The majority of farmed animals killed each year are insects, and this number is only expected to increase. By 2033, it’s estimated that around 5 trillion insects will be slaughtered annually—more than 50 times the number of cows, pigs, chickens, turkeys, and the like currently slaughtered. But insect farming is built on a dark secret: its foundational premises are all lies!

There has been a calculated plot by the insect farming industry to mislead the public. They know that if the public knew the truth about them, they’d never support subsidizing them. The insect farms can only thrive in darkness—shielded from public scrutiny.

Insect farming was promised as an environmentally-friendly alternative to meat. In reality, however, there’s virtually no consumer market for insects, so the insect farming industry mostly feeds insects to farmed animals like chickens and fish. Insect farming is not a competitor of traditional, environmentally-devastating factory-farming—it’s a complementary industry. For this reason, the insect farming industry is on track to be bad for the environment and to increase carbon emissions. A report by the UK government estimates that insect feed fed to animals has 13.5 times the carbon emissions of soy-based alternatives. Further studies have only confirmed this impression. Part of why the industry is so disastrous is that it must use lots of resources and energy feeding insects and keeping them at adequate temperatures to grow.

How does the insect industry challenge such allegations? Well, mostly they ignore them. In the rare cases they address them at all, they make mealy-mouthed (meal-wormy-mouthed???) statements about the importance of sustainability while ignoring the inconvenient facts about their environmental impact. Journalism articles talking about the promises of insect farming uncritically quote the CEO’s of insect companies—a bit like an article about the impact of oil on the environment uncritically quoting the head of an oil company.

They also cite their own life-cycle assessments. Basically, they pay people to analyze their environmental impact, and shockingly discover that they’re great for the environment. It’s no surprise that when an insect company pays someone to analyze their environmental impact, the people paid by the insect industry often find that insect farming is great for the environment—wildly contradicting the results of academic studies. The data from such studies is consistently private so that independent investigators can’t vet it. This would be a bit like big oil doing their own report, and which they cite as evidence of the environmental sustainability of oil. Once again, the insect farming can only pretend to be environmentally friendly by lying and misleading.

It was claimed that the insect industry would be an economically-viable juggernaut—feeding large numbers of people. But in reality, the industry has been embarrassingly floundering because it can’t sustain itself. The largest insect company recently shut down despite half its money coming from federal subsidies, and many of the others are on the verge of bankruptcy.

One detailed report summarized “Through interviews with insect rearing experts we discover that currently the insect industry is not able to offer many economic, environmental or social values.” Insect meal is far more expensive than traditional livestock meal, and that is unlikely to change in the future. The largest Dutch financial newspaper summarized the dismal situation in an article titled How Investors Completely Choked on Edible Insects.

Insect farming was promised to be able to outcompete alternatives. It was never supposed to be propped up indefinitely by taxpayer dollars. In reality, however, it’s strikingly reliant on federal funds. Despite millions of dollars in funding, the insect farming industry can’t seem to be viable.

It was promised as a more humane alternative to traditional meat consumption. But then the insect farms built colossal juggernauts of insect torture. Most industrially farmed animals slaughtered every year are insects. They’re kept in overcrowded crates with no ability to express their natural behaviors. Disease spreads rapidly. They’re killed by being crushed to death, boiled, or microwaved. This often takes minutes or hours. The adult black soldier flies, the most farmed species of farmed insect, are never fed—they’re all killed by being starved to death. And all this comes at a time when more and more research is confirming that black soldier flies feel pain just like larger and more charismatic animals.

The industry has justified this inhumane mass starvation policy by claiming that adult black soldier flies don’t need to eat food. This would come as news to the black soldier flies themselves! Like much of what the industry claims, it is complete fabrication used to justify mass starvation. They cannot eat solid food, but can eat liquid food—and need to eat it to survive. When they don’t, they die in a matter of days. This is just another of the many lies that the insect farming industry needs to fool people into believing to justify their continued existence.

Disease spreads so rapidly in the farms that it’s even a threats to wild insects. Because the industry has limited ability to contain the insects, the disease that run rampant in the farms could spread.

