BOTTLED WATER UNDER ATTACK
The Water Companies Association (WCA) has claimed
that bottled water costs 700 times more than tap water,
but is often of inferior quality. The chief executive of the
WCA pointed out that although bottled water advertising
often associated the product with sport and health there
was no truth in this link. The reality, she said, was that
the packaging of bottled water was environmentally
damaging, since millions of empty bottles had to be
disposed of in rubbish tips. 2% of samples of bottled
water failed a purity test conducted by the Drinking Water
Inspectorate, while only 0.3% of tap water samples failed
the same test. Labels on bottled water often referred to
‘spring’ and ‘natural water’, which were meaningless
phrases. In addition, bottled water was imported from as
far as Korea and Kenya, which was a waste of resources.
These criticisms, however, were rejected by the British
Soft Drinks Association, which argued that bottled
water was a successful business founded on giving the
customers choice, quality and convenience.

research to the development of vaccines’. Read the text and

NEW LIGHT ON THE PLAGUE
The plague, which first struck Europe in the sixth century,
was one of the great disasters of history. In the fourteenth
century it became the Black Death, when it may have
killed one-third of the entire population. The microbe that
causes the disease lives on rats, and is passed on to
humans by the bite of a flea. It still survives today, though
outbreaks are less deadly: the World Health Organization
receives reports of 3,000 cases annually. Scientists
believe that the microbe was originally a stomach
infection, but evolved into a more lethal disease about
1,500 years ago.
Now the genetic code of the plague bacterium has been
‘read’ by scientists; a total of 465 million ‘letters’ of DNA.
They believe that this will help in the development of
