“Companies, investors will want animal-free protein” describes how companies are developing not only plant-based meat alternatives but actual meat cells grown in bioreactors instead of animals. The latter (1) reduces waste enormously because little if any of the nutrients are used by metabolism, (2) reduces pollution and greenhouse gas emissions (methane), and (3) eliminates animal cruelty issues along with hazardous low-wage meat packing industry jobs. The latter are infamous for repetitive motion injuries.
