MISSING SUN
Pollution in many of the world’s cities is becoming a major health problem. One of the worst affected is Beijing, the capital of China. Air quality was dangerously low on fifty-eight days last year. The winter months are especially bad. This is the time of year when more coal is burned to heat people’s homes. There is also less wind to blow the smog away. At this time of year, pollution levels are sometimes twenty times higher than the WHO (World Health Organization) considers safe. This
causes illnesses and on the worst days old people and children are advised to stay indoors. Visibility is sometimes so bad that motorways have to close
because ofthe danger of accidents.
In early 2014, some newspapers and websites
showed a frightening vision of the future. On a
smoggy morning, residents of Beijing watched the
sunrise. However, as the real one was hidden, they
had to do this on giant TV screens. The smog was so
thick that the real sunrise was completely invisible.
While this might seem shocking, the film of the
sunrise was nothing unusual. The screens show
adverts all the time. The one that the people were
watching that morning was for a holiday company.
The same advert is shown quite often, whatever the
weather. Either the photographer was lucky or he
knew exactly how the image would look and waited
until he got the photo he wanted. Although the news
reporting was inaccurate, it might have done
something to raise awareness of how bad the
problem has become. Politicians, too, have finally
decided that something must be done to reduce
pollution levels.
The first idea is to reduce the amount of coal that
people use. Factories will also be moved to areas
further away from cities. Another target is older,
more polluting cars. The worst offenders will be
banned. In their place, greener and cleaner forms
of transport will be encouraged.
Will these changes help? The Chinese know from
experience that it is possible to improve air quality
very quickly if necessary. Before the 2008 Olympic
Games, pollution in Beijing was reduced greatly. As
well as reducing traffic levels and closing factories,other methods to reduce pollution were used.
These included pouring water onto roads to reduce
the amount of dust flying in the air. To help with
this, scientists were even able to make clouds
drop more rain. Since then, things have got worse
rather than better but, at last, the government
seems to be determined to do something about
the problem. For the people of Beijing and other
large cities this will make a huge difference to
their lives.
