The intriguing history and ethics of having a lawn

From a young age I had resolved to never have a lawn if I owned my own house. This might seem incredibly trivial, but as I’ll show, it isn’t. Lawns are something I have thought about again several times throughout my life, each time becoming increasingly validated in my decision to not have a lawn.

My first (and perhaps partially childish) motivation was a general dislike for gardening. My childhood home had a large garden and I helped out from time to time. I didn’t see the point at the time, though I understand now that there are some benefits to property value and people can derive some enjoyment from having a lawn (though I never really did).

Many years later, I learned an interesting fact from Yuval Noah Harari’s book Sapiens about the history of lawns. Here are some quotes:

A young couple building a new home for themselves may ask the architect for a nice lawn in the front yard. Why a lawn? ‘Because lawns are beautiful,’ the couple might explain. But why do they think so? It has a history behind it.

Well kept lawns demanded land and a lot of work, particularly in the days before lawnmowers and automatic water sprinklers. In exchange, they produce nothing of value. You can’t even graze animals on them, because they would eat and trample the grass. Poor peasants could not afford wasting precious land or time on lawns. The neat turf at the entrance to chateaux was accordingly a status symbol nobody could fake. It boldly proclaimed to every passerby: ‘I am so rich and powerful, and I have so many acres and serfs, that I can afford this green extravaganza.’” [bolded emphasis my own]

The last sentence really stuck with me. It seemed true even today – lawns are almost purely a status symbol. They don’t produce fruit or veggies and barely have a useful carbon storage effect. I felt more justified in my attitude towards lawns.

Around the same time, I had become convinced by arguments about wild-animal suffering. If you are not familiar with this argument, I strongly encourage you to see this introduction, but in short, it is plausible that many wild-animals (including invertebrates such as insects) have lives with more suffering than wellbeing. If you accept this, then at the least you should accept that it would be wrong to bring these lives in to existence (for the same reason it is wrong to bring farmed animals in to existence when they will experience so much suffering).

Creating a lawn can be an effective way of increasing insect suffering, as it increases the available plant biomass for insects to breed and increase their population. Brian Tomasik argues for having gravel instead of lawns to reduce insect suffering. Tomasik’s rough estimate shows that the amount of suffering one can reduce by replacing a lawn with gravel is immense.

Having lawns can even be bad for the environment, especially if you regularly mow them. The carbon that would otherwise be stored in the grass is cut off and released to the atmosphere via decay. Some carbon would be stored in the ground in the grass and humus still, however the emissions from mowing ones’ lawn should outweigh this. As an alternative, white gravel would reflect sunlight, having a net cooling effect compared to grass, which would absorb heat.

Long story short – I don’t ever want a grass lawn and I wish this view was more commonly held – it’s more important than it seems at first glance.

How effective is the ban on single-use plastic straws and bags?

Recently, Australia has had a wave of bans on plastic straws and plastic bags from being available at many bars, restaurants and supermarkets. The main objective appears to be to reduce the amount of plastic that ends up in the ocean (the famous Great Pacific Garbage Patch comes to mind). This plastic often breaks down in to microplastic – small particles that don’t further break down and end up being eaten by small fish, thus entering the food chain. A laudable goal to be sure.

However, given what I know about the relative effectiveness of interventions, I wonder if this is the most effective (or even relatively effective) at reducing plastic relative to other things one can do. I will note that I already have pre-existing opinions on this, but will do my best to make an unbiased assessment.

There are two ways to look at this. One is to consider the actions of an individual. In other words, how effective is it for me to stop using plastic straws and bags relative to doing some other thing. The other way is to consider it from the perspective of a business or other actor such as a campaigner who is seeking to get businesses stop stocking such items. I will focus on the first one. Examining the impact of working to reduce plastic bag and straw use in general relative to reducing plastic use in other cases seems hard and not well suited for a brief examination.

First, I will estimate the volume of plastic used in these two cases by the average Australian.

Plastic use from single-use plastic bags

Woolworths [an Australian supermarket] currently gives out more than 3.2 billion single-use HDPE plastic bags every year, and according to a 2009 study, about 1 per cent of those, or 30 to 40 million, find their way into the environment. [From here]

Woolworths isn’t the only source of plastic bags in Australia, but it’s a good start. We can probably assume that the 1% figure of these bags getting to the environment is representative of the bags as a whole. A fact sheet by Keep Queensland Beautiful states that Australians use 4 billion plastic bags each year. This doesn’t seem to agree with the previous stat, as it’s unlikely that Woolworths accounts for 80% of the plastic bag distribution.

