The world population is expected to reach 9.6 billion people by 2050, the middle class is growing, and meat consumption is expected to increase by 70%. Meat production requires a great amount of resources: 34 kgs of feed are necessary to produce 1 kg of meat, the same kg of meat requires ca. 14000 l of water to be produced. In the last decades, more than 25 companies have been founded in order to find a solution for the meat production problem and arrive at a sustainable way of eating meat. The two major options are plant-based meat and clean-meat, a lab-produced meat.
