robert, you’ve been vegan for a while. Was it the climate crisis that motivated you to become vegan, or something else? What advice would you give to someone who cares about the climate, but who is intimidated about the prospect of going vegetarian or vegan?

I just want to quickly highlight some of the other personal behaviour changes that are often recommended:

Reducing your food waste

GHG emissions associated with food loss and waste is as much as 8-10% of all global emissions.

Composting

By the time this episode comes out, we’ll have already released the zero-waste episode. In that episode we talked about how organic waste is the majority of garbage people throw away. Composting can help us fight climate change because landfilled organic materials produce methane, a super potent GHG.

In an episode on biogas, we talk about the potential for turning food waste into energy!

Driving less, cycling, walking, and taking public transit more

In 2010, the transport sector was responsible for over 25% of global energy demand.

Having kids?

There is one last lifestyle change that I want us to reflect on a bit, and that is having children. A lot of people worry about bringing children into a world that is quite likely going to look a lot worse in a generation than it does today. Others have concerns that producing more humans contributes to the increases in consumption that are causing the climate crisis. What are your thoughts on becoming a parent in the climate change era?

What’s wrong with fighting the climate crisis with personal behaviour changes?

Some articles say that lifestyle changes are the only answer to the climate crisis, while others say that we can’t address climate change through personal behaviour. So, who’s right?

Themes within this: inefficiency (there’s so much we cannot personally control); personal behaviour changes are way easier for some than others; and climate justice, environmental racism.

Do We Need Mandatory Rationing?

A lot of people have used wartime rationing as an example for how personal behaviour can address the climate crisis. For instance, Bill McKibben has said, “it’s not that global warming is like a world war. It is a world war. And we are losing.” The suggestions along this line usually include stuff like marshaling extraordinary public investment to build solar panels, wind farms, electrified public transit, tree-planting et cetera. It could also include meat rations and, more controversially, retreat and re-wilding.

What are some of the benefits and drawbacks of taking a wartime approach to the climate?

As we get closer to 2030, are we running out of other options?

The Green New Deal

One thing that I’ve started to hear a lot in climate discussions is how we need to focus on the opportunities of decarbonization as well as the costs. We often hear this in the context of the Green New Deal.

What is the Green New Deal, in a nutshell? What are some of the benefits that we could achieve from acting collectively on the climate crisis, aside from averting catastrophe?

Learn more about the Green New Deal for Canada.

How to Promote Collective Action Changes

Political scientists love to talk about climate change as a collective action problem. Basically what that means is that the benefits of addressing climate change are diffuse (and mostly in the future), while the costs are specific (and mostly in the present). So, there are huge incentives to free ride, which makes collective action difficult. Or, to put it in the slightly flashier language of journalist Oliver Burkeman: “If a cabal of evil psychologists had gathered in a secret undersea base to concoct a crisis humanity would be hopelessly ill-equipped to address, they couldn’t have done better than climate change”.

We hear this narrative a lot in Canada from climate delayers: that Canada is a small part of the world’s global emissions and we can’t take on climate change, so why bother. What would you say to that?And what about the idea that the world still needs oil, so someone has to supply it? What does collective action on climate look like, from your perspective?

How Can You Support Collective Action?

Vote!

Vote for the candidate that has the best climate stance. If you live in America, the Sunrise Movement identifies Green New Deal champions. What should someone do if they don’t see sufficient climate policies reflected in any of their major parties or candidates?

Sign petitions, write your MP, your MPP, your councillor

Petitions are helpful for advocacy groups, because it helps them talk to politicians. When an advocacy group meets with an MP, it’s a lot easier to get his attention when you can show that people in the constituency care about that issue. The Citizens’ Climate Lobby has good tools for talking about the climate crisis.

Go to climate rallies

Protests make issues visible, and crowd-size matters. Activists often talk about the idea that non-violent revolutions have, historically, usually been successful when they mobilize 3.5% of the population. (From Erica Chenoweth’s research). In September 2019, roughly that percentage of Canadians participated in the climate strike. Do you think anything has changed as a result of recent climate strikes? And if not, why not?