For arguments sake, let’s assume 4 billion bags per year with 1% of those reaching the environment. That’s 40 million bags per year, or about 1.5 per Australian. Assuming you’re consuming about the average (or were before the bans and public pressure), switching from single-use plastic bags to an alternative should mean 1.5 less plastic bags in the environment per year.

I found it surprisingly hard to find a value for the weight of a single-use plastic bag. In lieu of just weighing one myself, the best I could do was this document from a website called fighttheplasticbagban.com which gave a value of 9.3 grams. This actually seems kind of high to me. This results in a value of 13.95 grams in the environment per person per year. I’m very open to revising this if someone can find a more reputable estimate.

I will also note that alternatives to single-use plastic bags aren’t necessarily better for the environment, and could actually be worse. Just one example of this is that a ban on plastic bags results in an increase in bin liner plastic sales. This is the same kind of mindless optimism I see in other areas including fair trade, organic food, and some renewable energies. Just because something sounds good, doesn’t mean it is better in all aspects.

A review of the ACT ban in 2012 found that bin liner sales had indeed increased by 31 per cent a year after the ban came into place.

But a second review in 2014 found that sales had settled back down to pre-ban levels. [from here]

Plastic use from single-use plastic straws

Australians use around 10 million plastic straws each day, or 3.65 billion per year. For lack of a figure I’ll assume 1% of these end up in the environment as well, giving a figure of 36.5 million. This gives about 1.4 straws less in the environment per person per year.

It was also hard to find an estimate of weight for plastic straws, but this paper suggests around 0.45 grams, or 0.63 grams in the environment per person per year. This gives a total of 14.58 grams in the environment per person per year from the combined sources.

We’ve examined the effectiveness of a ban on single-use plastic bags and straws. Let’s now look at two alternatives.

Alternative #1 – Veganism

A vegan lifestyle is well-known to significantly reduce ones’ impact on the environment in general (as well as farmed animal suffering), but lets’ suppose we are specifically interested in plastic. When one thinks of the Great Pacific Garbage Patch, images of plastic bottles and bags probably comes to mind. However, 46% of the total trash is estimated to be fishing nets (much of which is made of plastic), with the majority of the rest being miscellaneous fishing gear, not consumer plastics.

Accepting this, it still seems hard to estimate the relative impact of purchasing fish vs consumer plastics. With consumer plastics we can easily measure volume, however to estimate the impact of fishing we would need to calculate the volume of nets used per person per year, as well as the relative rate of loss to ocean of consumer plastics vs fishing gear. Simplistically, one could argue that since the volume of plastic in the ocean is mostly from fishing gear, eliminating fish from ones’ diet should have a greater impact than eliminating consumer plastics.

One estimate suggests 640,000 tonnes of fishing gear is left in the ocean per year. That’s an average of 84 grams per person per year (globally). However Australians consume around 28 kg of fish per year as of 2013, while average consumption globally was 16.4 kg in 2005. Assuming the fish Australians consume is about as plastic-polluting as the global average, we should multiply our 84 grams per person by 1.7, giving 143 grams.

Eliminating your use of plastic straws and bags might seem easier than adopting a plant-based diet for many people (though I’d argue it’s easier than you probably think), but you’d be kidding yourself if you thought you were having a big impact by doing only the former.

A cautionary note

Whenever I talk about the environmental benefits of a vegan lifestyle, I feel compelled to tell my cautionary tale. I believe it is possible that advocating for the environmental benefits of veganism could actually increase farmed animal suffering. In short, this is because the primary cause of environmental damage from eating animals is from red meat. If this causes people to eat less red meat and more poultry or fish, they would be causing more sentient minds to suffer, since it takes many chickens or fish to get the same volume of food as a cow.

This case is a little different, since I’m talking about the damage of fishing, but I would still encourage anyone convinced by my argument to try veganism rather than just eat no fish*.

Alternative #2 – Reducing other plastic use

It seems likely to me that the plastic from straws and bags is only a small part of what a consumer consumes, even if we ignore fishing nets. One has to wonder whether reducing their plastic use in other areas could have a vastly greater impact.

