No matter which side of the go-vegetarian debate you’re on, there’s no arguing that the current methods of animal farming are wholly unsustainable. Animal farming currently takes up nearly a third of the earth’s land mass, the widespread mistreatment of animals has been widely reported, and meat production is extremely inefficient. Meanwhile, researchers predict that demand for meat will double over the next 40 years. We want burgers—currently to the tune of $74 billion a year.
Which is why a group of Dutch scientists has spent years developing lab-grown meat, which they recently announced will be ready for an initial taste test by the end of the year. Using bovine fetal cells cultured like bacteria, grown in a vat, and mixed with lab-grown animal fat, the scientists are working to create test tube burgers, sausages, and more, with plans to expand to dairy and other animal products later. Though the associated costs are currently high, the hope is that eventually the technology will feed more people more efficiently—while also reducing environmental, cruelty, and illness issues related to farming—and it’s so far gotten support from several avenues, including private donors and PETA. But do we really want to eat test tube meat?