Why are we doing this? Why are we spending millions or billions of dollars of taxpayer funds propping up a failing industry that can’t make a profit on its own. Why are we providing mass subsidies for those hurting the environment and mass torturing insects? Why we we allowing an industry to keep the majority of farmed animals slaughtered each year in hellish conditions—all so that they can provide bougie pet food and overpriced food for farmed insects?

It would be one thing if insect farming were what it was claimed to be. If insects didn’t suffer, if it was an economically viable replacement for environmentally-unfriendly animal products, perhaps these subsidies would be justified. But every one of the claims that insect farming is based on is a lie. It is worse for the environment, worse for animals, a helper rather than competitor of traditional factory farming. Humans are not going to eat the bugs. Farmed fish are.

Can someone in DOGE cut these subsidies? If you know anyone from DOGE, please reach out to them about this! Not eating the bugs seems to be a big thing among conservatives. So why the hell are we subsidizing bug farms, so that your hard-earned tax payer dollars are spent keeping failing bug farms afloat. The industry knows that people are not going to eat bugs, so they must engage in subterfuge—and feed the bugs to farmed animals who you then eat.

I won’t eat the bugs! Probably you won’t eat the bugs! Almost no one wants to eat the bugs! So let’s stop using taxpayer funds to prop up an industry built on a series of lies that have now been conclusively proven false. Reach out to your local representative about this! It’s about time they stopped taking our money to fund an industry built on lies and the corpses of trillions of insects who they starved to death.

(If you want to help out farmed insects, you can give here and here—both are potentially very high impact.)

Relevant news article from today, on a report saying people are unlikely to be willing to eat insects - just thought I'd share: https://www.theguardian.com/environment/2025/jun/25/eating-insects-meat-planet

Executive summary: This impassioned exposé argues that the insect farming industry—widely promoted as sustainable, ethical, and economically viable—is instead environmentally harmful, economically failing, and built on deceptive claims, making its continued public subsidization unjustifiable.

Key points:

  1. Environmental harm: Contrary to industry claims, insect farming may be worse for the environment than soy-based alternatives, with a UK government report estimating 13.5 times the carbon emissions, due to energy-intensive heating and inefficient feed conversion.
  2. Industry deception: Insect companies promote sustainability through self-funded, opaque studies while ignoring or contradicting independent academic research; public-facing narratives are controlled to evade scrutiny.
  3. Economic failure: Despite millions in subsidies, the insect farming sector is economically unsustainable, with major companies collapsing and feed remaining significantly more expensive than traditional options.
  4. Animal welfare concerns: Insects are farmed in cruel, disease-prone environments and killed by starvation, boiling, or crushing, raising moral concerns—especially as evidence grows that insects feel pain.
  5. Misaligned incentives: The industry does not serve a human food market but mainly supplies feed for farmed animals, undermining claims that it’s a substitute for meat consumption.
  6. Call to action: The author urges readers to pressure policymakers (specifically referencing DOGE) to end taxpayer subsidies for insect farms and support organizations focused on insect welfare instead.

Thanks for the post, Matthew! I strongly upvoted it. However, I do not think you mentioned the best case for farming insects, and feeding these to other animals. This will tend to increase cropland, and therefore decrease the number of wild animals, which is beneficial for my best guess that wild animals have negative lives. The effect on wild animals may be larger than those on the farmed insects. I estimate increasing the consumption of shrimp increases the welfare of soil nematodes, mites, and springtails 9.39 times as much as it decreases the welfare of shrimp for feed crops replacing temperate grasslands, savannas, and shrublands (assuming shrimp requires 2.97 m²-year/food-kg).

Strong downvoted again. This is an article about "The lies of big bug" and how the bug industry is misleading people about the good they are doing, and also their financial viability as a business. I don't think your comment addresses the main points of the article.

If this was a post which focused on questions and tradeoffs between insect welfare and wild animal welfare than I think your comment would be very relevant.

One of the main points of the article is that insect farming is bad for insect welfare, so Vasco's comment seems on-topic enough for me. Maybe the link to that part of the argument could have been stated more clearly.

Maybe it seems repetitive if you see such comments a lot, but then it suggests that main posts are repeatedly neglecting the argument. Perhaps it would be better for main posts just to point out that this argument exists in their caveats and link to a discussion somewhere. If it might change the whole sign of whether something is good or bad, it seems like it should be at least mentioned.