As of 2016, Australia produces around 3 million tonnes of plastic per year. Around 130,000 tonnes of this plastic is estimated to end up in the ocean each year. Interestingly, this is 4 times the proportion of plastic from bags that ends up in the environment. This gives 5.4 kg of plastic in the ocean total per person per year. I don’t know the spread of the different sources or how easy it is to do anything about them, but we can clearly see that the amount of plastic in the environment as the result of plastic bags and straws is very small indeed (0.01458 kg.pa vs 5.4 kg.pa).

It seems reasonable to say that reducing your plastic use in general would have a greater impact than just eliminating your plastic bag and straw use.

The ableism objection to banning plastic straws

Some have claimed that the ban on plastic straws is actually ableist, because some people rely on plastic straws to be able to drink. This makes sense, and I think the ban should perhaps be a little more nuanced to allow for this case (e.g. bars/restaurants can still give someone a straw if they need it for health/safety reasons). They could also use biodegradable or reusable straws, but not all of these are safe for the consumer (can pose a choking hazard, aren’t positionable, etc.).

However, one has to wonder – if someone is relying on a straw for safety reasons, why don’t they bring their own? Not all venues stocked plastic straws to begin with, so what did people who needed them do in those cases?

Conclusion

I think the ban on plastic straws and bags is ineffective. Not only that, I think it is a serious waste of time and money. One might retort with something like ‘it’s surely better than doing nothing’, but it gives people a false sense of achieving something and solving the problem. Of course, you could (and should) do all three of the above.

One surprising take away of this for me was that the plastic released to the environment from fishing was still a very small part of the plastic released to the ocean in general.

Some of my peers have started putting estimates on the time it takes to write posts like these, so I’ll start doing the same. This took me around 2 hours total to research and write.

* I’d like to share my disdain for pescatarianism here. It is potentially worse than doing nothing at all, but people think they are either reducing animal suffering or environmental damage.

Edit – It has been noted to me that the issue with straws is not just the volume of plastic, but the shape. It can pose a choking hazard more easily than some other plastics. Fair enough, but fishing nets also trap marine life pretty easily.

Two impactful things you can do this World Environment Day

Happy World Environment Day! Last year I wrote a post about what you can do for the environment. This year I’m doing something similar, but going for a lighter format. Enjoy!

https://www.pexels.com/photo/conifer-daylight-environment-evergreen-454880/

Days like these are great opportunities to reflect and make sure we are doing all we practically can to protect the environment. Today, I’d like to focus on two small things that we as individuals can do which are highly effective but not very often talked about.

Cool Earth

Within a particular cause area, some charities can be as much as 1000’s of times more effective than others. So if you’re going to donate to an environmental charity, it’s crucial to make sure your $$ are having the most impact they can. One stand out environmental charity is Cool Earth.

Cool Earth works to stop deforestation, and are so effective that $1.34 US donated to them reduces greenhouse gas emissions by 1 tonne of CO2-equivalent. As of 2016, this was one of the best charities for reducing GHG emissions.

The average American uses about 20 tonnes of CO2 per year as of 2006, so you could offset a years worth of emissions for just $26.8.

Livestock industry

Over the past few decades, the impact of the livestock industry on the environment has become increasingly clear. Below I’ve outlined a few key statistics to show just big the impact is (stats are relative to the average US meat eating diet).

Image from https://www.marketwatch.com/story/oil-prices-head-lower-as-global-tensions-continue-unabated-2017-08-11. Stat from http://www.cowspiracy.com/facts/.

Adopting a plant-based diet is more effective for reducing your CO2 emissions than forgoing showers, having solar panels, and using bikes instead of cars.

So what can you do about this? Well for starters, you should definitely consider not having any animal products today (I might be too late for that), but also you should consider having less or no animal products in the future. It’s becoming easier every day with increasing access to cheap, delicious plant-based food.

I initially stopped eating meat because I became convinced that it was one of the most effective things I could do to help the environment, and it was way easier than I expected. I’d like to encourage everyone to try it. Just start with one vegan day a week and work from there.

Great tasting food doesn’t have to contain animal products. If you live in Sydney check out Soul Burger for some plant based deliciousness, like this ‘chicken’ and ‘bacon’ burger (my weekly guilty pleasure)!

2017 Per Capita Young Writers’ Prize 1st place: Effects of Livestock Industry on Climate Change and the Environment

I’m pretty chuffed to have won equal first prize for the 2017 Per Capita Young Writers’ Prize. I was hesitant to apply at first, as I didn’t think an article about the livestock industry would be seen as relevant enough to do well, but I’m glad I tried. Below is the essay in full.