Donate to or volunteer with a climate group of a climate champion candidate

There is a lot you can do with your time as a climate action volunteer: door-knocking, calling, pamphleting, flyering, postering, et cetera. Let’s say a listener is interested in helping out, but showing up at protests isn’t something they’re comfortable with. What would you say to them? What are some helpful ways they could get involved?

Become a citizen climate scientist

If science is your jam, there are ways to get involved as a citizen scientist.

Bring up climate change in your social circles, even if it’s awkward

This is where I think personal behaviour can spur social change, too. Any tips on how to raise the climate crisis with climate agnostics in a way that won’t alienate them.

Personal Behaviour Changes ARE Collective Action Changes

That is why acting matters, even if it is small. Because “the most contagious standards are the ones that we model” (JSF). So be the person at the protest, even if there are only a few hundred people there – even if there are only a dozen people there. Try to reduce your carbon footprint. Go flexitarian, or reducetarian, or vegetarian, or vegan. The people who love you will notice. And when they change, even just a little, it matters.

Episode 09 - Veganuary

Veganism as a Set of Ideas and a Movement

History of veganism

The term veganism was coined in 1944 by a British guy named Donald Watson and a small group of non-dairy vegetarians. When they were creating the word vegan, they also suggested: dairyban, vitan, benevore, neo-vegetarian, sanivores, and beaumangeur.

And that is how the Vegan Society came to be founded. Veganism is, as self-described, “A philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of humans, animals, and the environment.” Veganism is still a bit more of a fringe lifestyle, which is why it is so much harder – whereas almost every restaurant today will have a vegetarian option that is not always true for vegans.

History of Veganuary

Veganuary is a campaign started by a British charity with the same name that was founded in 2014. In 2019, the nonprofit says that 250,000 people took the pledge to try a vegan diet. Veganuary also draws participation from 500 companies, and it has become a hub for launching plant-based products and menus. Veganuary is also supported by Joaquin Phoenix, who lobbied for the all-vegan menu at this year’s Golden Globes. The campaign also aims to raise awareness and to mobilize people into a mainstream vegan movement.

Why veganism?

Although there is a wide spectrum of vegans that have different justifications for their lifestyle choice, most vegans view animal welfare as one of the main reasons behind their choice. From an animal welfare perspective, vegans argue that vegetarianism just doesn’t cut it: dairy and egg family can be just as bad or worse for animal welfare.

The strongest version of the argument says that we shouldn’t use animals as an end at all – so some vegans view it as wrong to even, say, shear a very happy sheep for wool. But most vegans focus on the very real contemporary horrors of our modern food, clothing, and cosmetics industries. The famous historian Yuval Noah Harari (author of Sapiens and Homo Deus), called animal farming “the worst crime in history”.[1]

And many vegans explicitly take aim at the idea that humane meat is possible. Many of today’s “humane” standards, like cage-free eggs, still leave animals in cruel conditions.  

What about wild game? A lot of vegans have ethical issues with killing animals at all, but many will grant that this is a lesser harm than factory farming. However, from an environmental perspective, vegans will often point out that it would be impossible to feed the planet if everyone was consuming this kind of ‘humane’ meat (at least, in anywhere near the quantities that we do today). So, in some sense buying wild game or humane meat from local organic farms is a kind of modern indulgence for privileged aspects of society.

Veganism and whiteness

But the vegan movement has run into some issues of its own when it comes to race and inclusivity. 

For Indigenous people, hunting is a traditional way of life. Especially given the trauma that has been inflicted upon these populations continually since colonization, the ability to connect to traditions is an important part of cultural healing and resilience. Indigenous peoples will also point out that environmental stewardship and respect for the land and animals is embedded in their cultural traditions. So, from their perspective hunting is a morally justifiable part of their way of life. It’s also a crucial component of food sovereignty for Indigenous communities.

This is where vegan activists have sometimes come into conflict with Indigenous people. From an Indigenous perspective, some vegan activists have a White Animal Savior complex, which is inherently anti-indigenous. For example, in 2017 animal activists targeted a new Indigenous-owned and -operated restaurant in Toronto because it had seal on the menu. This was despite the fact that the restaurant (Kū-Kum Kitchen) made a point of vetting the hunters from whom they sourced their seal meat. For more on this issue, check out the documentary Angry Inuk.

