Transcripts
kelp is a type of seaweed that is rich
in iodine and alkali and grows in
underwater forests in shallow oceans
across the world including in china an
example is the yellow sea named for the
tinted silt water discharged from major
rivers the yellow sea is vast but part
of it sets off the chinese coast of
shandong and right by the city of
rongchang where half a million tons of
kelp is harvested each year the local
leaf variety distinct to rongchang is
known for being very wide and thick when
the peak season comes around in may and
june every year large bunches of kelp
weighing some five kilos each are
bundled together kelp fields stretching
over 500 kilometers line the coast with
sea and mud flats spread out across the
area it's a sight to behold and an
example of how nature provides for our
needs kelp is not only rich in nutrients
to humans above ground but the kelp
forests that grow below water are
critical to marine life with important
biodiversity and ecological functions in
large amounts kelp ash is used in soap
and glass production and as an
ingredient in carbohydrates that
contribute to products such as ice cream
jelly and toothpaste it can even be
found in health devices such as dental
and orthodontic impressions
as a major kelp hub the people of wrong
term play a big part in how we live with
500 000 tons of harvest annually is the
most important of its kind in china
which in turn contributes 40 to the
global supply
much of the hard work can be found in
the local fisheries where workers gear
up for their peak season in the months
between spring and summer in the fall
they shift their focus from kelp to sea
cucumber which allows them to work for
more months in a year but this also
means new skills like diving down to the
seabed in order to secure their catch
sea cucumbers are important to the
ecosystem
but also considered a delicacy in fresh
and dried forms in chinese and southeast
asian cultures where they're popular in
soups and stews rongchang and other
parts of northern china are critical
supply sources but demand regularly
outstrip supply driving up prices and
putting the species in danger of
overfishing but it provides sustainable
income for fishermen who traditionally
harvest by hand the varieties of sea
cucumbers that are destined for
consumption over generations it
sustained families and communities who
are the bedrock of an entire industry
by winter they again turn their
attention elsewhere sowing seeds for the
next batch of kelp that will be ripe for
picking by may and june the following
year they also use this transition time
to repair and replace their boats and
other equipment it's a year-round effort
even if the harvesting itself is
concentrated across a few months of the
calendar shandong is one of three major
centers for kelp aquaculture in china
the others being futien along the south
east coast and leoning in the northeast
together the three provinces provide for
90 percent of the global production of
kelp in addition to growing demand
because of its health benefits the use
of kelp is also being applied to
medicines and products including
cosmetics dyeing and textile printing
looking ahead the future will surely be
shaped by sustainability and that means
creating a mindful balance between human
consumption economic growth and natural
preservation the idea is to develop
local fisheries towards this goal across
three thousand kilometers of coastline
in shandong while the plan is to use
these waters less for hunting and more
for breeding in line with the ecology
that brings us this goodness to begin
with
