A prime example of this is chicken—an animal Michael says has been re-engineered through breeding and diet to produce the breast meat consumers want. Compared to 50 years ago, chickens are now raised and slaughtered in half the time and grow twice as big.
In one way, Michael says this is a great achievement. "Chicken used to be this special occasion, Sunday night dinner. [It] was the expensive meat," he says. "Now it's the cheap meat."
"But you have to understand there's a price to that, and the price is you can only do it with lots of antibiotics," Michael says. "You give all those antibiotics to your animals, they're not gonna work for you when you need them."
