The hidden environmental costs of dog and cat food
Gregory Okin is quick to point out that he does not hate dogs and cats. Although he shares his home with neither — he is allergic, so his pets are fish — he thinks it is fine if you do. But if you do, he would like you to consider what their meat-heavy kibble and canned food are doing to the planet.
Okin, a geographer at UCLA, recently did that, and the numbers he crunched led to some astonishing conclusions. America’s 180 million or so Rovers and Fluffies gulp down about 25 percent of all the animal-derived calories consumed in the United States each year, according to Okin’s calculations.
