I am sorry but I really don’t like and don’t find useful at all these kind of posts. Besides, I thought the aim of this forum is giving information, not advocating. Although this post provides some very good calculations and information, it misses the key point—it is 100% value-dependent—and the post is plain advocacy. I’m not against the bottom line, I’m really not decided in this topic (though I tend to lean to the contrary position), but it is really uncomfortable (? probably not the word I’m searching for) to see this here.
“Replacing chicken meat with beef or pork is better than the reverse”. Well, as said above, this is so if one holds your values or similar ones all else equal. You don’t say how much pain would you agree to exchange for how much CO2. I find it totally understandable, I don’t think anyone can give a good answer for their thresholds—I certainly don’t have one for mine—but this makes the whole post bullshit. “I think this, here are some not complete calculations that I say support thinking this, but if the calculations were different I state no reason to make anyone think I would stop thinking this. Don’t you think that these calculations support this?”
You are not sure whether wild animal’s lives are worth living, so you don’t account for land. Well, it is alright, but it is again a values thing. In addition, we actually do know that the diversity and size of natural ecosystems are important not only for the “natural” world, also for us humans, so it should be accounted for. Health effects are mentioned, great. But not quantified and compared as well.
Making numbers can be useful to get the sense of problems, but reaching a conclusion through numbers is only possible if one is able to make all the numbers needed with enough accuracy. It is no problem to give rough estimates, of course, but they carry large errors and errors compound, so pretty soon conclusions cannot be based solely on making numbers over rough estimates. In addition, rough estimates are usually values-based, so why not just state the values? One can very well argue “this rough estimate seems to me larger than this other rough estimate and so on, and based on my values, then, this conclusion follows”. Calculations can aid such comparisons. But your argumentation is not like this at all.
Compare the paragraph “Do you feel like the above negative effects (...) justify (...)? I do not” to “Based on my values the results of these quick calculations do not seem to justify (...)”. It reads very different. And subsequently you give additional information relevant for whether or not the thing is justified! How can anyone decide if something is justified before having all the relevant information?
This post seems like just a rationalisation of your values. So, better plainly state what you feel, give arguments and uncertainties, maybe support some of those arguments with some calculations, but do not focus on calculations and, particularly, do not pretend that the solution follows from those calculations. And, please, acknowledge that this is a values thing. You have yours, I have mine, and everybody has theirs.
I don’t have any intention to be harsh with you or this post—sorry if I’ve been too direct, I already spent way too much time writing to polish the text. I just tried to be comprehensive because these issues are quite common in this forum, and I really think they are harmful. Seeing the reality is the first step needed to be able to change it and numbers can put a scientific and objective gloss on things that are completely or mostly values-led. Let’s avoid it or/and be clear with what we do!
[Edit: And please, for those of you who don’t agree with the comment, spell out your disagreement instead of downvoting to hide it. A couple of sentences suffice.]
