Population growth 1750 to 2150 World population growth


The line graph shows us a population Growth in Richer and poorer countries between years 1750 and 2150. This study done by UNITED NATIONS - world population prospects, the 1998 revision and estimates by the population reference Bureau.


In the first two centuries the population growth was very slow in poorer and richer countries. In 1750 the total world population was less than one billion in both poorer and richer countries. The population of less developed countries was three or four times greater than that of more developed countries. From 1950 to 2000 the population growth was very fast. By 2000 the population growth in poor countries was 5.1 billion, but only about 1 billion in richer countries. They estimate that by 2150 the total world population will be around or over 10 billion in poorer countries, but for richer countries it will remain about one billion. It may even drop slightly.

Finally, the graph shows that the total population has increased and will continue to increase in both countries rich and poor and the increase will be more in the less developed countries than in undevelopment countries.

Mobile phones & Driving

People have been arguing about using mobile phones while driving: whether it should be banned or not. In my opinion I think using mobile phones while driving is dangerous, but it is necessary sometimes.

First I will begin with the arguments which are against the statement. The main argument is that mobile phones have become an important part of our lives especially here in the UAE. Another argument is that the businessmen need their mobile phones all the time and if they couldn’t use their phones deals will drop. Yet another argument is that mobile phones could help the drivers when they have a problem in their cars especially for old people and women.

There are also a number of arguments that support the statement. The main argument is that using mobile phones while driving is very dangerous and it could lead to serious accidents and that is because using mobile phones distracts your attention from the road and reduces your reaction’s speed. Another argument is that sometimes when the phones ring while driving it could scare you and this could cause an accident. Recent research has shown that the death rate of car accidents in the UAE is very high and using mobile phones while driving is one of the reasons. We should put a strict law for using mobile phones while driving especially when people don’t care.

In conclusion, although there are arguments in favor of the statement there are more arguments against. In my opinion people should use mobiles only in an emergency, and not for chatting to friends.

Traffic congestion and parking problems in Abu Dhabi


Problem & solution essay.

Traffic congestion and parking problems are faced by most large cities around the world, and Abu Dhabi is no exception.

The main overall reason for these problems in Abu Dhabi is the rapidly expanding population. More people means more drivers and thus more cars on the roads. Many of these drivers are young and inexperienced which means more accidents and more hold-ups. Another factor is Abu Dhabi's rapid economic development over the past few decades. More industrialization means more business and so more commercial vehicles, many of them large and slow-moving. There are now many more new, high-rise buildings but they haven't all been constructed with adequate parking space and this has led to massive parking problems in the business district. The fact that Abu Dhabi is an island with limited space for transport development has further added to the problem.

One obvious solution is to improve the existing road network by constructing more bridges, overpasses and underpasses to ease traffic flow. Another possible solution is to improve public transport, with better bus services and a new rail network, as in Dubai with its new metro. Yet another possibility is for the authorities, as in Singapore, to make motoring more expensive, through higher registration fees, restrictions on where and when motorists may use their cars, etc.

The first solution is already underway, an example being the recently opened underpass on Salam Street, near Khalifa Park. Similarly, public bus services have been much improved recently. The problem with regard to greater restrictions on motorists is that many people will see them as an attack on individual liberty and no doubt they would prove unpopular, at least to begin with. With regard to solving parking problems, the existing rules regarding new buildings having adequate parking space, preferably underground, must be strictly enforced.
