Just recently in class,I read an article about how rising sea levels can destruct floods and can sink islands.This incident also threaten freshwater supplies in coastal communities around the world.The story begins like this....
As global temperature are melting land ice and ocean waters, sea levels are also rising.The worry is, salt water is contaminating freshwater.People living near the sea suffer because if salt water continue to flow into freshwater rivers, they will not have enough supplies.Without freshwater flowing through the rivers, humans,crops and animals too can suffer,which means there will be many hungry stomachs. Thailand, Israel, China, Bangladesh,Vietnam and the United States have report problems caused by the saltwater.Since 1992,the increase is 3mm per year.The prediction is not clear but the Intergovermental Panel believes that this century it will rise 9mm to 88cm.Ocean circulation,wind pressure patterns,tides and strom can also affect the water level rise in the oceans.Greenhouse gas emission are one big factor because if it is reduce,we can reduce the rate of air temperature that are increasing,by that,the rise in sea levels will eventually slow down.
That's the end of the story..
