Growing meat, fish, and animal products from cells rather than whole animals — the most transformative potential technology for ending factory farming
Meat grown from animal muscle cells in bioreactors. Cells are taken from a biopsy of a living animal (without killing it), then proliferated in a nutrient medium and formed into a meat-like structure using scaffolding. Currently approved for sale in Singapore and the USA (limited). Companies include UPSIDE Foods, Good Meat, and dozens of others globally.
Animal welfare impact: If scaled, could eliminate the need to kill animals for meat — the most direct possible welfare benefit.
Using microorganisms (yeast, bacteria) programmed with animal genes to produce specific animal proteins — casein, whey, egg white, lactoferrin — without the animal. These proteins can then be used in products functionally identical to dairy and eggs.
Animal welfare impact: Dairy and egg production involve significant animal welfare issues. Replacing these with fermentation-produced proteins eliminates those issues entirely.
Growing fish and shellfish from cells — bluefin tuna, salmon, shrimp, lobster. Given the enormous scale of aquaculture welfare problems (100+ billion fish farmed annually), cultivated seafood has enormous welfare potential. Companies including Wildtype (salmon) and New Wave Foods (shrimp) are developing products.
Producing dairy proteins (casein, whey) through precision fermentation, then combining with plant-based fats to create dairy products (cheese, yogurt, ice cream) that are molecularly identical to animal dairy. Perfect Day has commercialized fermentation-produced whey; multiple companies are developing animal-free cheese.
Farming insects (black soldier fly, mealworms, crickets) for protein is more efficient and potentially lower-welfare-impact than farming vertebrates. Insects likely have lower sentience than mammals and birds. Insect protein can replace fishmeal in aquaculture and pet food — reducing pressure on wild fish.
Growing fungi for food (Quorn mycoprotein, tempeh) is highly efficient and provides high protein. Fungi are not sentient and do not suffer, making fungal protein one of the cleanest options from a welfare perspective. Significant scaling potential remains untapped.
The welfare case for cellular agriculture is compelling because it addresses the root cause of most animal suffering: the economic incentive to produce cheap animal products at scale using intensive methods. Current alternatives (welfare improvements, plant-based transition) work with or around this incentive. Cellular agriculture potentially removes the incentive entirely — if cultivated meat is cheaper than conventional meat, factory farming becomes economically unviable.
Key welfare benefits if cellular agriculture scales successfully:
The first lab-grown burger cost $330,000 in 2013. Costs have fallen dramatically but are still many times higher than conventional meat. Reaching price parity requires major advances in growth media (especially serum-free media), bioreactor efficiency, and scale.
Growing thin sheets of cells is relatively easy; growing thick, structured meat with fat marbling, fiber alignment, and appropriate texture at food-service volumes is enormously challenging. Scaffold technology and bioreactor design need significant advancement.
Novel foods require regulatory approval. The US FDA/USDA pathway has been established; the EU pathway is more complex. Regulatory timelines and requirements vary globally and create significant market uncertainty.
"Yuck factor" responses — labeling cultivated meat as "unnatural" or "lab-grown" — create consumer resistance that isn't easily overcome with information. Building consumer trust requires authentic engagement and time.
Conventional meat industry lobbying has led to legislative bans on cultivated meat labeling in some US states. The political battle over the terminology and legality of cultivated meat is ongoing and significant.
Current cultivated meat production is energy-intensive. Without decarbonized electricity, the climate benefit over conventional meat is uncertain. Pairing cellular agriculture with renewable energy is essential for its environmental promise.
Major animal welfare organizations including The Humane Society, GFI (Good Food Institute), and others have made supporting cellular agriculture a strategic priority — recognizing it as potentially the most transformative long-term intervention for animal welfare. GFI's open-source research model has accelerated the field significantly. For donors interested in maximum animal welfare impact, supporting cellular agriculture research and advocacy represents one of the most leveraged investments available.
