I honestly can't tell if he's trying to tell people the truth about pet food--or if he's on a rant about wastefulness and neutering.
He seems awfully sarcastic and facetious to me.
Within it all, he seems VERY determined to let people know exactly what's in that junk. He seems VERY upset about what humans have done to animal life overall.
Maybe he's saying that if we hypocritically don't care about other animals any more than we do, why should we care about dogs and cats?
This mass of otherwise unwanted death is a measure of the animal suffering caused by human activity. Fifty percent of all chickens hatched out for the egg business are unneeded roosters that are discarded. Roughly 75 percent of all cats in shelters are euthanized. Because they were unprofitable, because they were inconvenient, because we made too many of them, they were killed.
The more that I learned about the pet-food business while writing this article, the less significant the cannibalism aspect seemed to me. My initial outrage at feeding dogs to dogs gave way to outrage at dogs being overproduced and dumped in shelters to be killed in the first place. One million deer are killed by vehicles each year. Even the plastic and Styrofoam from wasted grocery store meat that nobody even bothers to unpackage before rendering has come to seem a minor harm compared to the sins of a food system that devotes so much arable land to producing meat - in a world where people still starve to death - that we can’t even get around to eating it all before the expiration date hits.
Yes, it's an ugly way to bring up his point, but he DOES have a point in all that--a point that has nothing to do with pet food, but more a point about the evils of man that get the meat to the rendering plants in the first place.
Perhaps he watched
Soylent Green one too many times?
