Machines take a lot of handwork out of what everyone used to do anyway.
Scrapple, headcheese, sausage, the various organ”wursts”, etc.
Feeding more people off less is a reasonable goal. The dogs can still eat just fine off the bones and fat , like they did 1000 years ago.

Absolutely! People don’t realize how, not so very long ago, people made use of the “manky bits” themselves because they couldn’t afford *not* to use them. In a lot of countries, people still can’t afford to waste things like offal, blood (Filipino dinuaguan stew, etc.).
