Baiji River Dolphin May or May Not Be Extinct

ozmanjusri writes "Major news outlets are reporting that after 20 million years, Baiji (Yangtze River Dolphin) are now officially extinct. This is apparently actually old news; it was announced on a Baiji conservation website in December of last year. One outlet, though, is claiming they may not quite be completely dead yet. The same scientist that filed the report leading the the declaration of extinction is still hopeful: '"This is only one survey and...you can't have a sample in a survey, so you cannot say the baiji all is gone by the result of only one survey," he said. "For example, there is some side channels or some tributaries [where] we cannot go because of a restriction of navigation rules, and also we don't survey during the night-time so we may miss some animals in the Yangtze River." Professor Ding says based on anecdotal evidence, he remains confident the dolphins are still out there. "I'm pretty much sure there are a few of them left somewhere in the Yangtze River," he said. "I keep receiving reports from fishermen, they say they saw a couple of baiji somewhere, sometime."'"

I thought it was a cat?

Well, who's going to open the box and find out if the dolphins are dead or if they're cats?

So it's okay if I track you down and shoot you? After all, human beings die all the time. They did before I started locating strangers on the internet and shooting them, and they'll still die long after my bloody killing spree is ended by my death. It's not that big a deal, right?

  Note to parent poster: Death by natural causes is different from death by human intervention. The same goes for collective deaths, A.K.A. extinction.

May or May not?

I guess I'd better save the one I have in my freezer for a really special dinner, because I won't have to get another one. And the dolphin they're putting in those little cans is often adulterated with tuna, which spoils it in my opinion.

See, there's a big difference between mostly extinct, and all extinct. Now, mostly extinct: they're slightly not-extinct. All extinct, well, with all extinct, there's usually only one thing that you can do...

In all seriousness, with so few members of the species, they're effectively extinct, and that's what counts. There may be one or two, but there's zero chance they'll balloon into a viable population. Even if we save genetic samples, we're decades, if not centuries, away from being able to reproduce an entire species, if we can even do that. Even if we have tissue samples from twenty different dolphins, and reproduce them through some hypothetical cloning technique, I'm not convinced that's enough genetic diversity to sustain the species.

Hi. Chinese guy here. And yeah, you are being patronizing.

It's true that the baiji are somewhat significant in Chinese culture, but to the point you seem to think it is. Personally nobody I knew ever thought about them, or indeed were aware of them outside of field trips to some science museum. The whole "ancestors placed importance in baiji" and "Chinese venerate ancestors" is just one big non-sequitor I'm not even going to touch.

Keep in mind that the significance of the river dolphins was limited to an isolated geographical region, where the vast majority of Chinese did *not* reside. Maybe there are people living on the banks of the yangtze mourning their loss, but for the other 99.99% of Chinese people out there, things haven't changed a bit.

Now... Regarding your previous comment. While it's certainly unfortunate and sad that the baiji have been killed off due to human actions, in the end who is responsible? Want to dig Mao out of the ground and put him on trial for instituting the Great Leap Forward that encouraged such reckless killings? Good luck with that. In the end, commercial fisheries, massively increased boat traffic, and the construction of the Three Gorges Dam were primary contributors to the extinction of these dolphins. IMHO all of these have been critical to raising the standard of living and quality of life for the Chinese people. I wish we could have both (human prosperity and ecological conservation), and perhaps we could have under more effective leadership or more resources, but those were the cards we were dealt.

What would a serious conservation effort require to preserve these creatures? Stop using the Yangtze as an industry shipping lane? Spew even more toxic gases into the atmosphere by constructing the huge number of fuel-burning power plants that the Three Gorges Dam could replace? Stop fishing the Yangtze and deny a critical food source for the local population? I hate to be so human-ist about everything, but between the survival of humans the the survival of a bunch of dolphins, it's pretty clear which I pick.

So now the baiji are (probably) all dead. What did we receive out of that deal? Millions of Chinese are now far more prosperous than they were before. Remote regions are no longer starving, and many now have access to proper food, shelter, and medicine. The situation in China, especially the rural areas, is not pretty, but for the most part it's a lot better than it was before.

Only a matter of time

Not extinct yet? Check back in a few months, they'll be sure to be. But hundreds of species are on death row thanks to human greed and thoughtlessness, including the pangolin (UK Guardian):

5,000 of the world's rarest animals have been found drifting in a deserted boat near the coast of China.

The pangolins, Asian giant turtles and lizards were crushed inside crates on a rickety wooden vessel that had lost engine power off Qingzhou island in the southern province of Guangdong. Most were alive, though the cargo also contained 21 bear paws wrapped in newspaper.

According to conservation groups, the haul was discovered on one of the world's most lucrative and destructive smuggling routes: from the threatened jungles of south-east Asia to the restaurant tables of southern China. ...

Despite the ban on pangolins, many restaurants offer their meat. The Chaoxing restaurant in Shenzhen said yesterday that pangolin was available but was only suitable for large dining parties.

"The animal is very big - about 10kg," said a waitress contacted by telephone. "We serve it in hotpot. That is the tastiest way." ...

A Guangdong chef ... described how to cook a pangolin. "We keep them alive in cages until the customer makes an order. Then we hammer them unconscious, cut their throats and drain the blood. It is a slow death. We then boil them to remove the scales."

So while we thoughtlessly wipe out species after species, at least we treat every individual with unimaginable cruelty first. Yay humans.
