I’ve read in an Article that meat production causes a lot of co² emission. Now I was wondering if we stopped eating meat completely, would that be sufficient to get under the threshhold of emissions what the planet can process? What is that threshold? Where are we now? How much does meat add to this?
the danish study is actually worse in some ways. it additionally cites poore-nemecek 2018, who themselves referenced tilman-clark, but egregiously gathered even more lca meta-analyses, and created something of a meta-meta-analysis of lcas. it’s bad science all the way down.
Do you have any links for someone who wants to read more about these LCA and why they’re not combinable?
hilariously, you can read the references from poore-nemecek, where the meta-studies they cite, themselves explain the problems with combining lcas, but then say “we’re gonna do it anyway”.
understanding how lca studies are conducted should be sufficient to understand why meta-analyses are misuses of the data, and the wikipedia article about lcas does a pretty good job of explaining the issues with the methodologies
