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.

      And who is going to enforce that? How? Crippling economic sanctions on countries that are already at desperation levels of poverty? Invasion? Recolonialization?

      The surest way to drop the birthrate in poor countries, proven to work time and time again, is to raise the standard of living. Richer people have fewer children - it holds true for every level of "rich" outside of the multimillionaire class. Children are an important resource to subsistence farmers and it's natural to have many of them when there is a high likelihood that many of them will not survive to adulthood (even though, in aggregate, many do).

      Children are an enjoyable burden to urban and middle class people - when women work outside the home, there is a huge incentive to have fewer children.

      The down side, of course, is that richer people use more resources, but we can work on that from a technology perspective. But if you want fewer people, make them rich(er).

      All true, but modern pet foods can provide the nutrients without the high meat content. And the other stuff like fruit, gravy and jelly just provide some extra volume and flavour/smell. Keep in mind that modern meat has a lot more nutrients than what those animals would eat in the wild too.

      Obviously we want pets to keep eating meat, it's good for them. I was just suggesting that the reason why it's becoming a problem in terms of emissions now could be due to the changing nature of pet diets, which are generally designed to appeal to pet owners as the primary consideration. Maybe they can be designed to be more sustainable and still provide a good diet.

      At the very least you should ensure that your cat's diet is fortified with Taurine. Much like humans need to eat fruit and veg in order to avoid scurvy, cats need meat and fish in order to get Taurine. (Cats produce their own vitamin C so do not need it in their diet. Ditto for humans and Taurine)

      I'm surprised that your cat "loves fruit and vegetables." That might indicate that it's a very successful hunter and is getting plenty of fresh meat from birds and small mammals. Whether that is a bad thing probably depends on the environment that you live in.
