Thriving Oceans

This is the latest U.S. Ocean Policy Report Card (produced by the Joint Ocean Commission Initiative) that I can find.  So I’m left wondering how much we have actually improved over the last 2 years and how we’d we rate ourselves in 2008 and 2009 in terms of progress?   I’m indeed looking for real change, not lip service, and at least a B average for crying out loud.  Well, the recent release of the Interim Report of The Interagency Ocean Policy Task Force is spelling out known problems so perhaps more ocean friendly policies can move forward sooner rather than later…

“… biological diversity is in decline due to overfishing, introduction of invasive species, and loss and degradation of essential habitats from coastal development and associated human activities. The introduction of non-native species can carry significant ecological and economic costs. Human and marine ecosystem health are threatened by a range of challenges, including increased levels of exposure to toxins from harmful algal blooms and other sources, and greater contact with infectious agents. Areas in numerous bays, estuaries, gulfs, and the Great Lakes are now consistently low in or lacking oxygen, creating dead zones along our bays and coasts. Unsustainable fishing (e.g., overfishing) remains a serious concern with consequences for marine ecosystems and human communities. In the Arctic, environmental changes are revealing the vulnerability of its ecosystems….”

“I found a cure for the plague of the 20th century, and now I’ve lost it!”  Perhaps it was the connotation of the quote itself or a combination of the fervor in Dr. Robert Campbell’s voice that made it stick in my mind after all these years, but in any case that early 90s Sean Connery flick is ever so applicable.  If you haven’t seen Medicine Man, it follows the quest of a researcher on the verge of a discovery of a cure for cancer in the Amazonian rainforest.  The scientist’s desperate attempt to replicate a serum produced from compounds he originally derived from a flower continues to result in failure.  The climax (spoiler) reveals the cure’s source was not the flower but a species of a rare indigenous ant, whose only known location is lost to the bulldozers and fires of deforestation.

Perhaps not as sexy as the fauna of the Amazon nor as adventurous as Dr. Campbell’s pursuit, scientists studying sea cucumbers in the Egyptian Red Sea are making the same leap for a need of conservation.  In an all too common scenario not limited to rainforests, the marine environment is being overharvested for direct and immediate consumptive values while potentially losing important options values that could be discovered through bioprospecting.

As a result of overfishing of sea cucumbers in the Red Sea, a ban was initiated in 2001 and 2003.  However, the ban did not lift demand and as a result illegal harvesting exploded.  With lackluster recovery of commercially prized species, researchers found a need to tie potential future drug treatments and long-term economic development to survival of the sea cucumbers. 

“Given the importance of economic development in countries such as Egypt and the perceived low conservation value of invertebrates such as sea cucumbers, the linking of these factors to conservation is vital for the maintenance and sustainable exploitation of these animals.”

Researchers collected a total of 22 species and screened 11 of various commercial and non-commercial value for bioactive substances.  Although their results showed no activity against either gram-positive or gram-negative target bacteria, all extracts were active against eukaryotic cell types, were most active against a mammalian carcinoma cell line, had a level of variation suggesting that the extracts contained more than one active compound, and that these compounds act at more than one site.

“The conservation value of a species is often defined not only by its rarity and distinctiveness, but also by its utility. This utility is reflected in its economic value, which can be further refined into its direct,  indirect, and options values. Overexploitation of marine resources for their immediate, direct benefits may be at the expense of future options value of a particular resource.”

Just as a fictionalized cure for cancer was simultaneously found and lost in the Amazonian rainforest for some immediate short-term gains, so too could we easily witness the vanishing of a species like the sea cucumber along with the next great drug discovery.  When you connect the ecological and potential options value, in terms of unique bioactive substances, of a marine species there is no doubt that it overshadows any perceived direct value we assign to them.

And this message of conservation is one that is germane to all nations.

Learning from our mistakes is one thing, but mixing half a ton of dynamite with a dead beached whale is another.  Setting aside any comments for now regarding last week’s discovery that a NOAA contracted vessel struck and killed an endangered blue whale, an apparent question weighing on state officials minds was what to do with the enormous carcass.  Although they opted to let nature run its course, the folks in Oregon County were a little bit more ambitious, or perhaps watched a little too much Myth Busters for their own good. Try explaining this one to your auto insurance company.

