If we stopped the mass production of meat, it would become so expensive that you would probably stop buying it altogetther. Low-cost lab meat could be the answer to this. You don't need to worry about harmful chemicals, the meat is grown in a solution of nutrients that are completely healthy. The name 'lab' meat is a bit misleading, it just means it was developed in a lab, but it will be produced in a factory like every other processed food. Maybe they should call it 'cultured' meat or something.
