40% huh? Where have I heard that percentage before…
Capital will literally destroy this planet in order to “profit” from cars and carnism.
To clarify what this user is referring to, Poore & Nemecek 2018 is a recent, widely cited meta-analysis covering over 1530 studies assessing the environmental impacts of food. It’s published in one of the world’s top academic journals – Science – and authored by Dr. Joseph Poore, the director of the University of Oxford’s food sustainability program, and Dr. Tomas Nemecek, an expert on agroecology and life cycle assessments from the Zurich University of Applied Sciences.
They somehow constantly appear like a spectre whenever this study gets brought up to try to spread FUD about it through vague and unsubstantiated nonsense. They do this because it’s extremely compelling, effectively unambiguous evidence that many animal products such as dairy are abysmal for the climate (“because it’s devastating to my case!”). I highly encourage anyone interested to read it for themselves. The article is paywalled, but Dr. Poore hosts it for free through their personal website, so you don’t have to take either of our words for it.
Edit: the paper they quote (but conspicuously don’t link to) below to try to refute this methodology is itself a meta-analysis of 369 LCA studies in the same vein as Poore & Nemecek. I can’t; my sides are in orbit. Edit 2: For anyone wanting to read it in full, Lancaster University hosts Clune, Crossin & Verghese 2015 legally and for free as well, so again, you don’t have to take either of our words for it.
it is not compelling, because the LCA references explicitly say that they cannot be combined with other LCA studies. poore-nemecek ignores this guidance and draws hyperbolic conclusions.
First, it is often cited that LCA results should not be compared (Desjardins et al., 2012; Foster et al., 2006; McAuliffe et al., 2016; Röös et al., 2013) due to variation in methodology choices, functional units, as well as temporal and regional differences2. Second, no single comprehensive review was identified that adequately covers the breadth of fresh foods available to consumers and caterers. As Helle et al. (2013, p.12643) state ‘data availability and quality remain primary obstacles in diet-level environmental impact assessment’, while Pulkkinen et al. (2015) calls for the creation of a database that communicates data quality, uncertainty and variability to reliably differentiate between the GWP of food types. Previous studies have compiled LCA data to compare different foods (e.g. Audsley et al., 2009; Berners-Lee et al., 2012; Bradbear and Friel, 2011; de Vries and de Boer, 2010; Foster et al., 2006; Nijdam et al., 2012; Sonesson et al., 2010; Roy et al., 2009). While these are useful attempts, the identified studies are inadequate in the coverage of fresh foods available. Environmental Product Declarations (EPDs) attempt to inform consumers of the environmental impacts (carbon, water and ecological footprint) of specific foods, however they also fall short in breadth of items covered at present. The most comprehensive attempt at carbon footprint labelling was performed by Tesco (2012), however failed to label key categories such as fresh fish, pork, lamb or beef before finishing in 2012 due to the scale of the labelling scheme and a lack of participation from other retailers (Head et al., 2013). Third, studies that do compare results may often present singular figures. Peters et al. (2010) and Röös et al. (2011) argue that a range of impacts should be reported from LCA’s to better represent the variety of environmental impacts, as opposed to a singular figure. Finally, there is a lack of synthesised open access LCA data in the public domain available to consumers to inform decision-making.
Well, yes, but many regions that are going to have water supply issues aren’t near the animal ag farms. Closing a dairy farm in New Hampshire isn’t going to help things in central Africa. The bigger culprit is Climate Change bringing dry air flows to areas that previously had more humidity and precipitation.
Well, the Danes are about to get super rich. Guess they were right to keep hold of Greenland.
Much like Canada though, I don’t think they have resources to defend their water
Dont worry, there will be a considerable drop in demand due to artificial circumstances. So I wouldn’t worry if you survive what is to come.
Also not an issue if you’re in the rich part of the world, or just one that has a lot of water. Fortunately I don’t think water is gonna be what makes Russia invade, don’t know what their supply looks like but I can’t imagine it’s not enough.
Russia has the largest freshwater lake by volume, Lake Baikal, so they aren’t likely to invade anyone because of their drinking water needs. Especially because Ukraine has been instrumental in reducing their need of fresh water.
It’s a big lake but a bigger country. I don’t think Russia will be the first to have big water issues. Rather, I would look to Mexico City, Panama, Arizona, Nevada, California.
But I need it to cool my AI powered rule 34 service.
I’m so glad I have a deep well in a place that will never run dry.
