Maybe, this sounds a bit silly but honestly, today, I would really like to know who are really these (in)human beings who supposedly eat all these animals or parts of them and make some species die out.
For decades - since about 1975 - I hear now even in Germany that someone in Asia is eating e.g. "shark fin soups", "rhinoceros horns" etc. as aphrodisiacs, bat wings and now pangolins imported from Africa to China.
Who are these crazy humans with superstitious beliefs and why does it seem possible for them to pay so much money for decades?
They cannot have been simple Chinese people when you remember the poverty of communist China only 30 years ago.
The UN should really have tried to find out at least 40 years ago who has so much money to pay poachers and traders in Africa already 50 years ago.
I think this could be a tricky subject to discuss because there are multiple aspects to consider.
First off, if the question is about inconsiderate consumption of animal products from rare species to drive them go extinct, I think there's no excuse to avoid our condemnation.
However, it's not really a problem specific to China or any Asian countries, because there have been countless animals and even human species that faced extinction because of the Europeans in the past.
But I agree that some of those countries which either have only recently attained the developed status, or still in the developing stage may show less awareness of such a problem. However, if we consider the fact that the very reason why they happen to lag behind the civilization is almost invariably related to the exploitation and political turmoils they had suffered because of the Europeans, I don't think it'd be fair to blame it squarely on their being Asians.
But if the question is about eating 'gross' or 'odd' things like bat wings, or rhinoceros horns, I'd argue that it's just the difference in culture. I believe many countries, European or Asian, have some of such cusinary oddities, from raw livers to snails. And if China is specifically notorious for such things, we should remind that it's also a country with one of the most ancient and diverse culinary traditions in the world. It certainly survived despite all the hardships the country have undergone since the collapse of their ancient empire.
Of course, I won't deny that there's a peculiar aspect in certain East Asian culture that you mentioned as 'superstitous' and I do agree with you largely on that matter. As a person who was born and raised in one of such culture, I've seen many who still believe drinking deer's blood or eating a seal's penis would make you either younger or more energetic in bed. Diversity in culinary tradition is one thing, but holding such unscientific beliefs is a different matter.
But again, I mainly see such a problem as the result from their society having been lagging behind the civilization. For instance, such practices in my country have been rapidly disappearing, and almost entirely eliminated now, although I remember it was much more common when I was young. So, it's not really about being a Chinese or an Asian that is the problem, but that the culture in which they were born and raised need a bit more time to catch up with where the rest of the world is now.
All in all, I think the more important problem is not in what we eat (as long as it's not an engendered species), but how we eat them.
I don't think there's any problem in eating either shark's fins or goose liver, per se. Rather, I think it's such shamelessly inhumane methods that they use to harvest those animal parts that is the real problem. And again, the matter of animal cruelty is essentially the 'first world problem', and it hasn't been long since the Europeans began to put serious efforts to acknowledge and mitigate the problem, and even nowadays, they aren't entirely free of such practices as you can see in the case of Foie Gras.
So, while we should do our best to encourage those from the developing world or from those countries only recently joined the developed group to acknowledge such problems like protection of engendered species or animal cruelty, I think we should be more cautious not to regard such things as a 'Chinese problem' or 'Asian problem' as if it has something to do with their peculiar ethnicity, rather than their unfortunate historical hardships which have deterred them from making social progress as fast as the Europeans have in recent centuries.
Of course, I'm not calling you a 'racist' or anything for what you wrote. But since you have exclusively mentioned of Asian or Chinese people as responsible for such practices, I wanted to provide the reason why we shouldn't see such a problem as pertaining to any specific ethnicity or nationality.