For people like me who only come to read the occasional post, it does feel useful to be reminded of these other perspectives.

Thanks, Nick. I also upvoted your comment again. The post seems to be strongly suggesting that farming insects is harmful, so I think my comment pointing the main way I believe it could be beneficial is appropriate.

Yes I would go even further to say it assumes insect farming is harmful, but I don't think that's a good enough justification for a comment challenging that underlying assumption - as discussing the assumption isn't the purpose of the post. I would think the same thing about posting an argument for the "meat-eating problem" on a given global health post, which in a similar vein assumes that saving human lives is good. 

I think the best place for these discussions is on posts which specifically address that issue, or events like the Animal welfare vs. Global health debate week where these questions are ever bubbling up.

I don't think commenting in this way on every (or a random-ish selection) of post that assumes insect farming is harmful is a helpful way to operate and promote healthy discussion on the forum, but I think its reasonable to disagree with me here as well. Maybe the OP might even disagree!

I agree it would not make sense to comment this way in every post or a random selection of posts. However, Matthew (the author of the post) is one of the people I know most sympathetic about considering effects on wild animals, and also has the best guess that wild animals have negative lives (like I do), which makes farming insects tendentially beneficial to wild animals.

Fair (didn't know that context) - if @Bentham's Bulldog agrees I'll withdraw the downvote.

For reference, Matthew recommended donating to GiveWell to decrease the number of wild animals.

It sounds like the benefit under this argument comes from reducing wild land. You could do that without causing lots of other insects (or other farmed animals) to suffer e.g. grow crops and burn them for energy instead, or manage the land to keep insect numbers down. So I don't find this argument very persuasive that we should think of this as a positive benefit to intensive farming of insects or other animals, even supposing that insects (or other animals) have overall negative lives in the wild. Perhaps this isn't the right location to discuss this in depth, though.

Thanks for the comment! The benefits from increasing insect farming come from replacing with cropland biomes which have less nematodes, mites, and springtails per unit area, and therefore decreasing the animal-years of these soil animals. I agree there are more cost-effective ways of achieving this. I have some cost-effectiveness estimates here. However, (counterfactually) decreasing the animal-years of farmed insects would still be harmful if it increased the suffering of wild animals more than it decreased the suffering of farmed animals. Here is an extreme somewhat silly analogy which might help. There are more cost-effective ways of increasing human welfare than giving cash to people in extreme poverty, but millionaires slealing cash from people in extreme poverty is still harmful in the sense of decreasing human welfare.

I think there are at least two relevant aspects here - the impact of ceasing insect farming and the question of which policies should be supported.

On the impact of ceasing insect farming, a consideration that it's not clear to me has been taken into account is what the land would be used for if not for growing food for insects - it wouldn't necessarily become wild, rather it could be used to grow other crops, and thereby have no large effect on wild animal welfare. Rates of deforestation seem to indicate there is plenty of demand for arable land. Also, biofuels seem to be being held back by land availability and worries over these competing with food crops, again potentially acting as a strong source of demand for land. So the effect of removing one source of demand seems complex, and it seems like it may just result in substitution by another type of farming. The marginal effect may be to affect deforestation rates - but to what degree these are affected by changes in demand for crops is unclear to me.

Re the question of support this gives for insect farming, even if it had an overall positive effect, it's not clear it should be advocated if there would be other uses for that land that would be better e.g. growing biofuels. So it doesn't clearly make a "case" for defending insect farming.

More generally, if an action A involves doing P and Q, where P is good and Q is bad, but there are ways of doing P that don't involve the harm of Q, then the implication would seem to be to advocate one of those other ways of doing P and not to defend A - in this case P = farming crops and Q = farming insects.

Thanks for the clarifications! I seem to agree with all your points.

