The graph shows us some information about the number of farms and farm workers in the U.S for the period 1910-2000.
All the way through, the number of workers was bigger than the number of farms. At the beginning of the period 1910, there were nearly 14 million workers, twice the number of farms which was 6 million. The number of farms gently increased over the next 20 years, while the number of workers fell slightly. In 1970, the number of farms fell to about a half of the number of workers. Also, in this year both the number of farms and the number of workers fell dramatically. In 1980, the information shows that the number of workers and farms stayed steady and decreased gradually until 2000.
All in all, the statistics show the number of farms fell from over 6 million to just over 2 million. Moreover, with the growth of development the fall in the number of workers was more rapid, from over 13 million to just 3 million.

Mobiles in the classroom
In the past , education was a very important matter all over the world. But these days every student uses mobile phones in the classrooms which is distracting the student from concentrating with the teacher. I feel using mobile phones is harmful in a number of ways; I think it is also beneficial in other ways. Now I will outline compelling reasons why phones should be banned in class.
Mobile phones have gone a long way from the days they were used only to make and receive calls .They now have cameras, recorders, speakers, and even internet and their applications can prove to be quite useful in class but only as long as the students are mature enough to use their phones professionally in class for their academic purposes.
The problem with the use of mobile phones in class is that the students can be easily distracted by social chat sites and SMS and the inappropriate use of some websites. The noise of sending and receiving calls and messages will distract not only the individual student but the whole class. Finally, of course, ADMC has notices in all classrooms strictly prohibiting the use of mobile phones, as well as the consumption of food and drink.
All in all,there are so many disadvantages of using phones in classes that most schools prefer to ban the use of mobile phones in their classes but if the mobile phones are used maturely in class then the advantages of mobile phones would be more then the disadvantages just as long as the students are disciplined and have self control.

Water Shortage
The UAE is a desert country, with very little yearly rainfall, and so there is a steady problem of water shortage.
The most noticeable reason for the shortage of water is the fast population growth. More people means more food and this has led to a growing demand for an increase in agricultural production, which in turn means more irrigation and therefore more water. In addition, the economy of the country has greatly expanded over the past 50 years. Industrialization has greatly increased the demand for water. The climate of the UAE makes it difficult to meet the increased demand for water. There is very little rainfall and no surface water makes the situation worse.
Desalination is perhaps the most obvious solution. It’s expensive but the UAE is a rich country. Similarly, making better use of underground water is not cheap but it would help to answer the problem. Dams to store water when it does rain have already been built in Fujairah and Ras Al Khaimah. Charging people more for water, educational programmes in schools and colleges, and national advertising campaigns could also raise public awareness of the problem.
All in all, the UAE gets most of its fresh water from desalination plants. This is the most clear short-term solution. In the long run, however, raising public awareness of the problem and encouraging people to use water more responsibly is the most important factor in solving the problem of water shortages.

Traffic Congestion
Abu Dhabi is a large city. It is the capital of the UAE. In all cities in the world there are traffic and parking problems.The main cause is the population has improved. This is the first cause for traffic and parking problems.
In Abu Dhabi every home has more than one car. The second cause is economic expansion. There are more marketable vehicles .Also, the weather in summer is not helping people to use the cycles for transport. Finally, parking is the big cause of traffic congestion. There are no more parking spaces for people to park their cars.
On the other hand, the solutions for these problems are as follows. Make sure each building has adequate parking. Each apartment should have parking. Also, improving public transport will help the government to solve the problem. For example increase the number of buses or build a metro to decrease the number of car users. One solution is to increase the age of license holders. In Abu Dhabi most accidents involve young people aged 18 to 24. Finally, the last solution is to improve the obtainable road system. Like build more bridges, overpasses and underpasses.
All in all, the main problem is the parking. The best solution is to build the parking buildings. Also, improve the public transport like raise the number of buses and build a metro, although I think a metro will cost more and buses are the best idea to solve the problems.
