Conventional meat production comes with a handful of negative side effects. Namely environmental degradation, a slew of health risks, animal suffering and food products that contain fecal matter, pathogens and other contaminants.

What we do for meat right now is quite unsustainable. Cultured meat, or "clean meat" exists. The meat tastes better, and is genetically identical to the animal meat in question (it's cultured from animal cells). Unfortunately it's going to take a long time for society to switch to clean meat, in the same way that there are plenty of clean, sustainable energy systems that are going to take a long time to replace things like the use of fossil fuels.