This is a linkpost for a paper I wrote recently, “Endogenous Growth and Excess Variety”, along with a summary. Two schools in growth theory Roughly speaking: In Romer’s (1990) growth model, output per person is interpreted as an economy’s level of “technology”, and the economic growth rate—the growth rate of “real GDP” per person—is proportional to the amount of R&D being done. As Jones (1995) pointed out, populations have grown greatly over the last century, and the proportion of people doing research (and the proportion of GDP spent on research) has grown even more quickly, yet the economic growth rate has not risen. Growth theorists have mainly taken two approaches to reconciling [research] population growth with constant economic growth. “Semi-endogenous” growth models (introduced by Jones (1995)) posit that, as the technological frontier advances, further advances get more difficult. Growth in the number of researchers, and ultimately (if research is not automated) population growth, is therefore necessary to sustain economic growth. “Second-wave endogenous” (I’ll write “SWE”) growth models posit instead that technology grows exponentially with a constant or with a growing population. The idea is that process efficiency—the quantity of a given good producible with given labor and/or capital inputs—grows exponentially with constant research effort, as in a first-wave endogenous model; but when population grows, we develop more goods, leaving research effort per good fixed. (We do this, in the model, because each innovator needs a monopoly on his or her invention in order to compensate for the costs of developing it.) Improvements in process efficiency are called “vertical innovations” and increases in good variety are called “horizontal innovations”. Variety is desirable, so the one-off increase in variety produced by an increase to the population size increases real GDP, but it does not increase the growth rate. Likewise exponential population growth raise

TLDR When we look across all jobs globally, many of us in the EA community occupy positions that would rank in the 99.9th percentile or higher by our own preferences within jobs that we could plausibly get.[1] Whether you work at an EA-aligned organization, hold a high-impact role elsewhere, or have a well-compensated position which allows you to make significant high effectiveness donations, your job situation is likely extraordinarily fortunate and high impact by global standards. This career conversations week, it's worth reflecting on this and considering how we can make the most of these opportunities. Intro I think job choice is one of the great advantages of development. Before the industrial revolution, nearly everyone had to be a hunter-gatherer or a farmer, and they typically didn’t get a choice between those. Now there is typically some choice in low income countries, and typically a lot of choice in high income countries. This already suggests that having a job in your preferred field puts you in a high percentile of job choice. But for many in the EA community, the situation is even more fortunate. The Mathematics of Job Preference If you work at an EA-aligned organization and that is your top preference, you occupy an extraordinarily rare position. There are perhaps a few thousand such positions globally, out of the world's several billion jobs. Simple division suggests this puts you in roughly the 99.9999th percentile of job preference. Even if you don't work directly for an EA organization but have secured: * A job allowing significant donations * A position with direct positive impact aligned with your values * Work that combines your skills, interests, and preferred location You likely still occupy a position in the 99.9th percentile or higher of global job preference matching. Even without the impact perspective, if you are working in your preferred field and preferred country, that may put you in the 99.9th percentile of job preference

Sometimes working on animal issues feels like an uphill battle, with alternative protein losing its trendy status with VCs, corporate campaigns hitting blocks in enforcement and veganism being stuck at the same percentage it's been for decades. However, despite these things I personally am more optimistic about the animal movement than I have ever been (despite following the movement for 10+ years). What gives? At AIM we think a lot about the ingredients of a good charity (talent, funding and idea) and more and more recently I have been thinking about the ingredients of a good movement or ecosystem that I think has a couple of extra ingredients (culture and infrastructure). I think on approximately four-fifths of these prerequisites the animal movement is at all-time highs. And like betting on a charity before it launches, I am far more confident that a movement that has these ingredients will lead to long-term impact than I am relying on, e.g., plant-based proteins trending for climate reasons. Culture The culture of the animal movement in the past has been up and down. It has always been full of highly dedicated people in a way that is rare across other movements, but it also had infighting, ideological purity and a high level of day-to-day drama. Overall this made me a bit cautious about recommending it as a place to spend time even when someone was sold on ending factory farming. But over the last few years professionalization has happened, differences have been put aside to focus on higher goals and the drama overall has gone down a lot. This was perhaps best embodied by my favorite opening talk at a conference ever (AVA 2025) where Wayne and Lewis, leaders with very different historical approaches to helping animals, were able to share lessons, have a friendly debate and drive home the message of how similar our goals really are. This would have been nearly unthinkable decades ago (and in fact resulted in shouting matches when it was attempted). But the cult
