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.

With the current food growing technologies, we can handle 10 billion comfortable well. We will obviously not reach that number anytime soon. But we are on track to shrinking rapidly in many nations. That will destroy these nations.
I think that there are a lot of 8 billion people who would disagree with comfortably well. That number needs to be closer to two, to be sustainable with earth's resources. At least that's my understanding, not disappointed if wrong.
The problem is not the resources, it's the distribution. No political will to end global poverty, no profit in feeding the hungry.
Oh absolutely, people gonna keep being people. The truth seems to be that we don't really know, but it's likely somewhere between 4 and 16 from the little bit of reading up I just did.
Yeah, I tend to most notice reports of overfishing. Food from land sources is almost entirely farmed but we still get a lot of seafood from wild sources plus don’t have aquaculture anywhere near as advanced as agriculture: there’s not much we can do. Loss of a marine food source is a big deal, and we keep doing that with more species. One solution is fewer people
A lot of the higher estimates assume we can overcome limitations like this with better management of resources, but that is against human nature and our current incentives. It’s not going to happen, even if lives depend on it
Let's not forget water.. And eventually, oxygen.. But keep buying/selling those trinkets people, for the economy.
And well, how much of these resource estimates leave enough for other life too, or does all other life just exist to feed us?..
I doubt that. Current conventional food production is highly fossil fuel dependant (everything from fertilizer to processing to transport). Earth's ariable land and top soil is decreasing quickly. Ecosystems are collapsing from the effects of agriculture and climate change. Most "advances" require more inputs and energy, which means more fossil fuel use, further accelerating resource degredation and climate change. I forget the statistic, but humans already control a significant proportion of Earth's biomass. This chart from https://www.greenpeace.org/international/story/17788/how-much-of-earths-biomass-is-affected-by-humans/ might be what I was thinking of:
About 30-40% of food is wasted in the US, in India its 22%, in China 27%. These are the largest nations in the world. The reality is that we can build more efficient infrastructures that can drastically cut down on this. But we don't need to yet, because it's not cost efficient. That's how much 'free' resources we have produced based on current technologies.
