It is explained in the passage that ……………
By 1993, the world's human population had reached 5.5 thousand million and, although the growth has slowed down in recent years, it will be many decades before it stops. The reason why this growth is causing so much concern is that we cannot keep up with the corresponding increase in demand for food, water, healthcare, jobs, education and housing. It also increases the likelihood of damage to the environ¬ment. Much of the growth has been in the poorer countries of the world, but overpopulation is also a problem for some rich countries, including Britain. With a population of approximately 58 million, Britain has 233 inhabitants per square kilometre. Furthermore, it is estimated that the number of people in the country will have increased to 62 million by 2031, at which time it will start to decline again. Populations not only increase because of higher birth rates, but also because of people moving from poor to rich countries, and from the countryside to the towns. In fact the latter cause is greater than general population growth and is creating many problems in the towns and cities, especially in poorer parts of the world.
