I just listened to a podcast a few days ago (cant remember the episode) that spoke about how chicken rarely eaten until the leave it to beaver nuclear family generation. Too much work for too little reward until the age of widespread 100% antibiotic intoxication of the flock, growth hormone, and so on. Kinda like hunters who hunt wild turkeys and come out with a couple small breasts perhaps enough for a person or two at most yet we've created these "birds" that are so insanely out of the norm, can barely walk, and so on, so we can have these buttery bronze betty crocker, june cleaver, turkey dinners to photograph all glistening crispy.
All the while, MS, ALS, Cancer, IBS, C-dif, all industrial age diseases that never existed prior-to... and many many more.
