I have many problems with your post that I think wouldn't be present if you had intellectual integrity and had sourced your claims properly. Or at least, it would be clear where you were getting your faulty assumptions.
First of all you say, 1) overpopulation is a problem (in general) and 2) but it's not caused by us. Either, you are absurdly overconfident, confident enough to make a statement about the massively complicated situation of population growth and maintenance and where the blame for this assumed problem lies, without consulting an expert, or you're getting it from somewhere, and you're not citing that somewhere. That's the first error I notice, and it's one of essentially not knowing or not presenting the background for this problem, but still wanting to make absolute claims of where the moral responsibility should lie.
The strongest versions of arguments about where the problem originates are clearly more complex than this. You can't just say, it's africa and china, and that's it, no one else is at fault. It's got the mark of some kind of demagogue. You make no mention of colonialism, global power relations or disparities in wealth and education, as if these have nothing at all to say about the aetiology of the situation, when clearly these are at the very root. Shoddy and immoral intellectual work, simply, offloading your share of the blame to the only elements which benefit you. Shoddy indeed. I'll come back to this.
This is further reinforced in my mind, that you don't know what you're talking about, when you make factual errors in your representation.>China has a policy that each couple of only allowed to have one or two children
All couples in china are currently allowed two children, it's been this way since 2015. So it's not that they're either allowed one or two children, it was one, and now it's two.>yet many more are born and simply abandoned
This is not false, as far as I'm aware.>While some of these girls may end up being adopted in other countries, many of them end up being raised in orphanages and staying in China to have children of their own, rendering this law rather ineffective in their population growth.
This claim requires so much citation. Especially considering that China's rate of population growth has been dropping rapidly since the 1970s to a point where it's now below that of other developed nations. It's true that some children are raised in orphanages, but you're misrepresenting the situation. And furthermore, these days, the proportion of boys and girls is split up pretty evenly, so another example of incorrect or outdated information there:http://holtinternational.org/blog/wp-content/uploads/2012/06/Changing-Face-of-China-Adoption1.pdfhttps://www.lwbcommunity.org/the-changing-face-of-chinas-orphans>As for Africa, their population has exploded due to our foreign aid
This statement and the statements that follow are not an accurate representation of the aetiology of the problems in africa. These kinds of 1970s lifeboat ethics are unfair, self-serving and myopic, when applied to africa with the intention of cutting of all kinds of foreign aid.
As many scholars have competently put forward, these kinds of lifeboat ethics are not useful or constructive ways of viewing the problem on their own. You've got a half-truth, a tiny fraction of reality, and you're being led to a biased conclusion on that basis. You've essentially got on your intellectual blinders, only paying attention to the perspectives that are in line with your own world-view, and ignoring any causal factors or perspecttives, which might contradict with your ideology.
Is overpopulation a problem? Yes. Do I have any sort of responsibility for it? No, because see, here are two ways of framing the issue which only emphasize africa, and let's just ignore all that history and all of those geopolitical factors, which actually could support my country being the direct cause.
For a country to completely abandon responsibility on this ethical basis, this is the equivalent of kicking someone in the face, and then taking a step back and raising your hands and saying, 'well look, he's the one bleeding all over the parking lot, how can you say this is my fault'.
There's plentiful corroboration for this particular kind of worldview being too one-dimensional. Here's two papers that touch on this, which I enjoyed. Arguably not the best, but it's the ones I've read, so it's the ones I feel I can present knowing what's in them.https://www.ghi-dc.org/fileadmin/user_upload/GHI_Washington/Publications/Bulletin42/065_nocartoon.pdfhttps://doi.org/10.1080/02698595.2017.1316114>telling men and women to reproduce less doesn't work, because as bizarre as it sounds, many men and women in Africa simply don't know that sex results in children.
This is actually -- incredibly -- factually incorrect as far as I can tell, and also self-defeating, even if you take the factual error for granted. You're here arguing that because a significant portion African people are ignorant that sex leads to new life (citation really needed btw, this is not the case from what I've read), it is therefore futile to try and educate anyone. But that's exactly what education is for, man. That's what it do. Your idea defeats itself.>This means Africa's population is just going to keep growing unchecked, and is going to require more and more aid.
Incredibly fatalistic take. And again, based on this notion that african people are incapable of learning. Not really something I'd consider consistent with reality. Almost as if you viewed them as being a lesser race or something. But I'm sure you don't. That's not something you would do, is it?>Our own countries don't or hardly contribute to the overpopulation problem. In fact, one of the reasons that most pro-immigration politicians cite is the fact that the local population isn't reproducing enough. So they then import hundred of thouzands of migrants, and then try to tell us that our country is overpopulated.... Isn't that crooked?
Completely unsurprisingly, though, it is possible for a country to both be overpopulated, in the sense of the word that it requires an import of food and goods to maintain population, but still have demographic problems that make a temporary influx of people to manage the work force a good thing for the economy. These are not at all mutually exclusive situations. I feel like you literally don't understand how demographic problems work.
