We were promised a panacea for the climate crisis and a way to save our food system. So why is nobody firing up the chicken vats? I went to find out On 5 August 2013, a man and a woman ate a burger. Not just any burger: a world-historic burger, made from cattle cells grown in a laboratory by Mark Post , a professor of vascular physiology at Maastricht University in the Netherlands. The burger had taken two years to produce and cost €250,000 (about £210,000 at the time), money furnished by the Google co-founder Sergey Brin. Now it was being tasted in public for the first time at Riverside Studios in London, at an event attended by 200 members of the press and livestreamed to thousands. To make this particular burger, Post had extracted stem cells from the shoulder muscle of a living cow, then cultivated them in plastic containers filled with a nutrient-rich supplement called foetal bovine serum, which is derived from cow foetuses. The cells eventually became 20,000 strands of tissue, which in turn became a single 140g patty. Post believed that beef produced this way had the potential to dramatically reduce greenhouse-gas emissions and slow the climate crisis. Raising cattle for consumption requires massive amounts of land and water – and massive amounts of feed grown at a high environmental cost. He projected that global demand for meat would soon outstrip our ability to produce it the old-fashioned way, at which point our food systems would become unsustainable. But that didn’t have to mean a mass recalibration of our consumption habits or a global shift away from red meat. Post and his team had found another way. Continue reading...
