Visual pollution has a greater effect on people than you may think. I remember when I went to a big city, I was really scared because so much graffiti on the building's wall. Then I looked up, and I saw a lot of power lines over my head. Although they were not dangerous, I still felt unsafe since I thought they might fall down. These things prevented me from enjoying the beautiful sights of the city.

Looking at the messy room caused me so much stress that I did not want to study. Then I decided to clean the room and put my thing in their proper places.

Almost a hundred thousand people were killed and half a million homes destroyed as a result of an earthquake in Tokyo in 1923. The earthquake began a minute before noon when the habitants of Tokyo were cooking their midday meals. Thousand of stoves were overturned as soon as the earth began to shake. As a result , small fires broke out everywhere and quickly spread. The fire engines were prevented from going to help because many of the roads had cracked open. It was impossible to use fire fighting equipment as most of the water pipes had burts. Consequently, over ninety percent of the damage was caused by fire rather than by the collapse of buildings