The question was: “If you were a Federal Cabinet Minister in a leading portfolio (Environment, Health, Education, Housing, Transport, Industry, Science, Treasury) what would be your principal policy priorities, taking account of the long-term national interest? Explain the reasons for your priorities and outline your strategies for implementation.”


As the Minister for the Environment and Energy of Australia, I have decided to focus my policy priorities on animal agriculture. This is based on extensive research and understanding of national priorities and risks, which will be outlined below. I have also presented a list of policy actions which I will seek to undertake over my term as Minister.

Effects of livestock industry on climate change and the environment

The 2006 report Livestock’s Long Shadow by the Food and Agriculture Organization of the United Nations discusses the environmental impact associated with animal agriculture. The livestock industry is responsible for 14.5% of global anthropogenic greenhouse gas emissions. Despite this, there is a disparity in where climate policy focuses. Climate debate and policy, both in Australia and internationally, rarely acknowledges the role that animal agriculture plays. There is a disparate focus on the energy and transport sectors.

Globally, the livestock industry produces around 130 times more waste than the global human population. This waste can contain a host of diseases, and if water ways become contaminated, can be a serious risk for human health. If the waste reaches the ocean, it becomes a source of major environmental degradation. The Australian livestock industry also uses a disproportionate amount of water resources. In Australia, there is a substantial level of protest around the expansion of fossil fuel extraction, especially the practice of hydraulic fracturing and its impact on water. Given the high water use of industrial animal agriculture, it seems likely that protest and attention will also turn to this industry.

Effect of the livestock industry on human health and animal welfare

Not only does this industry affect wild animals and environment, it also creates an immense amount of suffering for the animals used as food. Undercover investigations have revealed excessive cruelty and suffering as standard practice, particularly in industrial Australian pig and chicken farming. Many Australians are already against animal abuse. While we mitigate the environmental issue, we can also align government policy with the ethical preferences of Australians. The proportion of people who completely eschew animal products, vegans, is also a growing population, and will become a considerable voting force in its own right.

The health impacts of a diet high in animal products are non-trivial. Notably, the World Health Organisation announced in 2015 that they have listed processed meats as a Group 1 carcinogen (carcinogenic to humans), and red meat as a Group 2A carcinogen (probably carcinogenic to humans). While processed meat does not pose as much of a risk to cancer as tobacco, studies have suggested that a diet high in plant-based food leads to lower blood pressure, a reduced risk of type 2 diabetes, and a reduced risk of mortality from cardiovascular disease. As the Australian Government, we have a duty to protect the health of Australian citizens.

Case study – Impacts of climate change on the Pacific Ocean

Global analyses show the upper Pacific Ocean warming. Sea temperatures on the Great Barrier Reef have increased by about 0.4°C over the past 100 years (Lough, 2000). The Great Barrier Reef is an important Australian landmark. It brought US$4.48 billion to Australian businesses in the 2004/2005 financial year, and resulted in the employment of 63,000 individuals (full-time equivalent). It also plays a critical role in biodiversity.

The GBR is most under threat from rising sea temperatures (resulting in more intense and more frequent coral bleaching events), and ocean acidification (reducing the ability of corals and other organisms to calcify). The 2007 IPCC report on climate change outlines the risks to the Great Barrier Reef and likely outcomes in more detail.

Policy recommendations

A multi-level policy is proposed to achieve long-term national interests. We should gradually replace the livestock industry with plant-based farming. This is a trend we expect to occur globally regardless of our involvement, and it is in Australia’s best interest to start laying the groundwork for this transformative shift early. This can be done by reducing livestock subsidies and raising a small tax on animal products, creating disincentives for consumers and producers.

We should assist farmers as they shift from livestock to more sustainable produce. The revenue from the animal product tax can be used to facilitate this support, and may come in the form of grants for land use change or subsidies and tax breaks for producing plant-based foods. Arid land in Australia typically used for grazing livestock can be used to grow other foodstuffs such as almonds and dates, or be used for carbon sequestration.

We should support the Australian food tech industry to develop plant-based and cellular agriculture alternatives to animal products. Already we are lagging behind as USA and Europe develops this technology. We should provide the industry with subsidies and research & development credits. We should host international collaborative events to facilitate technology transfer, particularly with USA and Europe, and also aim to encourage new food tech businesses and partnerships in Australia.

