Earlier this week, I asked my twitter followers what they thought about shark fin bans, which prompted a long and stimulating discussion. What follows is my first attempt at “Storify”, shared in the hopes that the discussion can continue here.
As I’ve said before, I’m not a big supporter of shark fin bans because they don’t allow for sustainable, well-managed fisheries to supply the market. Additionally, they promote the common (and false) belief that shark fin soup is the only major problem facing sharks, and don’t address many of the other important issues associated with shark conservation.
Instead, I favor a comprehensive approach to shark management, including requiring that sharks be landed with fins attached (i.e. a ban on “finning” but the fins can still be used if the shark is landed whole), special protections for threatened and endangered species, science-based fisheries quotas for species that can sustain fishing, time/area closures or gear restrictions when necessary, and careful monitoring (including requiring that all fishing nations report the species composition of their catch).
Check out the great discussion if you missed it, and let me know what you think of this important issue in the comments of this post.

I am what most people would consider a “well-bearded” individual. According to this graph, I fall rather appropriately into the category of “Sea Captain”. Despite my proud embeardedness, I also play host to a horrifying parasite frequently referred to as a “neck beard”–a foul nest of bristles with a coarseness and consistency that lies somewhere between steel wool and dermal denticles. This means that, appearances aside, I still need to shave, sometimes twice, daily.
If you’re like most American men, this means using either disposable razors or cartridge razors, both of which result in discarded plastic and steel. Cartridge razors, commonly found with an increasingly horrifying numbers of blades, vibrators, laser pointers, and PEZ dispensers, produce less waste but are also more expensive. The average price for the three-bladed monster at my local pharmacy runs about $4.00 a cartridge, and those things don’t last very long–I’m lucky if I can get 2 weeks out of a single cartridge, often less (although, somehow, the very last cartridge in each pack seems to last 3 times longer than the others). In addition to wasting plastic and steel in the actual cartridges, and plastic and cardboard in the packaging, I’m burning around $100 per year.
There are a few possible ways to reduce shaving associated waste. The most obvious is switching to an electric razor–which is what our other beardly blogger did until recently (he now reports that “My beard used to destroy electrics in less than a year.“)–but the cutting heads need to be replaced and they will, eventually wear out. I’m also not a fan of electric razors, I don’t particularly like the shave I get with them. Next on the list are single-blade safety razors, the classic standard of the 1930’s through 80’s. These have the advantage of no plastic, and allegedly get you a closer, cleaner shave than disposables (though I suspect that has more to do with the brush/lather and spending more time on getting a good shave), but the blades are still disposable. So, it appears as though, if I truly want to eliminate as much waste as possible from my shaving routine, I need to take a more traditional approach.

eno. is the new literary magazine for the Nicholas School of the Environment at Duke University. Its mission is “to inspire a respect for our environment by engaging in thoughtful expression through the use of artistic, reflective, and creative forms.” This year, I have two poems and one short story featured. Both poems can be found … Read More “Recollections from a future ocean – a short story for eno magazine” »
Though oyster mariculture isn’t new to places like the Chesapeake Bay, Jay Styron’s Carolina Mariculture Company, based in Cedar Island, NC, is a shining vision of the future in North Carolina. Much of the state’s efforts in aquaculture are directed at tilapia, catfish, and hybrid striped bass, which are grown in ponds on traditional farm land. These are often grown as a means of diversifying an existing farm economy. Mariculture, though, blends this type of aquaculture with commercial fishing to grow seafood in estuaries and inshore regions, creating a saltier crop. In many ways mariculture should be embraced by both farming and fishing communities but is often instead viewed as the strange uncle of the food production family. Enter pioneer Jay Styron, who grows oysters not only for food but also demonstration purposes – and he proudly creates delicious oysters.

We tend towards waste. As a nation, as a community, and in our personal lives, waste is ubiquitous and often imperceptible. That we can afford to discard is an unfortunate side effect of having a high quality of life. Waste is not always a bad thing, either. We’re comforted by the fact that our doctors use disposable needles, that food can be packaged and preserved, that soiled diapers can be discarded. Disposability is freedom from the tedious chores of our grandparents and great-grandparents. It is access to time that can be spent with our loved ones or engaged in more fruitful pursuits. But there is still plenty of unnecessary waste that exists purely for convenience.
Those of us who consider ourselves environmentalist, good stewards of the earth, are often just as guilty of waste, myself included. Over the next several months, I will be exploring ways to reduce my own waste production. Each month I will identify some aspect of my personal life that generates unnecessary waste and explore solutions. Plastic is my major target, but I will also be looking for other resources drains that could be made more efficient (or, if possible, eliminated).

I’m a bit late to the party, but last week, several news outlets reported that the Diablo Canyon Nuclear Power Plant was taken offline by “jellyfish-like creatures” that clogged several cooling intakes. While most sources were careful to point out that these were “jellyfish-like” organisms, some secondary sources truncated the description and announced that “Nuclear Power Plant Knocked Offline By Tiny Jellyfish, The Invasion Has Begun”. Unfortunately, these organisms are salps, not jellyfish, and you’d be more correct to describe them as human-like rather than jellyfish-like.
Salps are free-swimming pelagic tunicates, one of the most basal members of the chordate phylum. While they superficially resemble jellies to the untrained eye, they are far more derived, possessing three tissue layers (compared to the jelly’s two), a primitive, larval notochord, a perforated pharynx, and the rudimentary beginnings of a centralized nervous system. They form large, clonal colonies that are able to take advantage of plankton blooms by rapidly producing more clones to capitalize on an unpredicatable food source. Although I don’t have first hand reports, this is likely what happened in Diablo Canyon, as warm water discharges from nuclear power plants can trigger massive plankton blooms. Far from a “jellyfish invasion”, this was probably the natural response of a predator to increased food availability.
