Cats and Dogs Contribute Significantly To Climate Change, Says UCLA Study (patch.com)
New submitter Zorro shares a report from Patch.com: When it comes to global warming, Fido and Fluffy are part of the problem, a new study by UCLA indicates. Pet ownership in the United States creates about 64 million tons of carbon dioxide a year, UCLA researchers found. That's the equivalent of driving 13.6 million cars for a year. The problem lies with the meat-filled diets of kitties and pooches, according to the study by UCLA geography professor Gregory Okin. Dogs and cats are responsible for 25 to 30 percent of the impacts of meat production in the United States, said Orkin. Compared to a plant-based diet, meat production "requires more energy, land and water and has greater environmental consequences in terms of erosion, pesticides and waste," the study found. And what goes in, must come out. In terms of waste, Okin noted, feeding pets also leads to about 5.1 million tons of feces every year, roughly equivalent to the total trash production of Massachusetts. The study has been published in the journal PLOS One.
A brief check suggests the total CO2 generation of the US is around 5.3 Billion metric tons, which would mean cats and dogs account for 1.2% of the total CO2 generated by the US.
Cats are obligate carnivores, they have to eat meat because they need the ready nutrients only meat can provide.
Dogs have a higher tolerance for carbohydrates, but really, this is an accident of domestication. In any wild setting, all canine species would eat a diet almost entirely of meat because that's what's available. The occasional browsing of grasses and plants may have some digestive benefit for canines but almost no caloric value. Their caloric intake would be animal flesh.

Not true. Dogs are not obligate carnivores. Even wolves routinely supplement their diet with fruits and vegetables in the wild.

Also not true. All wolf subspecies (including dogs, coyotes, dingoes) have an evolutionary preference for meat but will voluntarily eat vegetation in substantial amounts and if necessary can live without meat indefinitely. The Maned Wolf has a diet that is approximately 50% vegetation. With certain exceptions most of what you eat is also readily digestible by your dog too. Dogs are omnivores in actuality.
