smog
The rains are finally over or so it seems and we are greeted again
by clear blue morning skies. Driving from my residence into town
early in the morning however, the skies are not that clear and blue
at all. In fact there is a thick dark grey cloud hanging over the
city. This was not as evident during the rainy season as its appearance
was mixed with the rain clouds but it was there nevertheless. It
is there every day and all the more noticeable when coming from
the outskirts of the city, moving towards the centre. “What
is that?” asked my children on the way to school. “That
is smog.”
The word smog was formed early during the last century in London
from the smoky fog that covered that city as a result of industrial
air pollution, more especially from large amounts of coal burning.
Smog is a problem in a number of cities around the world and is
harming human health. Senior citizens, children and people with
heart and lung conditions like bronchitis and asthma are especially
susceptible. Smog can inflame the airways, decrease the lungs’
working capacity and cause shortness of breath, pain when inhaling
deeply, wheezing, and coughing. It can cause eye and nose irritation
and it dries out the protective membranes of the nose and throat
and interferes with the body’s ability to fight infection,
increasing susceptibility to illness. If any of these symptoms are
familiar in your surroundings, they could be related to smog or
air pollution. Think again.
Worldwide air pollution is responsible for large numbers of deaths
and cases of respiratory disease. Gases such as carbon dioxide,
which contribute to global warming, are gaining recognition as major
pollutants.
While major stationary sources like factories are often identified
with air pollution, the greatest source of emissions is actually
mobile, mainly automobiles. This is no different in Addis Abeba
as there are hardly any factories in the city centre as compared
to the ever increasing numbers of cars, most of which lack modern
exhaust filters. In addition, meals are cooked in many homes by
burning wood sending vast amounts of domestic smoke into the air.
Cars, buses and trucks with diesel engines seem the worst polluters
as they spit out huge amounts of black exhaust right into the face
of pedestrians walking along the road. It is not only a lack of
modern exhaust filters; it is also a lack of maintenance, while
many cars are assembled at sea level and not tuned to the altitude
of Addis Abeba where the oxygen/fuel mixture is negatively affected
by the thinner air.
I came across a news item of two years ago about another city, affected
by smog. This is what it said:
“More than 1,600 people have been taken to hospitals as pollution
in the capital reaches critical levels, health officials have said.
Hospitals have reported increased cases of heart attacks and breathing
problems, while many residents are complaining of fatigue and headaches.
Public offices and schools have been closed in an attempt to reduce
traffic and clear the city’s blanket of smog. Authorities
have warned of thousands of casualties if pollution levels persist.
There is no wind or rain and the dirty air is trapped on top of
the city by the mountains surrounding it. The health ministry said
the extent of deaths and casualties from pollution were “not
less” than those in a recent plane crash, which killed more
than 100 people. However there is no official confirmation of any
smog-related deaths. From Monday, cars will only be allowed into
the city centre on alternate days, depending on whether their number
plates start with odd or even numbers. Authorities have blamed the
severe smog on emissions from cars. It is estimated that up to 5,000
people die every year from air pollution in the city.”
Admittedly, the smog in Addis Abeba may not have reached such serious
levels yet and the numbers of cars and polluting industries are
still far less than in other cities around the world but we are
moving in that direction. And continuing in that direction without
taking measures will one day result in a situation as described
above.
Imagine the effect such a situation has on the economy, which we
are desperately trying to boost. Many workers will be less effective
while health related costs will become a burden for society. Meanwhile
we will continue to contribute to global warming while we should
find ways to reduce emissions and thus reduce global warming, which
is believed to be a major cause for climate change of which we increasingly
see the effects regionally and locally. More frequent and serious
periods of drought, followed by floods are situations that do not
contribute to economic growth, do they?
Talking about our environment, smog is not the only result of pollution
in the city. There are other obvious signs of pollution, which negatively
affect the environment we live and work in. The other day, I had
a visitor from abroad in my car and he just couldn’t believe
all the dirt he saw lying around town and along the roads. Surely,
the way we deal with domestic and industrial waste is an issue here.
And while there are some initiatives in collecting domestic waste,
this doesn’t go much further than taking it out of sight to
a dump somewhere else in the neighbourhood where it lies rotting
and stinking away a number of days before taken to the city waste
dump. The health hazards are obvious. Do I have to mention the smell
created by the abattoir? We all love to eat meat in Ethiopia but
why the slaughter house has to be such a sore in the eye and cause
such inconvenience beats me. Investors are putting up buildings
in the area but will have a hard time finding tenants for their
offices I guess, again negatively affecting economic development
in the neighbourhood.
I could go on but I guess I made my point. Pollution negatively
affects our health and economic growth. Something needs to be done
about it, in terms of legislation, yes but probably more so by investors,
industrial sectors and individuals becoming aware of their contributions
to it and developing a consciousness to change our attitude towards
the environment we live and work in.
