Showing people where their meat comes isn’t going to reduce the demand in my opinion. I personally believe people should know where their food comes from as it reduces waste and garners introspection about our role in the planet and ecosystem.
I’m Greek American and lamb on the spit is a cultural tradition on Easter. As a kid, it was very weird for my American friends to pick food directly off of a carcass but so many told me over the years it was an unforgettable experience. My uncle once took me to the farm in Georgia where he got the lamb, handed me a large knife and asked me to slit its throat, I was 13 at the time. I couldn’t do it, I cried and watched him do it. I will never forget that. To this day I have a profound love and appreciation of animals, especially lambs. I still eat them. The two ideas for me are not conflicted to me. The only thing I abhor when it comes to meat is wastefulness.
