 FLOOD

Nowadays, flood often attack many big city. This disaster surely dangerous for people who live around here. Maybe like appear many diseases. The examples are diarrhea, itch, dysentery, or skin disease. Flood also can disturb people’s daily activity. Such as bad transportation strip that can complicate people who ride to go to office or student when go to school. Why it is so? There are many arguments about something that causes flood.

Firstly, many people throwing trash in the river. After that if there is a heavy rainfall and the water level is higher than the river bank or the dams, the water comes out from the river, and river can’t absorb too much water, there will be flooding. It occurs because the river has fully of trash.

Secondly, there are many trees and even a jungle changed into human settlements. This is causes flood because there is no absorption to the soil. People who cutting these tree maybe do not know what the effect of cutting so many trees is.

Third, Poor water management. When the dams are poorly constructed and maintained, they can easily collapse and these results in flooding.

 The, because Snowmelt. Because of global warming, the temperature of this year is higher than the temperature of many years ago. The ice caps melt in spring, and the water goes into the sea. The water raises the sea level, and makes the river level rise. When river level rises, flooding may occur.

Population pressure also causes flood.
Because of large amounts of people, everything needs more, like food, land, and wood. Soil erosion happens more often and increases the risk of flooding.

Based on these arguments, we can give recommendation that we should throw trash in the dustbin. And we should care to our environment. One example is we should decrease deforestation and cutting tree wisely.  And the last we must give attention for our water management. If there is a problem, we should as quickly as possible repair that.
