Two pieces of news about polar bears (Ursus maritimus). The first is some good news in an ongoing saga: Charles Monnett, the scientist who documented cases of drowned polar bears and was subsequently suspended by his agency, BOEMRE (the new acronym, since the Deepwater Horizon proved the final disgrace for a notoriously corrupt agency (discussed here)) has been reinstated from administrative leave. While investigations continue into why he was initially suspended and he will not be returning to the same duties, he has at least been temporarily cleared. This is something to keep watching as it develops though I wouldn't expect it to move with any great speed.
The other is much more unfortunate. A security guard working for BP shot and killed a polar bear with what appears to have been an explosive round when it wandered near a worker camp. While BP claims that the bear was killed by mistake and that the guard believed he was firing a rubber bullet to ward off the bear, it is a positive sign that the Fish and Wildlife Service is taking it seriously enough to do a preliminary investigation. There is nothing in the piece to indicate that anything other than what BP claims is the case, but polar bears are a threatened species and it is important to determine the exact circumstances of the death, whether it was preventable (assuming it was unintentional), and whether it was justified.
Threatened and endangered species receive a large amount of protection from the Endangered Species Act. There is a broadly construed ban on any kind of harm to individuals without a permit, and even then allowances are made only for specific numbers taken in specific ways (for example, a dam might be allowed to "take" 2,000 salmon via turbine action per year or a construction project might be permitted to take a nesting pair of owls via habitat disruption). While there is an exemption for lethal force when necessary to defend human life, that does not appear to be the case here, and scaring it off would have been the appropriate and justified choice for the safety of workers and the bear. The polar bear was listed as threatened due to loss of habitat from climate change and much has been written about that threat to the bear including how best to respond to protect it. However, once listed as threatened, unless specific exemptions have been written into the listing rule, the species is broadly protected from any type of prohibited action. In other words: once listed, it doesn't matter why. Any harm is prohibited harm, even if it isn't the kind that caused the listing. This is another piece that bears (unfortunate pun that wouldn't happen in many other languages) watching though I expect it to disappear into the ether without much closure.

Sharks and Rhinos
Last week I saw two articles that I thought would be interesting to juxtapose. The first is a piece from the NYTimes on the increase in the theft of rhino horns as trade in legal horns has become more difficult (the increased CITES and EU restrictions have also apparently increased poaching, but are on the whole a positive. Rather than loosen restrictions it would be best to increase commitments and support for conservation and anti-poaching forces and economic development to alleviate the poverty that makes poaching and trafficking a desirable way to earn a living). The second was a short piece in the LATimes about the advancement of a ban on the sale of shark fins through a legislative committee in the state senate.
First off, some housekeeping: I am not a vegetarian, though I do try to eat responsibly. I also am not opposed to hunting or fishing generally (and have partaken in those activities), but especially not as game management techniques where other top predators have been removed or when dealing with invasive species. I also do not want to get into a big philosophical or ethical discussion about the propriety of having all these specimens of endangered animals floating around the developed world. Yes, specimens are necessary for scientific study and the expansion of knowledge (and increased awareness of biodiversity). Yes, more specimens were taken in the days of colonialism than were necessary, and for less than noble motives. But they were and we have to move forward from that point. You can't return a stuffed rhino to the wild, any parallel to the Elgin Marbles is superficial and ultimately false.
Now, onto the actual comparison. Both rhino horn and shark fin soup are traditional Chinese medicines and foods. That's pretty well established. However, there is much more general condemnation of the former than the latter. While use of rhino horn is portrayed as ridiculous, observe the outlandish list of purported powers it has, "aphrodisiac," cure for cancer coupled with the commentary from a scientist that ingestion would be "about as healthful 'as chewing on your fingernails.'" There is no room for cultural differences. It is represented as dangerous, destructive, and misguided, based on superstition not on science.
Contrast that with the proposed ban on shark fins. While there is already a ban in other western states, the battle in California is getting heated as it constitutes a much larger economy than its Pacific neighbors. In the short piece on finning, the dispute is framed as conservationists versus those seeking to preserve their cultural heritage (whether perceived or constructed, shark fin was long a food for the elites in certain regions and has only become more widely consumed as technology and economic development have reduced costs and increased incomes). While the tone of the article does convey a bit of he said/she said, it does ultimately appear to come down on the side of science and conservation, strengthened by the quote from a state assemblyman who is originally from China, grew up with shark fin soup, and has since come to reject it (as have a number of other prominent Chinese people including Yao Ming). The accompanying photograph illustrating a shark finning vessel, lines strung up with fins (sharks presumably lying dead and bleeding on the ocean floor) also serves to make the point: finning is brutal, cruel, and damaging to the health of ocean ecosystems (as well as to the sharks). It's also incredibly unhealthy for human consumption. As top predators, sharks accumulate toxins such as mercury at very high levels via biomagnification. In many species these toxins can reach hazardous levels.
I know that's a lot of material to pull out of a blog item, but I thought it made for an interesting comparison, and one that gets back to one of the things I want this blog to explore: what is the real value of nature and the biodiversity of life? Does it have its own inherent value? Is it simply a social construct? Does one culture or society's value or construction take precedence over another's? Should it? What are the processes and circumstances that lead to a change in these constructions and how can they be enabled or impeded?
None of these have clear answers, and answering one might destabilizing your answer to another, but they are definitely worth thinking about. I try to keep them in mind as I go through life (even when I'm not writing here, which I should do more often) and I hope you do too.