More generally, vegan activism has also been criticized for racism against other communities. In 2003 PETA released an ad that related the poultry industry to the Holocaust. Animal activists have made similar associations between animal farming and slavery. 

We also need to talk about the connection between veganism and white nationalism, because Nazis ruin everything. Evidently, a sizable portion of white nationalists are vegan. This has something to do with the concept of “blood and soil” that is a bedrock of white nationalism. Apparently, Hitler was famously vegetarian, which I just learned. But if you recall the uncomfortable association between early vegetarianism and eugenics, it’s not all that surprising.

Finally, until recently been a lack of BIPOC representation in animal rights organizations. As this is starting to change, animal rights activists are becoming attuned to the need to become more intersectional. That means thinking seriously about oppression and developing strategies that are more inclusive.

If you want to be a woke vegan, Gloria Oladipo offers a few tips in an article she wrote for Afropunk. First, non’t culturally appropriate – vegan versions of cultural dishes should come from members of that culture. Next, support initiatives that make plants more accessible – food deserts are often in racialized communities, and solving that problem should be a first focus. Third, feature more BIPOC vegans. (Actually, polling has found that Black and Latinx Americans are vegetarian in roughly the same proportions as white Americans.[2] BIPOC individuals should be represented and should have leadership roles in the movement). And finally, show up for BIPOC causes – acknowledge that BIPOC go through a lot and be an ally.

A friendlier, more inclusive animal-free movement?

That new inclusivity focus has already benefited the movement immensely by underscoring the need to focus on institutional change, rather than individual lifestyle choices. This is one of the core points that Jacy Reese makes in his book, The End of Animal Farming. So, rather than shaming individuals for eating meat, the animal-free movement is now focusing on shaming factory farms and pushing for institutional change.[3] Reese argues that this is actually more efficient because it helps people to overcome status quo bias and mobilizes a wider base of support.  

This is helpful from a strategic perspective because most people already think factory farming is bad; they just feel overwhelmed by the problem and powerless to change things. 32% of Americans believe “animals deserve the same rights as people to be free from harm and exploitation” and another 62% believe they deserve “some rights”, according to a 2015 Gallup poll.[4] The increase in pro-animal rights attitudes over the 1990s and early 2000s is generally attributed to: urban pet ownership, cosmopolitanism, feminism, and religious trends (secularization and the increasing popularity of pro-vegetarian religions like Buddhism). In California, Proposition 2 (a ballot initiative to ban animal confinement in small spaces) drew the highest positive turnout for a citizen initiative in the state’s history.[5]

Tactics like animal farm investigations have also helped, by exposing the conditions in factory farms. The first modern animal farm investigation was carried out in 1992 on a foie gras farm, exposing force-feeding. In the late 1990s and early 2000s these investigations became increasingly popular. “A 1998 PETA investigation of a pig-breeding farm led to the first felony indictments ever for cruelty to farmed animals”.[6] The Humane Society of the US “released a ground-breaking undercover investigation of a California slaughterhouse” in 2008.[7] As these investigations gained prominence, the meat, dairy, and egg industries started to lobby for “ag-gag” laws to limit the ability of activists to document animal farm operations.[8]

Veganism as a Dietary Choice

Vegans don’t eat animals or animal-derived products. This obviously includes meat, fish, poultry, dairy, and eggs. But one of the most difficult things about going vegan is navigating all of the secret animal products in our food.

Animal-derived ingredients

PETA has a comprehensive list of animal-derived ingredients. Dummies.com also has a list. Theirs doesn’t include everything on the PETA list. But it has an easy-to-use layout.