Australia can become a respected leader in this space whilst much of the world lags behind in action on animal agriculture. Whilst Australia’s net emissions are relatively small for the region, our greenhouse gas emissions per capita are amongst the highest in the world. One of our greatest tourist attractions, the Great Barrier Reef, is in danger and relies on a healthy Pacific Ocean.

We should promote a plant-based, whole foods diet through national public health campaigns. Whilst also reducing the public-health burden of Australia, this will have the added effect of reducing the consumption of environmentally damaging animal products. This type of public health campaign has already been demonstrated to work through anti-smoking campaigns, and may result in savings based solely on the public health burden reduction. Our current national health guidelines do not reflect the latest body of evidence on the impacts of animal products, and the healthfulness of a diet high in unprocessed plant foods, and should be urgently reviewed. Other countries, including China, are already beginning to alter their dietary guidelines to reflect the latest evidence on health and environmental impact, and Australia is, once again, lagging behind.

Australia is also well poised to supply Asia with a range of healthy, environmentally friendly and cruelty-free food. As Asia moves out of poverty and demands more luxury foods, we can provide them with high quality meat alternatives. Vegan Australia is developing a series of recommendations for moving to an animal free agricultural system in Australia, which may be beneficial in formulating our own policy.

This is a multi-disciplinary issue, and it requires multi-disciplinary action. A committee of agriculture reform should be formed to facilitate these changes. The policy recommendations outlined here fall under the portfolios of the Minister for the Environment and Energy, the Minister for Health, the Minister for Agriculture and Water Resources, the Minister for Trade, Tourism and Investment, and the Minister for Industry, Innovation and Science, and thus each of these ministers’ offices should be directly involved.

Respected individuals, including Bill Nye, CEO of the Planetary Society, and Tom Hayes, CEO of Tyson Foods, are making public statements that they believe plant-based foods are the future, and they have good reason to think so. Through these policy recommendations, Australia stands to benefit financially both in the short and long term, ensure the long term sustainability of our agriculture and tourism industries, and align government policy with public values.

Policy brief: The role of the Australian food industry in climate change

I’m grateful to have been shortlisted for the 2017 APRU New York Times competition titled ‘The future of the Pacific Ocean’. Unfortunately, as I wasn’t placed in the top 3 my essay won’t be published, so I’m hoping it will get some use here. You can see the winners here.

The essay was pitched as a policy brief to key Australian ministers on the risks of climate change to Australia (specifically relating to the Pacific Ocean) and the role of the food industry as a solution. I focus primarily on a actionable solutions relating to a transition from an animal-based industry to a plant-based industry.

How you can make a difference this World Environment Day (June 5)

The political response to climate change from a number of countries, in particular Australia and USA, has been lacklustre. In the last few days, there has even been discussion of President Donald Trump potentially pulling out of the Paris accord. We can obviously no longer rely on governments to guarantee a solution. Many people have taken the first steps in reducing their environmental impact by swapping their car time for a bike or bus, adding solar panels to their home, or being more conscious of their water use. There is one option for reducing personal environmental impact that is surprisingly effective, but very often overlooked.

Adopting a plant-based, or vegan, diet is one of the most effective individual acts you can make to reduce your impact on the environment and CO2 emissions (more effective than forgoing showers, having solar panels, or using bikes instead of cars). Using American figures, on average vegans use 1/18th as much land for food as a meat eater, while vegetarians use 1/6th as much. Vegans also use 50% as much carbon dioxide, 9% as much oil and 8% as much water.

In 2006, the Livestock’s Long Shadow report (by the Food and Agriculture Organization of the United Nations) highlighted the environmental impact of animal agriculture. Of note, an estimated 14.5% of global anthropogenic greenhouse gas emissions are the result of the livestock industry.

Globally, farm animals produce around 130 times more waste than humans. This waste can be home to a range of diseases. If waterways become contaminated by this waste, it can be disastrous for human health. If the wastewater reaches the ocean, it can be a source of major environmental degradation, creating what are known as dead zones. The Australian livestock industry also uses a disproportionate amount of water resources.

