The world is said to be divided into three parts there's the rich, the middle class, and then the poor.
Well this theory is wrong in fact there is one more and we classify those people as less then poor.
These type of groups live in places we call slums which are run down areas with tons of people
crowded into small areas like shacks. Slums have a negative impact on human population's because
the inhabitants of the slums can get easily sick due to pollution in the air, governments do not always
help these people living in slums so they have tho take car of them selves, and there are high rates of
death during natural disasters due to poor shelter structure and the fact that the structures they live in are
so close tho each other. Slums have the highest rates of pollution making living almost impossible, people
living in slums always have a risk of dying to small fevers or colds.