Let’s send out some positive ocean vibes and get a jump on the weekend with a photo session of one of my favorite sea creatures…Seahorses!

Seahorses belong to the genus Hippocampus which includes more than 47 species.  Showcasing a multitude of colors and sizes, they  are adept at camouflaging themselves amongst seagrasses, coral reefs and mangroves in the shallow tropical and temperate waters throughout the world.  And for those keeping track the Leafy Sea Dragon rounding up the session belongs to the genus Phycodurus, but but nonetheless is still a seahorse relative…

On October 3rd I had the great opportunity of attending the Wildlife Conservation Expo in San Francisco.  The speakers were not touching on ocean topics (if interested check out my posts on JournOwl.com), but there was an array of conservation groups in attendance that managed to cover marine wildlife.  And a couple of those groups persuaded me to pose for photo ops in support for whales and 350 species threatened by climate change (i.e. polar bears, orcas, penguins, walrus).

The International Fund for Animal Welfare’s program Tails for Whales has me doing exactly what the program set out to do…making a whale tail with my hands.  And what does the photo accomplish?  “By adding your photo you’re becoming part of a worldwide people power movement petitioning governments everywhere to stop whaling.”  So perhaps you may just find my picture in the future U.S. version of the Tails for Whales book and using my voice (or photo) to help end whaling.

The second opportunity for a photo petition came from an organization of which I am a member, The Center for Biological Diversity (CBD).  OK, this might be an ocean site, but I chose to pose with the frog at the delight of the CBD representative.  I was the first to choose the frog at the event, perhaps starting a small trend for the day.

The program is designed:

“To dramatically illustrate why we must reduce carbon dioxide in our atmosphere to no more than 350 parts per million to save the planet from climate catastrophe, we are creating 350 Reasons We Need to Get to 350 - a Web-based photo installation with descriptions of 350 species we may lose to global warming if we don’t act soon and strongly.”

“Your photo will become part of a collection of Center photos that 350.org will deliver to media and world leaders at the United Nations climate conference in Copenhagen this December.”

All in all it just took a few photos to lend support to a couple of worthy conservation organizations so set modesty aside and save those whales!

Sometimes it takes a meal  to get some notice.  And the next time you try to order fish and chips and the basket comes back heavy on potatoes don’t blame the waiter or waitress.  Our ocean gluttony has decimated the popular batter-dipped fish over the last 40 years.  Gluttony is the key word as our fishing practices are less than sustainable to say the least and the result of consuming a species faster than they can reproduce should not surprise any of us. 

The fact is that cod are vanishing, which is why the European Union is calling for sharp cuts to fishing quotas.  But are “sharp” cuts up to 25% in some fishing areas enough to ensure the species fully recovers? I’m not convinced!

Here are a few points to consider:

• In the 1970s more than 250,000 tons of cod were estimated to fill fishing zones in the North Sea, eastern British Channel and Scandinavia’s Skagerrak Strait
• Stocks are now hovering around 50,000 tons, a mere 20% of historical estimates
• “…will seek to cut the catch in some fishing grounds around Britain, France, Spain and much of Scandinavia from 5,700 tons this to 4,250 tons in 2010″
• “The scientific prognosis for most stocks is not encouraging, with many in a worse state than last year,” Britain’s Department for Environment, Food and Rural Affairs
• “Overfishing off Canada’s maritime provinces exhausted the world’s richest cod grounds and forced the government to impose a fishing moratorium. The collapse wiped out more than 42,000 jobs, and 18 years later the fish have still not returned. Some Canadian scientists believe the collapse of cod stocks off Newfoundland and Nova Scotia changed the marine ecosystem so dramatically that it may be impossible for cod to recover.”
• In the U.S., the two major New England cod fishing waters have witnessed steep declines with catches totaling only 3,868 metric tons in 2007. This is about 19% of historical catches in the 1980s (20,000 tons annually)