The impact of climate change is increasing, and will continue to increase into the future, even with immediate action. Of particular note to Australians are the effects on the Great Barrier Reef (GBR). Over the last 100 years, sea temperatures on the GBR have risen by around 0.4°C. The combination of rising sea temperatures and ocean acidification will lead to more frequent and intense coral bleaching events and a reduced ability of corals and other sea organisms to calcify.

Rising land surface temperatures will also lead to more heatwaves, with the governments’ own estimates suggesting a quadrupling of heatwave related deaths in Australia by 2050. This will hit our ageing population the hardest. The World Health Organisation estimates that, from 2030 to 2050, an additional 250,000 deaths will result each year due to climate change.

In addition to the serious environmental impact of animal agriculture, there are a range of global health issues that can be simultaneously addressed.  A few weeks ago, an open letter was written to the next Director-General of the WHO (shortly after revealed to be Dr Tedros Adhanom Ghebreyesus), calling on them to recognise factory farming as a major global health challenge, and signed by notable individuals such as Noam Chomsky and Mark Bittman.

By this time next year, 700,000 people will have died as the result of resistance to antibiotics. The bulk of antibiotic use is not in humans, but in the livestock industry, to increase productivity and keep animals alive. With a growing global population, these issues will only get more serious.

In 2015, the World Health Organisation announced that processed meats are a Group 1 carcinogen (carcinogenic to humans), and red meats are a Group 2A carcinogen (probably carcinogenic to humans). A diet rich in plant-based food is suggested to lower blood pressure, reduce the risk of type 2 diabetes, and reduce the risk of mortality from cardiovascular disease.

Animal agriculture also creates unimaginable suffering for the animals themselves. Undercover investigations in Australia have revealed pain and suffering as standard, particularly in the industrial farming of pigs and chickens. Most people agree that needlessly causing animal suffering is wrong, and so by simply avoiding animal products, you can align your ethical values with your actions.

Living a compassionate and environmentally-minded lifestyle has never been easier. Increased demand for plant-based foods from vegans and non-vegans alike has lead to the creation of realistic animal product alternatives that are now readily available at supermarkets. With relatively little planning, a plant-based diet can be cheaper, healthier and delicious.

So while you consider your bike and solar panels this World Environment Day on June 5, why not give a plant-based diet a go as well? Bring the family together over a tasty meal and let your imagination run wild. Who knows, you might even decide that it was so easy you will want to keep going.

The Reducetarian Summit – thoughts

As you may have been aware, the Reducetarian Summit was on in New York city last weekend. I went because I was on the fence about whether the ‘reducetarian approach’ to animal advocacy was a good idea (I’ve written about that here), and I wanted to learn more. It was also a pretty great networking opportunity, and it is always nice to meet in person people you have been engaging with online for years.

I also had the pleasure of interviewing Tobias Leenaert, the Vegan Strategist, for my podcast, which you can find here. We talked about the pros and cons of a reducetarian approach. Tobias advocates for an ‘adaptive’ approach, which I like. It involves being flexible and using whichever approach works best for a given situation*. You can also find criticism of this discussion here.

Overall, the talks were mostly on par with what you might expect to see at a conventional animal advocacy conference. There were talks on the impacts of animal agriculture on animals, global health and the environment, as well as on cellular agriculture/plant-based meat alternatives and political lobbying. The main difference with a conventional conference was there a relative lack of discussion about animal rights.

Interestingly, it seemed like most people at the conference were vegan, which surprised me. I had figured that the conference might mostly appeal to people wanting to reduce but not eliminate their animal product consumption, but it seems to have been mostly people with the same mindset as me. They either wanted to learn about the approach, or wanted to improve their advocacy and network.

There weren’t really talks on the pros and cons of a reducetarian approach as I was expecting, so I can’t say I changed my opinion much. I slightly updated towards thinking that reducetarian advocacy could be good in some situations, but as I mentioned previously, I still hold reservations about the way it is currently being done by some people.

The conference was protested by about half a dozen individuals, lead by Harrison Nathan, who has been a critic of various aspects of effective altruism in an animal advocacy context. They stood out the front on the first day with signs, and I went to speak with them. Nathan and I have engaged online about his disagreement with the reducetarian approach, and I share many of the same reservations. I am glad to see that Nathan’s objections come from believing that reducetarian advocacy is ineffective, rather than the more deontologist belief that advocating for anything less than total veganism is always wrong.

I had advised against a protest for fear of it harming the reputation of vegans and reinforcing stereotypes, but I stand pleasantly corrected (as far as I can tell). The protest was very calm and reasonable, and for getting across their views, it seemed successful**.

