In his book Tempted and Tried Russell Moore recounts an NPR program about a scientist named Temple Grandin who is researching new ways to gently kill cows. It's an important issue because if the animals experience high stress levels prior to death, hormones get released that lower the meat quality. Thus, Grandin has been exploring how to keep the cattle calm as they are being led to slaughter.

Grandin's research has led to one simple insight: novelty distresses cows. The key is to keep everything in their lives feeling and looking as normal and natural as possible. Russell Moore summarizes Grandin's techniques for gently killing the cows:

Workers shouldn't yell at the cows, [Grandin] said, and they should never use cattle prods, because they are counter-productive and unneeded. If you just keep the cows contented and comfortable, they'll go wherever they're led. Don't surprise them, don't unnerve them, and above all, don't hurt them (well, at least until you slit their throats at the end).

Along the way, [Grandin] devised a new technology that has revolutionized the ways of the big slaughter operations. In this system the cows aren't prodded off the truck but are led, in silence, onto a ramp. They go through a "squeeze chute," a gentle pressure device that mimics a mother's nuzzling touch. The cattle continue down the ramp onto a smoothly curving path. There are no sudden turns. The cows experience the sensation of going home, the same kind of way they've traveled many times before.

As they mosey along the path, they don't even notice when their hooves are no longer touching the ground. A conveyor belt slightly lifts them gently upward, and then … a blunt instrument levels a surgical strike right between the eyes. They're transitioned from livestock to meat, and they're never aware enough to be alarmed by any of it. The pioneer of this technology commends it to the slaughterhouses and affectionately gives it a nickname. [Grandin] calls it "the stairway to heaven."

Moore goes on to warn us about the spiritual forces at work in our lives:

Forces are afoot right now, negotiating how to get you fat enough for consumption and how to get you calmly and without struggle to the cosmic slaughterhouse floor. The easiest life for you will be one in which you don't question these things, a life in which you simply do what seems natural. The ease of it all will seem to be further confirmation that this is the way things ought to be …. You might feel as though your life situation is like progressing up a stairway so perfect it's as though it was designed just for you. And it is. In many ways the more tranquil you feel, the more endangered you are.