Some of the most common animal-derived ingredients include:

o   Beeswax and honey;

o   Casein (a milk protein derived from animal’s milk), calcium caseinate, sodium caseinate;

o   Confectioner’s glaze, resinous glaze, shellac, natural glaze, pure food glaze (comes from a hardened resinous material secreted by the lac insect);

o   Gelatin (a gelling agent derived from animal collagen);

o   Isinglass (a clarifying agent used in making wine and brewing beer, derived from fish bladders);

o   L. cysteine (a dough conditioner in some pre-packaged breads and baked goods, often sourced from feathers or human hair);

o   Whey (the liquid that remains once milk has been curdled or churned and strained);

o   Carmine (used as a red dye, this is from ground cochineal scale insects);

o   Lactose, saccharum lactin, d-lactose (I found this in chips a lot; it’s essentially a milk sugar);

o   Vitamin D3 (not all, but most Vitamin D3 is derived from fish oil or the lanolin in sheep’s wool) and omega-3 fatty acids (similarly, mostly derived from fish but vegan alternatives are available); and

o   Additives beginning with E (e.g. E904) are often animal-derived.

Veganism tips and tricks

To find out if packaged food is vegan, first look for vegan labelling (“Suitable for Vegans”, “Certified Vegan”). Then you can look for allergen information (e.g.: “Contains milk, eggs, shellfish”). Allergen information won’t generally tell you about meat-containing ingredients, so you should also read the ingredients list. There are some items that can be vegan but typically won’t be (e.g. bread, candy, chips, and beer/wine).

Fruits and vegetables are weirdly not always vegan. That is because they are often coated with either beeswax or a resin called shellac. These make the fruit look prettier, and also can reduce moisture loss and delay rotting. Synthetic polyethylene wax (a petroleum by-product) and carnauba wax (a palm derivative) are common, though problematic vegan substitutes.

Meat substitutes

The first reference to plant-based food that mimicked animal flesh was about tofu in 965 AD. The Magistrate of Qing Yang (China) “encouraged tofu consumption as a more frugal alternative to animal flesh, referring to it as “mock lamb chops” and “the vice mayor’s mutton.””[9]

The first reference to vegetarian meat in Western civilization wasn’t until 1852, referring to a sausage-like mixture made by squeezing chopped turnips and beets.[10] The first recorded veggie burger was created in 1939,[11] and Tofurky was introduced in 1995.[12]

Beyond Meat and the Impossible Burger are two plant-based burgers that are designed to mimic the culinary characteristics of beef burgers. They were both released around the same time. Impossible Burger released its burger in trendy restaurants, whereas Beyond Meat went straight to households by retailing at Whole Foods.[13] The plant-based food industry is now big enough to have an industry association (the Plant Based Foods Association).[14] Major food corporations are now investing in plant-based start-ups or creating their own plant-based food items: Unilever has released its own eggless mayonnaise;[15] General Mills invested in a nut based cheese and yogurt company called Kite Hill;[16] and Tyson Foods invested in a 5% share in Beyond Meat.[17]

Cultured meat

Cultured meat is also called cell-cultured meat, cell-based meat, in-vitro meat, lab-grown meat, and clean meat.[18] In 1998 NASA-funded engineers successfully grew goldfish meat in vitro, but the first cultured meat that people admit to eating was an art exhibition of cultured frog meat created by Australian artist Oron Catts in 2003.[19] There are now four main cultured meat companies racing to the market: MosaMeat, Memphis Meats, Hampton Creek, and SuperMeat.[20]

Episode 03 - Ethical Teeth

One of the earliest lessons we learn in life is how to brush our teeth. We spend about 1,460 minutes every year meticulously scrubbing those pearly whites. Given how much of our time is going to dental hygiene, how could we calibrate this daily habit to match our values?

Toothbrushes

It pays to think about the sustainability of your toothbrush, since this is a product that you replace fairly regularly. It is recommended to replace toothbrushes about every three months, which means that you will go through a dozen of them every three years.

Waste-free mavens (like Trash is for Tossers) point to the virtues of bamboo toothbrushes. And they’ve got a very good point. In the US, somewhere between 1 billion and 3.5 billion toothbrushes are thrown away annually. That accounts for approximately 50 million pounds of plastic waste every year. The waste from discarded toothbrushes ends up in landfills and oceans. As such, toothbrushes are a significant cause of plastic pollution in our oceans. In total, between 4.8 and 12.7 million tonnes of plastic enter the ocean annually. Bamboo toothbrushes, unlike their plastic counterparts, will biodegrade if properly disposed of in a compost bin. There are plastic toothbrushes made from recycled materials (like this one), but ultimately these will still contribute to plastic waste.

