http://www.travelchinaguide.com/china_great_wall/\n\nNo one can tell precisely when the building of the Great Wall was started but it is popularly believed that it originated as a military fortification against intrusion by tribes on the borders during the earlier Zhou Dynasty. Late in the Spring and Autumn Period (770 BC - 476 BC), the ducal states extended the defence work and built "great" structures to prevent the attacks from other states. It was not until the Qin Dynasty that the separate walls, constructed by the states of Qin, Yan and Zhao kingdoms, were connected to form a defensive system on the northern border of the country by Emperor Qin Shi Huang (also called Qin Shi Huangdi by westerners or the First Emperor). After the emperor unified the country in 214 BC, he ordered the construction of the wall. It took about ten years to finish and the wall stretched from Linzhao (in the eastern part of today's Gansu Province) in the west to Liaodong (in today's Jilin Province) in the east. The wall not only served as a defence in the north but also symbolized the power of the emperor.

The Berlin Wall kept people IN not OUT. The wall we would like erected at our border is to keep OUT illegal immigrants and anyone else who wants to enter our country without detection which includes terrorists, criminals and drug dealers. The people who want to enter legally would have to be screened. That would also cut down on the chances of speading dangerous diseases into the USA. It is a good way to HELP deter illegal immigration. Border security would take care of those who manage to get in illegally. The Border security should have the right to shoot on sight anyone who crosses at any point other than those designated.

China was ruled by emperors. They justified their rule using a concept called the mandate of heaven, which is similar to the divine right theory of European kings.  Depending upon the time period, their economy was for the most part based on agriculture, and they kept themselves pretty isolated. Government philosophy was based on Confucian philosophy

The East German government, which was a surrogate of communist Russia, built the Berlin wall.  The purpose of the wall was to separate the two Germany's, but more importantly, to keep the east Berliners from escaping to the west.  To freedom.\nThe wall idea was conceived by the communist party.  It was finally torn down because the soviet influence and financial resources had gone south.  The Russians could no longer subsidize east Germany.  In the meantime, other pressures were being brought to bear.  In Poland, the labor unions were turning on the communist party.  In Russia itself, the idea of a democracy was becoming a reality.  These events overwhelmed the communist party and it was forced to capitulate to the will of the people.

To the people of China(which I am one of), it represents their glory of achieving a great architectural wonder; a memoir of their magnificence. It was originally created to guard China against Mongols and other foes, though.

How many of you out there remember this same BS when the Soviets were building the Berlin wall?  Ask the Russians and Germans how much they benefited from building their wall to keep out undesireables.  Oh wait, the Soviet Union is no more and the Germanys are back together and the wall came tumbling down.\n\nGo read some history about the great wall of China.  Why it was built and why it didn't work either.

Too big for it to ever have been built.\nToo many animals to ever carry enough food.\nToo many animals for the smaller ones not to have drowned/suffocated in all the waste they animals would have produced.

They built the wall to protect the Ming Empire from raids from other tribes like the Mongols and the Turkics. There are some claims that as many as 1 000 000 people died while building the wall, which is why the Great Wall has been nicknamed "The Longest Cemetery on Earth"\n\nI hope this helped...good luck on your speech!
