Over-population Overpopulation is where the population of an area is above what is expected and therefore causes overcrowding, loss of natural resources and environmental deterioration. It is thought that the world's population will soon reach a level where there will not be enough resources to sustain the amount we use. Many environmental, social, and economic problems are either caused by or are increased by overpopulation. For example, there is a limited area of arable land and living space in many countries. China is home to 1.2 billion people which is one fifth of the world's population, and shows many of the main examples of the problems that arise in increasingly crowded areas. ...read more.


In many areas, there is simply not enough food to feed the growing populations. Each day 40,000 children die from malnutrition and its related diseases. 150 million children in the world suffer from poor health due to food shortages. Another resource, which cannot keep up with an increasing population, is water. The recent California drought is an example of this. A possible solution to the fresh water shortage is towing icebergs from the polar caps however this is just too costly for many areas. Overpopulation also increases environmental problems such as air pollution, which is extremely evident in places such as the centre of London which is hugely overcrowded. ...read more.


Also, one in six people in Japan (22 million) are now considered elderly and this is expected to increase to one in three people by 2025. This will clearly cause huge economic problems as at the moment, four working people support one elderly person, but soon two working people will have to support one elderly person. However, the main cause of underpopulation is an extremely high death rate compared to birth rate. AIDs, is an example of a major cause of this and therefore a better education and a medical care is the main solution to underpopulation. However, these require huge amounts of money and places such as Africa do not have this. Iden Ranapour ...read more.

    conclude that infanticide was or was not practised in general in Japan. What would be a fair assumption would be to say that infanticide probably was operational in some areas and not in others. However it seems unlikely that infanticide alone, occurring in some areas would lead to the stagnated population that occurred in Japan at this time.
