Christmas seems like a fitting time to reflect on this preface from Old MacDonalds Factory Farm by C. David Coates.
"Isn't man an amazing animal? He kills wildlife by the millions in order to protect his domestic animals and their feed. Then he kills domestic animals by the billions and eats them. This in turn kills man by the millions, because eating all those animals leads to degenerative-and fatal-health conditions like heart disease, kidney disease, and cancer. So then man tortures and kills millions more animals to look for cures for these disease. Elsewhere, millions of other human beings are being killed by hunger and malnutrition because food they could eat is being used to fatten domestic animals. Meanwhile, some people are dying of sad laughter at the absurdity of man, who kills so easily and so violently, and once a year sends out cards praying for "Peace on Earth."
