Population growth in both the developing and developed world is putting pressure on sewage systems and highlighting the need for latrines in rural areas and urban slums.
The country reaches 7 billion people and the country can not hold the world's watse, and that causes problems for the countries with little sanitational areas. With the world's population growing and death rates falling and not enough wastes treatments in the world, we will probably end having some countries having a high death rate due to the sanitation problems. I don't think that the Earth was meant to hold so many people and buildings, and sooner or later people will consider building waste treatment in the middle of the ocean. So we need to spead the world to other countries to reduce their population and maybe keep the waste managment under control.