On the sustainability front, toothbrushes with bamboo shafts are an easy choice. You can also buy bamboo toothbrushes with replaceable brush heads, which would reduce the amount of bamboo that you are consuming and disposing. Bamboo toothbrushes are now available in many grocery stores, as well as natural foods stores. You can also buy them online, but this often requires more packaging.

Things get a bit trickier when we move to the bristles of the toothbrush. There are some trade-offs. Vegans especially should take note: as this article highlights, you will have to choose between a fully-compostable toothbrush with pig hair bristles and vegan toothbrushes that use one of two nylon compounds for the bristles. The trouble with nylon is that it will not break down in a consumer compost bin.

Nylon-4 has been demonstrated to be biodegradable in lab studies, but it is not compostable. Nylon-11 is made from castor oil and can be recycled, but only if you remove them from the bamboo handle with pliers and find a nylon recycling facility.

My current toothbrush is from Brush with Bamboo. 

For the curious, we looked into electric toothbrushes and found this interesting article that compares electric vs disposable toothbrushes. Between the disposable heads, the batteries, and the energy usage of an electric toothbrush, we’ve decided we land on the side of disposable, especially if the handle is bamboo.

Toothpaste

Here’s how toothpaste works:

Toothpastes contain mild abrasives that scrub away plaque, which is acidic and breaks down the enamel. Fluoride strengthens/protects tooth enamel (the outer layer of the tooth). Some toothpastes also include: detergents (make the toothpaste foam); humectants (e.g. glycerin; these help the toothpaste to retain moisture so that it doesn’t try out); preservatives (prevent the toothpaste from growing bacteria); and flavouring/colouring agents.

If you’re interested in looking at the recipes Kyla used to make her own unsuccessful toothpaste, you can find them here and here.

What’s the deal with fluoride in toothpaste?

A lot of vegan and waste-free toothpastes out there do not have fluoride. This has to do with concerns about the health risks of fluoride, which are largely unsubstantiated. Fluoridated toothpaste has been shown to be safe and effective in preventing tooth decay. Too much fluoride can be bad - you shouldn’t be swallowing your toothpaste - but if used appropriately fluoridated toothpaste is a safe and effective way to prevent cavities.

The prevalence of fluoride-free toothpaste also has to do with regulatory rules. Essentially, whether or not toothpaste is fluoridated is a key determinant in how toothpaste is regulated. In the US, the Food and Drug Administration requires that toothpaste with fluoride in it be regulated as a drug and a cosmetic. Toothpaste without fluoride is regulated as a cosmetic. Cosmetic products don’t require FDA approval before they go on the market, whereas drugs do.

In Canada, if you put fluoride in toothpaste (and some other things), it has to be regulated as a “Natural Health Product” - which is the pathway for non-prescription health products like vitamins. Natural health products are a subset of the wider category of drugs. There are specific rules about the concentrations you can use, what safety statements need to go on the product (e.g.: do not swallow), etc. Toothpastes without fluoride are regulated as cosmetics. Producers of non-fluoridated toothpaste have to represent their product as a cosmetic. So, for example, a “kills germs” is a drug claim but “kills bacteria that cause odour” is a cosmetic claim. Natural health products require a licence before they can be sold, whereas companies just need to notify Health Canada that they are selling a new cosmetic. Cosmetics have to be safe, but regulation is complaint-based. So, it is more onerous to sell a fluoridated toothpaste, which is perhaps why so many waste-free/vegan toothpastes don’t have it.

When discussing fluoride in tap water and food, Kyla cited 123dentist.com, Metro Vancouver, and Epcor. When she decided to try adding cacao as a fluoride replacement, this is the study she was basing that information on. We don’t think there has been enough research to count on this as an actual alternative, and she probably added the wrong ingredient to get the benefits anyway, but she figured what the heck and tried it for fun.

