Book excerpt: Did you know that a quarter of all the meat consumed in the United States is eaten by our pets? That's the equivalent to the amount devoured by 26 million Americans, and it makes U.S. cats and dogs equal to the fifth largest country in terms of animal protein consumption. Yet the impact pet food has on the environment and climate change, how healthy or necessary it is for our animal companions, or how it impacts the welfare of the farmed animals who become that food are barely known or ignored--even by animal lovers! The Clean Pet Food Revolution lifts the lid on the current pet food industry: its claims of what constitutes a "natural" diet for pets, its shocking record on animal welfare, and its devastating effect on the environment and climate change. The book explodes myths about "grain-free" diets, protein intake, and what our pets "want." Finally, it details the many exciting scientific developments in alternative proteins--whether from plants, fungi, insects, or cell-based meat products--that promise not only to completely change what we feed our cats and dogs but to reduce greenhouse gas emissions, end farmed-animal slaughter, and make our pets healthier. Written by specialists in veterinary science, biotech, and animal welfare, The Clean Pet Food Revolution is a thoroughly researched and compellingly written excoriation of an unsustainable present and a fascinating glimpse of future possibilities.
