The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with YSK.
All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.
Rule 2- Your post body text must include the reason "Why" YSK:
**In your post's text body, you must include the reason "Why" YSK: Itβs helpful for readability, and informs readers about the importance of the content.
**
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-YSK posts.
Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you harass or discriminate against any individual member, you will be removed.
If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- The majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.
Rule 11- Posts must actually be true: Disiniformation, trolling, and being misleading will not be tolerated. Repeated or egregious attempts will earn you a ban. This also applies to filing reports: If you continually file false reports YOU WILL BE BANNED! We can see who reports what, and shenanigans will not be tolerated.
If you file a report, include what specific rule is being violated and how.

Not really, check out their claim on google. Ships are polluting a shitton. They have huge engines that run on the crappiest fuel known to man. It's so bad, that they have to switch to diesel by law when comming close to the shore / port so as to meet any semblence of environmental law. Something like the top 10 ships pollute more than all cars on Earth combined (exhaust gasses, not tire wear / brake dust).
I did check it ... doesn't seem to check out, not even close.
Here is a pretty neat interactive graphic: https://www.wri.org/insights/4-charts-explain-greenhouse-gas-emissions-countries-and-sectors
If you click on the energy -> transportation sector, you'll see it's about 80% from road traffic.
Over all ships only make up a tiny amount (0.3% of global emissions).
Is burning bunker fuel in international waters very polluting and should someone try to do something about it? Yes it is and yes they should. And the good news is that they have been working at it: https://www.imo.org/en/mediacentre/hottopics/pages/sulphur-2020.aspx
But were the more polluting cargo ships from the past more polluting than "a continent"? Probably only if that continent was not Asia, Europe, America or Africa. If they were and I'm wrong, then I would love to see a source. Telling me to "google it" is not a source, I already tried looking for it when I first asked the question and I could find no info about this claim. It seemed like a hyperbole comparison that they made up.
I also tried looking up your claim that 10 ships pollute more than all cars combined, and the first result was an article debunking a similar myth (about 15 ships): https://www.oldsaltblog.com/2021/04/no-sixteen-large-ships-do-no-pollute-more-than-all-the-cars-in-the-world/
