The Graying of the World
People in the world are becoming older. We know that before 50 there aren't more people ,but now the proportion of elderly people is increasing and this may create problem for countries.There are a lot of negative effects will happen in future.
First effect,no industrilized country still produce enough childern to sustain population ,so is leading to a steep slowdown in population growth.For example, in America people are living until age 75 ,so birthrate is declining.Also,in China the number of childern are decreasing and the family can't have more than 2 childern.
Second effect, industrialized countries are aging socities.For example, Iran is aging four times than United States.Also, Egypt is aging three times than United States and Iraq is aging 2 times than United States.
Third effect,in America the ratio of younger people supporting old people is declining.For example, in 1946 the ratio was for one old person there are 42 younger support him and today for one old person there are just three younger support him.Also, in 2030 it will be 2 younger support one old ,so one child must support 2 perants and four grand parents.
In brief, that was some effects about the graying of the world.
