A great artistic tradition threatened by greed
This is an edited version of an article I wrote for the WWF website.
For hundreds – even thousands – of years, red and pink corals (species of the family known as Coralliidae) have been a key component in jewellery and objets d'art
in many cultures, from the Americas, through the Mediterranean, Africa,
India, as far as China and Japan. Now, however, this tradition is under
threat because of over-harvesting of the corals, driven by demand in
international trade.
The
ancient Greeks believed that this delicately-branched coral was the
petrified blood of the Gorgon, Medusa, who was slain by Perseus. In
fact, the branching structures are colonies of tiny animals, known as
polyps, set in a hard skeleton of calcium carbonate that is coloured by
carotene.
The
Romans believed that this coral could protect children from harm, as
well as cure snake and scorpion bites, while in Hindu astrology it is
associated with the planet Mars.
The
town of Torre del Greco, near Naples, Italy, can probably claim to be
the leading centre of coral craftsmanship in the world, with several
thousand people employed in the industry there.
Sadly,
however, they are relying increasingly on coral caught in the Pacific,
as the stocks in the Mediterranean have become severely depleted. In the
Mediterranean, colonies of Corallium rubrum of up to
50cm in height were once common; however, now more than 90 percent of
colonies in fished areas are only 3 to 5cm tall and less than half are
sexually mature.
The smaller the colony, the
fewer branches it has. Therefore, since each branch is studded with the
individual animals, known as polyps, that are the building blocks of the
colony (yes indeed, corals are animals that form and grow as a colony), using colony height as
the reference point does not give a true picture of the catastrophic scale of the decline. In fact, a reduction of three-quarters in the
height of the colony represents a much greater reduction in the overall
size, and so number of polyps that it carries. This in turn means that
the capacity of colonies to reproduce themselves is seriously weakened -
in other words, the coral is being fished out of the Mediterranean much
faster than it can replenish itself.
Now
there are signs also of depletion of the Pacific stocks. Data in the
Pacific shows that the quantities of coral harvested have declined from
peak levels of 100-400 tons a year in the late 1980s/ early 1990s to
less than five tons currently.
Clearly,
red and pink corals are in crisis. What is at stake is not only the
loss of one of the beautiful creatures of the ocean, but the end of a
long and proud tradition of human craftsmanship - effectively, part of
mankind's cultural heritage - unless urgent and effective steps are
taken to limit the exploitation of this resource.
Ironically,
while international trade in many other coral species is regulated by
the Convention on International Trade in Endangered Species (CITES),
that in red and pink coral - arguably the most valuable and widely
traded species - remains unregulated. In fact, trade interests have
lobbied aggressively and successfully at two recent meetings of the
Convention to prevent adoption of measures that would have allowed for
such regulation to ensure sustainability and legality of supply.
Therefore, my advice is DO NOT BUY red and pink coral jewellery until the exploitation
and trade of these species is placed on a sustainable footing.
I say this, not because I want to see an end to the manufacture of coral jewellery but because trade interests will have to to accept international
regulation of the trade if the tradition is to survive in the long
term.
Seaweb is the NGO that has at the cutting edge of coral conservation issues. Through its “Too Precious to Wear”
campaign, it has successfully persuaded over 50 high profile designers,
manufacturers and retailers – including Tiffany and Co. – to cease using red and pink coral.
However,
to date, Seaweb’s efforts within its limited resources have focussed on
the United States of America. If this campaign is to be effective, Seaweb needs more resources to widen the scope – at least to Europe and, if possible, to the
fashion industry in Asia.
Only in that way can this unique piece of our natural and cultural
heritage be preserved for the future.
