Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

https://ourworldindata.org/emissions-by-sector gives a good breakdown of the worlds C02 production. Electricity and basic household use combined with transport are 73% of the problem. Livestock is 5.8%.

If every person on the planet installed Solar panels and completely removed their grid electricity and gas usage and replaced their car with an electric vehicle and didn’t use planes we could address 10.9% + 11.9% + 1.9% = 24.7% of all CO2 production. If we all gave up all meat then we could raise that to 30.5%. Its less than that however because only 60% of personal transit is actually passenger vehicles, not all aviation is people, some tiny amount of emissions for cement is going to be personal etc etc. That is the grand total that we have control over with personal replacement and some consumer choice and some of that livestock would go into other protein sources. The rest is all businesses and building and waste management that if we stopped using would no longer be developed nations and that we have no control over how its powered. Its fair to say business is responsible for reducing emissions of at least 70% of the problem.

I would also argue that there is no particular reason for consumers to be responsible for electricity CO2 production either when CO2 free alternatives exist, we might have the option to buy solar, wind and batteries but the grid is a better place to fix that in the same model so I think we could argue reasonable its even less we are directly responsible for. All of this is consumption for us and the economy, no people means no CO2 production but any CO2 we don’t directly emit (a car is direct as is a gas cooker or a wood burner) isn’t our fault its the business that burnt it to deliver that service/energy and we don’t get to control it so we can’t be held responsible for it.

The entire goal is to transition our lifestyles into something sustainable not to go back to there being 10,000 of us living like cavemen.

Animal agriculture isn't just direct livestock emissions.

It's land use, fertiliser, cropland, transport, electricity and water. All told about a fifth to a quarter of emissions.

The meat, dairy, egg, etc. industry represents around 14.5% of global emissions[1] - not 5% - when you include the emissions from things like growing feed and that's something we can only reduce a little bit with changes to industry practices. That is large enough that we can't really afford to ignore it.

To have any hope of meeting the central goal of the Paris Agreement, which is to limit global warming to 2°C or less, our carbon emissions must be reduced considerably, including those coming from agriculture. Clark et al. show that even if fossil fuel emissions were eliminated immediately, emissions from the global food system alone would make it impossible to limit warming to 1.5°C and difficult even to realize the 2°C target. Thus, major changes in how food is produced are needed if we want to meet the goals of the Paris Agreement.
