What is the life of a cricket worth?
These aren’t the fried tarantulas on a stick peddled to tourists or scorpion lollipops sold as novelties. Rich in protein insect powder can be used in food breads at buns, Pasta and protein bars. Such products are already available in countries like WE, Swiss and Finland.
As an entomologist who studied the potential and promotion of edible insects in new markets, I have seen how much progress has been made in the last decade to normalize the idea of eating insects around the world. Now is the time to assess the ethical aspects insect breeding.
insects for humanity
The main motivation for the growing popularity of edible insects is environmental. Producing 1 kilogram (2.2 pounds) of insect protein requires about 10% of food, water and land used for the same amount of beef production, and releases as little as 1% of the greenhouse gas. Insects have a lower environmental impact even compared to other meat alternatives like dairy, gluten and mycoprotein.
Raising insects on waste greatly increases these benefits. The black soldier flies can be found on agricultural by-products such as vegetable peelings or spent grains. The larvae are then used as food for fish and poultry, waste recycling and reduce dependence on more expensive soymeal and fish foods.
Apart from being big business, insect farms also provide important sources of protein and income for rural households. They can be established inexpensively, with little space, and are a boon to small-scale farmers who lack resources for livestock, while sustainably providing feed and fertilizer.
A good example is the “Insects for Peaceprogram that has helped ex-combatants in post-conflict Colombia to reintegrate. Former soldiers found a livelihood by cultivating black flies, which are used as cattle feed.
Is insect meat cruelty-free?
An added benefit is that insects don’t evoke much empathy. With few exceptions, even vegetarians rarely think twice about squashing mosquitoes, let alone the million agricultural pests killed when growing crops.
Those who care can rest assured that farmed insects live net positive lives, free from fear of predators and starvation. Insect welfare is easy and convenient: although the cramped, hot and dirty environments in factory farms are cruel to vertebrates, they are ideal for insects like mealworms that thrive when crowded. One can imagine that there are not many requirements to set up a cockroach farmalthough his neighbors may disapprove.
Killing insects is another problem.
Recent surveys of UK insect breeders found many are concerned about the pain perception of insects and offer their mini-livestock a “good death”. The most common culling methods used by large-scale insect breeders are freezing or freeze-dryingwith the assumption that cold-blooded insects will fall asleep humanely and never wake up.
While the insects can and does feel physical pain, they probably don’t do it consciously. Invertebrate Neurologist Shelley Adamo notes that many insect behaviors are “incongruouswith the pain felt by mammals, citing reports of insects walking normally on broken legs or mantids mating while their partner eats them alive. Entomologist Craig H Eisemanninfluential critic of the field, “Do insects feel pain?concluded that they lacked too many neurological, chemical and behavioral signs for a painful condition.
Nonetheless, scholars like Eisemann and other advocates agree that insects should be bred and killed. assuming they feel pain. This means that the method of slaughter should be as quick and painless as possible.
Although potentially less painful than boilingbecause extreme heat is known to induce responses to pain in insects, freezing is slow. Shredding is a popular alternative: at their small size, insects can be ground to powder almost instantly, before they feel any pain. Current surveys suggest public perception of spraying is still negative compared to freezing, but insect breeders increasingly regard it as the most human choice.
The low probability that farmed insects will suffer, if they can “suffer” at allcombined with the environmental and social benefits of insect farming, caused the philosopher Chris Meyer pretending that eating insects is not only morally acceptable, but also morally good.
This idea gave rise to the term “vegan.” As pescatarians follow a vegetarian diet but still eat seafood, entovegans willingly eat arthropods, knowing that their diet is both sustainable and ethical.
How much are insect lives worth?
What gives some strict vegans pause is the number of insects involved.
In a 2020 preprint, an animal welfare activist Abraham Rowe calculate that 1 trillion to 1.2 trillion individual insects are grown each year for food and feed, excluding wild-harvested insects. On average, 79 to 94 billion farmed insects are alive on farms around the world every day, compared to only about 22 billion chickensthe most popular meat on Earth.
So what is the value of the life of an insect compared to that of a plant or a bacterium? Awareness capacity is a popular metric for determining whether an organism has moral positioneven if there is disagree on how to measure that.

If one assumes, hypothetically, that insects are 0.1% as susceptible as cows, or that the probability that insects can suffer is 0.1%, then killing 1,000 crickets has a similar ethical footprint as to kill a cow. It may seem generous, yet in its guide”How to answer some ethical objections to entomophagy», philosopher Bob Fisher calculates that one cow produces as much meat as 900,000 crickets.
However, the calculations change when you consider the number of animals dying in agricultural fields: conservative estimates put at least 10 million invertebrates per acre of crops at risk from pesticides, along with thousands of small vertebrates unmistakably aware as mice and rabbits threatened by mechanical harvesters. This calculation adds millions of deaths not only to traditional meat production in feed fields, but to almost every crop grown, including soybeans. To quote biologists Charles Nicol and Sharon Russell“There’s no bloodless veggie burger.”
Fisher calculated that the number of insects killed to produce a plant-based diet or an insect-based diet are almost the same, which means that ento-veganism and veganism are in this sense equivalent. Eating insects raised on organic waste, virtually eliminating the environmental and animal mortality costs of growing the plants, may be the best option of all.
The rise of insect farming means that questions about insect sentience and culling are no longer just philosophical: the well-being of trillions of creatures are at stake.
