"Safeguarding the Health of Oceans," a new Worldwatch
Paper by Senior Researcher Anne Platt McGinn, 1999. Turning the Tide to Save
Oceans, Citizens and Governments Build New Alliances
From coastal zones to the high seas, a growing wave of
citizen groups, businesses, and governments is mobilizing to save the oceans
before human activities destroy them, reports Senior Researcher Anne Platt
McGinn in a new study, Safeguarding the Health of Oceans.
McGinn cites a host of efforts already underway to protect
the seas:
* Unilever, which controls 20 percent of the whitefish
market in Europe and the U.S., has agreed to buy only fish caught and produced
in an environmentally sustainable manner.
* Volunteers in the Philippines, Thailand, India, and
Ecuador are replanting mangrove areas to repair earlier damage from shrimp
farming.
* In northern Sulawesi, citizens have cleared coral reefs of
harmful invasive species.
* The United States and Canada have each banned oil drilling
on large portions of their continental shelves.
"We need to devote far greater resources to protecting
oceans," McGinn said. A tax of just one-tenth of one percent on industrial and
recreational ocean activities would generate $500 million a year, more than 5
times the annual budgets of two important ocean agencies, the International
Maritime Organization (IMO) and the Fisheries Department of the U.N. Food and
Agriculture Organization (FAO). "Saving the oceans will take these efforts and
more," said McGinn, "because we've already pushed the world's oceans close
to-and in some cases past-their natural limits."
Seven out of 10 commercial fish species are fully or
overexploited. Moreover, many of their spawning grounds have been cleared to
make room for shrimp ponds, golf courses, and beach resorts. As a result of
habitat degradation, insured coastal property damages in the U.S. soared to $50
billion in the 1990s. The number of poisonous algal species identified by
scientists has nearly tripled since 1984, increasing fish kills, beach
closures, and economic losses.
"Bad news for oceans is bad news for the economy and
ultimately for humanity too," said McGinn. People obtain an average of 16
percent of their animal protein from fish. About 2 billion people-one third of
humanity-live within 100 kilometers of a coastline. Clean beaches and
coastlines attract millions of visitors each year and provide billions of
dollars in tourism revenue. Toothpaste, salad dressing, ice cream, and first
aid products all depend on the gel-forming properties of brown algae.
McGinn cites a number of problems facing those concerned
about the fate of oceans: the marine conservation community is fragmented; bans
on destructive activities are routinely ignored; too many regulatory
organizations have a development-first mindset; and enforcement and oversight
are not altogether lacking. The U.N. General Assembly spends just one day a
year covering issues that affect more than half of the planet.
"We have to increase public awareness and participation if
we are going to mobilize the broad constituencies that can protect oceans
locally, nationally, and internationally," McGinn said. Recreational activities
are a prime source of contact with oceans. In 1997, more than 35 million people
visited an aquarium in the United States. Worldwide, more than 5 million people
went on a whale watch, 7 million went scuba diving, and some 300 million spent
their vacation at a beach.
Because the most productive areas of the ocean are under
national jurisdiction and 80 percent of oceanic pollution originates on land,
addressing global marine issues requires strong national and local policies. A
number of countries have adopted coastal and marine zoning laws and management
plans, bans on oil drilling and other destructive practices, trade measures,
taxes and fees. To pay for some of the costs of management, New Zealand and
Iceland charge fishers user fees and Mozambique and Bonaire charge tourists
diving fees. The U.K., Norway, and Denmark all tax offshore oil and gas
production in their waters.
Several international institutions that were set up to
develop marine resources 50 years ago, including FAO, IMO, and the
International Whaling Commission, are today adopting policies that emphasize
more stewardship and conservation. The IMO, for example, has overseen the
tightening of regulations on oil transportation. Since 1981, the occurrence of
oil spills has been reduced by 60 percent, even though the volume of oil
transported has doubled. The IMO is now trying to extend this success story to
deal with threats from ship paints and ballast water discharge.
But a great deal of work remains to be done at the
international level. Five years after the Law of the Sea entered into force,
the number of countries that have ratified it has doubled to 130. Known as the
"Constitution of the Oceans", the Law of the Sea provides a comprehensive
framework for ocean protection. The United States is one of only eight
countries worldwide that still has not ratified it. Also, the international
convention addressing fish that swim across political boundaries is not yet in
force as it lacks support from key fishing nations. After nearly a decade of
political wrangling, voluntary guidelines to address land-based pollution still
have not won the support of national leaders. And while a global ban on a dozen
long-lived synthetic chemicals that threaten ocean life is close to becoming
reality, industry introduces hundreds of new ones that quickly become part of
marine food chains each year.
The ongoing explosion of new technologies for exploring and
monitoring oceans presents new opportunities and new challenges. On the one
hand, these technologies are rapidly expanding our understanding of the
complexity and fragility of oceans, especially in the previously unknown
reaches of the deep. Scientists have found entirely new forms of life clustered
around thermal vents discharging warm plumes of mineral-rich water. One such
organism, Pyrococcus, is the key to polymer chain reactions (PCR), a process
that has advanced genetic research.
In the Atlantic, tuna are tagged with pop-up transmitters to
track their movement and record their origin, producing data that will help end
disputes over the conservation of western and eastern Atlantic stocks. The
Philippines and several European countries are hoping to harness new forms of
energy from ocean tides, currents, and wind. In the North Sea, Shell Oil
company is planning to build wind power stations offshore. A sea moss (Bugula)
may soon yield an effective treatment for melanomas and lymphomas, two
fast-growing cancers.
But these new discoveries also expose the deep sea to many
of the environmentally destructive practices that have plagued the coasts and
open ocean for centuries. The challenge now is to use the momentum of local and
international progress in science, law, and technology to move quickly to a new
era of ocean management and protect these irreplaceable resources.
