Farming animals for meat has a massive environmental impact, both in terms of land use and carbon emissions. But in order for people to eat less meat, they need to be excited about the alternatives. Around the world, people are coming up with ingenious meat replacements that look, taste and smell more like the real thing than ever. In Switzerland, we visit the perfume company that’s now turned its hand to perfecting the flavour in veggie burgers. And in Nigeria we meet the entrepreneur who has devised an alternative to beef and chicken that he hopes will appeal to West African tastes. Plus, we speak to the start-up in Israel that’s making kosher veggie ‘meat’ using a 3D printer.
