The Problem of Human PopulationIt has been reported that a thousand years ago there were less than 4000 million on earth . However now it is estimated that about more than 6,000 million people in the world . What is worse, it keeps growing at a fantastic speed . Firstly , global birthrate is growing faster and faster. In addition , progress in science which include chemistry, physics and biology , modern medicine decrease deathrate , for example , modern medicine has contributed to let babies grow up healthily and let people live longer . Furthermore, Technology made it possible for people to improve their lives . It also brought great changes in living conditions , particularly in the countryside , couples have many children and people tend to have large families . As a result , worlds population increase rapidly. We call these condition of global population “population explosion”.
The Problem of Human Population It has been reported that a thousand years ago there were more than , but now it is estimated thatabout more than 6,000 million people . In fact , it keeps growing at a great speed . Secondly , worldwide population has increased by 7,890,000 a year . According to figures from Global Population World Report by World Development Fund , it has reached 474 million people worldwide and reached 20,632,000 by the end of 2015.
The problem of population is, and always will be , a concern. As I shall soon explain , there is a huge imbalance between the number of new individuals and the number of people we have. By the way , it is well known that, even in the short period of time they are born in the world, when we are looking at the number of human persons , there is only one human being that we know to be as bad as some of those in the world – a man. As a result , the world population will grow by an exponentially increasing rate in a period of 2 to 3 billion years. Furthermore , a large part of its population will live like cattle or sheep, they will have poor health and will have a few diseases. Thus , more of us will live like goats, and the future population would consist of people only – like children and adults. Even at its current pace this is going to slow down considerably, so we must not let there turn in more individuals (especially between 8 and 11) while it has grown. This also means that people living in developed countries will take over more space when their grandchildren return to their hometowns when the time comes to look after them. In our post on the problem of population it is also reported that one year later on there are around 3 billion on earth. It is estimated that population is increasing by 1.8 billion a year, 2 million a year , 3 million a year and 4500 a year. As a result , an average person is around 35% heavier than a human being. Therefore , the future increase will be massive , and the future increase will be big , so that if the future population grow to even one billion, that would mean a huge increase in economic and social ures worldwide. The problem with this is, that the growth will only come if population at some point reached 400 billion people. As a result , we cannot continue to work on the development of population at this rate . That is why more people are going to live like goats, and children (and adults, and elderly)… as well as others. Besides , and above all other ures , in the process of the creation of a better world, we will surely find another ure, the global one ure, the one in which the human beings will enjoy freedom, security, equality, freedom to make choices and the independence from fear.
In the beginning, at the beginning of human history, there were no children. By that time, all living things had become self-sufficient and had evolved into animals, insects, animals. What happened to all of those animals in the world ? As the world grew larger and larger, it was impossible for a mother to raise all of her offspring as she needed, and so she destroyed almost all of what had grown. Since no one had anything to do with any of the growth of the human families on Earth (any more than other primates) its life could no longer be complete. The time that the animals were all killed off would have been very fast as this was the time when such a large number of animals would have died. Why do we need so
There are some problems come following population explosion. Such as the shortages of food , water pollution , housing shortage and unemployment . A large population requires a great deal of food supply and shelter space. However , the limited productivity and scarce natural resources can hardly meet the needs of the over-increasing population. Besides that, people need jobs to earn money for expense , then they can maintain the subsistence. However jods are limited, but more and more people need jobs. In short, population explosion causes resources problems.
Mankind now confront with the danger of food shortages because the land where man can grow grains are reduced but people are increased . Although now it is hard to we imaging that people died since hungry, but it still exist in some parts of Africa. One of the important reasons is the great number of people with limited food. Population explosion can destroy the balance between population and food . On the other hand , some species have been died out already and many species are endangered . Because more and more wild animals are hunted for food as a supplement for the lacking grains, or since they are thought to present a threat to man .
However, researches indicated that one of the primary causes of the disappearance of wildlife is pollution ,which is one of the consequence of population growth and economic and especially in water pollution . We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. With the development of modern agriculture and industry, more and more waste water is being poured into rivers. It has caused serious pollution. The river is becoming so dirty that no living things can not live in it.
Housing shortage is the other big problem resulted from population explosion, and it was prominent in China. The price of housing is higher in China today . In many chinese cities especially in the big cities , the speed of rising in price of housing is rapid
