Well, actually the population increces every each year, with the young people, and yes there is a 70 percentage of the young adults than older humans, however there are many advantages, and disadvantages as well, one of the healthy items about this, that the young generations are our future, but anyways it depends on their attude, and a personality to be a good, moreover smart, and make any useful things to thier society, to make their county grow, and trying to make it a modern. The biggest disadvantage is based on that, the young adults are starting to make a family at an early age while they are still a children in an adults skin forthemore, they makes a lot of members at their own family, i think the government must change the sitengs of the country law and warning the people for make at least four children, even it is more healthy for livers of the country, sometimes humans are should think about our world, and future too.
