WELLINGTON, New Zealand, Dec. 23 (UPI) -- One medium-sized dog produces more greenhouse gas than a Toyota Land Cruiser, New Zealand scientists Robert and Brenda Vale say in a new book.
In "Time to Eat the Dog, the Real Guide to Sustainable Living," the Vales analyzed the ingredients of pet food and how much each pet eats to determine the size of their carbon footprint, a term used to express a total amount of greenhouse gas emissions.