One recurring theme of the panel talks was a general positivity towards organic food, and a general disdain towards GMO food. This frustrates me. I won’t delve in to the science now, except to say that there is no evidence, health or environmental, saying that we should preference organic or non-GMO food. In fact, GMO food can be designed to have higher food yields, be more nutritious, and more disease resistant. As my friend Michael Selden eloquently put it, “I’m an environmentalist so I’m pro GMO. It’s that simple.” The same Michael Selden (who runs a cellular agriculture fish company) was in a panel on cellular agriculture and spoke positively of GMOs, to my joy. It was a much needed voice in the dark at the conference.

Many people are pro-organic food because they are worried about pesticides, and think that organic food doesn’t have pesticides. This is false – organic food uses organic pesticides, which are not necessarily better and can be worse than synthetic pesticides. For example, copper counts as an organic pesticide. Also, while some pesticides can be harmful, they are probably on average less harmful than you think, and they do provide benefits to food yield etc. Without pesticides, we would need a lot more land and resources to produce the same amount of food. If anything, people should advocate for better and safer use of pesticides than for no use of pesticides.

I also just want to share an exchange I had at the conference which I found quite interesting. I was with a few friends who were all involved with the effective altruism movement, and we were chatting with one woman who had never heard of it before. After explaining the basic concepts, she said, ‘Oh that sounds great, but I’m not earning a lot of money, and I can’t donate much to charity, is there still a place in effective altruism for people like me.

The idea that effective altruism is all about money and donations is an old criticism, but it still comes up from time to time (not that it was necessarily a criticism in this case). But the point is just that taking a high paying job and donating a lot of money to effective charities is just one effective way to do a lot of good that people often overlook, not that it’s the only way. Depending on your situation (interests, skills, network and experience), it might be more or less effective than other things you could do. For example, you could do effective advocacy or research work.

I just found this exchange a good reminder to make sure the message is clear, because I really believe in effective altruism and don’t want people to get the wrong impression of it.

Below are some photos from the conference, including some of my favourite graphs and figures from presentations.

* A valid point was raised to me about saying that ‘it depends’. This could be harmful because it stymies discussion. We can say that it depends and is probably different for different situations, but when it comes down to something like actually putting a message on a leaflet, we need to know what to do.

** Again, a valid point was brought to my attention after writing this. I spoke with the protesters, but most people attending the conference didn’t. Their perception of vegans in general may still have been harmed by the existence/presence of the protest, as they didn’t have the chance to speak with them and hear their arguments or motivation.

It was great to see the three milk choices for coffee at the conference were all vegan (as was all the delicious food!), but even more amusing to see everyone excitedly taking this photo, myself included.

 

Morality is Hard podcast – Episode 4 – Tobias Leenaert, the Vegan Strategist

Tobias Leenaert is one of the founders of Ethical Vegetarian Alternative, or EVA, which is a Belgian organisation that advocates the consumption of plant foods instead of animals.

Tobias founded the Center for Effective Vegan Advocacy, CEVA, with Melanie Joy, who you might know as the author of Why we Love Dogs, Eat Pigs and Wear Cows. CEVA aims to increase the impact of vegan advocacy worldwide.

I first heard about Tobias through his work on the Vegan Strategist, a blog where he talks about effect animal advocacy. He is also working on a book on vegan strategy and communication, and gives talks around the world.

Tobias and I chatted about the effectiveness and role for different types of animal advocacy.

An open letter on industrial animal farming

I’m proud to join Scott Weathers, Sophie Hermanns, Mark Bittman and 200+ expert signatories (read: very impressive people) to ask the World Health Organization (WHO) to reduce factory farming.

If you care about any of the following issues; animal suffering, climate change, environmental degradation, antibiotic resistance or global health, please add your signature (https://openletteranimalfarming.com/).

Check out Scott, Sophie and Mark’s op-ed in the New York Times here, Scott and Sophie’s note in The Lancet here, and the original letter here.

If the new WHO Director General takes a strong stance on factory farming, that would be a positive for human and non-human animals in so many ways. Congratulations to Scott and Sophie for what I’m sure will be a highly impactful initiative. I’d also just like to take this moment to remind you how easy it can be to influence things, including high profile individuals and organisations (I’ve written about this here). You can and must take action.
