We are destined to see more of this in our lifetimes, given how some people treat the natural world and our animal kingdom neighbours..
Other sub-species of rhinos, and even elephants, may not be far behind.
But we are making progress. In the 1980s, it is estimated that over 600,000 elephants were killed by poachers in less than 10 years.
We are now "down" to 20,000 killed per year by poaching. But sadly, this is still more than are actually born in a year, so it's not quite enough progress, and there is still much work to be done.
If you feel like supporting conservation and education efforts to help with this progress, here are a few places to start:
The David Sheldrick Wildlife Trust[0], The Amboseli Trust[1], Save the Rhino[2], and of course the World Wildlife Fund[3] if you want to support conservation in a broader sense.

If anybody wants to read an extremely complete book on the subject, it's hard to do better than A Feathered River Across The Sky[0]. It's well written and the science is sound.

Many animals may have been spared extinction by humans due to the fact that the western world thought they were myths, until late in the second millennium AD when furthering exploration brought back evidence of their existence. Among them: tigers, komodo dragons, giant squid, giraffe, pandas, gorillas.
New Zealand also has some horrifying stories (the last group of a thought to be extinct bird was killed by a lighthouse owners cat after he’d sent one to be identified. I hate cats.)
I have to expect upwards of a billion people from this region will need to migrate to Europe and probably an even higher number to the Americas.
Africa (currently) has a lower population density than Europe or Asia. We know people can sustainably live at much higher densities than Africans currently do.
The drivers behind migration are global inequality and conflict. If you want to reduce migration, start there. Isolationism and closed borders will only ultimately lead to more humanitarian crises, and more migration pressure.
Even a place like Congo is, geographically, the size of Western Europe, with about 1/6th the population. Over population isn't really an issue in sub-saharan africa, conflict is.
The question seems to be wether those deals are crafted with both parties on eye level or wether they are imposed by one party.
Really? What are some places where people live sustainably at higher densities and at the same scale?
3 people sharing a sustainable farm doesn't count. You also have to account for the cities, which consume vastly more resources and produce vastly more waste.
In Greece 86% and in Italy 80% in polls want fewer immigrants allowed into their countries. More than 50% in the United Kingdom and in France plus 47% in Spain agree. How do you deal with this, ignore these voices?

I am a bachelor in Biology besides the computer degree and this is something I perceive as a deep loss not because of this specific specimen but because of the trend it again confirms. We have modified the key features a species need to survive because of the way we are and big beautiful beasts like this are essentially doomed unless we change our ways, which I am very pessimist about.
I guess this is something we will need to get used to, it is going to happen more times in the future, our grand children might be the first ones to not see a live elephant or giraffe animals so common in cartoons and they toys will be like dinosaurs for them. It's terrible to think about it.
Rhinos have been killed by humans by the hundreds of thousands over the last 30 years.
There's nothing natural about that.
Nope, that's not natural in my book.
It is worth noting that the word natural is itself not "natural", the word is a human invention used to separate our own activities from others.
Anything that's incidental to changes in the animal's environment, including increased predation or habitat destruction, would still count as natural selection. That includes cases where the predator is a particularly vicious species of great ape.
What does natural mean then? It's not like they disappeared by some magical event or an asteroid falling on the face of the Earth.
In the case of poaching, poachers are not intentionally trying to change the phenotype of the animal. They want to collect the horns/head/etc. The selection itself is an emergent side effect and, I would say, the natural result of a highly effective predator being introduced into the environment.
There is also the David Sheldrick Wildlife Trust[3][4] which takes care of elephant and rhino orphans (most of them are orphans due to poaching). For $50 a year, you can become a sponsor of a particular animal and they'll send you photos and updates about how your sponsored animal is doing. You can for example sponsor this little fella [5][6].

> Rhino horn can fetch tens of thousands of dollars per kilogram on the black market in Asia and, depending on the exact price, can be worth more than its weight in gold.
From what I've read, there has been some pretty decent progress in reducing demand for elephant ivory, which has a similar issue in Asia, due to various information campaigns. (https://www.economist.com/news/china/21678838-remarkable-pro...) Sadly, this seems to have not worked for the rhino.
Cell phone :-)
Two thoughts on this: 1) Isn't this billboard in the wrong continent and language? North Americans in central NC are not the ones killing and consuming these endangered animals.
2) (cynically) Billboards are expensive. There must be money to be made in this misery. I guess we are ripe for knee-jerk guilt-trips and the donations that follow.
It disgusts me.
(Unless they're revived by cloning, as one person mentioned, in which case either they remain in captivity or poaching continues.)
Vietnamese Javan Rhino. Extinct 2010
Northern White Rhino. Functionally extinct 2018
Sumatran Rhino. 100 animals remaining.
Javan Rhino. 63 animals remaining in a single population. None of them on zoos.

My point is that unless there is some way to restrict which 'biomes' different organisms can inhabit, some invasive species will outcompete others, particularly if some less competitive species are evolved for specific niche environments only found on Earth. This segregation is not likely to happen naturally as it has on earth, and thus the idealistic diversity and preservation that yohann305 was hoping for wouldn't occur without human intervention and control.
>if Kudzu somehow (perhaps a form of geological change happens in thousands of years like a land bridge, or continental shift, or maybe the seeds are simply moved by some migrating population of bird) reached these new ecosystems by it's own means, it would still be an invasive species.
If the plant migrated on it's own than that area is now its native area.
Also from [3]:
> Invading propagules begin as residents in a potential donor region (stage 0), some of which are taken into the transport vector (stage I), usually by humans. If these propagules survive transport and release to become introduced (stage II), they have the potential to establish (stage III) in a novel environment.
Note that 'stage I' notes 'usually by humans', not 'by humans'. Ie. a species which uses some natural phenomena as a transport vector can still be considered an invasive species. [1] says similar - "Human actions are the primary means of invasive species introductions." - implying that non-human methods are also possible for invasive species introductions.
It's nonsensical to say that as soon as something migrates using a natural phenomena that it becomes a 'native' to that area.