Dental Floss

Dental floss is another product for which cruelty-free and waste-free objectives often clash. You can get waste-free dental floss made with silk. Silkworms are boiled alive in silk farming. So, if animal welfare is important to you, this may be a no-go.

There are vegan dental flosses, but they are usually made with nylon (a petroleum product which is difficult to recycle). And because it can’t be composted, nylon floss can end up in the ecosystem where it may injure or kill animals. So, nylon dental floss, too, is less than ideal for animal welfare.

I was able to find a brand that is both vegan and compostable. Flosspot Gold is made from corn fibre and coated with candelilla wax. It comes in a small jar, which you can refill. Flosspot Gold is less readily available than the silk Flosspot, which might make it difficult for you to find. You can buy it online, but none of the companies I was able to find have a plastic-free packaging guarantee. Sustain commits to reducing and reusing packaging where possible, so you may wish to go with them. If you are in Alberta, the Apothecary in Inglewood may also be an option.

Episode 02 - Alternative Milks

What Are Alternative Milks?

Alternative milks are milk and milk products that are made from plants. They are also sometimes called vegan milk, plant-milk or non-dairy milks (or schmilks, if you’re a Science VS fan). The market for alternative milks is growing rapidly around the world. US non-dairy milk sales increased 61% between 2012 and 2017, according to a study by Mintel.

The most popular alternative milks are almond and soy milk (80% of market share in 2018). Soy milk is the traditional non-dairy milk. It was first sold in the US in the 1950s. But there are lots of alternatives (e.g., coconut, pecan, cashew, quinoa, hazelnut, rice, coconut, pea). Non-dairy milk alternatives can be cereal-based, legume-based, vegetable-based, seed-based, or nut-based. Oat milk is a relatively new entrant, but it ascending quickly in the alternative milk market.

Globally, the alternative milk market reached about $18.5 billion USD in 2018. By 2024, it is expected that the global alternative milk market will reach $38 billion USD, according to market research. Although this is a widespread trend, demand is growing the fastest in the Asia-Pacific region

Major alternative milk brands include Silk, Almond Breeze, and Rice Dream. Some newer entrants include Oatly, Califia Farms, New Barn Organics, Ripple Foods, Innocent, Mooala, and Malk.

Which Alternative Milk is Best?

Health

A big portion of the market for non-dairy milk is driven by health concerns. While this is a perfectly good reason to choose one product over another, we didn’t focus on it because it isn’t an ethical consideration. Non-dairy milks are not nutritionally equivalent to cow’s milk (although some vegan milks are fortified with nutrients like calcium, vitamin D, and vitamin B12 to make them more comparable).
Kyla mentioned a couple statistics on global lactose intolerance, including that “65% of the human population has a reduced ability to digest lactose after infancy”. You can read more about that at the US National Library of Medicine website.

Animal Welfare

All of the alternative milks we’re discussing are plant-based, but they may not necessarily be vegan. Many of them are, but some use honey or other animal-based substances in some of their products.  Usually the company’s website will tell you whether their products are vegan or not.

Environment

Assessing environmental impact is complicated. No single indicator can give us a holistic impression of what is environmentally best. Some common environmental indicators include land use, water use, emissions, and energy intensity. Generally speaking, dairy milk fares poorly on all of these environmental criteria when compared with alternative milks. But it gets a bit more complicated when it comes to choosing which non-dairy milk is the best.

Land Use: It’s a Matter of L and D

Cultivating a crop takes land, and that means diverting land use from other purposes. Agricultural land use contributes to deforestation and climate change because it requires the conversion of existing ecosystems like wetlands and forests, which are carbon sinks. There can also be social justice issues when agricultural land use pushes people out of their communities. Agricultural land use is a big challenge because of its scale: agriculture covers about 40% of the world’s land area. So, if you are concerned about environmental issues, it’s best to support an alternative milk that requires relatively less land to grow.

On land use, all four of the mainstream non-dairy milks do pretty well. They are all substantially better than their dairy counterparts. And the four main non-dairy milks - rice milk, soy milk, oat milk, and almond milk - all require relatively similar amounts of land to produce. However, oat and soy milk are slightly worse than rice/almond milk.

