The fabled Yangtze
River, the thirdlongest in the world,
is already dying from
pollution and could be
dead within five
years.
The river’s problems
reflect the water crisis
facing the world’s
most highly populated
country.
China’s 1.3 billion people
are already short of supplies
because of prolonged
drought in many regions —
and much of what remains
has been contaminated by
industrialization.
About 40 percent of all
waste water produced in
China — some 25 billion
tons per year — flows into
the river, but more than 80
percent of it is untreated
beforehand.
Matters have been made
worse by the construction
of the controversial Three
Gorges Dam, which
environmentalists say has
changed the oxygen
content of the river, as well
as creating a huge rubbish
dump in its reservoir.
Yuan Aiguo, a professor at
the China University of
Geosciences based in the
Yangtze port of Wuhan,
said: “Many officials think
the pollution is nothing for
the Yangtze, which has a
large water flow and a
certain capability of selfcleaning, but the pollution
is very serious.”
Industrial waste and
sewage, agricultural
pollution and shipping
discharges were to
blame for the river’s
declining health, the
experts said.
The river, the longest in the world after
the Nile and the Amazon, runs from
Qinghai and Tibet in the remote far west,
through 186 booming cities, before
emptying into the sea at Shanghai. For the
futuristic city’s 20 million residents, the
death of the river could be critical. Lu
Jianjian, a professor at Shanghai’s East
China Normal University, said: “As the
river is the only source of drinking water
in Shanghai, it has been a great challenge
for Shanghai to get clean water.”
It is not only Shanghai that
could suffer if the water of
the Yangtze becomes
unusable. Along with the
Yellow River, it has been
earmarked as part of
China’s ambitious $60
billion south-north water
diversion scheme — a plan
to pump 45 billion cubic
metres (1.6 trillion cubic
feet) of water per year
from southern waterways,
via canals, to the parched
north by 2050.
Environmentalists fear that
unless local governments
and industries become
serious about cutting
pollution, most of the water
shipped north will not be fit
to drink.
Professor Lu said that
contamination has reduced
the number of species
living in the Yangtze from
126 in the mid- 1980s, to
52 four years ago. The
Yangtze dolphin may have
already become the first
cetacean to be made
extinct by humans.
Fishermen complain that the Three Gorges
Dam has blocked fish migration, leading to
a catastrophic drop in catches. Officials
say the change in the oxygen content of
the water from the dam construction is
killing fish. Large amounts of rubbish have
built up in its reservoir, which will fall by
about 40 metres (131ft) each summer,
leaving a huge area of exposed land that
experts fear will fill with pollution, and
breed diseases
