Lab-grown meat may be better for livestock, but not necessarily for the environment
BBC Science Focus
|October 2024
The move to put alternative protein on our plates is gathering pace but there are still questions to answer
-

On my morning walk with the dog, my path takes me past a field where a small herd of cattle grazes. I usually pause there, partly because my dog is utterly fascinated by cows, and partly because it's a pleasingly bucolic scene.
This is what I picture when I think of livestock farming: cows or sheep wandering around munching grass in a field. Then, like a lot of us who don't work in farming or meat production, I probably don't dwell as much as I should on what happens between the grazing animals and the meat we see on the supermarket shelves.
But there's a burgeoning meat-production industry that looks very different from this, which is set to offer us an innovative alternative using science: meat grown not in an animal, but cultured from a single cell, in a vessel inside an industrial production facility.
I'm curious to try it. And if there's a way I can indulge my appetite for meatballs and sausages without the need for an animal to be slaughtered, I'm keen to explore it.
But lab-grown-meat companies are already making environmental claims that have yet to be borne out by evidence.
