based on the following passage.
?
The pollution of Hong
Kong
’
s beaches by oil from a damaged tanker last year recalls
a similar
incident which took place in Britain in 1967 when
the Torrey Canyon,a huge
oil
tanker,split
in
two
and
caused
disaster
in
coastal
of
fishes
were
killed,sea
birds
hopelessly
fouled
with
oil
and
coastal
holiday
resorts
put
out
of
business
for
several
weeks.
As
a
result
of
this
particular
incident
scientists
are
becoming
restless at the thought of Britain
’
s inability to cope with national disasters
on
a
large
reason
for
their
concern
is
that
technology
is
rapidly
outstripping(

)man
’
< p>s ability to control it.?
Oil tankers,for instance,have been
allowed to get bigger and bigger without
sufficient
thought being given to
emergency
braking and
manoeuvring ions at sea continue,but little effect
has
been made to develop safety devices
as effective as those used for
aircraft.
?
Scientists
were outspoken in expressing their concern during
a recent meeting of the
British ous
approval was voiced when the leading speaker urged
that
a
permanent
national
rescue
services
should
be
established,equipped
for
any
emergency
and
ready
to
move
off

most
discussion
was

release
of
radioactivity
from
a
nuclear
power
does
not
need
a
particularly
vivid
imagination
to
visualize
the
other
possibilities
would
be
the
effect
of
a
jumbo-jet
crashing on a large chemical plant
handling destroying liquids?Could the tapping of
natural gas
lead
to
any
form
of
collapse?Suppose
a
lorry
full
of
a
highly
poisonous
chemical
crashed unseen into a large
reservoir?Dams
can
burst,abnormal conditions can lead to massive
electrical blackouts.
?
An
intensive
study
of
such
possibilities
could
at
least
reduce
the
effects
of
future
example,it would mean that a number of technical
alternatives
(such as the choice
between detergent or chalk for dispersing oil)
could be examined
and tested in advance
so that specially trained expert would know
exactly what action
was needed in a
given emergency.
?
