This planet saving advice is explained in the book: "Time to Eat the Dog: The Real Guide to Sustainable Living". The author, Robert Vale, says:
"There are no recipes in the book. We're not actually saying it is time to eat the dog. "We're just saying that we need to think about and know the (ecological) impact of some of the things we do and that we take for granted. "Once you see where cats and dogs fit in your overall balance of things, you might decide to have the cat but not also to have the two cars and the three bathrooms and be a meat-eater yourself."You know what's coming next don't you? I can just imagine Gordon Brown salivating over his new cat and dog tax.
