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.

      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).

    (Well for now. By the time the "million-dollar-bugger" process can be perfected and be scaled industrially, they will be also able to eat food that was grown in a VAT).

    Humans have a very variable diet,
    - ranging from only eating plants (lots of traditionnally mostly-vegan diest accross culture + the current latest "vegan trend") as long as you compensate for the few amino acids that some plant lack (basically : don't only eat green leaf salad, eat legume too)
    - all the way to nearly as meat-centric as a cat (happens in some traditionnal diet in most arid regions) as long as you pay attention to get enough vitamins and micronutrients.

    - the former (plant) tend to be rather on the lower range of CO2 production (most of the CO2 is basically produced by the farmer that make your food, by transport, etc.) and varies mostly depending on the production methods and the transport distance (eating local foods lower significantly energy requirement) (eating plants that don't need to be grown in complex industrial greenhouses to compensate for bad local environment also helps).

    - the later (mostly meat) will be more or less the same range of CO2 as cats. Because you need to constantly grow plants (see above mention) to get enough food to feed the meat-producing animal, until that animal is big enough to provide enough meat, at which point you butcher it for meat. Various animal species will produce more or less CO2 (chicken - i think, i might remember wrong - require less food than beef), transport wil have a huge impact.

    In short :
    - A: sun -> plant -> transport -> food in your plate
    - B: sun -> plant -> transport -> forage -> animal -> transport -> food in your plate (or in kitty's bowl)

    Method B has more steps and loses more energy at each inefficient step.

    Hence the interests in method to grow meat in a vat, the same way you could grow algae (cf. million-dollar-burger) :
    - it has the potential to be much more efficient by short cutting the extra steps
    (In addition to being less cruel toward an algae-like culture vs. living animals, which is beside the point of this discussion)

Not to mention their food is also often largely plant-based, and the meat used is often such a low grade that it wouldn't be fed to humans.. I don't know if those numbers add up and they're quite the impact that's claimed.

    Yeah, move all humans & animals to Mars, so that only plants are left on earth. Between photosynthesis & respiration, they'll maintain the climate balance. In the meantime, on Mars, since there is no oxygen, people & animals won't create more carbon dioxide. That way, Mars doesn't get warmed up either, even though it could use it

  29. Living things do not change CO2 levels by Solandri · · Score: 2

    Pets emit CO2, plants absorb CO2 to form cellulose, cows eat cellulose, pets eat cows. The only way you can change CO2 levels via this cycle is if the ratio of CO2 consumers (plants) to CO2 emitters (animals) changes appreciably. It's self-stabilizing because if excess CO2 is emitted, it encourages more plant growth. If CO2 levels drop, it discourages plant growth.

    Climate change due to CO2 happens because we're digging up carbon which is buried deep underground, converting it to CO2 by burning it, and releasing it into the atmosphere. This is increasing atmospheric CO2 levels far faster than new plants can remove it (and even if they remove it, it mostly gets released again as the dead plant is decomposes or is eaten). That buried carbon (oil, coal, gas) comes from ancient plants which died and were buried. Hence the term "fossil" fuels. They removed the CO2 from an atmosphere which had almost no oxygen and was very high in CO2, eventually converting it into the (relatively) oxygen-rich atmosphere we enjoy today. So burning fossil fuels drives the atmosphere back towards that ancient state where only plants could live and animals couldn't.

    This whole "study" is part of a disturbing trend I'm seeing where people (either deliberately or ignorantly) analyze only part of the system to try to make something look good or bad, instead of properly analyzing the entire system. e.g. So-called zero emissions vehicles, which aren't really zero emissions. They just move the emissions from the tailpipe to the power plant which generates the electricity or hydrogen. Since their overall energy efficiency is only about 30% better than that of ICE vehicles (their operating cost is lower because coal is about 10x cheaper than gasoline per MJ), they're still causing a lot of CO2 emissions as opposed to carpooling or public transportation.

  30. byrd poop by slew · · Score: 3, Informative

    Been-there done-that. You know there have been wars fought over byrd poop. Mostly because byrd poop (aka guano) was very helpful in making bombs (as well as being fertilizer for food)

    Fortunately (unfortunately?), we discovered how to industrialize a process to fix nitrogen straight from the air (haber-bosch), so we don't need to annex and dig up islands for byrd poop anymore. We just need to burn natural gas...

  31. Re:equivalent to the trash production of Massachus by hey! · · Score: 2

    I actually AM from Massachusetts, and having worked all around the country it's not really a mystery to me. It's educational attainment. Over 40% of residents here have a bachelor's degree, and 18% have a graduate degree. We also have -- going by test scores -- the best K-12 schools. Consequently a lot of things just work better here because people are somewhat better prepared for their jobs.

    Which is not to say an educated person in Massachusetts is better than an educated person in Arkansas. Or even that an educated person is somehow *morally* better than an uneducated one. But things do run better when a higher proportion of workers can read instructions and do basic math.

    In recent decades, cats and dogs have been the only exposure people - especially children - get to non-human animals on a regular basic.

    Even sadder, fewer and fewer children have any exposure to non-human animals. One big reason for this is that more and more children are being over scheduled into organised activities, leaving too little time to engage with a pet.

    Call us "crazy cat people" if you insist, My girlfriend, daughter and I feel more human for having our feline friends. And most of our relatives and (human) friends have similar feelings about their pets.
