The U.S. pet industry is now a $43 billion-per-year behemoth, author Michael Schaffer reports in his upcoming book, One Nation Under Dog: Adventures in the New World of Prozac-Popping Puppies, Dog-Park Politics, and Organic Pet Food. That's more than double what we spent on pets 15 years ago. Since ecofriendly pet products and services fetch only $1 billion of the transactions, Americans would have to harness the power of a whole lot of hamster wheels to make up for Rover's and Fluffy's environmental pawprints.