There have been some recent reports about deforestation and the displacement of indigenous peoples as a result of soy farming. This is absolutely a concern, but keep in mind that 90% of soybean crops go into animal feed. So, most of the land displacement occurring from soy is actually consumed indirectly in the form of chicken, pork, beef, farmed fish, eggs, and dairy.

Land use is also connected to other environmental consequences. Fertilizer run-off can pollute drinking water and accelerate eutrophication.

Oat milk is an interesting alternative from the perspective of soil sustainability. Some experts argue that increasing biodiversity in crop rotations can help farmers to use less pesticides. Since corn and soybeans are the two staple crops in the typical rotation, some experts suggest that adding a third crop (like oats) to the rotation can introduce big improvements for water pollution, soil erosion, and crop yields.

Emissions: Cashews Don’t Fart

Food production is responsible for a quarter of all human-produced greenhouse gas (GHG) emissions. Dairy milk produces more than double the GHG emissions of its non-dairy counterparts, per glass. Amongst the non-dairy alternatives, there are minor differences - with rice milk at the high end and almond milk at the low end - but in general emission rates are similar.

Water Footprint

Water footprints measure the amount of water used to produce each of the goods and services that we use. It’s an important measure to think about, because so much of our water usage comes from indirect sources - from the water that is used to make the things that we buy. And it is especially important when we’re talking about food: about 90% of the water a person consumes comes from the food they eat or the water used to make it. We might drink 3 litres of water each day, but the average water footprint for a Canadian is 6,392 litres per day.

Water footprint is a big differentiator for alternative milks. Although almond and rice milk still have a smaller water footprint than dairy milk, they are much thirstier than soy and oat milk. A single glass of almond milk requires 74 litres of water to produce - more than a typical shower. This is because of the water intensity of the crop itself: almonds require six times more water to grow than oats.

As with most environmental metrics, it matters a lot where a crop is produced. That’s another thing that puts almond milk on the negative side of the ledger: almonds are a water intense crop produced mainly in California, a region which is at high-risk of droughts. And unlike crops that can be left fallow, almond trees require water even in drought years. In contrast, oat production is a lot less geographically concentrated.

Energy Use

We weren’t able to find much about the relative energy intensity of making alternative milks, unfortunately.

Labour and Human Rights

 Most of the information out there on non-dairy milk focuses on health and environmental sustainability. It was difficult to find information on labour and human rights, even though we know that agricultural workers can experience some of the most difficult working conditions.

1.3 billion people - approximately one-third of the global workforce are employed as agricultural workers. Agricultural workers are often employed informally, paid poorly, and subject to unsafe workplace practices. They are, somewhat ironically, among the most food-insecure. More than 170,000 agricultural workers are killed doing their jobs every year. And the risk of a fatal accident is twice as high in food production than in any other sector, according to the UN Special Rapporteur on the Right to Food. Although most of the agricultural workforce is employed in developing countries, working conditions are also a concern in wealthy countries, who draw on temporary migrant workers for much of the workforce.

Generally speaking, crops like almonds and oats are less labour-intensive to harvest than fruits like avocados. But there are still significant labour concerns. And this is an area seems to be largely missing from the alternative milk conversation. Having said that, there are a few alternative milk companies out there that have ethical labour policies.

Oatly, a Swedish oat milk producer, sources its organic oats (it also uses conventional oats) from Swedish oat producers that have KRAV-certification. KRAV is a third-party organics standard that meets European Union organics regulations. KRAV also has labour and human rights provisions, including housing conditions for migrant workers.

One newer brand called REBBL, which makes plant-based “elixirs”, claims to ethically source its primary ingredients -- although they don’t use a specific certification scheme.

The Winner: Oat Milk?

Oat milk has become the darling of non-dairy milk advocates. It has three times the protein of almond milk and twice the fibre (according to Mother Jones). It uses less water - and grows in more places.

Is it better to buy or to make your own non-dairy milk? For our money, we would choose to make oat milk. It’s super easy, uses less waste, and you can control what goes into it.
