!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
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.
Questions 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 META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser 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.
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- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

Bye-bye is probably a bit of an overstatement. Yes plants need phosphorous, and some more than others, but I don't think the Amazon would disappear without the phosphorous influx from the Sahara. Change - sure, probably - but there's still plenty of nutrients and water for vast forests to continue existing there.
The soil itself is pretty barren in the Amazon. The vast majority of the nutrients and minerals in that biome are in the trees and plants themselves. Without the continual topping-up from the Sahara, the Amazon is on a ticking clock.
Gaze upon the Amazon River:
Consider its breadth and depth. A titanic quantity of water, enough to drain a continent, emptying in endless torrent into the abyss of the sea. Except it's not just water. Look at the color of it. It's not blue; it's brown. Consider the amount of water in that river. Then think of how much soil and dead plant matter must be flowing with it in order to turn it to such a rich chocolate brown.
That is where the Amazon's phosphorous ultimately ends up. Nothing lives forever. Every plant and animal eventually dies. When it does, much of what it was gets recycled back into the plants and animals of the Amazon, but some doesn't. A lot doesn't.
Without the Sahara, the Amazon is on borrowed time.
Let's say that if the nutrients of the Sahara were consumed by plants and animals in the Sahara, then the Amazon would be deprived. Let's say the Amazon would disappear.
In turn, we'd get a forest in the Sahara that would be about 30% bigger than the Amazon. So a net win I guess?
Anyway, it's not the point. I'm just saying it's moronic to belive that we can terraform fucking Mars.
I would say that you should have more faith in your fellow human beings. We would have never accomplished anything if our ancestors had your poor misanthropic attitude.
Haha okay, I'm the misanthropic one for pointing out the normal course for allocating resources for scientofic efforts? I want science to continue to be directed toward tangible goals, with an emphasis on things that help people. That's how it's normally done. It has worked very well in the past and I see no evidence that we need some tween boy fantasy to improve upon a proven concept.
We could use Brawndo, it has electrolytes.
It's what plants crave.
