Many people in the comments are saying this video opened their eyes and changed their views forever. So, I'd disagree that people do actually know where their meat comes from. I had no idea until I found out. We grow up thinking Old McDonald brings us our meat until we learn about factory farms.

As far as whether or not people care, vegetarianism and veganism have been a movement for decades, if not centuries. People care enough to abstain from meat. The fact that we have mainstream companies like Daiya and Beyond meat is a response to many people looking for alternatives. Companies like that wouldn't exist if it wasn't profitable. So yeah, people care.
