Our world today is faced with many major threats. The most dangerous threat of all is war. Just as Virgil--a Roman poet said "Wars, horrid wars!" War is very terrible. Everybody hears it with fear. In a war,thousands and thousands of lives will be lost and a large amount of money will be wasted. It brings us untold damage.
War is repugnant, peace is welcome, but I have to admit that there hasn't been any period in the history during which the world was really at peace.
Each war starts for a particular reason, but there are a number of steps countries can take to prevent its outbreak. One main reason for war is the difference in ideology. In order to control the world, capitalist countries never stop trying to tam over the communist governments. Land ownership is also a reason that countries declare wars on their neighbors. For example, if oil is found on the land in one country, that land may be claimed by another country, for historical reasons, and the latter is likely to declare war in order to recover the land containing oil.
Although war has been inevitable in the course of human civilization.,we can still reduce the possibility of war to the lowest extent.
To prevent the war, countries should try to solve their differences through international organizations such as the United Nations or by other peaceful means. In addition, the world people should never stop criticizing those warmongers and send them into prison if they dare launch new wars.
If you and me call on world peace together,I believe our world will be better in the future.
Just do it!
That's all!
Thank you!
